You sink your gloves hand into the cum balloon feeling how it sunk into it almost like an exercise ball. It was going to be hard for you to walk with this think dangling from the end of your monster dick, but it was not like you could make your sister do anything about it. Thankfully it looked like you didn’t have to, as soon your giant dong began retracting into your thicc thighs. Once you were left with little more than a chub it suddenly inverted into a fully functional vagina complete with a womb.
The suit then tightened even more around your crotch, the giant cum balloon was drained in its entirety into your stomach. You felt your own seed rushing inside of your Fallopian tubes tubes, ticking the walls like someone had hooked up a power hose directly to your cooch.
Every last drop was drained into you, your chest heaved and sweat streamed down your face.
Almost afraid of what you might find you look down seeing your midriff was just as toned as before, you let out a sigh of relief then placed a hand on it.
Then you felt your guts tightening. Before your very eyes your belly inflated, you felt something growing inside of you. Moving and alive. Two holes opened around your areolas and fresh milk spilled out onto the floor of your room.
You were now 9 months pregnant and ready to pop at any moment….
