I'm a little worried. No matter how often I jerk off I keep getting massive erections at the worst time, and I cum like a freaking river. I went to my Mom for help, and she said she will ask Aunt Susan, who is a doctor, what she thinks. When my Mom gets back from the Doctor's office, she tells me I have to cum in a cup several times a day and have it measured to see how much cum I'm producing! The one catch is that I need a little help, and since there is no one else around, a reluctant Mom has to help me out
