It had started some days earlier...

Gary's mind flashed back to the day Bernie had caught him having incestuous sex in the back of the Super Surf Van.

"Actually, Joyce," Gary explained to Bernie's mom, "things kind of got started before that day. I got walked in on when I was messing around with my friend Peter Walker."

"Messing around sexually?" Joyce asked. His girlfriend's nude mother looked calmly at Gary from her chair in Bernie and Joyce's living room.

"Yeah. When the door opened, I had my dick up his butt."

"That would definitely count as sex," Joyce said.

Gary thought about that day while trying to figure out how to explain the rest of how things happened.

Gary's friend Peter Walker had come over to visit, and they had started messing around in Gary's room like they often did. Things rapidly progressed to Peter and Gary taking turns sucking each other's cocks. When Peter said, "Let's do it," Gary put on a condom and they moved into one of their usual "blast-off" positions. Peter kneeled on a towel in Gary's armless desk chair, holding onto the seat. Gary stepped behind him and lubricated his friend's anus and his own penis. Gary pointed the tip of his cock through the sparse blond hair between Peter's buttocks, and easily penetrated his friend's ass. Gary and Peter adjusted their position a little for comfort until Gary could start thrusting. They built up a slow and steady rhythm, Gary holding Peter's buttocks while he dicked his friend's ass. Not much was said. Mumbles of "Uh-huh", "Fuckin' good", and "Yeah" were as much as Gary and Peter said to each other.

Gary heard someone call through his door to ask something. Gary called back something, but he was really too distracted to say anything coherent as his thrusting cock swelled up inside his friend's butt. Peter did his best to stay silent while Gary kept fucking him.

Gary's door opened quietly. Gary's desk was against the side wall, so from the door, there was a clear side-on view of Gary standing naked with his hard cock up the butt of his equally naked friend Peter Walker. Gary and Peter didn't notice the intrusion right away.

The two young men's blond hair was damp and their faces flushed pink as they pumped toward climax. Gary's good-sized cock moved slowly and steadily in Peter's ass, staying close to halfway in. Peter's erect, circumcised penis bounced with Gary's strokes. A thread of clear fluid hung from the tip.

"I'm gonna do it," Peter whispered.

"Fuck yeah, do it," Gary whispered back.

Peter circled a finger and thumb behind the head of his penis and jerked twice. His cock head swelled and white shots of come painted the towel. His face, ears, and shoulders flushed completely pink. Peter kept his mouth shut, and the only sound he made was a faint whimper.

As Peter came, his anus squeezed down on Gary's penis. Every pulse of Peter's ejaculation transmitted itself to Gary as a firm squeeze on his cock shaft. Gary felt his own orgasm coming and gritted his teeth to keep quiet. A whimper marked Gary's own rising climax. His hips moved by themselves for the last few thrusts, stabbing his cock deeper into Peter's butt. Warmth flowed through Gary's body as once again he blasted off into his friend's ass. He slumped across Peter's back.

But as Gary leaned forward across Peter's back, he turned his head sideways and saw the door to his room closing. His eyes opened wide. 'Busted!' he thought.

He didn't say anything about it to Peter. They cleaned up, Peter and Gary thanked each other for a good "game", and Peter went on his way.

Neither his mom or dad said anything that day or acted at all unusual. But late that evening, after the family had gotten ready for bed, there was a knock on Gary's door. Gary immediately thought it must be whoever saw him dicking Peter that afternoon.
