Title: "Leave the lights on"

In the last chapter: The P.S.218 students arrived at Big Bear safe and sound, except for the two blonde stepsiblings who had to experience quite the embarrassing experience when they were caught sleeping on each other during the train journey. Despite Helga's complete lack of interest in Sid, who was still obviously trying to get her attention, he did score a few points with her when he brought a bottle of rum to the field trip, which resulted in a misunderstand between her and Arnold when he suggested she shouldn't drink.

The misunderstanding was cleared up soon, but it reminded the blondes what they had experienced the night before and what their bodies were still yearning after having been interrupted. They kept their feelings at bay though and despite Helga's mesmerizing singing, that wasn't what made Arnold jump her by the end of the night; it was the fact that he had been hitting the bottle after Sid had been flirting shamelessly with Helga for the entire evening.

Chapter 14: "Wanna do me again?"

Arnold had never woken up feeling quite like this; his head was throbbing, his throat was sore and the rest of his body felt numb. All in all, he was beyond nauseous. He groaned as he tried to move with very little success. When he tried to put his hands to his face, only his right hand made the short journey. He mumbled in confusion as he turned his head and saw Helga lying next to him with her head using his arm as a pillow.

In the back of Arnold's mind, the word deja-vu appeared while the front of his mind was blank. He just stared at the sleeping girl in front of him, noticing that she was still wearing the shirt from last night, but that it was crumbled and untidy this morning.

Arnold was slowly entering a state of panic. "Helga." He whispered and looked around to verify they were alone before he shook her shoulder. "Wake up, Helga!"

The blonde girl stirred slowly and opened her eyes lazily. "Arnold?" she questioned with a yawn. "What's wrong - - "

"What happened last night?" Arnold asked in a frenzy.

Helga blinked, clearly awake now. "Huh?"

"I… I don't remember anything…" he admitted nervously and guiltily. It was clear what he was already asking, but he voiced his concern anyhow. "Did… Did we, um…"

Helga was quiet which Arnold wasn't sure how he felt about. She looked at him pensively, almost as if considering her answer, but surely there was only one answer?

Then Helga chuckled to Arnold's confusion. "You don't remember anything because nothing happened." She answered.

"R-Really?"

"Really-Really. You were drunk off your ass so I carried you in here. You kissed me for a while in your drunken stupor, but then we fell asleep." Helga explained and Arnold sighed in relief. "Don't worry. I didn't take your man cherry."

"Not funny!" Arnold insisted before Helga gave him a peck on his lips.

She then stood up and moved towards the door. "I'll sneak out and see where the others are. They all know I took you to bed last night so you just stay here and seem oblivious, ok?" she told him before she headed out.

Yeah. Oblivious; I can definitely do that. Arnold thought before letting himself fall flat on his back.

Helga's modest plan worked like a charm. Most of their classmates had indeed crashed in the living room and were therefore completely unaware of where Helga had slept during the night. They woke up simultaneously when the teacher used a horn to wake them up. She was clearly in a sour mood and was in no shape to play kindergarten teacher so she told them to do however they pleased until it was time to go home. Since most of the teenagers were hung-over from last night, they agreed to simply stay in and relax.

The trip home was without any trouble and the two very exhausted blondes were met with their equally blonde parents who weren't tired whatsoever. Much like before their kids left, they asked for their help for the wedding plans. They had been so busy they even forgot where their kids had been on the field trip. Needless to say, the gang from P.S.218 went to bed early that night.

Wednesday morning, it was time for gym class as usual. Helga and Arnold hadn't had time to be alone whatsoever thanks to both the school, their friends and their parents. They had finally put their foot down Tuesday evening when Miles had woken them up from their sleep to ask about the flowers. Miles and Miriam finally realized what a toll the wedding planning was taking on their children and promised to leave them be for a while and plan the wedding themselves.

That didn't mean that both Arnold and Helga weren't tired for the fifth day in a row when it was time for gym class. Both of them were changing with their eyes only half open. There was a huge difference between them though; while Helga never woke up until she was done changing and the class started, Arnold woke up in the boys' locker room.

