Full Penetration and Chemical Interference

Alkim

Alkim lined himself up between those dripping folds and thrust in.

“Fuuuck!” Ania moaned from the **** of him.

He grunted, pulled back, and slammed into her cushiony ass with even greater momentum.

Ania yelped, her voice wavering with each thrust. “Ss-sOoo biiiG!”

Soon, Alkim found his rhythm, and the clapping of those fat cheeks echoed through the room like a sexy metronome. Ania’s back slowly arched down, further exaggerating the curve of her huge ass. He felt her pussy contract tightly, rhythmically around his cock but found both the sensation and the satisfaction of fucking a new woman disappointingly muted.

God, I hate condoms!

Alkim had already been spoiled by raw sex with his college FWBs, with their IUDs, and more recently by Mikaella’s constant blowjobs.

To his eyes, Ania was one of the finest lays of his life, yet it’d only taken a few millimeters of latex to spoil his fun. It was even worse now that he knew that latex barrier was preventing his chemically enhanced precum from pleasuring her insides.

He kept going, mechanically pistoning into her, trying to enjoy the sex as best he could, when he was suddenly struck by an explosion of sensitivity.

Ania felt it too, immediately thrusting her hips back to meet him, to exploit this increase in pleasure.

The **** and frequency of their fucking had almost doubled before Alkim’s rational mind finally understood what happened.

“Shit!” He hissed. “The condom broke!” Frustrated, he pushed her off his unprotected cock, and the seal between them broke with a loud, wet sucking sound. She whined at his withdrawal and fell flat onto her stomach.

He pulled off the broken condom and quickly replaced it. She started to get onto her hands and knees, but Alkim pushed her back down into a pronebone position that made her ass stand out even higher above the flat of her back.

“Don’t move, I wanna fuck you like this.”

“Then do it!” she begged, wiggling her hips as best as she could with his hand pressing down on the small of her back. “Fuck me like this!”

Alkim complied, shoving his hard cock back inside with a grunt.

Hot damn, her ass is amazing.

As he fucked her, Alkim kneaded and spanked those huge, globular glutes like they owed him money, playing her ass like a set of bongos. He couldn’t stop squeezing them, too in love with the feeling between his fingers.

That ass was all that truly separated Ania from the other rich, plastic, rail thin white women that traipsed around this city like they owned the place. Any doubts as to its authenticity had been well and truly fucked out of his mind. Ania’s ass jiggled naturally, the way only real muscle and fat could. What she brought to this bed just couldn’t be bought, not with all the money in the world. Cellulite and stretch marks were an acceptable price to pay for the sight of her homegrown body reverberating with each press of his hips: waves of soft, feminine skin rippling like water disturbed by a thrown stone.

The term “child-bearing hips” kept rattling through Alkim’s mind, and he had little doubt as to why her rich husband had chosen her out of the lineup of college-age gold diggers. Why he hadn’t knocked her up was anyone’s guess.

Unfortunately, after less than a minute of furious prone-boning and continuously pounding Ania’s padded ass, the second condom ripped.

“Argh! Damnit!” This time, Alkim felt the difference instantly, as did Ania’s pussy. It tried to hold onto him, squeezing tightly as he pulled out.

“Whyyyyy?” she moaned, lifting her head just enough to stare back at him with needy eyes. “Why nowww? It was just getting gooooood!”

“Shhh!” He spanked her **** cheeks, drawing out a whimper. “Give me a minute here.”

She pouted, but he ignored her. He peeled the condom off but stopped to inspect it more closely before throwing on another. Of course, he’d had condoms break on him before, that was always a risk of putting it on too quickly, of keeping it in his wallet for too long, or of using an “ultra-thin” variety that simply could not hold up to the stress of hard fucking.

He found the hole at the tip, yet when he tried to fit the torn ends together they couldn’t meet without stretching. That was odd. Still, Alkim was too horny to waste any more time on a broken condom.

