Kevin struggled as his girlfriend Rebecca held the funnel, and another strangers cock shot it's load into it and it flowed into his open mouth.  The tingling intensified in his body, his hair lengthened more, he felt his ass swell and the weight grow on his chest... Kevin's cock almost hurts as it tingles and as he gurgles and screams in pleasure, shoots a load of cum into a cock sleeve attached to a small house, leading to a baby bottle already half full.

 

Seeing the terror in his eyes, Rebecca laughs, "This is what you fucking deserve you pervert, reading all those transformation stories.  What you didn't know was I'm really a witch, and have the power to make your sick dreams come true!  Enjoy your new life, slut.  It's permanent.  AND the good news is you won't age a day, you'll be like this forever!"

 

Choking down the fresh load, moaning in shame, he\she feels more of his\her maleness slip away... another man walks up and the process continues...

 

4 hours later, Kendra's new pussy is pounded by the cock as she screams in orgasm, her new tits bouncing on her chest, her fleshy ass jiggling to each thrust.  2 hours ago her clitty cock finally spurt it's last load and became her new clit, and her pussy lips formed.  Her pussy finished developing shortly thereafter, opening with a flood of clear pussy juice, and immediately itching for a cock to fill it. 

 

It didn't take long after that for the first, second, and 10th man to fuck that pussy and fill it with cum.
