It was barely five minutes before her legs were spasmodically clenching around my hips as I pumped my load into her, both of us shouting, grunting, gasping. After another five minutes or so to catch my breath, I was getting ready to leave. Kate was still lying on her back on my desk, her hand between her legs, languidly playing with the cum dribbling out of her cunt. When I hesitated, looking down at her, she said, "You'd better go on home to Annie. I hope you have some left for her." She looked at the crotch of my pants, about eye level with her. "I'm sure you do." She smiled sleepily. Before leaving, I stopped in the men's room to wash myself off as best I could with paper towels and hand soap. Given the mood Annie was in, it seemed likely that she'd have her mouth around my cock within seconds of me walking in the door, so I figured it would be a good idea if that cock wasn't slathered with a mixture of my cum and Kate's pussy juices. But as it turned out, things got interesting again before I even got home. When I went down to the office building's underground parking lot, Annie was there, leaning against my car and waiting for me.

"Christ, it took you long enough," she complained as I approached. "Well, I had to wait for Kate to leave the office for a minute so I could put my dick away and zip my pants." As I spoke I saw that Annie's coat was unbuttoned and hanging open. "Fuck you look good, honey," I said. "Have you just been standing around showing yourself off to passers by?" "There haven't been any passers by, lucky for me. I've been standing here playing with myself, keeping my pussy nice and wet for you." She reached a hand down to her cunt and slid her fingers up between the lips, then drawing them away and holding them up for me to see. Even in the gray light of the parking garage I could see the glistening, slick wetness on her fingertips. "See?" I answered her by pulling her to me for a passionate kiss, dropping one hand down between out bodies to cup her pussy. She whimpered into my mouth, putting her own hand over mine and pressing. I slid two fingers into her, and she gasped out an "Oh!" that echoed in the cavernous garage.

"Fuck me, goddamn it," she ordered, fumbling to get my fly open. My cock was recovering quickly from my orgasm of a few minutes ago, but it wasn't the full-tilt boner that my wife had every reason to expect from me. So to give myself a little more recuperation time I dropped to my knees and buried my face between Annie's legs. She was standing at the side of the hood of my car, so she could rest her ass against the front fender. She leaned back, bracing her arms behind her on the hood and spreading her knees for me. I pressed in, pushing my mouth up to her warm, wet pussy and thrusting my tongue out to lap at her clit. With soft moans and whimpers, Annie expressed her appreciation of my efforts. She put one hand on the back of my head and pulled me in snuggly against her pussy, and we stayed like that for a while, my tongue busily flicking and lapping over her clit and slithering inside her from time to time. Then Annie decided she wanted us to switch off.

She tugged at my arms to get me to a standing position and then slid down off the hood of the car, kneeling at my feet. Then it was my turn to tip my head back and moan appreciatively, as I felt her warm mouth close around my cock. There was a frenzied quickness to Annie's sucking motions that told me she wasn't settling in for a nice leisurely blowjob. She just wanted to give me a quick suck to make sure I was good and stiff and ready to plow the furrow of her pussy. I was indeed as stiff as the proverbial board with rigor mortis, and Annie was just about to pop me out of her mouth and stand up, when...

A car horn went off about twenty feet away from us. It was just two quick honks, but coming unexpectedly in the closed, quiet space of the parking garage the sound was like a smack in the face. Annie jerked her head away from my cock, and in the process banged the back of her head against the side of my car. I snapped my head up, looking for the source of that honk. It was Kate, on her way out of the garage in her VW. The road out of the lot put her car parallel with mine, with my car between us. This meant that she couldn't see Annie, still squatting at my feet.

Kate came to a stop and rolled down her window. "Hey David," she called. "What are you still doing here? Car trouble?" I went into a silent panic. If Kate said anything incriminating, not knowing that my wife was crouching at my feet and could hear her... "Just a problem with my side mirror here," I said. Then I gestured urgently, pointing down not at the mirror, but toward where Annie was. "ANNIE" I mouthed silently after glancing down to make sure Annie wasn't looking up at me at that moment. It must have looked to Kate like I was pointing at my crotch and working my mouth like a fish out of water, but somehow she understood what I was trying to get across. She nodded, mouthed "Ohhhh," and gave me that same wry, taunting smile she'd shown when she was peeping at Annie and me in the office. This is fucking deja vu all over again, I thought.

"Your mirror, huh?" Kate said, her smile growing into a mischievous grin. "That's too bad." She was shifting forward in her seat and doing something with her jacket that I didn't understand at first. Then her left tit appeared, plump and pink and held up for me to see in her hand. I remembered that her blouse didn't have any buttons left on it, thanks to me. "Say David," she said in a conversational tone. "Has the copier been working okay for you lately? When I tried to use it today..." and she went on to talk about cryptic copy machine error messages, paper trays, toner cartridges and so on, all the while displaying that tit to me, bouncing it in her hand, squeezing it, running a finger over the nipple.

The joy that this woman seemed to take in teasing me was positively sinful. Down at my feet, Annie suddenly took hold of my lower leg with both hands and shook me. Not hard enough so that it would show from Kate's vantage point, but enough to convey her message: Get rid of her! Luckily, after a final, extravagant squeeze of her nipple, Kate chose that moment to put her boob away, say good-bye to me, and drive off. Annie climbed to her feet, glaring in the direction of Kate's departed car and rubbing the back of her head. "If that woman cunt-blocks me one more time," she said, "I swear I will kill her with my bare hands." "She's gone now," I said soothingly. "Now where were we?" Naturally, my cock hadn't lost any of its stiffness during Kate's interruption. I pulled Annie to me, reaching down for her pussy.

"Agh, I'm not in the mood any more," Annie grumbled, twisting away from me. "I'll see you at home." She walked off to where her own car was parked, banging her heels on the concrete. Happily, by the time we got home she was in the mood again. She parked behind me and hopped out of her car, her coat unbuttoned and blowing back from her magnificent body in the breeze. "C'mon stud-boy," she said taking my hand and pulling me toward our door. "You owe me a good one." I guess I do at that, I thought. I knew that every time I cheated on Annie by fucking Kate, I was going to feel like I owed something to Annie. But as long as I'm able to make the payments... End
