Look yourself over.

Rising to your sexy slender little feet you can't help but take your sexy tits in your hand, absentmindedly asking, “What? I'm not a girl am I?” Of course as you are now alone no one answers. Looking into the mirror you are amazed to see a hot sexy little slut standing there. It takes a moment to realize that the person you are looking at is you, but to be sure it is. While you are now certainly not what everyone would call beautiful, but you are just screaming sexy, a bit to skinny with pronounced collar bones and a tiny waist, you could surely be some kind of a model as something tells you that any clothing you wear would look good, you would guess you are now around 5' 5” or so judging by how big the door to the dressing room now seems to be. Skinny as you are, and with sort of a lean and narrow figure overall, with not tiny but no bigger than B cup breasts, and he was right your nipples seem to have stayed a little longer than most you have seen, standing out a bit on your chest. Whatever magic there was it seems to have melted just about all the fat off of you as well as some muscle as you are now very different, lean and leggy with a short torso and with many of your bones sort of peeking under your skin, you are sure there is no way you are even 100 lbs. You have a perky slightly up turned nose with sort of pronounced nostrils. Your lips are full with very pronounced shape, very sexy. His pounding and rubbing your head against the floor seems to have done a number on your hair as well, while it is sort of full, a sexy tangle of nearly platinum blond on most of your head, the left side of your head is completely shaved to only a tiny layer of stubble. Feeling down and turning you decide your ass is definitely not what you would call big, but it is very perky, sort of begging to be fucked. You can't help but smile at the feel and look of your sexy ass and long legs as you turn back around. Your eyes are then drawn to the only thing that stands out as an oddity, your cock is still there, dripping a bit of cum, and just about 8” or so in length. “Holy shit, so I didn't turn into a girl after all. Well not exactly.” His words hit home of course right then, and you know you didn't fully change because you didn't swallow his cum. Just then your body seems to gurgle a tiny bit and out of your perky little ass squirts his massive load, that seems to hang there for an instant as if a single thing rather than a blob of fluid, then runs down your sexy long thin legs. Looking into your new sexy blue gray eyes as they widen with the realization of just what you might be able to do to finish the spell. With your sexy sort of squeaky new voice you find yourself saying, “So if I drink that I will become a girl for real, and if I don't I get to keep my cock. Fuck I wonder how long all of this will last?”
