It'd be rude not to

Smiling, you walk up to him. Taking your dick, you ease it into his ass. Unlike before, he gladly accepted your intruding member. The hunky daddy moaned in bliss as he was filled up with your fat cock. You relished in the feeling of slipping your rod into an inviting hole. The lusty groans from the other man were music to your ears.

"Fuck," James moaned, "that feels so good."

"You really like my dick, huh?" you ask.

"You know I do." he grunted, his pleasure betraying his annoyance, "You made me love it. But, uhh, but it really does fill me up so fucking good."

You began slowly pumping in and out of him. James slowly rocked into your thrusts, adjusting himself to your thick penis. He may be turning into a cockwhore, but he is yet to take cocks with ease. Especially with no lube. You cherished his **** efforts to take your cock in its entirety. He still had some inches to go, but was desperately wiggling and atuning himself to reach down to your pubes. His grunts from sparks of pleasure encouraged you as you kept sinking into him. You pulled back slightly, making him whimper at the loss. In not time, you thrusted back forward. He moaned at being refilled, especially as you etched further into his rectum. Eventually, with much thrusting, your pelvis met his cheeks.

"I'm completely in, boy." you say, pushing your dominance.

"Oh, fuck me, please." he begged, leaning back into you.

"As you wish."

At that, you pulled back before slamming back forward. You had a lot more vigour than previously, knowing he was a lot more ready to handle your fuck. James moaned as he began to experience his first, self initiated man sex. His voice would break as you began slamming him into the desk. You grabbed his hips to get a better grip, before jackhammering into his jiggly mounds. The sounds of grunts, groans and slapping balls filled the office. You hoped the workers outside heard. Someone opening the door to find their boss getting assfucked into submission. With James' newfound interest in dick, you're sure he wouldn't mind. Well, as long as they filled one of his holes.

"Tell me you love my cock." you demand, pounding the businessman.

"O-oh fuck, I lo-ove your pri-ick!" he moaned, voice shaking with each thrust.

"Tell me why you love it."

"Fu-uck, it's fill-filling my ho-ole so goo-oo-oo-ood." James groaned.

"No, your pussy." you say, speeding up, "Your little mancunt. You love big dicks in your needy twat."

"M-my manpussy." he panted, also getting close, "Ye-ah... fuck my pu-ussy."

You hammered into James' hole, or his cunt as he would now know it, with great ferocity. You could feel the cum ready to spill. With a roar, you finally unleashed yet another load of cum into the horny businessman. You pumped his guts, enjoying his hole squeezing each drop out of your cock. You slowed your thrusts down into calm strokes. When you pulled out, James burped some of your cum out. You nearly demanded he lick it up, but there was always time to perfect the cockslut. As he shakily stood, you could see he'd cum himself at some point. Semen dripped from the desk as his shiny cock still had drops of cocksnot hanging off of it. He looked up at you, his gaze permanently changed from the previous disdain to curious horniness.

"Holy fuck." he panted.
