"OH FUCK! FUCK YES FUCK!" Jeff screamed as he felt the already massive tool slowly growing inside of him, fucking him deeper and deeper. He opened his eyes just in time to watch the already massive mailman grow even larger, his muscles slowly growing big enough to make even the biggest body builders weep with envy.
"Oh fuck yeah, I love you're ass baby. I love it so fucking much." The mailman moaned.
Baby?
Jeff didn't get much time to think about that as a sharp crack signaled the breaking of the bed frame, sending them both to the floor but not interrupting their ducking for even a second.
The mailman's groans and grunts got steadily louder, as did his giant body and gargantuan prick. He rammed Jeff deeper into the bedroom carpet, making him scream with pleasure.
"Oh fuck, I'm going baby. I'm gonna fill you up." The mailman managed to say before uttering an earthshaking roar and unloading an unholy amount of cum into Jeff, forcing his belly out and spewing out his ass. Jeff came too, much less than the other man but it was still the most powerful orgasam he'd ever had. Panting and sweaty, the two lay among the broken remnants of the bed. Finally the mailman gave Jeff's neck a kiss and began pulling out, and out, and out.
When Jeff finally felt the head leave his ass with a pop, he felt the most incredible emptiness. Weakly lifting his head, he looked upon his creation. The mailman was now a staggering 7 feet with close to 400 pounds of beautiful, sculpted muscle. His cock stood, still erect and leaking, topping out just below the man's nipples and thick as a wine bottle.
"Oh god, Jeff, babe, that was a fantastic first round. I love you so much, especially when we get to role play like this."
Baby? Role play? Love? What the he'll was going on? And why had the man started growing again?
"Rich," Jeff groaned, how the hell did he know his name? "Pass me my laptop for a second."
The mailman, Rich, did as he was asked. When Jeff saw the change history, he understood what had happened. In the heat of the moment, one or both of them had bumped the computer. The result had given Rich an extra shot of muscle and had rewritten history so that the 40 year old mailman was now a 30 year old super stud who the 16 year old Jeff was secretly dating.
Before Jeff could so much as make sense of what had happened, he heard two voices come from downstairs.
