As he heard the sound of Malcolm drying his hands Preston breathed a sigh of relief that at least he hadn't been caught. Malcolm seemed to be wrapping up his phone conversation.
“Oh remember to return my black umbrella this Saturday! Talk to you later, Bye.”
As the bathroom door opened a strong draft blew through the room. Preston was too distracted by yet another sudden orgasm to stop the stall door from loudly banging open. The sound alerted Malcolm who turned around. His eyes immediately locked onto the tiny ejaculating dick and when he recognized who that tiny dick was attached to, he burst out laughing and walked towards Preston.
"Damn I knew you were a two pump chump, but who knew you'd have such a useless microdick as well Prejac."
Preston grabbed another wad of toilet paper to wipe his dick again.
"S-Stop calling me that Malcolm-uuugh. Get out!"
Thankfully he was already wiping his penis and his next load pumped directly into the toilet paper so Malcolm didn't see it.
“I don't think you're in any position to be telling me what to do Prejac. Do you think you'll have any standing at Vorbicum Industries once I tell the boss about your on the clock masturbation sessions?"
Before he was even soft again another volley of semen soaked the toilet paper beyond usefulness. He threw it away and went to grab more only to find there was no more in the stall. He saw Malcolm turning to leave and called out.
"No! Wait! Please! Don’t tell Mr-”
*Bang* The men’s room door flies open yet again and in walks their boss Mr Cummings, a very large and presently very angry man. Preston yelps and quickly covers his tiny dick with his hands. Malcolm turns to the sink and pretends to wash his hands again.
“Jackson! I thought I heard your voice." Mr Cummings bellowed, "What the hell are you doing? You were supposed to come to my office half an hour ago!”
Preston tried to suppress another groan and it came out as a high pitched squeak. His little nub released a squirt of cum into his palms. Mr Cummings did not pause in his tirade.
“You can't seem to even get the simplest tasks right can you Jackson? Do you even know how to read? The stall is clearly marked out of order. Your incompetence astounds me.”
Preston whimpered again as another load of spunk filled his cupped hands. Malcolm was at the sink washing his hands and barely suppressing a smirk. Mr Cummings turned towards the exit.
“I suggest you quit your whining, put your tiny dick away and get your fat-ass in my office NOW if you want a future at this company!”
More semen pulsed from Preston's microdick and started leaking out between his fingers. Thankfully Mr Cummings didn't see this as he immediately left after finishing his rant. Malcolm however had witnessed everything in the bathroom mirror and could see cum oozing out over Preston's knuckles.
"Fuck no way, did you just blow another wad while the boss was yelling at you Prejac?"
"N-no! S-Shut up!" Preston turned completely red and closed the stall again with his cum dampened hand as Malcolm left the bathroom laughing.
