Maybe double vaginal?

"Well, hey," Billy said, looking into Veevee's eyes, face to face. "It feels really nice having you sit there on me. He tensed his P-C muscle, making his cock twitch and swell.

Veevee cooed. "No end of tricks in you," she said.

"You still comfy there, sitting on my cock?" Billy asked.

"Well, as long as you don't expect me to do anything, I'm very comfy," Veevee said.

Billy laughed. "You are a sweet darling," he said. He looked to the side. "Isn't she, Hank?"

Hank said, "I would never argue with that."

"Oh, you," Veevee said.

"Little early for you to be fucked out, honey?" Hank said.

Veevee leaned forward and put her head on Billy's shoulder. "I don't know what he did, but when I came, it practically blew the top of my head off."

"That's the way it's supposed to work," Billy said. "Though I've always practiced it sitting down."

"Hmm," Hank said. "Mind if I take a closer look?" He gestured to where Billy Royce's cock, still hard, with balls twitching whenever he tightened his muscle.

"Be my guest," Billy said. "It's sweet how you care for Veevee's joy."

"Oh, she cares for mine, too," Hank said.

He bent down in front of the couch, his head close to where the rock star's cock penetrated his wife's pussy. Billy's heavy balls were nestled under Veevee's pussy, and his cock root traced down, a little seam running down the center, till it connected to his body where the folds of his buttocks started. Hank breathed in the grassy sweetness of Billy's pre-cum and the sexy musk of Veevee's pussy, oozing juice after her "flying" orgasm with Billy.

"You'e got some nice balls, Billy," Hank said. "Big and heavy."

Billy laughed. "Like 'em? Go ahead."

Hank stretched a little forward and sucked in one of Billy's balls, caressing the other with his fingertips.

Billy made a low, growling sigh. "That's the way, Hank," he said. "Real good."

"Oh, honey!" Veevee said, her voice rising with excitement. She tensed her legs and rose up, then descended.

"I love this," Billy said. Veevee was riding his cock again, gently, sliding that sweet pussy up and down his shaft, while Hank worked Billy's balls with fingers and mouth. "The both of you."

"Our pleasure," Veevee said. "Our pleasure. You ever make it with more than two people at a time?"

"Ahhhh," Billy sighed. "Yeah. Three."

Veevee laughed as she kept riding Billy. "Three? Stick around, we can beat that easy. Jim and Sally would totally be up for it."

"Ah, hah, ahh," Billy said. "Ask me later. Oh wow!"

Veevee felt her entrance stretch. Hank slid his fingers up Billy's hard shaft and into Veevee's wet pussy.

"Damn, that's a new one," Billy said. Hank was playing with Billy's balls with one hand and sliding two fingers up and down Billy's shaft at the entrance of Veevee's pussy.

"If you're up for something wild," Hank said. "I'd love to join you inside Vee."

"Oh, I'd love that," Veevee said. "Two lovely cocks in my pussy. But you're our guest, Billy. Whatever you like is fine."