The blonde boy's head was constantly falling downwards as he grabbed the hem of one of his usual plaid shirts and pulled it over his head. He realized it'd be easier to unbutton it when he hit his head and started doing that with his eyes still closed. He could hear the other boys' voices, but he wasn't listening at all. As soon as his shirt came off though, he noticed that the boys' voices went louder.

Arnold turned his head to look questioningly at the boys and his eyes finally opened properly when he saw their shocked faces. "What?" he questioned worriedly and looked around, half expecting a spider to fall down on his hair any second.

"Dude…" Sid said with his eyes almost wider than his nose. "What happened to you?"

"Huh?"

Gerald snickered as he poked on Arnold's arm and kept eyeing his torso. "Are those… hickeys?" he asked in disbelief.

Arnold's eyes widened considerably and he looked down at himself. Sure enough, he could see red marks on his chest and abdomen. "What?!" he shrieked perhaps too girlishly and walked towards the mirror to look at himself. He put his hand to his neck, noticing that the hickeys were significantly darker and richer in number there.

"Are those hickeys?" Harold asked in disbelief with a huge grin on his face.

"Well, those sure ain't mosquito bites!" Stinky bellowed and started laughing.

"My, my, Arnold. You have failed to mention to us you were seeing someone?" Eugene asked curiously, his smile far more innocent compared to his peers'.

Arnold's exhausted brain was trying to wrap around what he was looking at. Those were definitely hickeys and the only person who could have planted them there was the same person he hadn't even kissed since Big Bear. Big Bear… Arnold thought and remember Helga's words: "You don't remember anything because nothing happened. You were drunk off your ass so I carried you in here. You kissed me for a while in your drunken stupor, but then we fell asleep."

"I can't believe her!" Arnold bellowed in a high-pitched, but low voice. She lied to me! If she had enough time to make these, there's no way all we did was kissing!

"Her?!" the boys shouted as if they were surprised.

Oh, crap. Arnold thought and turned to look at the boys. He was being drowned in questions about the girl who had made the hickeys and he had no idea how to answer any of them. "One at time!" he begged even though he was only trying to stall. He couldn't answer their questions about the mystery girl; no way.

"Why didn't you tell us you were seeing someone, man?" Gerald asked with a bit of hurt in his voice.

Arnold sighed guiltily. "It's, uh… very new." He lied. Or was it new? When did this even start? When did it truly start?

"It's new?" Sid asked incredulously as he eyed Arnold's hickeys. "Dude, what kinda crazy broad did you hook up with?"

Arnold frowned at that comment. "She's not a broad."

"Well, those hickeys weren't made by a lady." Harold countered and started laughing with the other boys. "She's clearly marked you as her own."

Arnold blushed and looked over his shoulder at his reflection, eyeing the hickeys on his back. "Marked me…" he mumbled shyly.

"Oh, yeah. You know what they say about hickeys, right?" Harold asked as he patted Arnold's shoulder. The blonde boy shook his head and Harold grinned at him. "They are a person's way of telling others to stay away."

"Huh?"

"It's like when animals piss on their territory. It means: stay away, this is mine!"

Arnold groaned at the disgusting metaphor, but couldn't help but feel a sort of happiness bubbling in his stomach. He was still angry though, both with Helga and himself. Why had he gotten so hammered he couldn't remember a single thing and why did Helga lie about that night? What did happen?

"Hey…" Sid said with his signature perverted smirk. "Do you have hickeys anywhere else?"

Arnold blinked. "Uh… I-I don't know. I've been so tired the last couple of days, I haven't really noticed anything…" he admitted and looked down at his pants. He quickly pulled them off and looked at his reflection in the mirror again.

"Oh, my God!" Harold shouted in clear amusement as they eyed the obvious hickeys around his hips.

"Are there some under your boxers too?" Sid asked in hilarity and jokingly reached for Arnold's boxers. The blonde quickly stepped away and jogged towards his clothes. "Oh, come on. We're just kidding, Arnold. Seriously, you're lucky. I wish I had a girl who would do that to me."

Arnold frowned considerably at Sid's words; said girl was after all the one Sid was currently hitting on. He felt a little guilty, but mostly he was just embarrassed.

"Wait. If you have hickeys there… did she suck you off?" Harold asked in awe.

Arnold choked on nothing but air and he turned to glare at his friends. "Could we please change the subject?"

