Gary wakes at dusk with Joyce grinding on his butt

Gary napped away the warm afternoon, Behind Gary, Joyce was cuddled up with her soft curves to his back and buttocks, and Bernie was facing him, her curly hair tickling his face and her soft breaths on his neck and shoulder. His cock hardened against Bernie's belly, then softened as he drifted back toward sleep.

Gary woke to a rhythmic pressure on one buttock. Pressure and weight. He was sprawled with his chest down against the mattress, his legs parted, and a warm, firm pressure on his butt, pressing down and rocking back and forth. Kinda nice, like a massage. A body on body massage.

Except the rhythm was speeding up and the pressure was getting heavier. Gary wondered for a moment what was up.

Then Joyce started moaning in rhythm with each rocking movement and Gary felt the squish of her wet pussy lips on his right buttock.

Gary opened his eyes. Bernie was still lying next to him. It was dim in the room, after sunset. Bernie was looking up and over Gary's shoulder, smiling at her mom as Joyce humped her boyfriend, grinding on Gary's butt like a warm, firm pillow.

Gary knew Bernie liked to get off like that sometimes, grinding on a pillow. Her mom must like the same, but today Joyce was using Gary for her masturbation pillow. Joyce's pussy lips squished audibly against his butt as she ground down harder and faster. Her soft moans got louder with more breath, moaning and panting at the same time. She was going for it. Gary's cock hardened against the floor mattress.

Joyce's rhythm got uneven and jerky. Her moans got ragged. She called out loudly and let herself crumple forward, resting her belly and breasts on Gary's back as her hips pumped, grinding out her orgasm into Gary's butt. She held tightly to Gary's upper arms, holding him in place as her body rocked with spasms of pleasure.

Joyce sighed and relaxed, settling down with her full weight on Gary's back. "That was delicious," she said.

"You look so happy, Mother," Bernie said.

"I am, darling. Thank you for sharing him with me." Joyce lifted a hand from Gary's shoulder and stroked her fingers through his blond hair. "Darling young man, let me know if there's anything I can do to make you feel good while I still have you."

Joyce's warm, soft weight pressed down on Gary. He wasn't going anywhere if she hung on tight.

Gary chuckled. "Dunno. I liked how you got off on me, Joyce. It got me hard again. Maybe Bernie wants to try waking me up like that sometime."

"I suppose I could give you back now, hmm?" Joyce said. She nuzzled Gary's ear and murmured in a low voice, "Some day, Gary. Some day I want to strap it on and fuck you. Fuck-fuck-fuck you. If you're game. If Naomi, if... If Bernie is okay with that."

Bernie smiled. "I heard that, Mother. Yes, I'm okay with you strapping it on for Gary. As long as I'm there."

"Gotta think about it," Gary said. It didn't feel any crazier than anything that had happened the last couple days. His cock didn't go limp, which was half a vote, maybe. Maybe not now, not this evening.
