As I met my boyfriend's sister for the first time, I couldn't help but develop forbidden feelings for her... When we snuggled up together in the kotatsu, she seemed unusually close! Unbeknownst to me, she secretly performed handjobs laced with an aphrodisiac! Despite feeling uncomfortable, I was unable to resist and lost all sense of reason as she continued to pleasure me. Desperate for more, I begged her for even more of the drug. Trapped in a world of lesbian ecstasy that I could never experience with my boyfriend!
