JUQ-257 Running out of sperm with my sister-in-law

“Let's save money and sperm for a month until we can buy a high-end soap.” An ascetic life like hell began the day I promised my friends. I'm an avid masturbator, and I feel like the day is long. I kept quiet the semen seemed to pop out even when I didn't touch it, and was reaching the day before the soap. I witnessed the dorm mom's huge breasts and ass, which made me too excited after abstinence. I was in an extreme state, and my reason was blown away, and I fucked the dorm mom unconsciously.
