Chapter 6: Not What Was Supposed to Happen

"Ow! What was that for?" Sirius screamed.

"That is for being a complete arse-hole! Don't even pretend like you didn't deserve it" Lily screamed back. "Just tell me one thing".

"What?"

"Why?" Suddenly she was shy and vulnerable.

Aw man! How can I even consider being mean to her when she looks so vulnerable. No! I have to do this for James. "You want to know why I turned you down? Fine. The reason I wouldn't shag you in the broom closet is because I find you unattractive. There! I said it!"

All of a sudden the shyness was gone and the sarcasm was starting which was her way of being defensive. "Thank you! Thank you so much for keeping me from making the biggest mistake of my life! I can't believe I even considered ever hooking up with you". She laughed to her self.

"Oh, please! It would have been the best shag of your life and you know it!"

"Yeah, okay. You sure you didn't run because you were afraid that I would tell everyone that you are awful in bed? Which, I'm sure, is actually probably true".

"At least I would be able to hide my secret. Everybody in the whole bloody school knows that you're a prissy, goody-two-shoes, virgin" he calmly spat out at her.

She slapped him again. Ugh! Not even James got me so mad that I would resort to physical violence! "Oh! So you think that just cause I'm a virgin I wouldn't even be worth the time and energy to shag when I practically force myself on you?"

"Do you really believe that I would gain the reputation that I had if I wasn't amazing in bed?"

"Well you are rich. I have no doubt that the sluts who are interested in you wouldn't mind a few extra galleons to keep their mouth shut".

"Oh yeah?"

Before Lily could even respond his lips were on hers in a forceful kiss. She just stood there, frozen to the spot for a few minutes before the finally kissed back. She definitely wasn't expecting this. His lips were soft and gentle even through the roughness of the kiss.

He laid back down on his bed and brought her down with him. He then gracefully flipped them over so that she was on the bottom. He was pleasantly surprised by her. She was actually an amazing kisser and just had this way about her that was so inviting. He ran his hands up and down her sides, each time getting closer to her breasts, testing her to see how far he could go before she stopped him. At the same time he broke away from the kiss to trail his lips across her jaw and down her neck where he stopped to suck and nibble lightly on her pulse point.

She couldn't believe that this was happening. She thought for sure that the first time that she would be doing anything even remotely close to anything like this it would be with a guy that she was in a committed relationship with and definitely after waiting for a while. Yet, here she was. Every time he got closer to her chest she had to stop herself from grabbing his hands and pulling them all the way up. When he finally landed on them she had to fight off a moan. His experienced hands were warm and comforting as he gently kneaded.

They're bigger than they look he thought. Not too big though. The perfect size to fit in my hands. He too had to suppress a groan from escaping from the feel of her soft boobs in his hands. He had always secretly wondered what it would be like to do this to Lily Evans but never acted on it for James' sake. Now that it was finally happening he couldn't help but grow harder and harder by the minute. This did not go unnoticed by Lily.

She felt his growing erection pressing up against her stomach. It only turned her on more and she was slightly embarrassed by the warm feeling that gushed through her body before finally settling between her legs. She slipped one of her legs between his and ground her hips up into his thigh, needing the friction.

He groaned feeling just how wet she was for him and flipped them over once more so that she was straddling him, her womanhood sitting perfectly on top of his cock. His lips met hers once again as he thrust his erection against her.

Both suddenly feeling that there were far too many clothes restricting their actions they started to undress one another. When he broke the kiss to pull her shirt up over his head he heard the familiar pounding of feet coming up the staircase. He has just enough time to pull the covers up over Lily's head, hiding her from their untimely visitor, before Remus, Peter, and James came barging into the room. Sirius panicked. He would be dead for sure if anyone caught him and Lily together, but especially one of The Marauders and even more especially, James.

"Jesus Padfoot! Think you could give a little warning if you're bringing someone back to the room?" Remus yelled as the three of them all jumped at the sight of Sirius on his bed with messed up hair and a very obvious hidden figure on top of him.

"Yeah! I really didn't need the visual" Peter quickly agreed.

James just started laughing and the three boys looked at him.

"What's so funny?" Sirius questioned, hoping he didn't sound as nervous as he felt.

"Why is she hiding? It's not like girls to ever keep it a secret when they sleep with you" James explained.

Lily froze. Remus and Peter were bad enough but James catching them was a whole new level of awful.

Sirius was quick to think of an explanation. It really isn't even a lie. It's just an exaggerated truth. "Well, umm, she kind of has a boyfriend" he hesitated, "and even though I know we could trust you not to tell, she just doesn't want to risk it".

"Aw man! You're shagging a taken girl and we won't even get to here the raunchy details?" James whined half sarcastic, half serious.

Serious laughed. "Sorry mate, guess you'll have to miss out on this one. But, uh, if you three don't mind, could you leave? I'd kind of like to finish what I started". He winked at them as they all laughed and shook their heads on their way out.

"Be sure to put up silencing charms before you continue. Just because we won't be seeing it doesn't mean we all want to hear it instead" Remus joked before shutting the door after him.

Lily finally came out from under the covers. "Oh my God!" she exclaimed.

"Yeah, that was close" Sirius agreed. He started shifting around, sure that the moment was over and she would be leaving.

"And where do you think you're going?" she asked seductively.

