Ryan sat on the couch as his sister and her boyfriend sat on the other end. Mike was pawing at her heavily as they didn't even pretend to watch the movie. Ryan could only think of his girlfriend Liz as he watched Taylor stick her tongue down Mike's throat.
After another ten minutes of watching the two of them paw like animals, Ryan slunk upstairs to his bedroom. It was torturous still being in high school and not able to spend time with his girlfriend like Taylor could spend time with Mike. She had barely scraped through high school and was now in community college.
Their dad was still not home as he stripped down and climbed into bed. Their mother was already in bed to be at work early the next day. Dad had had orders to Korea but rejected them so he could be there for Ryan's graduation. Unfortunately, Dad seemingly was never home because of work on the base.
Muting the volume on his laptop, Ryan started a favorite video of his as he lay in bed. It was of two guys and a girl. Liz would most likely be disgusted if she knew of his fantasy. She had turned 18 a month ago shortly after he had and still told him to wait. She wasn't waiting for graduation. Ryan didn't know what she was waiting for.
He had managed to finger her a few times and eaten her out once since her birthday. She hadn't done anything with him yet at all. He would love to be railing her like the guy in the video as one of his friends like Paul pushed his dick in and out of her mouth. He could definitely picture it as she rode one dick and sucked the other.
Paul always seemed to come to mind when Ryan watched a video like this. Something about Paul pulled in his mind. Maybe something could happen between the two of them as they fucked Liz or even Heather. Heather was the dream girl around town. She had graduated with Taylor and was one of her best friends.
Ryan kept stroking on his cock as he thought about maybe Heather and Liz together worshipping his cock before he pounded Liz and then Heather. He groaned loudly as he came. Grabbing some tissues he cleaned himself up before zoning out.
It wasn't long before he heard the familiar sounds of Taylor and Mike. Once again he felt himself get aroused to the sounds of his elder sister getting fucked. It made him feel dirty and awkward but he didn't care anymore. He pushed his boxers down again and jerked off again to the sounds from next door.
Sunday's were always boring around the house. Dad had slipped in at some point and slipped back out before Ryan woke up. Mike had also disappeared when Taylor came downstairs in nothing but a camisole and panties. She had her nipples poking out of the camisole as she sat down to eat breakfast.
Ryan texted Paul to join him for some video games. Paul agreed to come over later when he was free. His little sister was turning 17. They were almost Irish twins, with him being 18 for a few weeks now.
The rest of the morning dragged on as he waited for Paul to show up. Once he was over, the two got lost in playing the game with minimal conversation. Dinner time raced at them when they found some leftovers. Mike's car was now in the driveway and he was nowhere to be seen in the house. Neither was Taylor easy to find.
Retreating to his bedroom, Paul and he began looking up rumors about their favorite teams and video game reports. That lost its appeal after a little bit as the missing two were found by noise. Ryan was sprawled out on his bed as he heard Mike praise Taylor's oral skills.
"Why is your sister still with that loser?" "I'm not sure, man." "I would be a much better choice for her than him." Ryan eyed Paul. "You know I would!" "Yeah, you're right." "You know I am! I have intelligence. I have a personality. I have a lack of being Mike."
"You really have a crush on my sister." "Taylor is hot. You're parents did good. You bagged Liz, so you know it's true." "I guess so." Mike was soundingly returning the favor Taylor had given him now by the sounds barely audible through the wall.
Paul was adjusting himself through his pants as he sat at the desk. "Fuck it man. I haven't cum in a few days." "I jerked off twice last night." "Liz still not putting out?" "Nothing. I ate her out last week." "You told me." "You need to experience a blow job, brother. Not just your hand doing the deed. I mean, it works well enough. It just isn't the best thing. Or even close to it."
Paul had lost his virginity a few years ago to his ex and was still looking for his second. Ryan was envious of his friend. Paul was really fixing himself now above his pants.
Taking a risk, Ryan pushed his pants down and whipped his dick out. Paul joined him in depantsing. Ryan started stroking his cock as Paul joined him on the bed and did the same. Measuring himself mentally, Ryan noted Paul was a similar size. He wasn't sure which was bigger. The ginger shaved though and had no pubic hair unlike Ryan. They furiously stroked to the manic sounds of pleasure Taylor shouted out about.
Looking at his friend, Ryan leaned in and kissed him. There was a definite difference then kissing a girl but he had no qualms about it. It turned from a kiss into something more though as Paul moved over him. Soon they were thrusting against each other, cocks rubbing against each other.
Ryan called out first as he erupted. He paused as Paul kept going. Paul groaned a minute later as he came as well. It was a new experience feeling someone else cum against his skin. They collapsed against each other.
Liz and he had made out some more after school. He had gotten a finger in her and made her moan much like he heard Taylor moan. She had stroked him through his shorts and made him cum. It was the furthest the two of them had gotten so far.
Paul and he had talked and agreed they were open to more of the same in the future. The house was empty like normal as he walked in. Scurrying to the bedroom, he stripped off his sticky underwear and ran to the shower. The shower was a blessing as he cleaned off his seed. He heard his sister come in.
Ryan freaked out a moment as he realized his clothes were in the room. Then he remembered he could just use a towel and go back to the bedroom that way. Turning the shower off, he toweled off and headed back to his room. Taylor just waved as she saw him enter the room.
She was in booty shorts and a tank top with knee high socks. His erection tented the towel as he raced inside. He desperately needed to jerk off again. After finally being brought to orgasm by Liz and seeing how his sister was dressed, his arousal was firing on all cylinders. It was almost torture.
