Long enough for you to cum twice!

"OH FUCK THAT'S HUGE!" Screamed Paul.

"Mmm, that's just the head..."

You continue pushing the head in, eventually feeling the 'POP' of your cockhead getting through Paul's tight ring. Paul whimpers as he feels you push the rest of your cock into his ass, not stopping until you felt his bubble butt up against your abs. Paul moans out loud at the feeling of fullness, something he'd never experienced before.

You watch as you start to build your pace as Paul starts shaking more and more before he arches his back and moans out his release, cumming hands free onto the floor of the Mail Room. He groans as he looks back at you and mouths 'fuck me', that is a proverbial red rag to you and you start to pound him senseless, your balls smacking into his at a rate of knots, you know that you're going to cum quicker than you'd like, but you also know that you'll stay hard.

"Ready to be filled with the first load I'm gonna dump inside your fertile womb Paul?"

"Oh God yes, please fill me. Make me your bitch!"

You growl loudly as you pound him harder and harder until your balls start tingling more and more until you hold your cock at the entrance to Paul's womb and spew out your hot load, flooding his defenceless uterus.

"So warm... I can feel your hot seed, searching for my egg(s)… They're helpless... Gonna be conquered..."

"You know something Paul?"

"W-What?"

"By the time I'm done with you, you'll not only look pregnant and be limping, you might well be a hot, drooling mess. Because I can go again, you feel my cock, it's still hard my little breeding bitch."

Paul looks nervously at you before gulping and whimpering as he feels you starting to go again.

An hour and a half later...

Paul is just as you described, he's practically ****, his head slumped on the floor, drool pooling out of his mouth, a puddle (pretty much a river) of his cum underneath him as you get closer to your peak. You can feel the sweat dripping down your chest, a healthy sheen covering your skin as you start to feel the rumbling from your balls and start to get into your finish. After another minute or so, you push so deep that you pop into Paul's cervix and pump him full (again) with another heavy load of your potent cum.

You stay put until you feel your cock finally start shrinking and keep it in as long as possible to ensure that all of your seed stayed in. Reaching down, you start untying Paul's limbs, which you'd thankfully tied with soft silk ties to keep damage to an absolute minimum. Once he was untied, you softly woke him up and kissed his cheek. After you both got dressed, you took a can of Febreze and sprayed the hell out of the Mail Room to mask the smell of sex.