The boys gawked at each other. "That's a yes!" they declared and started bombarding Arnold with questions again.

He was saved by their gym teacher though who knocked on the door and asked them what was taking them so long and threatening to make them do ten extra laps if they weren't out of there within a minute.

It's a redundant detail, but Arnold was naturally anything but focused during gym. His eyes kept darting towards Helga who was blissfully unaware of both his embarrassment, confusion and rage. He couldn't believe Helga had lied to him about what had happened and why? Well, perhaps because he was being completely hysterical about the thought of having done something he couldn't remember, but still. She should have told him the truth.

Arnold wanted to confront Helga as soon as possible and planned to do so during lunch, but Gerald got ahold of him before he could get ahold of her. "Hey, can I talk to you?" Gerald had asked in the hallway with his hands shoved into the pockets of his sweatshirt; his unconscious sign of being in a bad mood – sad or angry was never certain.

Arnold sighed and nodded before following his best friend towards the school yard. He should have known Gerald wanted to talk. Arnold had never had a proper girlfriend and now, out of nowhere, he was apparently sleeping with a girl. A girl Gerald had never heard him talk about. It was extremely out of character for Arnold not to confide in his best friend, which had been a hard thing not to do, but everything had been so messed up that he hadn't had it in him to confess to Gerald at all.

Once Arnold and Gerald were out of sight around the corner of the school yard, the taller boy turned and crossed his arms. "It's not so much you didn't tell me that annoys me as much as you not trusting me with this." He told him in a hiss.

"It's not a matter of trust, Gerald!" Arnold bellowed unhappily. "I was trying to forget it myself, honestly. This… This whole thing is so messed up and I - - "

"This girl…" Gerald interrupted thoughtfully and bit on his lip. "Do I know her?"

"Wha… W-What do you mean know her?"

"Don't play dumb with me." Gerald growled. "I've had a feeling since your slumber party, but I wasn't sure… I also thought my best friend would trust me enough to tell me that he is banging his own sister!"

Arnold started scowling. "First of all, we're not banging. Trust me." He said with a groan, sighing at the reminder. "Second of all; I didn't try to hide it from you specifically or something. This thing between me and Helga happened so out of nowhere! It-It escalated so quickly I-I didn't even consider telling you."

"Why not?" Gerald asked sadly. "I'm your best friend, dude, we've known each other since preschool. You know me; I don't have enough moral to judge you for what you and Helga are doing. If anything I'm a little shocked that you're doing this kind of thing with any girl at all."

"What's that supposed to mean?"

"Well, I never took you for the kind of guy to fool around with a girl." Gerald admitted, which Arnold frowned in confusion at. "I mean, unlike me, you have some serious morals, Arnold, and I just thought - - "

"Whoa-whoa, wait. Helga and I aren't… w-we aren't… We aren't doing this because… I-I'm not fooling around with her!"

"What?" Gerald questioned and then his eyes widened in realization. "Oh, my God…" he said and moved closer to Arnold, inspecting his friend's face. "I thought she was just your rebound girl after Lila or something. Then again, that doesn't seem like something you'd do either. But I thought maybe Helga just agreed or whatever…"

"That's not what this is!" Arnold hissed. "I-I can't even tell you when it started. It's a snowball effect; one thing led to another and before I knew it, I… I, uh - - "

"Fell in love with your own fucking stepsister." Gerald stated and shook his head in disbelief. "You've always had a thing for girls you can't have."

"That's not what this is!"

"How do you know?"

"Because I met Helga before I knew she was going to be my stepsister!"

Gerald blinked a couple of times in confusion. "Wait…" he muttered and then shook his head. "What? What are you - - What are you talking about? Start from the beginning, would you?!"

And that Arnold did. He told Gerald about that fateful meeting in the bus where he had met Helga for the first time, he told him about the dinner at Chez Paris and he told him about how he had gone back and forth from liking her to disliking her for a while before falling so hard for her it physically hurt. He told him about their first kiss, about his confession, about what she had admitted to him and finally, what had happened at Big Bear lake – at least the parts he remembered.

Gerald had been silent through the whole thing and didn't react except for an occasional question, but that changed when Arnold finally finished his bittersweet tale. "Whoa…" was the first word out of his mouth and it took a while before he said anything else. "Arnold… I love you, man, but… but you really are a jinx."

