Her muffled screams were exciting to hear, but not nearly as exciting as the feel of her frantic cunt on me or her heaving tits in my appreciative hands. I thrust up to meet her downstrokes, ramming her hungry twat as hard as I dared. Mark had his hands on her shoulders and he was swaying his hips back and forth, carefully pumping her mouth.
Kate suddenly pulled her mouth off her husband's throbbing dick. "Don't – don't – don't you dare cum y-y-yet! Either of y-y-you!"
Then her face tightened and she looked ready to scream. Mark rammed her face onto his cock just in time and she gurgled and shook tautly.
She started to lose her strength then, and was beginning to sag down onto me. Mark's dick popped out of her mouth and I lowered her torso to my chest as he carefully climbed off the bed. Her hips rolled and her cunt moved on my cock as she nestled against me. I continued carefully thrusting until I felt her tensing again, then held her mouth against my chest to muffle her scream. Her teeth pressed against me as she howled.
When she eased off, she mumbled, "Both of you…like we saw…in front and back…please?"
Mark was again standing at the foot of the bed, stroking his cock and watching. He didn't hear her clearly.
"She wants you in her butt," I explained.
"She almost never wants that," he protested.
"You want to argue or fuck? Night-table drawer – open it."
Kate was bouncing her hips up and down on me again, her mouth against my chest. I had my hands on her rich, round ass, squeezing it and enjoying the play of those firm muscles under my fingers as she quickened her ride. Just as she started to cum again, I pressed a fingertip against the rubbery rectal opening and she tightened immensely on me. Piss-hard or not, I wasn't going to last long if she kept doing that. Some of her orgasmic scream almost escaped the muffling and she bit into my chest to stifle the volume. Also stifled the rising cum in my nuts.
Then the bed shifted as Mark crawled up, feet outside my knees. His dick was completely coated and throbbing like a teenager's above his wife's beautiful ass. I separated the cheeks of her ass and held her tightly down against me. Mark lined up his dick and I felt her tense and shiver as he pressed it against her ass.
Her cunt clenched feverishly around my prick as his dick started to spread her sphincters. When his glans finally popped inside her ass, she made a funny noise, growling like a woods animal. Mark pressed the rest of his cock into her and the sensation of tightness spreading slowly up her cunt and over my cock was unbelievable. His balls finally swung against the base of my dick and her cunt and Kate lay stock-still, as if paralyzed.
"I feel so fucking stuffed," Kate mumbled. Mark bent close and kissed her ear and the side of her face. "Oh, honey," she whispered, "I love you so much…both of you. Oh!"
The "oh" was because Mark had just twitched his dick a little bit deeper into her.
"Unnnnnnnn…" she groaned as he pulled back about halfway, then slid slowly back into her. She kept making that same, low noise as he speeded his pumping. I lay motionless, savoring the marvelous sensation of his dick rubbing mine through the thin membrane separating her stretched asshole from her stuffed cunt.
"C'mon, fuck me, fuck me!" she hissed at me, raising herself onto her elbows. I tried moving a little inside her while Mark lengthened and speeded his strokes behind her.
"Yeah!" she hissed as her husband pounded her ass and I hunched my cock in and out of her, sometimes simultaneous with his sodomy, sometimes syncopated. Kate's lovely face was bright red and contorted as she growled and moaned. "Harder! Fuck me harder, damn you! I want you to pound me!"
"Bad pun," I gasped.
She took my hair in one hand and mashed her lips against mine. She sucked my tongue into her mouth and treated it the way she'd treated my dick. I held her ass in my hands, Mark's abdomen hitting my fingers when he slammed down. I pumped her hips up and down in time with my urgent thrusts up at her, letting Mark fend for himself. He was doing just fine, lowering himself till his weight was on his wife's back (and me) and he thrust all the way into her at the same moment I did.
Kate screamed into my mouth as she felt her husband's cock swell and twitch and then fire its load deep into her ass. Her cunt cranked down on my cock so hard that any thoughts I'd had about cumming were finished for the moment; it was just too tight, like a cock ring, for me to unload. That was a first for me, too.
Kate's orgasm was every bit as awe-inspiring as I'd imagined. She just kept cumming and cumming, her entire body rigid and taut as a violin string. She barely shuddered, barely moved, for the longest time. It was like a seizure of some kind.
Mark was climbing thoughtfully off us, slowly pulling his shrinking prick out of her ass. When his glans came out of her constricted anus, it made a loud sucking noise. Then Kate shook and sucked in a long, noisy, rasping breath. She was shivering uncontrollably. She finally sagged and went limp as a wet cloth.
I rolled us over, staying inside her. Her legs fell open and I pumped her furiously for a few seconds, trying to relieve the ache in my nuts. She came a few times, even as she lapsed into unconsciousness; I felt it on my cock and saw it in the way her tummy convulsed and her abdomen hardened. But I was past the time of cumming easily and tiring fast…and I had to piss in the worst way.
I pulled out of her slowly. I bent to kiss her hard nipples and, lightly, her lips. Even dozing, she whispered, "I love you, Mark." I climbed off the bed, stood and groaned. Mark was staring at his wife and my cock.
"Okay, you got what you wanted, she got what she wanted – now cuddle your honey."
He nodded and moved mechanically toward her. I stepped out of my bedroom just as she nuzzled up to him and made a soft, happy sound. I envied him her love and – even more, now – her lust.
On bowed legs, I stepped into the bathroom and waited long minutes for my cock to deflate enough to begin voiding my bladder. When at long last it was done, I was still left with aching nuts. I showered quickly, brushed my teeth, pulled on my robe and went downstairs in search of food. I had just burned a lot of calories and my stomach was growling. I grabbed a breadstick from the Stella Dora package in the refrigerator and munched it as I refilled and started the coffeemaker. Then I decided to check on my other guests.
Penny's bed was made and she was nowhere in sight. When I looked out into the yard, though, I saw her curled up on a chaise lounge by the pool, devouring one of my books. Fine.
Then I decided to look into the other bedroom, the one assigned to Irene and Bonnie, the one where Dolores had been stashed after her "rescue" the previous night. I opened the door quietly and looked inside.
Irene and Bonnie were still clothed and still sleeping, wrapped sweetly in each other's arms in one bed.
In the other, Dolores sat with her back against the headboard, looking from the bi-lovers to the doorway. She was naked and she had her hands between her legs. Busy little fingers.
"I heard what was going on upstairs," she said. "I went up and watched for a while." Her whisper was barely audible. "I came downstairs and washed up." She pulled her knees back and up, almost to her quivering young breasts. "I've been waiting for you."
I started to back out of the doorway, the door knob in my hand, but Bonnie raised her head and grinned. "Come on, Uncle Dan – it's inevitable. Surrender."
My dick was already giving the lie to any protests I might have made and the robe wasn't concealing it at all.
I stepped into the room, closed – and locked – the door and surrendered to the inevitable.
