MMUS-085 My body is an experiment for J〇 girls! Before I knew it, my house was a hangout for J〇 girls and I was played to have sex with them all. – Mitsuki Nagisa

To the girls, my body is merely a test subject for sex. But I get an erection quickly, so I do as the girls tell me to, even ejaculating. They make me massage my breasts to make them bigger, tease me erotically as practice to arouse my boyfriend, and finally they come to my house and use me as a hangout spot. But just watching the girls relaxing with their panties exposed makes me get an erection again.