Arnold rolled his eyes. "That's all you got from what I just told you?"

"No, but that's the essence… Of all the girls you could fall for, in comparison to all the girls you have ever fallen for, Helga sure is the worst one yet."

"What do you mean?"

"She's gonna be your stepsister, man! If Miles found out, he'd have a freaking heart attack! You could be risking their marriage." Gerald insisted, but Arnold just closed his eyes and shook his head stubbornly. "Man… you really like her." Gerald stated and massaged Arnold's shoulder soothingly. "What's your plan? Are you gonna ask her about Big Bear?"

"I have to… but I'm afraid what she's gonna say… What if we did do something, Gerald? I mean… what if we did something more? I don't like the thought of not remembering the first time doing that… and I'm scared Helga lied to me because she's insulted that I don't remember."

"She knew you were drunk off your ass that night; there's no way she has a right to be angry."

"M-Maybe not, but I still hate myself for not remembering… I'm never drinking again." Arnold swore, which Gerald chuckled at.

Arnold kept trying to confront Helga on their way home, but it never happened. As soon as they met outside the school, Miriam had called her and started talking to her about going dress shopping sometime later this week. Helga was clearly not keen to the idea of joining her mom on a shopping spree to find both Miriam's bridal gown and her own bridesmaid dress. As soon as Miriam had mentioned the color peach, Helga had screamed like a pig at her to Arnold's clear amusement which earned him Helga's hand on his head as a way of punishing him.

Helga had barely hung up on Miriam when they reached their house and were met with their parents in the door. "Oh, sorry, kids!" Miles said when he almost bumped into them. He ran past them, holding his coat in his hand.

Arnold blinked in confusion. "Where are you going?" he asked when he noticed that Miriam was moving just as frantically even though she was still inside the house.

"Our wedding planner called us and said that the person who schedules the weddings for Bel Air Hotel told her there was a cancellation here in spring so we - - "

"Whoa-whoa, wait. I thought you already settled on a venue?" Helga questioned in confusion.

"But it's Bel Air Hotel, Helga! We can't possible miss an opportunity like that! We're going to meet the wedding planner there to look over the place and decide whether we want to accept or not." Miriam explained.

"But… Bel Air Hotel…" Arnold mumbled. "Isn't that in Los Angeles?"

"Yes, that's why we need to go… now!" Miles told Miriam who hurried out of the house, causing both her daughter and stepson to almost fall when they stepped aside to make room for her. "We need to stay in Los Angeles for the night so you two will have to take care of the house in the meantime. We'll be home sometime tomorrow. You can take care of yourselves, right?"

Helga and Arnold looked at each other and the girl couldn't help but smirk. "I'm… sure we can think of something to do." She replied innocently.

Arnold gulped at the hidden meaning behind her words, but decided to ignore them for now. "S-So, you two are just going to randomly go to Los Angeles to look at Bel Air Hotel and we won't see you until tomorrow?" he questioned.

"Oh, it'll be fine, Arnold." Miles said and gave Miriam the keys so she could unlock the car. He put his hands on his son's shoulders. "Miriam has always dreamed of getting married at the Bel Air Hotel and I really want to make her happy so we have to go. Ok?"

"O-Ok, I'm just…" Arnold said, but shook his head. Why am I complaining? He thought, wondering if it was because he was suddenly nervous by the thought of being alone with Helga… for an entire night even. "Never mind. Just drive safely, ok?"

"We will." Miles said and pecked his son's forehead. "We'll be home tomorrow. You two behave, ok?"

"What else would we do?" Helga asked sarcastically.

Miles chuckled halfheartedly at her joke, obviously in too much of a rush to listen properly to her. "Goodnight, you two!" he shouted before jumping into the car. Miriam simply waved before the car before jumping in as well.

"Goodnight indeed." Helga muttered as she and Arnold waved at their parents driving away. "I think I'll head to bed right now." She said and took Arnold's hand, pulling him inside and pushing him against the door. "Wanna join me?"

"I - - " Arnold said, but his voice was muffled by Helga's lips on his.

