Joyce watches Bernie and Gary masturbate and finger each other.

Joyce had made it clear that standing outside and looking through the window would be uncomfortable, so instead of standing outside and looking through the Super Surf Van's window curtains like Bernie had when she had caught Gary and his mother in the act of masturbating together, Joyce was sitting up front in Stuart's swivel seat.

"What did your mom say next?" Bernie asked Gary. "After she said she was going to let you see her come?"

"Mom wanted me to do the same thing she did to me the night before, when she jacked me off after we talked about me and Peter," Gary said. "Put a finger up her butt."

"I want us to do the same thing, Gary," Bernie said. "You and me. And sometime I hope your mom can come over and all of us, you and me and my mom and yours, can see each other come that way."

Gary nodded. "Mm-hm," he said.

"Or if you're okay with it, maybe Lil," Bernie said.

Gary gulped. "Maybe."

Joyce smiled. Gary's sister Lillian had found out that Joyce was the author of her favorite school text, Free to Masturbate. After Lillian came back from shopping with Naomi, she and Joyce had closeted themselves together for some advanced study around Lillian's favorite chapter, Advanced Female Masturbation Techniques, while Gary and her daughter were mending fences around the sexual boundaries of their relationship. Lillian was a charming, very orgasmic young woman, and their first sexual encounter in the shower, after a swim, had gone very well. Lillian had been back for several repeat lessons, and showed strong potential for becoming an anal-erotic enthusiast like Joyce and her daughter -- or, for a fact, one like Lillian and Gary's mother Veevee.

"Reach me the lube," Bernie said. "The other one," she clarified, pointing for Gary. She adjusted the cushions behind her and lubricated the fingertips of her do-myself hand. "How close were you sitting?"

Gary said, "Pretty close, so we could reach each other, you know, with the other hand?" He adjusted his own towel and cushion. "I think you have to open your legs a little more and maybe pull your knees up?"

"Tell me everything your mother said when you were in the van together," Bernie said. "Everything you did, anything I couldn't see."

Joyce watched quietly from the swivel seat, openly masturbating as she watched Gary lead Bernie through the details of the scene she'd caught Gary in, masturbating with his mother. Bernie was sitting right where Veevee had been, and Gary was sitting where' he'd been that day, with the same towels and bottles of lube. She sighed when Gary's finger penetrated Naomi's anus, and again when Naomi, Bernie rather, when she returned the penetration for Gary just like Gary's mother had done on that day. Her lovely daughter. Her daughter's sexy boyfriend. She loved watching Gary's cock swell and stiffen. It was quite the treat. He still had that bewildered look that young men sometimes got around sexuality, for all the frequent experience that Gary had had with women of his own age, several more mature women, and numerous young men including his best friend Peter, plus the somewhat older male partner, Stuart, a Pied Piper of pansexual play parties and the owner of this very rolling orgy studio pretending to be a mattress-backed surfing van.

It seemed to Joyce that it took a little longer than the original scene, as Gary and Naomi had described it, to get comfortable, but of course her daughter had walked up on the scene well in progress, with Gary and his mother already masturbating, each with a finger in their partner's anus, a scene which had shocked and aroused her daughter, because it was so close to what Naomi and Joyce did with each other, especially between when her daughter had lost her lover Habiba and when she had taken up with Gary.

Joyce was pleased that Gary was moving carefully, listening well to his partner's directions, while telling the story of how eager his mother had been on that day, just as her daughter had asked. Tell me everything.

Joyce rubbed her clit faster as she watched her daughter's expression soften and go distant, with Gary's slick finger stabbing in and out of her anus. Then her daughter's eyes opened wide and she squirted as her orgasm took hold. My darling girl, yes. Gary's fist stroked faster up and down, the tip weeping fluid. Bernie's legs kicked. Her head strained down and bucked upward. Her extended finger plunged deep into Gary's anus. Gary's chin lifted. He closed his eyes and parted his lips. His ejaculation spurted high to land on his chest, and Joyce let her own orgasm take her with her pleasure boosted to supreme heights by watching the young couple's mutual climax.

Joyce was first to recover her senses, and she left her seat to join her daughter and Gary in the mattress-padded back of the Super Surf Van.

"My lovely young ones," she said, cuddling them close to her on each side. "That was so beautiful to see."

They lay together, floating on the afterglow of climax, Bernie and Gary on their sides with a cheek resting on Joyce's chest.
