Des:I was a horny boy who masturbated every day until my cock ran out, and my mother-in-law, who seemed to have been a slut and my fathers remarried partner, started living together. One day, I heard a strange noise coming from the second floor. My mother-in-law saw that my son-in-law was masturbating. My former slut mother-in-law was very worried that her son-in-law would never stop ejaculating no matter how many times. Just saying that doesnt count as cheating...your mother-in-law took off her skin...and her panties to save Musko, the sex monster.
