One day, I was called by my girlfriend's sister, Riho, and her friend, Honoka, a prostitute. As punishment for defaulting on the 10,000 yen I borrowed from her, I was made to be a practice dummy for her debut in the sex industry! (I never thought I'd ejaculate more than I'd ever needed that day...) I was sandwiched between two big-breasted women, and they gave me a titty fuck, a blowjob, and a reverse threesome, milking me of my ejaculations and creampies until my dick went crazy...! I wonder if a practice dummy even does things like this...