He unwrapped and applied the third and final condom, but this one didn’t last more than a few seconds of jerking before it too burst open, loosing a sizable jet of precum that splattered onto Ania’s massive ass.

“What the fuck?” he mumbled to himself as Ania mewled with impatience.

Once is coincidence, twice is happenstance… three times is a pattern.

Understanding hit him like a runaway train.

Shit! The condoms didn’t just rip, they fucking dissolved!

Alkim concentrated on his Cowper’s gland, and quickly identified the problem solvent: glycerol, a fatty compound that can easily dissolve latex, not a normal component of human cum. Apparently his hatred of condoms was strong enough for his body to instinctively neutralize the one barrier to his pleasure.

Fuck me, guess all that cum doesn’t like to be contained…

He threw away the worthless protection and fell back onto the mattress, hands on his temples. “Fucking hell, we’re out of condoms.”

Ania got up into a kneeling position and turned to face him, or rather to face his dribbling cock. She crawled to his groin, lust in her eyes, and started jerking him off with both hands. “I’m clean… I promise…”

Though he shouldn’t have just taken her at her word, Alkim believed her; serious diseases couldn't stay hidden from a spouse, at least not for long. Besides, infectious diseases couldn’t hurt him, not when he could make novel antibodies on demand.

“Are you on birth control?” he asked.

She shook her head. “I can’t have any, my husband is infertile. He’d lose it if he found me with anything.”

Well, that explains why she’s never been knocked up…

“But I can take the morning after pill!” She volunteered.

He said nothing, and Ania wasn’t coping well with this delay. She clasped her hands together around his shaft in a lewd parody of prayer, “Pleeease?” she begged and jerked him needily.

Normally Alkim would never take that kind of risk, especially with a proven cheater. But this wasn’t a normal lay; he was here to make a deal, to gather information, while Ania was clearly **** to get back to fucking. Stopping now would be the ultimate cold shower; no way she would reward him for leaving her high and dry like that.

Fuck it, plan B then.

“Alright, morning after pill it is.” Alkim patted his thighs welcomingly, “Now, get up here. I wanna see you bounce on it.”

For Alkim, that was more mere dirty talk, but an important part of his experiment. He meant to test if his precum in Ania’s pussy would trigger the same ravenous, cum-hunger as an oral delivery.

Ania pounced on him before he could change his mind, climbed into a cowgirl position, grabbed his shaft, and guided his precum-coated cock into her drooling pussy. Her wet folds parted around the head of his cock as she began to descend. Slowly, she worked her way down until she was fully impaled, letting out a long, deep moan, like she’d been punched in the gut. The walls of her pussy clenched and hugged Alkim more tightly than any women he’d ever fucked, as if his dick had just returned from the war, and her cunt couldn’t bear to let go of him. She sat like that for a moment, pussy locked onto his cock, face melted in an unmatched display of lust.

Just as she began to relax, Alkim felt his prick flex, shooting a jet of precum right into her unguarded cunt.

“AAAAHHHH!” Ania wailed like a banshee, immediately confirming Alkim’s hypothesis. Those quivering smooth muscles of her pussy squeezed every square inch of his shaft like a velvet vice, while rivulets of juices flowed down his length, coating his oversized balls.

Alkim held her wasp-waist steady as she orgasmed from the mere act of penetration, moaning and grinding in his lap as she rode that high for a long and lusty moment.

Her lips curled into an “O”, and she sighed out a long,“Fuuuuuck…” as her climax finally subsided. Yet Ania was nowhere near finished with him. Her hips lifted slowly, rolling up and forward, until she slammed back down. She bounced and grinded on him like this for a couple minutes, but that quickly proved insufficient.

Each time he spurted inside, her bouncing sped up and up until she was smacking her beautiful, bubble butt against his thighs with manic, almost violent need, causing the unprepared bed frame to creak with the **** of her movements.

Holy shit!

Alkim just held onto that fat ass tightly and prepared for the ride of his life.
