Oops, wrong hole!

Zack settled down on the bed behind Hannah's buttocks, straddling Gavin's knees. His blood singing in his ears, he grasped his cock and pointed the head to the pink halo of Hannah's butthole, then pressed forward eagerly. His cock tip slipped but plunged in. It was tight and hot and...what?

Zack's cock slid along a lube-slippery latex-clad rib and prodded a firm little bump.

Gavin's cock head. Zack felt his friend's shaft swell up against his.

"Zack," Hannah said. "That's not where you're supposed to be."

"Wow, what?" Gavin said.

"Um, sorry," Zack said. His cock pulsed, swelling up against Gavin's. "I missed. Uh, should I...?"

"It actually feels good," Hannah said. "Are you boys...are you boys good with it?" She looked down at Gavin, who looked as dazed as he had since he'd discovered Hannah and Zack under his bed, and round at Zack. Zack's eyes were wide open.

"Okay, nobody go anywhere," Hannah said. She got a sly look on her face. "Everybody stay where they are."

Gavin nodded. He was underneath both of them, anyway.

"Um, okay," Zack said.

"Gonna try something," Hannah said.

Hannah took a couple of deep breaths. She narrowed her eyes and squeezed.

"OH!" Zack and Gavin said, feeling Hannah tighten round them, squeezing their cocks together.

Hannah laughed. "Oooh, that's working," she said. "Don't go anywhere."

"OH!" Zack and Gavin cried out again.

Hannah got into a rhythm, squeezing and releasing, squeezing and releasing. Her face and chest flushed pink and her nipples swelled into hard, erect points. The three of them cried out together with each tight squeeze of Hannah's cunt.

Hannah paused, her breath coming in ragged gasps. "Oh. Kay. That works. Kinda tires me out. Zack, start moving."

"Uh?" Zack said.

"Zachary Bishop," Hannah said. "Boy? Fuck. My. Fucking. Cunt." she insisted.

Zack's cock swelled again, and Gavin's swelled up against his.

"You, uh, okay, Gav?" Zack asked. "I mean, like, for your first time?"
