Nate was sitting at his desk in his bedroom, researching some ideas for a paper he needed to write for his English lit class. Nothing was sparking any ideas and he sat there, staring at his computer, sullen. Deciding he needed a little push to motivate his mind, he opened a private browsing window and typed in the address of one of his favorite porn sites.
It didn't take long to find a wealth of fake step brother/step sister videos to watch. Ever since he and Kaya had been hooking up, he found these videos extremely erotic. He knew they were fake, but still. Every once in a while he'd seek out the amateur videos that made the oral and the sex seem more realistic. He wondered if he and Kaya would ever cross that line.
He found a video labeled "My step bro came in me" and started to watch it with the volume off. He quickly unzipped his shorts and slid those and his boxers off, past his knee, and to the floor. He started playing with his cock to get it hard as the video started up. Soon, he was rock hard and stroking his cock as he watched the two porn stars go at it. The video was only six or seven minutes long, so Nate was going to try and time his orgasm with the male actor.
A few minutes later, when he figured the guy in the video was going to cum, he sped up his strokes. Right when the actor gave a final thrust, the camera positioned behind the actors, catching the pulsing of the actors cock as he came in the woman. That image was enough to send Nate over the edge. He quickly grabbed a couple of tissues from the box on his desk, closed his eyes for a moment, and imagined Kaya knelt before him, sucking his cock. His cock erupted in a torrent of cum. Nate caught most of it in the tissues and once he was done cumming, he wiped the remaining cum off of his dick and then discarded the tissues in the trash.
He closed out the browser and got up to wash his hands in the bathroom. Returning to his desk, he managed to find a topic for his paper and began to write it. About five minutes later, Kaya entered his room and sat on his bed.
"Hey," she said. Nate turned from his computer to face her.
"Hey yourself," he smiled. "What's up?"
"Not much. Don't really want to start homework yet, so I'm going to bug you."
"That's cool. I really don't want to write this paper, either." He got out of the chair, crossed the room, and sat down next to Kaya on the bed.
Classes for both of them had started at the community college two weeks ago, so they were now in the midst of the semester and the homework assignments were starting to pile up. Since their rendezvous in the shower about a month ago, they had still managed to find some time for each other. They had been keeping it to fingering and handjobs, but Nate had noticed Kaya getting a little more brazen lately. The last time they had hooked up, she had come to his room at night, climbed into his bed, took his boxers off, and started to jerk his cock.
Right as Nate was about to cum that night, Kaya had said something to the effect of "Oh! I forgot a rag!" and leaned down and had Nate shoot his cum into her mouth. It was hot, to be sure, but Nate wasn't sure if that meant Kaya wanted to progress things between them further.
As Nate sat on the bed, Kaya leaned over and kissed him lightly on the lips. As she withdrew, she looked at him with a crooked smile on her face. "Did you just jerk off?" she asked.
"What? No, of course not!" Nate stammered.
"It's okay if you did, Natey. You can tell me." Kaya looked right into Nate's eyes. There was no use lying.
"Yeah, I did. I needed a break from searching for paper topic ideas."
Kaya's smile widened. "I knew it! You masterbating fool!" She giggled at him.
"Right. And like you haven't gotten yourself off lately I bet," he said as he poked her side. "I hear you sometimes at night."
"Do not!" Kaya protested. "Besides, if I wanted to get off, I'd just come find you. No sense in doing it myself when I have a perfectly good set of fingers right here," she said as she touched one of Nate's hands.
They both smiled and laughed at each other. Kaya broke the silence. "Wanna get off again?" she asked.
"Would love to, but, I mean, I just did it like ten minutes ago."
"Hmmm..." Kaya said as she pondered this admission. "I could probably get you off if you want me to suck your cock." Kaya smiled, but her face betrayed no sense of joking or kidding, she kept looking Nate directly in the eyes and raised her eyebrows a bit.
"Are you serious? Like, for real. Don't joke about that," Nate said.
"I'm for real. I mean, I've never done it before, so it will probably be terrible and you probably won't cum anyway," she said.
"Ha! I've never even had a mouth close to my dick, so I'd probably cum the minute you put it in."
Kaya giggled a bit and reached out with her right hand and started rubbing Nate's dick through his shorts. She crawled up the bed and kissed him lightly on the mouth. "Well, maybe we'll have to see about that," she said. Then, all of a sudden, she pulled away from Nate, withdrew her hand, jumped off of his bed, and started making her way toward the bedroom door.
"Hey! Where are you going?!" Nate practically yelled.
Kaya turned toward him with a devilish grin on her face. "We can't do that now, silly!" she teased. "Mom and the twins are home right now!"
"That is so not cool!" Nate yelled after her. "Not cool, Ky!"
Kaya went to her bedroom and shut the door softly behind her. After the door latched, she quickly reached into her shorts and panties, and started rubbing her clit with renewed vigor. God, she though, he turns me on so much! I can't get enough of his body! I want his cock in my mouth so bad! Right before she was about to cum and likely need to change her panties and shorts, she stopped rubbing herself. I'll save that for later, she thought.

Instead of staying home for dinner with the family that evening, Nate had made plans with a new friend from his pre-calc class to go out. After calming himself down from the quick interaction with Kaya, he put on a fresh t-shirt and ran upstairs to say a quick goodbye to his mom before he left.
Kaya hadn't known that her brother was going out for dinner, so after the family wrapped up their meal, she returned to her room to work on her homework assignments. After about an hour, her mother called her upstairs and asked her to help get the twins bathed and ready for bed, which she did.
Nate still wasn't home after getting the twins down, so Kaya went downstairs and turned on a TV show to pass the time before she was ready for bed. She hoped in the meantime that Nate would get home and they might be able to squeeze in a little rendezvous. After a little while longer, she peered at her phone and noticed the time was past ten o'clock. Knowing she and Nate both had a morning class tomorrow, she decided to shut the TV off and get ready for bed.
Feeling forlorn that Nate was not home yet, she knew her hopes that she'd be able to get some of the sexual energy out of her before bed were dashed. She brushed her teeth and changed into pajamas. As she laid in bed waiting for sleep to overtake her, she heard the front door open and shut upstairs. Kaya heard her brother come downstairs and use the bathroom, getting ready for bed.
A few moments later, her bedroom door opened a crack, and she heard Nate whisper "Hey, Ky? You still up?"
"Yeah, I'm up," she responded in a tone that betrayed her dismay at him.
"Mind if I come in?"
"Sure...."
Nate crept into Kaya's room and silently closed the door behind him. He padded over to the bed and crawled in beside her. He leaned over to kiss her, but Kaya moved her head away from him.
"You okay?" Nate asked.
"I'm fine," she responded.
"Ky, what's the matter?"
Kaya stared at him through the darkness of the room. "I don't know, Nate, what do you think might be the matter? Could it be that you didn't even tell me you were going out tonight and then the minute you get home you crawl into my bed expecting to get jerked off or something like that?"
"Geez, Ky, it's not like that," Nate started.
