... he fills you in.

While there was an extreme urge to just hold back and go with the flow, your wariness towards pregnancy gave you enough strength to eventually gasp out a "W-wahhn... wait... re... remember to pull out... mmm... it's dangerous... can't cum in..." when you felt him rut you with renewed vigour, obviously approaching his own limit. Yours? You had been randomly cumming all the while, reason for your objection towards creampie to come so late.

Well, lately you got some discreet success in avoiding Big J's creampies, especially during your dangerous times, so you didn't really want to risk your eggs in a random quickie with an equally random man.

Too bad for you however, since Martin had no intentions to listen to your plea, instead laughing "Dangerous? Didn't you follow me here because you like bad guys? Dangers are part of the fun, babe. Since you asked for an insider, i'm gonna give you the biggest creamy insider of your life"

Hearing him express so openly just how little he cared about your opinion made you tighten up in trepidation and fear, though he took it as you getting more excited for what was to come "Tightening up, uh? What a good slut. Right, squeeze me well, i'll make sure to fill you to the brim. Sorry if i knock you up... still not gonna be responsible for it though"

A smug laugh followed his irresponsible words, omen to an equally irresponsible ejaculation right into your defenceless and fertile womb...

"Here it is, an insider right up your cunt. Be grateful, bitch"

This was his last comment before doing what he set himself to do, namely blasting your uterus with as much spunk as his balls could pump out.

Each twitch of his cock squirted a jet of cum right through your cervix, splattering into your deepest and filling you full of white stickiness...
He wasn't able to fulfill his promise, Big J creampies were much messier than his when he was dead set in pumping you full, but nonetheless the amount of jizz currently overflowing from your cock-plugged hole was still worrying enough when considering just how fertile you were.

Bashing him for not paying attention to your plea... was what you would have done, but strangely the white waves of cum not only made you cum hard, but also washed your rationale back into the deepest recess of your mind, turning it into a powerless onlooker while your most instinctive side got control of your body, led by the same "go with the flow" binding thought that was currently keeping your rational side at bay.

Result?

Meekly mewling in submission while accepting all the cum he could fill you with, a reaction e was very satisfied with.
In fact, even after he was done cumming, Martin kept his cock within the warm embrace of your pussy, commenting with a satisfied voice "Damn, definitively the best fuck of my life. You've got a great cunt, slut"

Slut? You? Full of rage you leashed out... not, something telling you it wasn't that big of a deal and that you should just accept compliments as they came, which in turn prompted your lips to agree with a "Yesh... thanks... you got a great cock too... could get used to it..."

"Right?" He was delighted, while at the same time wondering if it was the alcohol speaking or if you were just that much of a slut and only managed to keep it under wraps till now. Not that it mattered, as he jumped on the chance to propose "Then we should go steady, would love to fill you up everyday"

"Is that so? Dunno..." something told you it wasn't right to do this, but something even more persuasive made you feel like it wouldn't be that bad to go steady with a guy and get railed everyday. Be it girlfriend or cumdump, wouldn't it be nice to have a nice cock to rely upon?

Luckily for you, or maybe not, Martin panicked a bit at your indecision. Were you just affected by the alcohol after all? If he didn't play this well, this may end up as a simple one-night stand. Well, if you weren't agreeing now, how about after another few rounds?
Thinking so and unwilling to hear a possible refusal from you, he cut you short and replied instead "No need to answer now, we've got the whole night after all... how about we go for a drive first? I'm sure your legs would like some rest after getting pounded for so long"

Indeed, your legs were so weak you weren't sure you couldn't stand without his help.
You nodded, and he pulled his cock out of you. A fat wad of cum followed after it and splattered right into your lowered panties.
With a snapping sound you didn't notice, Martin got a close up pic of your creamy slit with his phone, pulling then your panties up into place without giving you the chance to clean yourself out... a chance that wouldn't come back since he then also helped you into your pants, making sure any cum leaking out of you could only pool up into your underwear and keep your groin as sloppy as needed.

You? Going with the flow, you had no will to go out your way to pull your pants down and anyway, once the vibe was again against your pussy, you had more pressing matter to attend.
