"If it's just incontinence and ejaculation, then it's not an affair, right?" He consulted his girlfriend's sexy younger sister about sex, only to be played with for premature ejaculation and subjected to exhibitionist orgasms through ejaculation training. (Saito Amiri MIAB-545)

My sex life with my girlfriend wasn't going well, and my worries were discovered by my hot younger sister, Ami! I was just there to kill time and find it fun, but she teased me with that "Let me see your boyfriend's dick" look! While I was rock hard, ejaculation was almost scheduled, and I nearly came! I suffer from premature ejaculation, and she teased me until I peed and ejaculated! I have a girlfriend, but I was seduced by masturbation! Just playing with my nipples kept me erect, my urge to ejaculate was endless! I wanted to ejaculate, but masturbation stopped me, so I could only ejaculate involuntarily! It's all Ami's fault… I'll develop weird fetishes!