He almost sighed in relief as if he had just returned home after being away from years. Despite the passionate kiss, he felt calm in her arms. The temptation was great, they were truly alone for the first time since forever, but he had to ask her about what had happened.

"Helga." Arnold said after pulling his mouth away from hers, but she continued kissing him on his throat, which caused him to groan. With determination, he grabbed her wrists and swung her around until she hit the wall next to the door.

She was looking at him in shock, but it faded into excitement. "Ooh, good start." She said with a bit of mockery in her voice before starting to bite on her lip in expectation.

Arnold's breathing was already ragged by the thought of continuing this, but he shook his head violently. "N-No… Helga, that's not what… I have hickeys." He finally admitted.

She looked at him in confusion, but then her eyes traveled to his neck and noticed the bruise there. Oh, whoa… Real subtle, Helga. She thought and looked at Arnold guiltily. "And now you're wondering why I lied." She stated and whipped her hands out of his grip.

"Yes, I am and can you blame me?" Arnold asked a little angrily.

Helga crossed her arms. "Well, I didn't lie to you, Football Head! I meant it when I told you that we didn't have sex."

"But we did do more than just kissing obviously. I have hickeys everywhere!"

"Oh, that's bullshit."

"I have hickeys under my boxers, Helga!"

Helga blinked a couple of times before hissing. "Crap."

"Yeah, crap. The boys saw it during gym!"

"What?!"

"I've been so tired because of dad and Miriam's constant nagging about the wedding that I didn't notice them until they pointed them out. Now they keep asking me who the broad I'm hooking up with is!"

"Broad?"

"Their words, not mine." Arnold explained and sighed as he ran his fingers through his hair. "Helga… why did you lie? And what did happen?"

"Nothing - - "

"You're lying."

"Let me finish!" Helga hissed and sighed again. "Nothing we haven't done before… also, you did faint in the middle of it so that wasn't a lie."

Arnold felt sick to his stomach. He kept trying to force himself to remember, but his memory was one blank space. "And why did you lie about that?"

"Because I knew this was how you were gonna react." Helga admitted and leaned back against the wall, putting the sole of her foot against it as well. "I knew you were going to feel guilty for not remembering and I wanted to spare you for that pain… and I didn't think of the hickeys, I'll admit."

"That just makes me feel worse…" Arnold said and sunk down to the floor.

"That I didn't think of the hickeys?"

"No, that you lied to protect me! Now I can only be angry with myself." Arnold explained in frustration and put his hands up to his face.

Helga slithered down until she was sitting next to him. "How about not being angry at anyone? Arnold, you were drunk, you were crying and I couldn't resist you. I'm sorry."

"Crying?" Arnold questioned and looked at her.

"Oh, uh, well…" Helga said and cursed her own name for telling him that. "You were upset that Sid kept flirting me and… that he could and you can't because of our parents. I've always been weak to tears, but seeing you like that… it broke my heart."

Arnold saw something soft in Helga's eyes when she said that; something he hadn't seen before. She looked at him in a sort of vulnerable way he hadn't thought she was capable of. Then he realized her words and sighed.

"I… I'm sorry… I think I showed a really pitiful and embarrassing side of myself at Big Bear…"

Helga opened her mouth to talk, but nothing came out. Ever since Big Bear she had been thinking a lot. She had wondered why his crying had bothered her so, she had wondered why she couldn't resist him… She had wondered many things and had come to an unlikely conclusion she wished to share, but feared to do so. She still wasn't sure if she had come to terms with her recent discoveries. Nevertheless, she wanted Arnold to smile at her again…

Helga put her hand on Arnold's cheek and moved his head until he was looking at her. His beautiful green eyes almost seemed as if he looked through her. She leaned closer to him, stopping for a mere second before her lips touched his gently. She hoped she could convey what she wanted him to know through this simple action, but she didn't know whether it had worked or not. She leaned back until their lips weren't touching anymore, waiting for his response.

Arnold closed his eyes and did more than just respond; he kissed her himself. The tip of her fingers grazed his ear and he shivered at the ghostly feeling. How does she do that? He wondered as he felt his worries fade away as if by magic. All he needed was a kiss from her and he was in heaven.

