Foursome!

Once the four is us caught our breath, we moved to the bedroom for a more complete and proper fucking. With us all naked on the bed, I admired the erotic contrast of my wife's Slavic complexion on the two darker olive skin tones, as the three women started to grope my pink pussy pleaser. Tongues and lips explored my shaft and balls, their huge titties jiggling and slapping against skin as they worked my princely prong. They smugly observed that even my big dick was easily hidden in the spacious cleavage of their improved boobs.

With sensual deepthroating and warm triple titfucking, the enhanced vixens coaxed me into cumming three times - twice filling a mouth (and then snowballed) and once onto their funbags - before we moved on to licking pussy. Two of the babes would 69 as their remainder straddled my face, insisting on delivering a load of girlcum in my mouth to the tune of my tongue lashings and switching positions every time they came. My stately dick stood erect and neglected as Svetlana, Debra and Stacy received cunnilingus from me like they expected me to be grateful for the opportunity.

We finished off the afternoon with actual fucking. Stacy was first, climbing on top and bouncing her hot cunt on my cock while Debra and my wife cuddled off to the side.

Stacy's first time getting fucked by my big cock was hot and heavy. The sexy Asian chick towered over me, working my cock over with stroking squats, large breasts shiny with sweat. We came simultaneously, our crotches slavered with juices.

Without missing a beat, Debra lead me over to her and had me fill her cunt with my cock. Stacy sucked my balls as I drilled Debra's boiling pussy, Svetlana egging us all on. When she ran her tongue down my shaft and then sucked Debra's clit as we fucked, we both orgasmed from the pleasure.

Svetlana almost instantly replaced Debra, giving me not much of a chance to recover. On one knee, she rose above me, angling my dickhead between her dripping pussy lips. This was her favorite position. Above me, she could gaze down as she drove herself down and down my cock. Taking as much as she could, she could experience one orgasm after another while I caressed her tits, stroked her back and played with her clit. Watching me stare in amazement at her gigantic tits excited her.

Despite her energetic thrusts her boobs didn't really rise and fall. They didn't slap her torso. They were too big, too solid. Instead, they just shivered in time with her movements.

I couldn't take my eyes or my hands off her ridiculously fat tits. Over and over, my fingers tried to squeeze her boobs. Strumming her nipples with my thumbs caused them to become as hard as rocks. From time to time, I raised myself up enough that I could lick and suck her knockers. I loved the way they jutted out from her chest.

Suddenly, her pussy clamped down and my cock was enveloped in a tight hot vice. She rolled her hips as her pussy muscles worked my cock and I moaned.

I was going to lose it soon if I didn't take charge. So I pulled my cock out almost to the tip and then slammed it back down with a grunt. The expected scream didn't come. She simply purred. I began to pound into her, giving her all I had. She matched every thrust with her hips and her velvety cunt continued its magical contractions. I felt my balls contract and I tried to pull out to stave off my orgasm, but she wasn't having it. Her legs wrapped around me and she sped up the pounding of her hips.

"Come on, stud. Give it to me." She said huskily and then lifted one of her magnificent tits, sucking a hard nipple into her mouth.

And just like that, it was over all too soon. I blasted my cum into her, having the best orgasm of my life. My body tensed up so tightly and it felt like her pussy was sucking the life from me. When I finished I felt exhausted and collapsed on the bed next to her. Svetlana spread her legs, slid out my cock of her with a plop and waved over Debra and Stacy to finish her off by double-teaming her cum-soaked cunt. It took the two Vietnamese babes five minutes of tasting my wife's honeypot to make her finally go wide-eyed and cum.

I was exhausted for the rest of the day. Svetlana, meanwhile, rose like a Phoenix and started trying on clothes with Stacy and Debra. The two Vietnamese sexbombs had packed several cases of spare clothes for their trip. Despite the relative tameness of the shirts and pants, they still looked slutty on the three women, thanks to the mutagen's invigorating effects. Their massive stacks stretched sweaters and blouses. Svetlana's extra pairs of leopard print bra and panties fit Debra and Stacy well enough, but Svetlana had to modify her own pair to handle the upgrade of her body. The effort was worth it, as seeing all three enhanced women wearing such naughty underwear made for a stunning display of sexuality. I popped my last boner of the day at the sight, which Sally relieved with a masterful blowjob that had me squirting directly down her throat in minutes.

With that, I nodded off, the three women quietly leaving me to sleep. What they did, exactly, while I slept, I do not know. But I can guess, judging from the trio's satisfied grins, lustful touching of each other's breasts, giggling whispers and sexy outfits, that they got up to something very naughty indeed.
