Brad had thought that Will had left for the day, so he used his transformation rock to become a twin of his younger sister.  Will snuck back into the house and was watching as Brad changed into the small woman.  

Will watched Brad as he slid on a thong and started playing with himself in the mirror... Will's cock got hard as he watched the show.  Brad closed his eyes with the feelings running through his body.

Will quickly stepped into the bathroom, grabbing the moaning girl by the hair, and quickly slid the thong to the side and slid his rock hard cock into Brad's soaking pussy.

Brad yelped in pleasure and surprise as Will quickly started thrusting into her, her breasts bouncing, her ass jiggling.  Grabbing onto the counter and mirror Brad could only beg for Will to stop. 

 "Ppppplease  WWWillll don't.. UUgggg don't cccccum in meeeee pplleeeaseeee!  OOHHHhhhh pleaseeee.... It willl be f..ff..ffforevvver..."

Will looked down and felt Brad's pussy clench down on his cock.  "Looks like you like this alot BRAD... Or should it be Bridgette?  Since you seem to like this so much I think it should be permanent, slut!"

Bra... Bridgette squealed in pleasure as she felt her body give into it's first orgasm... Wills balls slapping against her clit... screaming loudly.  Eyes widening, she feels Will's thrusts go deeper and his cock throbbing, then the feeling of his semen shooting deep into her womb, her new body tingling and her body convulsing in another orgasm, as her body assumes it's permanent form.  Her mind empties itself of useless male information to be replaced with the mind of a slutty bimbo...

"Fuck me harder big daddy, OOOHh fuck your slut!" Bridgette screams...

Brad is gone, Bridgette is here to stay!