It wasn't until Helga's lips disappeared from Arnold's mouth that he opened his eyes. She took his hand gently and helped him stand up. With her eyes locked loyally on his, she led him up the stairs and towards their rooms. She heard him gulp nervously, presumably in realization.

"You choose." Helga stated when they were standing in the middle of the hallway.

"Huh?" Arnold whispered. He had hoped Helga would take the lead as usual. He felt so nervous all of a sudden that he feared he would be clumsy or awkward.

"You seem nervous so I figured you should get the chance to take some initiative." Helga told him honestly. She could see he was nervous, but she refused to hold his hand through this; well, at least metaphorically speaking. He needs more confidence. So… maybe I should be a little mean? She thought. "Choose; my room or yours?"

To say that Arnold was confused would be an understatement. Why was she asking this of him; if she wanted him to be less nervous, she should have taken the lead! "Um…" he mumbled and looked between their rooms. "I don't really care, but… you-your room?"

"Ok." Helga said, grabbed his shoulder and turned him around until they were both facing her door. She waited, but he didn't do anything. "Open it."

"I-It's your room. You open it."

"You chose this room so you should open the door. Are you really that shy?"

I don't think shyness covers this… Arnold thought as he felt Helga lean against him.

"Or would you prefer to do it here… standing up?" she asked in a whisper. Arnold visibly shivered at her words and had to focus on grabbing the door handle and opening the door. "See, was that so hard? Criminy, I'm starting to wonder if you really want to do this."

Those words pushed a button inside Arnold he didn't know he had. He grabbed Helga's hand behind him, pulled her inside and used her back to close the door by pushing her against it. She blinked in surprise and he smirked.

"What did you call it…?" Arnold wondered sarcastically. "A good start?"

Helga blinked once more before she smirked. Arnold smiled smugly back before he kissed her without closing his eyes so he could watch her reaction for as long as possible. She didn't close her eyes either though, perhaps out of defiance. She tangled her fingers in his and finally closed her eyes though as if surrounding to him. He lifted her arms above her head and started kissing her jaw. He traveled down her throat and suckled on the taut skin there.

"Are you planning to give me a hickey as well?" Helga asked in a low voice.

"The temptation is there." Arnold admitted in a whisper against her throat.

She shivered. "We're done with gym this year…" she pointed out just before he kissed her skin again, this time sucking more harshly. "Did I even have to remind you of that?"

"No."

"You were gonna do it anyway, weren't you?"

"Yep." Arnold agreed with an almost feral grin as he went back to Helga's eyelevel.

"You are such a brat." Helga teased before he kissed her lips. His hands followed her arms to her shoulders and down her sides to her hips. "Strange…"

"What is?"

"We finally have the time to take things slow, but… I don't think I want to." Helga admitted in a pant.

"That's the good thing about having time…" Arnold said with a gentle smile and unzipped her sweatshirt slowly. "We can do it as many times as we want."

Helga blinked. "Ambitious, aren't you?" she asked with a smirk.

"Nah…" he answered as his hand caressed her cheek, his thumb grazing over her lips. "I've just been wanting this for so long."

Helga smirked before she opened her mouth and bit down gently on his fingertip. As soon as she did that, he moved to kiss her in urgency as his hands moved to her breasts, cupping them softly. She inhaled so sharply that her stomach hurt from the sudden change of space. She closed her eyes, enjoying the still alien sensation of Arnold's hands on her chest. Her tongue moved out of the safety from her mouth and coaxed his into opening as well. He obliged enthusiastically while his hands started to experimentally roam on her chest. He had touched it before, but not like this.

Helga lifted her thigh and rubbed it between Arnold's legs, causing him to stop their kiss in order to groan. "No more nice Helga." The blonde warned before her hands clasped around his cheeks and her lips clashed against his. She pushed him until he hit the bed and fell onto the mattress with her straddling him.

That was nice Helga just before? Arnold wondered in awe. The blonde girl grabbed at the hem of his t-shirt and pulled it up over his arms and head. As soon as it was gone, he pulled her down to him to kiss her again. His hands went behind her head, grabbed at her ponytail and loosened it to run his fingers through her hair. She leaned back up, closing her eyes as shook her hair free. It was an enthralling sight.

