In his bathtub, Arnold was still sitting with Helga, and still having fun. Helga was still sitting behind her boyfriend, and she have him company while Arnood was enjoying her naked body like his own living pillow.

"I'm glad you're enjoying this, Arnold." said Helga.

"same." the boy agreed with her. "This sounds weird, but I feel we should have done this before we went to South America."

"Better late than never, Arnold." Helga sang. "Better late than never "

"Heh. That's true."

They both sat down in silence for a minute while having their bath together, and they were still glad they were having alone time with no one else to interrupt or ruin their moment of peace while they sot naked as lovers.

Helga had another idea, and she licked her again. "Arnold, let me try something else on you." she had a sly smirk.

"What's that, Helga?" asked Arnold.

The girl then slowly got up and laid on her belly, and slowly engulfed Arnold's penis in her mouth, making him grunt and gasp in ecstasy. Her mouth was so soft, so wet, and tender to go with it. He enjoyed a nice moment of fellatio from his own girlfriend and he closed his eyes in relaxation.

"Time to show him I'm better than my sister." Helga thought to herself while sucking. She even swirled her tongue around Arnold's tip and it made him more horny from how tender her to the felt against his sensitive skin. He didn't want to make a moaning sound, because his parents, or the other residents that live within his apartment building would hear him and the secret would be exposed.

This went on for about ten minutes in this bath, and Arnold ejaculated inside Helga's mouth after the pleasure had begun to take its toll on him. It was quite a pleasuring activity, that he ejaculated exactly three times in her mouth, and Helga swallowed every last drop of all his cum.

'Hmmmm, your taste never ceases to please me, Football-head." said Olga.

Arnold smiled. "Glad you like it, Helga."

"Like it?" Asked Helga. "I love every taste of it."

They both got out of the bathtub, let thr water drain and dried themselves off before putting on their clothes. "Listen, why don't you go out first?" Arnold suggested. "I don't want my family to find out you were there with me. And, you might want to be very quiet about sneaking out of here."

"Pfft. Not a problem, sweetie." said Helga. "I am good with keeping secrets."

"Good."

Helga stealthy, and quietly sneaked out of the bathroom, and luckily, Arnold's parents and grandparents didn't suspect a thing about what had happened minutes before. Arnold waited a moment before he exited the bathroom to watch some TV.

His girlfriend joined him and they were watching some cheesy romance movies, which they were not big fans of. "Ugh. I hate these cheesy romantic comedies." Arnold remarked in disgust.

""Tell me about it! Please change the channel." Helga gagged. "But I bet Olga would love this junk. At least we don't really baby-talk like some couples do."

Arnold and Olga looked at one another for a moment, and they both agreed and made sounds of disgust. "Ugh. Of course not. Why would we want to do something as cheesy as that?"

"Yeah. It is so disgusting."

"What are you guys talking about?" asked Stella, who was coming in the living room with Miles.

"Ah, just thinking how stupid these romantic comedies are. The cheesy kissing, the baby-talking." Arnold replied. "Blegh! Mom, I wouldn't be able to stand watching something like that."

"What movies?" asked Miles. he flipped the channel to the previous one, and he recognized a movie. "Ah, the Kiss of Life." he said. "That's one of me and your mother's favorites, Arnold."

"I know." Arnold said with his eyes rolling.

"It was a nice movie to watch in the theaters when it came out." Miles said.

"And it was our first kiss." Stella sang. "I mean, isn't that right, Miles?' she was starting to baby-talk with her husband now.

"Oh yeah, my Stelly-welly." Miles replied.

"Oh no. Not that." Helga complained. "Come on, Arnold. Let's get out of here."

"Sure. We can go to my room." the lovebirds did just that, and hung out in the bedroom. "Did your parents ever do that kind of stuff before?" Arnold asked her.

"Wait... you're kidding, right?" Helga didn't exact know how to answer that. "Arnold, you know my parents long enough to see how... abnormal they are."

"Yeah, point made."

"So... about you with my sister," Helga cleared his throat. "I understand that Olga really likes you, and... I know you really like her so-called perfect body. For that, I will let you and Olga do... 'it's together."

"Thanks Helga. But we know that my heart belongs to you. Nothing can ever separate my love for you."

He pulled out the radio and played a song on it. It was the song: "Save your Love" by the 80's metal band: Great White. As the song played, he was singing the lyrics to her and she was so touched to hear it from him.

"Oh Arnold." Helga sighed before pulling him for a kiss.

It was long, and passionate and they were locking their lips to each other. This song playing on the boombox was a perfect one to broaden the mood between these lovebirds.

The Next Day

Arnold was studying at a test with Helga in her flat this time. Of course, being dysfunctional, her parents could care less about what Helga is doing right now, but they do care greatly about what Olga is doing, considering the fact that they treat her like their little princess.

After some studying, Arnold was hanging out with his girlfriend, and watching some TV together. Whike watching, Olga noticed them and sat next to her little sister. "Pardon me, but my favorite channel is on." said Olga.

"Don't tell me it's..." Helga watched her sister flick the channel to what appears to be a cheesy sitcom called: "Boyfriends." She groaned at looking at it. "Ugh. Boyfriends again? I'm out of here." Helga got out the couch and went to her room to not watch that show.

Arnold was alone with Olga, and he was slowly getting hard just by sitting with her. "So Arnold, since you are here, why not... have some fun in the shower?" she giggled. Arnold's dick grew harder hearing that. "I mean, you saw me naked before and I was thinking we can... make this right."

"Well... that sounds nice." Arnold said. "So sure. But what about your parents?'

"Mother is napping in her room, and daddy is getting ready to leave for his business today."

"Good." Arnold then followed the hot young lady upstairs and she close the door, turned on the shower head, and she slowly took off her clothes. She smiled and laughed at Arnold's reaction. The boy then took off his own clothes, and Olga went inside the tub first. She teasingly signaled Arnold to come to her with her fingers and Arnold did just that.

""Come with with me, sweetie." she murmured. "I can be your pillow." They both sat on the tub, and Arnold was feeling this nice sensation as her body was keeping him warm. Before he knew it, he felt his penis being jerked around rapidly by her. "Uh-oh! Think fast." she teased before resuming the handjob.

After a while, Arnold ejaculated five times, and she didn't stop there. She kept on going.
