"I hope not so much that I'm in danger of losing you."
"Nah. I'm just saying...."
We had a drink in a bar downstairs, talking about the blowjob she had (unprecedentedly) given to a near-stranger the day before in his office, about my sordid past and, to a lesser extent, about just how we would each feel as my cock slid into her mouth, her cunt, later in the evening. "We should head upstairs," I said.
We rang the buzzer several times before I called. "Where are you?" he asked. I told him. "Oh, we moved the party." He gave me the address - twenty minutes or so from where we were - and told me to hurry. "We're getting ready to start."
We hopped in a cab and made our way there, past the doorman, up in the elevator, into the apartment, arriving moments before the festivities were to begin in earnest.
The host gave a short spiel on safety and etiquette, and invited us to get naked. I pushed L against a radiator, hiking her skirt up as I pressed into her. We ogled a few of the other guests - there were probably 25 or 30 there - but only one or two couples that looked genuinely appealing. It seemed likely to be an evening not of swapping, but just of hot sex between the two of us. This is a high-class problem.
I finished removing most of her clothes, leaving her wife-beater on. She looks so fucking hot with her little tits behind the sheer white cotton of a ribbed, thin wife-beater, her nipples straining against the flimsy fabric. I never wanted to take that shirt off. I removed my jeans and shirt, and, in my boxers, led her into one of the two bedrooms. There were two couples on the bed, in each of which the woman was sucking the guy off. There was another couple against the window in the corner, the guy fucking his girlfriend's face slowly, but insistently. She had an unbelievable ass, peeking out from beneath a cotton sundress as her head bobbed on his cock, guided by his hands.
"Against the window," I said, and I kneeled before her. L gave a deep, contented sigh as my mouth pressed against her, as my tongue found her clit. My rhythm was slower still than that of the woman to my right, having her face fucked by her muscular, tattooed partner, but L was responsive, pressing forward to meet me. After a while, I turned her around and placed her on the bed, below the two other couples, who were by now fucking. I sat her on the edge and guided her mouth down onto my cock, holding her back, only letting her taste the head. I guided her up and down, just an inch or so in either direction, maintaining her focus on the tip, for quite a while, until I was ready to force my whole cock deep inside her mouth.
Soon, I pushed her back, grabbed a condom, spread her legs in the air, and ground my cock into her, deeply, slowly. I gyrated my waist, pressing against her, but not moving in and out so much as around, and back and forth. Of course, I could take only so much of this before I turned her over and began pounding her in earnest from behind, alternately pulling her head back toward me by her hair and pressing her face down into the mattress. "Does she ever take her glasses off?" asked the guy next to us, who was trying to find a route in to our party, but not finding any.
After a few more minutes, we emerged from the bedroom, grabbing drinks and a bite, before heading into the other bedroom, where we did it all again. As a buff man stuffed the panties of his partner deep into her pussy (sorry, but not my thing), L sucked my cock, while I caressed the breasts and face of the woman in one of the two hot couples - a twenty-something blonde with preternaturally perky but large breasts.
Some more oral both ways, culminating in a shuddering orgasm by L, and then I guided her on top of me. Together, she and I shook the bed, now home to four couples in all, violently, as I bucked up and down, slid her back and forth. I shuddered and exploded, and we lay and debriefed, in whispers, while the panty-stuffer fucked the face and came on the tits of his partner. "Did you see him stuffing her panties into her?" I asked.
We got up, and went into the living room. Inspired by I'm not sure what, I bent her over against a kitchen wall and spanked her, first gently, then more firmly. "Use this," said our host, handing me a black lacquered wooden paddle. I did.
After a bit, our host exercised his prerogative (such as it was) and gave L a few whacks with his paddle. Having had quite enough, she collapsed next to me on the couch, where we did some last ogling before heading out.
Two days later, I awoke to an e-mail from L, subject line: "Holy crap." I scrolled down to see two pictures of her (perfect) ass, marred by lots of little bruises on one cheek, and a ginormous one on the other. "Turns out I have a reasonably high tolerance for pain, 'cause I don't bruise easily. What happened to no marks?!"
