One day, I was called by my girlfriend's older sister Riho and her friend Honoka, a prostitute. As punishment for overpaying her for the 10,000 yen she borrowed, I decided to use her as a training ground for her adult entertainment debut! (I never thought I would ejaculate for the rest of my life on this day...) I was made into a slut with a sandwich with two big breasts, a sandwich titty fuck, a sandwich blowjob, and a sandwich reverse 3P, and my cock went crazy.
