...And sucessfully press the blade into it! In a last ditch effort, the soccer ball sized ballsack slams every drop of cum they have into you at once, causing your stomach to jump outward in the biggest load yet, forcing your arms and the scissors up, and severing the balls. You feel the flow stop and you fall back onto the floor, hearing a heavy thud as the giant scrotum slaps the wall of your kitchen. "I DID IT!" You shout in triumph, almost tearing up in happiness. You were free! You lie on the floor for a minute, relishing in the feeling of not being filled larger, but something was wrong...
You glance at your stomach and realise it's not actually shrinking? With some effort you manage to sit up, your giant stomach lying heavily on your thighs.

You give it an exerimental tug, and almost loose your footing as your vagina pulses roughly, the thick lips quickly opening and pulling it inaide before shutting tight, now letting off an erotic squeeze every few seconds, coaxing the dick to resume its thrusting. "Hng, god... at least it can't make me any big-gooohhhh..." you moan loudly as your vagina cuts you off as it pulses again, almost... angry at your remark. "What? My pussy wants me to be even more huge than this? No fucking wa-ohhh gooood!" Your comment ends in a shout of pleasure as you collapse, orgasming violently and causing you to convulse under the enormous weight of your womb. Eventually you settle down and manage to sit up, deciding that you should avoid talking about your size...
