"SUCK HARDER BITCH!!" Master screams at his new whore.  Ass stinging, Shelley sucks and tries to use her tongue to please her new Master.  It had been two weeks of feeding on nothing but semen. 
Master reaches around and strokes whats left of his\her clitty cock.  It had shrunk to almost an inch in length fully hard, which it remained that way all the time now. 
Master grunts and Shelley sucks down a load of his semen, and her clitty cock dribbles out a clear load onto the ground.  Master smiles at this, the former males mind now so conditioned to cum when she tasted male semen.  A few more months on hormones, and this one will be ready for sale.