Arnold moved his hands up Helga's thighs and grabbed at her sleeves to pull on her sweatshirt. She wiggled her shoulders, helping him to get the sweatshirt off and when it was, it landed somewhere near his t-shirt. She put her hands behind her back and Arnold waited as patiently as he could for the bra to disappear. When her chest was bare, her hands went to his lower abdomen and she smirked sensually at him. His hands crept up her naked stomach and her fingers flexed when his hands reached her breasts.

Helga moaned as she started grinding against Arnold, gradually getting him harder and harder and that feeling made her want him all the more. "Pesky pants." She hissed even though she was smiling before she started fumbling with his zipper. She did so, carefully, minding the hardness she could feel under the jeans and pulled them down slowly once they were opened. She was about to move to pull them down, but then Arnold grabbed her by the hem of her own sweatpants and pulled at them as well.

With a short laugh, Helga let herself fall to the side, pulling her pants down to her thighs in the process. Arnold was quick in copying her action and once their pants were off, he climbed on top of her, kissing her desperately. He felt her move her thighs against his legs and up to his hips, pulling him closer to her wetness. He groaned in impatience and stopped the kiss in order to pull her underwear off. She pulled her knees to her chest to help him and soon, she was lying stark naked on the bed.

Arnold marveled in the beauty of the girl beneath him. Helga was breathing heavily, but slowly and the motion of her chest was timed perfect with every breath of air he felt from swollen lips. She chuckled nervously.

"Take a picture, it'll last longer." She joked.

Arnold laughed breathlessly. "Can I?" he asked to which she smirked and slapped him on his shoulder before pulling him down to her again. While licking her lips sensually, his hand moved down her body, making sure his sensitive fingertips felt and memorized every curve they felt on the travel down to her sex. His palm ceased on her hip as his thumb caressed the clit once, earning a gasp from its owner.

Arnold considered asking how Helga wanted him to do it, he considered asking for advice, but his inexperience was overshadowed by his curiosity. Besides, Helga was a very outspoken girl; surely she would tell him if he was going completely off course. So he let his good instincts – the instincts his grandpa had always insisted that he had - take over. His hands fell down her sex once, caressing the heated lips he felt. It felt hotter than he had imagined and his fingers went back, making a circular motion until his fingers were placed near her entrance.

"Go ahead." Helga whispered against Arnold's lips before kissing them.

With a small internal gulp, he wiggled his middle finger inside gently and carefully and all he could think was warm when he reached the end of his finger. He opened his eyes to look at Helga's reaction and the sight was breathtaking. She was biting her lower lip, her head was whipped backwards and her back was arching of the bed in ecstasy.

"Oh, fuck!" Helga cursed when Arnold moved his finger and her hips bucked against his hand.

He laughed in awe. "You look beautiful." He said as he watched and felt her move against his body.

She chuckled even as she panted. "I-I curse and you… c-call me beautiful. You have a twisted sense of beauty." She teased and opened her eyes.

Arnold leaned down to her without stopping the motion of his hand and even added a finger without any warning, earning the most delicious groan he had ever heard from the blonde. "I said you looked beautiful…" he pointed out. Helga smirked as she purred harshly at him before kissing him. He groaned at the way her legs were starting to push even harder against him, causing his erection to rub against her thigh and give him a dissatisfying sort of friction.

"If you keep doing that your fingers will get wrinkly." Helga joked in a hiss.

"You want me to stop?"

"God no… but your fingers aren't enough." Helga explained as she pulled his boxers down.

Arnold moaned as he removed his fingers and helped her kick his boxers off. When they were gone, he grabbed Helga around her hips, pulling her as close to him as possible. He looked between them and then back at her questioningly.

"Time it with my breathing." Helga said encouragingly and grabbed his hands to tangle their fingers together on the mattress next to their hips. He nodded and watched as she breathed in slowly and exhaled. She did so once more before he positioned himself and inched inside of her as she inhaled. He watched her face contort in pain for a mere second and stopped as she exhaled. He moved again, this time faster, imagining it must be like pulling a Band-Aid off; going fast would be better. Helga hissed and forgot her breathing completely. She could feel her eyes prickle with tears that she refused to let fall down and her fingers tightened around his hands.

"I… I-I'm all the way in." Arnold informed, hoping that would make Helga's face go back to the lustful one he had seen a moment ago.

