It was my fiftieth birthday, and my wife had rented a small lounge/restaurant for a party. The invitees were employees and agents of our real estate company. My wife was the owner/broker and never missed an opportunity for a team-building exercise, even if it meant co-opting my special day. I hadn’t realized it yet, but she was a real control freak with an unrealistic (and ultimately self-fulfilling) belief that I was screwing around on her.
The restaurant was a somewhat upscale Italian-themed place with delicious food and drinks, all for reasonable prices. We had rented the place a few times before and the owner had always given us “bulk” pricing, which we greatly appreciated. The owner was a divorced woman who looked delicious in her own right.
It was about 9 PM, everyone had arrived, and the closed sign was on the door, which remained unlocked for fire safety purposes. There had been a few rounds of drinks, mostly the establishment’s signature mimosas, and the food was being served. I had heard some loud motorcycle sounds outside, but we were so close to a major urban artery, and I didn’t give them a second thought. Then the door burst open and nearly twenty of the Dirty Dozen gang stormed in. The first one went to the hostess podium and ripped the phone cord from the wall. Another went to the cash register at the end of the bar and did the same. A third went into the back, presumably searching for more phones to disconnect. The last two took up guard positions at the door looking quite impenetrable.
A few of our people made various sounds, but my wife went into attack mode. “How dare you? Who do you think you are? You are not invited. Leave immediately!” As she addressed the interlopers in the top of her voice, she was moving rapidly and threateningly toward the closest one. I’ve seen this woman, armed with only a ballpoint pen, go after a large surveyor wielding a chain saw as she intended to defend a tree. Turned out, he was only lopping off the top few inches of a fence post so his transit could see over it. She could be stupidly fearless.
He was over twice her size, both in height and bulk. When she was just inches from him, looking pretty much straight up, they glared at each other for a few moments. Then he grabbed her shoulders, spun her around as he leaned over, grabbed her right tit with his left hand, and reached under her dress with his right. “For a loud-mouthed bitch, you got an okay body. We’re gonna have some fun, cunt.” That brought gasps and protests from our guests, but I noticed nobody moved.
Two of the bikers moved toward Anna, a small, Puerto Rican of mid-30s, single mom. She had a cute face and body, small tits, but no noticeable belly swell from carrying her son who was now in his early teens. “You kinda small. Think you can handle us both at once?” Anna’s naturally darkish skin seemed to pale under the glare of their sneers. She’d always had a “party girl gone straight” air about her and I wondered just how hot her Latina blood ran.
Janet, another agent, moved to Anna’s side, but that only served to attract the attention of three more bikers who moved to surround her from the rear. Janet was early forties, bleached blonde, voluptuous but sagging body that had seen too much sun, covered in clothing meant to teasingly reveal her ample assets while hiding other areas which were a little too ample for an aging woman still desperately clinging to her twenties. The man behind her reached around and hefted a breast in each hand, lifting and kneading them through the cloths of blouse and bra. “I’m looking forward to fucking these,” he laughed. Janet tried to squirm away, but the other two men each grabbed an arm. The one behind her continued, “Yeah, bitch, I’m going to titty-fuck you and cum in your mouth. I bet you swallow, don’t you?” Janet shook her head back and forth, making negative sounds. My impression of her was that she was probably more show than go. Not that she was a prude, like my wife, but I never got the sense that she had an adventurous libido. It was more that she was trying to attract a mate with her plumage.
Pamela, the oldest woman agent there and former owner of the office, was a trophy wife of a much older and very wealth man who she’d married for his money. She was in her mid-sixties, also clinging to her younger years, and also dressed revealingly. She had once had a dynamite body, and what remained was still fine to look at. I had a sense that she’d be willing and eager to do whatever was required to achieve her goal.
Meanwhile, my wife, Brenda, was standing frozen in mortification as the biker crushed her right tit in his left hand while the hand under her skirt was moving like he was finger-fucking her. Oh, my poor, old-school Christian-inhibited wife. I had a strong idea of what was going on in her head. She was a weird mix of inhibitions and repressed sexuality. She loved me going down on her and loved her ass being fingered and fucked, but otherwise, it was straight missionary. She wouldn’t even kiss me after I’d gotten her off with my mouth and my facial hair was drenched in her wetness. Personally, I loved her flavor and scent and feel. Sometimes, I’d push her beyond her limits, giving her samples of herself which she reluctantly tolerated. A couple of times, I wet my dick in her, then had her suck it clean. Oh, she hated it, so she seemed. But whenever I’d push her, she’d ultimately climax much harder and longer than when we remained within her boundaries. She had deeply repressed kinks that she enjoyed but refused to admit. I suspected that the biker’s fingers were getting drenched.
The biker who went into the back room returned with the restaurant’s owner, Helen. Like Janet, she was mid-forties but was childless and had not spent so much time in the sun, so her skin was much younger appearing. She was about Janet’s height, too, around 5’8” with large breasts, narrow waist, and flaring hips. Unlike Janet, she dressed to accent but not display. Everything properly and tastefully covered, yet under tight enough clothing to show shapes and curves. Right now, those curves were tucked, kicking and screaming, under the right arm of a hefty biker not much bigger than her.
Following him were three more bikers herding the restaurant crew ahead of them. Cook, busboy, and dishwasher, all Mexican men. “Fuck!” the head of the gang swore when he saw them. His expression said he was considering ending them, just to reduce the witness count. That didn’t bode well for any of us. “Motherfucking, goddamnit!” He stood there staring over them into the mirror behind the bar, thinking. “Toofee, Candyass, get some shit to tie these fuckers up and someway to blindfold them so I don’t have to poke their eyes out.” The Mexicans cringed at that. Well, they understood English and the biker boss noted with a loud sigh. They should not have reacted at all. The two guys came back with zip ties and dirty t-shirts which they used to bind, blindfold and gag the three.
