You are a 13 year old boy, who's birthday is in about three weeks time. You are very into transformations and especially ones to do with anthro's even though you are oblivious to what could happen to you.
As you entered the toilets went left like you have always done your entire life. The toilets were empty - the same as the street you had walked through after buying from that strange shop. Anyway you quickly got to work and took the slightly odd looking soap and began viciously scrubbing at your hands in order to remove the traces of mud between your fingers.
After a while you looked at your hands and admired the work you had done- there was not a trace of dirt to be seen.
It was only when you had finished admiring yourself and your work through the mirror your attention seemed to wander to that of yourself being in need of a pee.
You began to enter one of the cubicles and let loose.
You looked at yourself and your penis which was beginning to grow a few dark hairs matching those on your head. At this moment a sensation took over you and you stood motionless.
