A beautiful and charming sister active in the rhythmic gymnastics club! Her brother, seeing her practicing at home in a splendid leotard, mixes a powerful aphrodisiac into her drink. Pretending to be concerned about his sister's strange behavior, he touches her sensitized body, driving her to lose all reason! Driven wild with desire by the aphrodisiac, the sister sucks on her brother's erect penis and inserts it herself. Her reason completely shattered by the powerful aphrodisiac, she comes repeatedly in a backward-bending orgasm while still wearing her leotard!
