YSN-368 The aphrodisiac oil I was supposed to use on her, I impulsively tried it on my serious sister and she surprisingly turned into a slut and got played with.

The infamous aphrodisiac oil I bought for her, out of mischief, was given to my serious and non-erotic-interested sisters. Suddenly, their eyes changed, they drooled like animals, moaned while approaching me, and latched onto my dick without letting go. They squeezed out every drop of accumulated semen using every method imaginable, leaving me clueless about what to do... It turns out all six of my sisters were extremely promiscuous. My inappropriate physical contact with them.
