Bernie is going into Peter

Bernie knelt behind Peter on her bed. She cupped his buttocks and gave them a gentle squeeze. "How's it feel now?" she asked.

"Starting to feel really good," Peter said. He held himself up on hands and knees in front of her on a towel spread out on her bed.

Gary watched from the side as his girlfriend, hips wrapped up in a harness, held still behind Peter and let him get used to the anal penetration. Peter's penis, which had softened and sagged as Bernie had carefully worked the dildo up inside him, was pulsing and starting to firm up again. Gary's cock twitched, remembering the feel of Peter's ass on his cock, and twitched again, remembering how Bernie's dildo felt inside him.

"You can start moving," Peter said.

Bernie laughed. "Okay, here goes," she said. She looked round at Gary and smiled, then mouthed a silent Thank you. Gary grinned and nodded.

Bernie started rocking her pelvis gently, thrusting the harnessed dildo in and out of Peter's ass. The soft curves of her belly, buttocks, and breasts bounced with her motions. Bernie's mop of brown curly hair was tied up atop her head in a braided twist her mother had fixed up for her.

"Mm, you're liking this," Bernie said, keeping up her steady, shallow thrusts. "Does Sandy do this for you?"

"Not. Much," Peter said. "Doesn't do much. For her. Her big sister Peggy. Really likes it."

"Did Peggy make you come?" Bernie asked.

"Yes," Peter said.

"Do you think you can come for me?" Bernie asked.

"Yes. I want to come for you," Peter said.

Bernie grinned. It felt powerful being behind this beautiful young man, Gary's friend, giving Peter what Gary had secretly given him for two years, holding the buttocks that Gary had held, pleasuring Peter with her thrusts like Gary had.

Bernie laughed. "Gary, I'm fucking your boyfriend," she said. "I'm going to make him come."

Gary laughed. "You're the best, Bernie," he said. He smiled and shook his head, at a loss for words. "Yeah."

Gary watched as Bernie gave Peter a slow, steady fuck from behind, her golden skin moving against his pink, his long, slim cock bouncing gently with her thrusts.

Peter's breaths went from sighs to moans. A bead of clear liquid formed on his cock tip and fell, descending on a glistening thread. "Faster," he said.

Bernie picked up her rhythm, making longer, faster thrusts.

"Gonna..." Peter said. "Bernie? Oh!" Peter darted one hand back to grip his cock. Two quick strokes and his cock swelled, twitched, and shot hot cream onto the towel.

Bernie eased off her thrusts into stillness.

"That was beautiful," she said. She looked round at Gary.

"Yeah," he said. He nodded and smiled at Bernie.
