Welcome back to your therapy session! You say you've been having some trouble maintaining an erection ever since the maid walked in on you? That's a bit odd- ahh, and then she used your mouth as her own personal toilet? That makes a lot more sense! I know exactly how to fix this - I want you to take your cock out and start stroking. I'm going to tease you sexually to get you hard, so we can transfer those feelings into a more...appropriate place. But I really need to pee, and unfortunately I do think becoming accustomed to being a human toilet is better for you! So, get on your knees while I stand over you and use your mouth as a toilet, and then make you use your tongue to clean up my hairy pussy! I think this is the best method of treatment for you. Shall I make an appointment for you once a week?
