YSN-360 - I slipped the rumored drug into my nerdy sister who'd never shown any interest in sex as a joke, and it worked surprisingly well — she leaked while rubbing herself and latched onto my erect dick, refusing to let go - Mikoto Mochida

About this work

My sister outwardly hates sex, but she was actually a naturally horny woman! At school she's an elite, top student; she normally despises men, shows no interest in sex, and studies whenever she has free time. As an experiment I slipped an erotic aphrodisiac I bought online into her, and like a different person she started frantically rubbing herself; like a fish in water she latched onto my dick, straddled my face and pressed her pussy against me, so I let big sis have her way. With that drug removing the restraints of reason, even I, her brother, was shocked at how unbelievably horny the six sisters were — the forbidden relationship between six sisters and me. Six episodes in total.