"Yeah, no shit!" Helga cursed though and let her head fall back on the mattress again. She noticed the pillow above her head, grabbed it and threw it on the floor.

"Do you… want to stop?" Arnold asked, wondering what the poor pillow had done.

Helga shook her head though. "No… I was just a little surprised. I always thought girls were being such babies about this." She admitted with a smile and Arnold smiled back in relief. He didn't want to see Helga in pain and he would have stopped if she had told him to, but he was afraid that if they stopped now, he'd have to put ice on his crotch later. "I… I think I want to be on top though."

Arnold felt his heart skip a beat at Helga's suggestion and nodded enthusiastically. She smiled as he leaned down to grab her and helped her swing the both of them around until she was on top of him. He groaned at the motion he felt around him when they did so and she moaned herself. She leaned up, looked down at him for a moment and then moved upwards slowly and back down. She felt him tense under her, obviously holding himself back from slamming inside of her. She couldn't help but smirk as she felt the pain go away after a few more bucks.

Helga grabbed Arnold's hands and pulled them over his head, leaned down and blew some air on his face. He closed his eyes automatically and blinked a couple of times before opening them. "Go ahead." He heard Helga tell him and he looked at her in confusion. "You can be the one to fuck my brains out this time."

Arnold shivered at her suggestable words. He shut his eyes tight for a moment, felt his endurance fade away and grabbed her thighs. He thrust as deeply inside of her as he could, earning a loud gasp from her and another one when he repeated the action.

"Oh, my… God!" Helga shrieked in shock and moved in perfect synch with Arnold.

Despite the slight sting she still felt, everything else she felt was making her dizzy and warm all over. The sight of sweat running down Arnold's forehead and his chest, the scent of their sexes and the feeling of him inside of her made her moan uncontrollably.

Helga leaned down and kissed Arnold, ignoring that their teeth bumped at first and wrapped her arm under his neck. He reciprocated the kiss enthusiastically as his arms went around her hips to hold her closer. He stopped their kiss though and moved his head until his mouth found her breast and his tongue licked it. He had never felt so happy to be shorter than her when he heard the high-pitched moan she made as he kissed her nipple.

The boy could feel Helga's thighs and arms shake in harmony with his own as he pushed her upwards. She moved obediently and kissed the top of his head once they were both sitting up. He let go of her breast and looked up at her with half-hooded eyes which matched her own. They sat still for a few seconds before they moved again, this time in a steadier, but not any less passionate pace.

Arnold could feel, to his regret, that nature was about to take its toll on him. He could feel his orgasm approaching and he hated it because he was finally holding Helga like this and he wanted to keep doing that forever, but his body wasn't as strong-willed as his heart.

"H-Helga, I'm about to…" Arnold warned and looked up at her with his chin resting on her breast.

She smiled at him. "M-Me too." She told him, which was what sent him over the edge. His arms wrapped around her waist and he gripped at her hips tightly, almost choking her with his strength. His entire being was only one emotion and one thought as he heard her scream erratically and felt her tighten around him.

Once the mind-blowing feeling subsided, Arnold felt himself fall down on the bed with Helga nestled closely against him. He could feel her heart beat against his own and smiled when he noticed they were in harmony.

"Hey, Arnold…"

"Y-Yeah?"

"I just thought about… isn't it funny that… Miles actually offered us to share a room if we really wanted to stay at Sunset Arms and we said no… and now we're sleeping together?"

Arnold groaned. "Don't make me think right now, I beg of you." He said with a breathless laugh.

"Sorry." She apologized and moved upwards before falling down next to him. Arnold moved his head to look at her and their eyes met. "Whoa…"

"Yeah…" Arnold agreed in a pant and moved on his side to hold her in his arms. To his utter joy, she nuzzled against his neck and rested with her arms wrapped around him as well. He was in Heaven without being dead, he was sure of it. This was total bliss.

"Hey, Arnold…"

"Yeah?"

"Wanna do me again?"

Author's 2nd note: Now, some of you who have read my former stories might be thinking: "Does this mean we're getting close to the end?" since in my former stories, whenever Arnold and Helga have had sex for the first time, it's in the last chapter or second last chapter xD I can tell you that NO, this is definitely not the end!
