It's...Jeri!

"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. I grabbed a wad of tissues from my jacket pocket and disposed of the spent rubber before going further.

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

I followed her suspiciously, but before I could get to the door I was seized by someone coming from the other side. A pair of long female arms wrapped round me, a pair of big soft tits pressed my chest, and pair of warm lips were kissing mine. "Mmmm--smack! Bravo, Steve! You're a real backdoor cowboy!"

"Jeri?" I said. My cock stirred, alive again right away.

"None other," the tall blonde said, rolling her shoulders to slide her tits round my chest. "Lisa told me about your trip, and Tom and I decided we'd get one last day out of our season tickets. I managed to get Suzi to spill the beans on what she had planned, and decided we could get a jumpstart on tomorrow night's party!"

"So what are your plans for tonight, if you came all the way out here?" I asked Jeri. And where were Chuck, Tom, and Lisa, I wondered. I tried to look over Jeri's shoulder into the next room.

"I don't think Jeri has plans past her next orgasm," Suzi said. She gave a little toss of her head, shaking her blonde pageboy. "She hadn't quite made her O when you unloaded in her butt, Steve, and if she had pants on, they'd be on fire."

"Brat!" Jeri said. "As a matter of fact, I..."
