A Punu Special can only be performed when you need to shit, piss, shower, and masterbait. You go to the bathroom, sit down, hold your shit in and start fapping. Right when you jizz, take a massive shit. You might want to start shitting right before you ejaculate to make sure they both happen at the same time. Afterwords, don't wipe or clean up, and get immediately in the shower. After you wipe all the cum off your lap and wash all the shit out of your ass and it's all down the drain, plug it and start filling up a bath and light a kool blue cigarette.
Friend 1: Dude, I did a Punu Special today.
Friend 2: You have a fucking lot of free time on your hands.
