Sucking his own cock.

Gary finished reading Bernie's confession of sneaking off to watch him. His just-spent cock twitched at the thought of Bernie watching through the window that day, pink-faced and shocked but turned on.

There was a P.S. under another sealed fold. Gary opened it.

"P.S.: Mom says it's OK to do it at our house."

Gary looked up at Bernie's mom Joyce, nude and slightly sweaty from her recent self-supplied orgasm. She looked back at him with an even, friendly gaze.

"Oh," he said.

Gary blushed red. His mind flashed back to that afternoon when Bernie had caught him indulging his illicit passion.

He lay on his back on the padded back of the van, nude. He'd been daydreaming about his old girlfriend Sharon all day.

One evening at a beach party she looked at him and said, "Hey Gary, you're a pretty flexible guy, and you're the best-hung dude here. I bet you could suck your own cock." Sharon had urged him on, giggling drunkenly, until he agreed to try it. Gary had had a couple himself, so when Stuart, Kyle, and the other people around the fire had cheered him on, he stripped nude, lay on his back, curled up his legs, tilted them back over his head...and stared up at his cock, dangling an inch from his lips.

The people at the party cheered. "Go, Gary, Go, Gary," they chanted.

"Lemme start him off," Sharon said. She leaned in and took his cock into her mouth. Her beery breath tickled his nose, but he stiffened right away. She let him go and leaned back. "OK, dude, you're on!" she said. She took his cock in her hand and pointed it at his lips. Now it was long enough that he could take in the head.

It felt really good, but that night, Sharon had impatiently jumped on him and ridden him while the other people at the party cheered.

The day Bernie watched him, he had finally gotten comfortable enough to get himself off. It had taken a long time. She must have been watching him, curled up with his ass in the air, for quite a while.

His eyes focused again, and he looked at his girlfriend's mom, naked in the chair facing him.

Joyce smiled. "Maybe you can show me sometime. It would be a good motivation for Bernie and I to get serious about yoga."

Gary frowned. "Are you just teasing?" he asked. "You sound like you want to watch me suck my own cock and see me having sex with Bernie."
