"I can come as many times as I want, and stay hard as long as I want."

With that whisper, it doesn't seem much has changed. You're still on the verge of coming, and you're vaguely afraid that your power might has worn off. Still, this feels too good to stop, so you continue to press into Colin's tight, wet heat. You do come, and your cock pulses as you pump your seed into him. You open your eyes with relief as you realize that, yes, you're still hard, and yes, you definitely feel like you could keep going.

And you do. You fuck Colin languidly, enjoying the way he tries to bite back moans as your fat dick scrapes at his insides and pushes your cum further in him. You re-angle your hips slightly and pull back, and then snap forward again. "OOOOUH!" Colin lets out a noise of sheer pleasure, and you're sure you've found his prostate. You smile and begin to fuck at an even pace, making sure to hit that little button inside of him with each thrust.

"Oh god, OH GOD OH GOD, oh nooooOOoooh- I don't want this, I'm not-AHH!- I'm not gay-ahhh!" You punctuate his protests with sharp thrusts. God it feels good to put him in his place. You reach forward and pull his hair, slamming harder into him. He lets out a primal scream of lust and you feel his ass tighten around you as he comes, spilling his load over your boss's desk. The feeling of his tight little ass squeezing you brings you closer to another orgasm, and you lean over him, grabbing him roughly by his slim hips hard enough to bruise and jackhammer into him. You grunt and grind yourself against his ass as you come again, filling him even more full of your seed. You can feel it frothing around your cock, and it's driving you wild. You don't let up and look at Colin's pretty face. He's ruined, whining and writhing as you brutally plunge into his ass.

"OhhhUUUHHhh God why DOES IT FEEL SO GOOD?" he cries out as he comes again, a weak dribble compared to your virile load. You grin as you realize you're going to fuck him dry. You lean over him, smashing him into the desk. You bite his shoulder roughly, and he cries out, beautiful and broken. You get an idea.
