As you walk to gym class, you feel a pair of eyes from the coach's office, seeing a hot red head looking at you, she almost runs to the door to you. Taking your left hand, she pulls you into a small room with a small bed, smiling at you "you will be my clone, assistant, lover, and you will make others like me, as well as help me take care of my small children twin boys", right after she gently rubs your cock through your jeans. Your undeniably hard she tells you to strip as she does the same, both naked she giggles at your fat body, "you have potential, I chose right", your frozen as she pulls out your small, but hard erection, "this will be your first and last as a male with a woman, don't worry sex is much better, having a body like mine has so much advantages than a busty body". Looking at Ms. McAlders you can see her toned and muscular arms, she has your cock, she's working it even more as it grows in length, and width to satisfy her needs, the rest of her body is just as fit and hot, she swallows and moves to her back and orders you to eat her out, still in a daze from your first and last blow job, you see the rest of her body, as you dive to lick out her smooth, shaven region, she is moaning and giving you pointers, you seem to be getting better, as you feel a vibration all over your body. The first thing you can feel is your hair growing out and stopping at your shrinking shoulders, you can feel your body destroying fat as muscle is taking over, as your entire body is becoming like hers, with a cock and balls, your face is not your own anymore, becoming older to late 20's, you know this as your hair is red, and your eyes are now blue. She tells you to fuck her, you now feel all the gorgeous muscle you now posses, you smile and actually want and like this, she is smiling as you stick it in, licking her juices from your lips, she pulls you in for a kiss and moans in your ear "make it the best, for your last", as you shoot your load, your testicals are pulled in to become overies, your empty sack splits and swallows you cock, the rest of your male body hair is gone, as you moan like her, she looks at you "welcome Lydia McAlders, lover, assistant, don't worry you won't ever miss being a boy again", when finished your mind is filled with the new knowledge of being like her, you and Lauren are in the shower, washing each other and having more fun.
