Realizing the potential you cam have with this shirt, you try to see how life was like if you were born as a boy. Nodding to yourself in your decision, you undress down to your birthday suit in your bathroom and only put the blue t-shirt on, feeling a cooling sensation it covers your torso. You look over at yourself in the mirror and note the differences your male and female form.
Both sexes still had your physical apparance such as your hair, eye and skin color the same; however you had grown from your small statue to what you guess was the height of a 5'10 man. Your jaw was a bit more square-ish, remiding you of that hot movie star that you had a crush on. You were a bit more hairier as well, observing from the nice small stubble on your face to the noticable unshaved leg hair.
You pulled your shirt up to your neck and grinned at the firm muscle on your body from your abs to your nicely tone pecs you would had drool over seeing other guys with. Sure you were athletically tone as a girl, but you never able to see your abs like you do now. And you had a six pack to boot as well! Deciding you were done drooling over your abs, you focused on the nice little treasure trail that started from your navel and traveled down...down to your new male genitalia.
There was still hair down there, but it stopped at the base of your new flacid 4 inch penis, but there were some hair over your egg sized scotum as well. Deciding you had enough with just observing, you released your hold on your shirt and decided to grasp your new sex organ. Gingerly placing your left hand on your junk, you felt an electric surge throughout your body leaving you and began rubbing, wanting more.
You began to rub and without realizing it, thoughts of both guys and girls began to pop up in your head. You never really told anyone that you were bi. It, what it was, was building up, and you felt your dick harden till it rose up straight like a flagpole on a building wall.
All of a sudden, you felt a heavenly release that cleared your mind and seman poured out from your tip like firehose. The cum landed all over tiles as you accidently moarned out your ex's name.
Your dick's became placid and you felt incredibly tired. Deciding that you would clean up later and take a nap, you left your bathroom and put on your boy gym shorts that you kept from your ex and went to bed not realizing the magic that had sealed on your body...
