No, I want to go now (and stroke my new cock)

Smirking, you decide to give your body what it wants, standing and bending forward slightly, and feel yourself start to dribble from your new and unfamiliar penis into your shorts. It's an entirely new sensation to you, but you only falter a little, letting out a sigh as the soothingly warm piss drips down your legs and onto your feet. Your underside warms up from the piss soaking your panties and shorts, and you feel a turd gently press against your hole. You happily let it push its way out of you and into your shorts. It's so unlike what you previously knew, but now you'd be regularly filling up the seat of your pants with poop, padded up or not. You let out a moan as the shit fills up what little space it's given in your shorts, which appears to be steadily decreasing from the erection you're getting. You quickly embrace your new life as you grunt, pushing out the remaining poop into your soaked shorts.

You glance down, and along with seeing the tent in your pants, you see your piss flow all into one drain on your floor. Unzipping, you pull your rapidly hardening futa cock out and start stroking it. Your body shudders, already so close from the new situation you've found yourself in, and you try not to make too much noise as you learn your way around your "new parts." While the idea of dirtying your shorts with a third fluid, you're not sure that's nearly as acceptable as pissing and shitting yourself shamelessly.

Your body shakes as electricity seems to run through your whole body, while cum shoots from your cock onto the floor, making messy splatters that slide down the drain all the same.

It's an intense experience, and you crouch low as you catch your breath. That was certainly a way to start the day.
