At first

Going to the fridge you grabbed a Gatorade but noticed in the back what appeared to be a medicine package. Martin had some odd friends in high school so he knew what street X-change pills looked like. The remaining pill was a blue pill and he could try to use it to turn back. Grabbing it he almost took it, but stopped himself. Street pills couldn't be taken together within the first few hours without creating random effects. including a temporary lock to the form. The worst case, one of his friends had to spend 3 months as a horny thoughtless bimbo as the result of a bad joke.

Martin quickly formed a plan. Grabbing a glass from the cupboard, he quickly poured the remaining juice and mixed it with the Gatorade. Cutting the blue pill he placed a bit of it in the bottom of the glass and took the drink to Tony in the room he was just fucking in.

"Hah so you knew I was going to send you for a glass." Toni took a quick swig and the chugged the rest down leaving an empty glass. Passing him the bottle Martin brushed his hand through Tony's hair but nothing came out.

"GAH!" Tony dropped the bottle and passed out from having a mixed dose of street pills. Smiling at the collapsed idiot, Marting actually plucked a few good hairs before the transformation actually affected the hair. It took a bout 20 minutes for the change to complete but the new "Toni" was a beauty. In that time Martin cleaned herself up. She even dug out one of Tony's baking timers so she could game while waiting until it was safe for part B of her plan, to ruin Tony's life.

To do that, she had the rest of the blue pill dissolved in a glass of milk along with those hairs he plucked. When the timer went off Martin drank the concoction. The pain nearly had him scream in pain, but it wasn't enough to put him out like it did to Toni. It took about 5 minutes to finish but looking in a mirror, he had Tony's face. Looking in his crotch, he had Tony's dick.
