Sex change

A hot feeling rolls up and over your entire body engulfing it in a wave of heat. You feel your muscle shrinking and your arms and legs growing more slender. Then you feel your ballsack shrivel up and disappear as you are stripped of your manhood. Then in its place a tight wet fuckhole is formed. Next to mounds of flesh rise from your chest and you remember what David said about huge tits and you can't help but feel a tingle of excitement in your newly formed pussy. The mounds continue to grow until they reach what must be an astounding g cup at the very least yet the still look firm.

"mmmm I'm so fucking wet" you groan
"excellent now just a few more changes to make"
