Sex within the family.

Gary finished reading Bernie's confession of sneaking off to watch him. Gary's just-spent cock twitched at the thought of his girlfriend watching through the window that day, pink-faced and shocked by seeing him having sex within his own family, but turned on. And forgiving.

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.

"It would hardly be unusual under our roof," Joyce said. "After all, you know Bernie and I masturbate together, and often family members come to Pleasure Circle together. You're welcome to come here. I'm sure it would be safer and more comfortable than a parked van."

Gary blushed red. "Um. 'Everyone' might not agree," he said.

His mind flashed back to that afternoon when Bernie had caught him indulging his incestuous passion.
