It's...Lisa!

"God, I love watching you come, Steve," Suzi said, looking round the door.

I moaned as my cock pumped come through the wall into the tight ass I thought was Suzi's. "Who? Wha..?" I babbled. I tried to pull back, but my cock head was swollen up so I couldn't withdraw without yanking it out and maybe hurting whoever it was. As much as I felt tricked, I didn't need to be a dick about it. I closed my eyes and held on as my last spurts filled the end of the condom. After a minute, my erection subsided enough that I could slip out.

I stepped back from the hole in the wall and took a deep breath. "Suzi?" I asked, looking over at her. "Who?"

"Oh Steve," she said. "Don't look like that. This is a GOOD surprise!" I could see her busy little fingers scratching on the edge of the door she was holding.

"Good?" I asked.

"Come on round!" she said, waving me toward the door.

I walked suspiciously toward the door, but when I got to the other room, I took a deep breath and smiled.

"Sweetheart!" I said.

Lisa was leaning over the back of an overstuffed chair, her tight little butt next to the hole in the wall. She was nude below the waist, wearing only her silk-blend long underwear top. She smiled blearily at me, her loose hair hanging down over her face. I walked over, brushed back her auburn tresses and kissed her.

"Honey," I said, "I never thought you wanted to try it."

"Thought it was time I tried something sexy with you that was a little stretch," Lisa said. "It was pretty intense. It hurt a little. Not sure I like it. But maybe we can try again sometime. Maybe a finger or something would be about right."

"She liked my finger when I was getting her ready. She would have loved your cock even more, but she wouldn't let me do her clit," Suzi said. "You should try it with a vibe, Lisa. Just get Steve up your butt and don't let him move. It's fantastic!"

"I didn't want to try anything fancy," Lisa said. "I just wanted to know what it feels like. I think it's fancy enough, what we did!"

"Your wife really needs to take more responsibility for her own pleasure," Suzi said.

"Suzi!" I said. "Please chill."

"Okay," she said, and gave me her poor-cute-innocent-li'l-old-me face. "But YOU got off and left Lisa and me hanging!"

I looked at Lisa. Her cheeks were flushed, and she was breathing deeply. So was Suzi. Fair enough. But Suzi had run this show for long enough. I stripped off my spent condom into a handful of tissues.

I said, "I imagine you can take care of yourself, Suzi. Lisa honey, would you like me to help take care of your hot little clitty?"

"Please," said Lisa. She stood up and reached a hand toward mine.

I whispered an idea in Lisa's ear. She arched an eyebrow, then smiled and looked over at Suzi. "Suzi? While Steve is taking care of me, how about..."
