Suddenly the door behind you opens and your friend Will arrives, "I found your purse at my place. Boy I didn't know you were into dressup". He coudn't finish his sentence as suddenly he felt some prickling in his groin. Looking down he saw it growing in size, bulging out his pants which were also changing gradually to brown leather shorts. At the same time his feets were changing and turning into wheels connected to his legs at the side. Then his shirt changed into a brown leather jacket as a pilots hood with goggles grew out of his hair.
You grin at the new look for your friend, "You look sexy", and get close to him, starting to lick at his nose which started to grow into a rounded cone shape. Will started to moan, clearly aroused by this as his face was also pushing forward in the middle to follow that nose cone. Eventually small structures grew perpendicular to the cone quickly growing into a set of propeller blades.
Then you reach down to Wills crotch which already seemed full, in part thanks to the tight pants. As you touch it he shivers and his shorts split open as his crotch grows revealing a black rubber wheel hanging from in between his legs.
Will shivers in excitement from the arousal as well as his odd peril. Having no member anymore there seems to be no way for him to release.
