You're alone in the bathroom of a house, you've got a massive and very erect foot-long penis that cums at the slightest tug, and you have no good idea how to get out of all of this. Given your situation, you do what virtually any man would in your place: you give that cock a good, solid grab, and you start stroking furiously.
With every motion up its length, the latex dildo fires out a massive load of that pink semen, pouring it all over the room. Along the walls, across the floor, dripping from the ceiling, swirling down the sink, EVERYWHERE. With every shot, you feel an immense wave of relief and pleasure, one that's well-tempered by the immense wave of shame you get for feeling so good about jacking off this hard. After a while, you note that the massive erection is going down - you're at about ten inches now, and shrinking ever so slowly - and redouble your efforts. In fact, you're so focused with squeezing the everloving life juice out of that member of yours, you don't notice the slight bit of pink semen slowly dribbling down its length.

Looking down at the behemoth you just shrunk down to size, you sigh. Still not ideal, but at least this'll fit in your pants. Oh well, you win some, you lose... WHOA!
Only now do you see your hands. Unlike the cum that's coated the entire bathroom, which is surprisingly still, the stuff on your hands is bubbling and shifting like crazy. It almost looks like it's dissolving the flesh underneath, and you'd think that was the case if you actually felt any sort of pain, but all you can feel under that thick layer of pink is a sort of muted sense of the shifting happening on the surface. Even so, you seem to have lost control of your hands, as they twitch and wriggle uncontrollably. That strawberry man milk is doing something horribly, horribly wrong to them, and all you can do is watch as the bubbling and shifting slows and the stuff starts to move towards the more definite shape of a...
