I was always masturbating all the time, but my parents remarried and I got a sister-in-law. She's cute, but she's super methodical, so I can't stand her... Furthermore, he complained, If you're sloppy, you're masturbating too much! and unexpectedly ordered him not to masturbate! I can't stand this! When I was lamenting, my girlfriend's sister-in-law said, ``I'll make you finish masturbation!'' and asked her to squeeze my dick to control my ejaculation.
