Yes, you make a huge mess

You're halfway through making a sandwich when you notice a strange feeling in your balls. It's the same sensation you might get if you're interrupted halfway through masturbating: a tight, slightly-uncomfortable tingling. It's also a bit like the twitching that happens shortly before an orgasm, only without the pleasure.

An erection soon follows, pressing up against the inside of your pants... And that's when the pleasure hits. The feeling is overwhelming, so you reach down to open your fly. Your cock pops out, and it's harder than you've ever seen it... And maybe an inch or two longer, as well.

You don't have much time to look it over, though: the brief contact between your hand and your shaft was enough to trigger an orgasm, and you begin shooting rope after rope of jizz into the air. You stagger backward and brace yourself against the counter, eyes closed as you empty your balls onto the kitchen floor. Each blast is the size of one of your normal ejaculations, and there's at least a dozen of them.

Halfway through your leg-shaking orgasm, your mother comes in from the patio. The doors are only a few feet away, and unfortunately that's well within your newly-enhanced "range." Two ropes of your cum end up on her thigh, making a complete mess. If that wasn't enough, her first step into the room goes straight into a puddle of your seed.

"Oh--OH! Oh my God, John, is this all your..?" She shakes her head in disbelief. "Are you okay?"

Right... People are a little more used to public indecency in this world. She's not free use, but she can tolerate this.

"I--Ungh... Y-yeah, I'm fine," you stammer, a few final blobs of semen oozing out of your slowly-softening cock and splattering at your feet. You can't help but reach down and stroke yourself a few times, staring blankly at your mother's bikini-clad and jizz-stained body...

...And before you know it you're hard again, jacking off at full speed.

"Wait, are--No, nonono. I don't know what's wrong with your--Your stuff, but I think you need a girl to help you out... And to make sure the kitchen floor doesn't get any dirtier."

"Wait, do you mean..." You stare hungrily at her.

Christine takes a few steps toward the hall, ignoring the fact that you're now jacking off to the sight of your own mother's bubble butt.

"GREG! Do you still have that jogger girl up there?" Your father yells a reply, but you don't catch it. "Send her down, quick! It's an emergency!" He yells again. "Well, so is John, and I guarantee that his is a bigger problem right now!"

You keep stroking yourself for a minute, watching your mom's rear end as she bounces nervously. Then someone else appears in the hall: it's a fully-nude girl around your own age, with huge tits that look even more massive on her slim, well-toned body. She's a little bit sweaty, panting as she enters the room.

"Hi, um, your husband said you needed me down--Oh, wow." She freezes when she spots your throbbing member and the mess you just made. "Um... Need some help?"

Your mother nods, placing a hand on the fit teenager's shoulder and guiding her towards you. "Quick, suck him off before he--Go, GO!"

You explode again, and the girl practically has to do a power-slide to reach your cock in time. Even then, your first blast gives her an impressive facial, and the second leaks out as she tries and fails to get her lips around your swollen tip. She finally manages it, though, sucking down the third, fourth, and fifth pumps. She gets into a rhythm, gulping again and again.

The feeling of her warm mouth around your cock drives you into a frenzy, and you grab her head with both hands to push deeper inside. Still cumming, you **** your member into her throat, pumping sperm directly into her gullet.

"Uuungh... Fuck, this is--It's..."

"...Gross," your mother finishes for you, retrieving a mop and bucket from the cupboard. "How are you doing this?"

"Guh... Guess I'm j-just real horny," you say with a shrug, pulling out of the girl's throat and then pushing back in. Soon you're facefucking her as she twitches, shakes, and tries to brace herself against your legs and the counter... But doesn't make any effort to push you away.

Your second orgasm is over now, but the sight of her naked, kneeling form and the feeling of her tight passage has you well on your way to a third. After a few moments, though, a sound in the hallway catches your attention.

"This is the emergency?" Your father Greg is standing at the door, a scowl on his face. He's fully-clothed, but his shirt is tucked in poorly and there's a bulge in the crotch of his dress pants. "John, I was right in the middle of using her!"

"It's okay, Dear, I was the one who insisted," your mother says. "Look at this."

"Look at--Oh, damn." His gaze falls to the mess that Christine is trying to clean up. "Is that all..?"

She nods. "Our son is having a bit of an episode, and he needs this girl's holes. She's just a random neighborhood girl, right? Can't you go find another?"

"I'm trying to get some work done, Christine," he scoffs, looking on jealously as you pound the teenager's face. "I don't have time."

"Okay, well, what if we have pizza for dinner? I can order from that place with the busty delivery girls."

"...Fine," your father sighs, turning on his heel and heading back upstairs. "Send her up when she gets here!"

"That man... Didn't even offer to help," your mother mumbles, getting back to mopping up your seed.

You take her queue, getting back to work pumping even more down your new cumdump’s throat. Your third orgasm hits just as your mother bends over nearby, and you can’t help but reach out and cop a feel of her exposed ass.

“H-hey, John!” She straightens up immediately, nearly dropping the mop. “Did you just—”

“S-sorry, Mom, I was reaching f-for her,” you murmur, still filling the girl’s throat with a hot, sticky load.

“...Okay then,” your mom says suspiciously, taking a step away before continuing her work.

Damn... That excuse probably won’t work twice, you think, cringing a little even as waves of pleasure wash over your body. I don’t know how long this SpermiZan stuff lasts, but having her around is gonna be ****... And when Sis gets home I’m REALLY fucked. I gotta figure something out.

For now, though, all you can do is keep humping the fit girl’s yielding throat. She’s not struggling much anymore, and you manage to bust two more nuts in her without any fuss.

That last climax finally seems to calm you down, and you will yourself to pull out of her mouth. She slides down to the floor, half-conscious and coughing up thick wads of sperm.

As you step away your mother moves in, mopping up your cum even as more flows from the teenager’s lips. She then grabs a dish towel and begins dabbing at the stranger’s tits, catching your loads before they can drip onto the floor.

That sight is threatening to get you hard again, so you quickly run out of the kitchen and back up to your room.

Your first experiment with the **** has been a huge success: not only do they work, but they seem to do things that your old world’s medicine can’t. The only question is, what should you try out next?
