I was supposed to fall for a girl in class, but as a virgin with premature ejaculation and phimosis, I couldn't bring myself to confess. Seeing my hopeless state, my private tutor, Rio-sensei, decided to stop the lessons and help me overcome my early ejaculation problem. But things took an unexpected turn! Her blowjob skills were incredible—instead of improving, I erupted even faster! I couldn't stop cumming! And her blowjobs kept escalating: high-speed vacuum piston blowjob, slow and teasing tongue swirls, pussy-to-dick P-to-M relay—each act pulling me deeper into pleasure. Does the teacher really just want to suck me?
