As you pull out there is a loud plopping sound, but it's a fraction of a second too soon. You feel somehow cheated, and Rico moans again as his own cock thrusts deeper into the mattress. You grab your cock to wipe it off, but something is wrong. Your cock head isn't where it's supposed to be. Your cock is an inch shorter. You run to bathroom to check yourself out.
"The curse!" you mutter carefully measuring your cock with your hand. It had been nine inches, now it couldn't be more than eight. You must be dreaming. So you try a cold shower to wake you. Of course it makes you smaller, but that's okay, because you look normal flaccid. You sigh in relief. It must've been your imagination.
You hear a sound from the bedroom. Oh, great Rico's awake. So much for your great escape.
"Man, I swear, my cock grew an inch!" Rico exclaims as you enter the room. "Your big cock must've pushed mine out further!"
Your eyes go wide. Rico's cock gained an inch? Maybe your cock really shrank an inch?