The two men with Anna were removing her dress in a surprisingly gentle manner. She stood there, limply complying, head down, making no moves to hide herself as they proceeded. It was an odd sight and I wondered if, before coming to the States, she’d been in this position before. A pervy part of me was looking forward to watching these various women, hopefully naked, being used and abused by men with no inhibitions. My thoughts briefly touched on joining in. It had been years since I’d had real fun during sex. Best not get up expectations.
As the man behind her removed her bra, the one in front knelt to slide her panties down. She voluntarily lifted one foot, then the other, so he could fully remove them. She stood there, arms down at her sides, pert B-cup breasts with dark chocolate areolas and distended nipples, and a dark brown bush hiding most of her slit, although clit and inner labia peeked through. I wondered if she was wet. As the man behind massaged her breasts, pinching and pulling her nipples, the kneeling one pressed outwardly on the insides of her knees. She complied by moving her feet about two feet apart, opening access to her nether regions. His fingers slipping easily into her brought a stiffening to her body along with an audible intake of breath. My question was answered when they emerged glistening in her juices. I glanced around; everyone was fixed on the performance, including Helen who still dangled under the biker’s right arm. The Mexicans were doing their best to disappear where they sat.
The kneeling biker slipped the wet fingers into his mouth, sucking her juices from them. “Mmm, mmm, mmm mmm, mmm!” he exclaimed. “Ain’t nothin finer than brown pussy.”
“You want her pussy, Nick?” the other asked. “I’ll take her ass.”
“Hell, that works for me,” Nick agreed. He was unfastening his jeans as he stood. The other released her tits to drop his own jeans.
Nick lay on his back on the floor, his rigid dick twitching over his belly. He pushed it up vertically. Fuck, it was at least 8 inches long and two inches in diameter. “Straddle me, bitch.” Completely submissively, without expression, Anna knelt over his waiting erection, then sank down onto it, burying it fully in her. The whole thing without a flinch on her part. “Holy shit, woman. Ain’t no woman ever taken me like that. Now fuck me like your life depended on it.” Anna began working her hips, grinding herself on his groin. I wondered what that flashlight of a dick felt like rocking back and forth inside her. Squishy sounds were coming from their joining.
The other biker was standing at Nick’s feet, stroking his dick. He wasn’t as long but was another inch in girth. I wondered how that was going to fit in her rectum. He grabbed some butter from a breadbasket. My mind flashed back to the rape scene in “Las Tango in Paris.” He nudged Nick’s legs apart, then knelt between them. With his hand between her shoulder blades, he pushed Anna down against Nick’s chest, opening her ass to his penetration. Lubing his dick and her asshole with the butter, he first probed into her with one, then two, then three fingers. The latter drew a whimper from her audible over the squishing of Nick’s dick pumping in and out of her cunt. “Come on, Rash, stick it in her. I want to hear her squeal when her ass rips open.” Another whimper from her. I wondered how much was from the prospect of her ass being damaged and how much was from the name of the man who would do it.
Rash moved forward, spreading her ass cheeks wide, stretching her anus open. He positioned the head of his cock against the tiny brown opening. It looked like a fist against a hole the size of a dime. He slowly pressed forward. Anna went rigid, hands balling into fists against the floor on either side of Nick. It was the first response; other than the two whimpers she’d made. Pressure won and the anus gave in to the onslaught. Her body spasmed as the three-inch head slipped inside a hole too small for it. A sharp cry escaped her throat. “Goddamn, she’s tight,” Rash gasped. “I think it hurts me as much as her.”
“I hope not,” Nick replied. “I can feel that monster. Her pussy is going wild.” Rash pushed another inch in and Anna cried out again. I could hear other women gasping; one was sobbing. I couldn’t look away. My dick was hardening rapidly. Brenda commanded them to stop. God, that woman had no clue. I wondered if I could take advantage of the situation to make her swallow my cum. She’d never done that before; only spat it out the few times I could cum in her mouth.
One more thrust and Rash buried himself balls deep in her ass. Anna let out a shuddering scream as her body convulsed. “Goddamn, she just came,” Nick exclaimed. As they lay there like an inverse Oreo sandwich, Anna began working her hips, fucking the two cocks in her. The squishy sounds returned. Her breathing became ragged, punctuated with moans, gasps, and occasional unintelligible words. Nick and Rash picked up on her rhythm, thrusting and retreating in unison, filling to the max, then emptying, just to refill again.
I could finally look away. Brenda was on her knees, the biker’s dick in her mouth and her nose in his pubic hair. I wondered how long he was because she never could deepthroat me. She’d gag with an inch to go. He pulled out until he left her mouth. OK, maybe five inches and not so big around. I noticed she didn’t close her mouth, and he slipped easily back in. I’d noticed over the years that she did vaguely respond well to being dominated, even though she claimed to not like it. I briefly chastised myself for not pushing that harder.
Pamela had seemed to choose her biker partner. Just one. He was standing, stroking his rather average-sized dick as he watched her undress, lay on an empty table, and begin masturbating. She slipped two fingers into her snatch, pumped them a few times, then pulled them out and moved them, glistening, to her mouth where she cleaned herself from them. Rewetting them, she moved them in a come-hither motion, drawing him over to her mouth. As he slid his dick into her mouth, she slid her fingers into his. He began massaging her tits and clit as he fucked her mouth.
