Dave has a problem. He hasn't been getting laid lately. Turns out he has a pre-ejaculation problem. Its funny I'm sure, but this is a common problem amongst males. So I wanted to help him out. I recommended him to this great teacher, who specializes in these kind of issues. She calls it "cock control." How it works is she sucks your cock and tugs on it, but you have to hold it for as long as you can. Your not allowed to cum until she lets you. Then if you do good she fucks the shit out of you until your cock is red and almost to bursting. If you pass you get a certificate of banging that guarantees you to get laid if you show it to a woman. Dave loved the idea and went to meet her...he graduated! So watch and learn because there will be a test.