Sirius instantly grew hard again and smiled at her. "Nowhere. Now, where were we?"

She leaned down and connected their lips once again before Sirius had to break the kiss to pull of her shirt. He massaged her boobs and rubbed her nipples through the thin fabric, making her cry out in pleasure.

"Guess I better do those silencing charms after all" Sirius said before picking up his wand from the bedside table and quickly muttering the spell.

He turned back to her and back to their previous actions. He slowly snaked his arms around her back to the clasp of her bra, looking at her face the entire time, waiting for any sign of disapproval. When he didn't get one he undid the clasp and watched as her boobs spilled out.

She quickly crossed her arms in front of her chest and blushed a magnificent shade of red.

He gently gripped her wrists and pulled her arms away, kissing the skin of each breast as it was exposed until her arms were down by her sides.

"You're beautiful" he reassured her before he dipped his head in and took her right nipple in his mouth while twisting the other between his thumb and pointer finger.

She grabbed hold of his hair and arched into his touch. "Oh Sirius!" Lily moaned loudly.

Sirius switched sides and continued his ministrations.

Lily rolled her hips over his ever growing erection and cried out again.

Sirius groaned and smirked, loving knowing that even something as simple as what he was doing was driving her mad. He trailed his lips back up her chest and neck and back to her lips for a hungry kiss.

She ran her hands down his body, stopping at the bottom of his shirt then running her hands back up underneath, feeling his toned abs and chest. She brought them back down and gently tugged on the edge of the shirt, hoping that he would get the hint.

He did and so he broke the kiss only for a second to take his shirt off and throw it to the floor. He shivered at her touch. Her small fingers were cold yet left fiery trails in their path across his skin.

She kept one hand on his chest while the other one tentatively moved down to his trousers where she stroked him through his jeans. She moaned into his mouth once she felt how big he truly was.

He let out a slight hiss at the feel of her nimble fingers stroking him. He had had this done to him dozens of times prior to this by numerous girls, but Lily was different. It was something about the way that she was so brave in her actions yet scared and shy at the same time.

With shaking hands she clumsily undid his belt buckle, making Sirius take a sharp intake of breath every time she accidentally brushed her fingers under his waist band. She had the belt and button undone and the zipper unzipped when he flipped them over so she was once again on the bottom before smoothly taking off his own jeans then took hers off as well, throwing both into the growing pile of clothes next to the bed, never breaking the kiss.

He kissed down her body to her naval then down the inside of her thigh and calf, expertly missing the desired area, then back up until he was eye level with her womanhood. He kissed her clit through her lacy panties and looked up into her eyes as he sensually pulled them down with his teeth. Once they were off he returned to his spot in front of her core licked up her slit. Her moan and desperate grip on his hair egged him on and so he started rubbing her clit with his thumb while sticking his tongue as far into her pussy as possible.

He could already tell how tight she was going to be and it made him anxious to be inside her. No. Since this is her first time, I'm going to make this all about her. Forget about what I want.

"Ugh! Serious! That feels so good! Oh G-od! D-d-don't stop!" she exclaimed.

He then slowly pushed a single finger inside of her. He started to thrust it in and out when she screamed in pleasure.

"More! Please! I need more!" she moaned.

He went harder and faster before adding another digit into her pussy. "Mmm Lily! Baby, you're so tight!" he groaned out, sending vibrations up her body and bringing her to her climax.

"I'm coming! Ugh! Sirius! O-o-o-h. . ." she screamed out in ecstasy as she rode out the waves of her orgasm.

He lapped up all of her juices as they spilled from her, holding down her hips as the bucked violently. Once he had licked her clean he made his way back up to her face and kissed her hard on the lips.

She sighed in contentment when she tasted herself on his lips which then turned into a moan when he pushed his rock hard cock against her overly sensitive clit. She reached down and started to push his boxers down his legs before he took them off, leaving them both completely naked. Her eyes gaped at the size of him and her mouth fell open. She was finally brought back to reality when she heard Sirius laugh lightly at her reaction.

She smiled at smacked his shoulder lightly. "Hey! Don't laugh at me!" she laughed.

"I'm sorry baby. You are just too cute" he smiled back at her.

"Nice save" she teased. "Seriously though. . ." and she bit her lip nervously, staring down at his thick, eight inch cock.

He gave her a quick kiss. "It'll be alright Lily-Bean".

"Will it hurt?" she asked vulnerably.

"Yes. At first," he answered simply, "but I promise to be as gentle as possible".

"O-okay" she said, her voice shaking.

"You don't have to do this Baby. If you don't want to or you're not ready or you have any doubts at all then we can stop right here. I promise I won't be angry".

"No, no, no. I want this, I want you" she smiled up at him.

He smiled down at her then positioned his cock by her entrance. "Are you absolutely positive?"

"Yes".

He slowly pushed into he and kissed away the tears that she let fall. "We're almost there Lily-Bean" he cooed. He then brought their lips together in a passionate kiss before he pushed in further and broke her boundary. He paused and waited for her to get used to the new feeling. She rolled her hips when she was ready and he started moving in and out slowly.

He continued at that pace then gradually got faster when she asked it of him until he spilled inside her.

A/N: Did you like it? It took a lot of time to actually write this chapter even though I do take the plot from the movie, because I wanted everything to be perfect. Tell me what you think, reviews are what keeps writers alive.
