A man asks his sister's friend, whom he consulted about love, to practice sex. His sister's friend, worn down by his desperate pleas, allows him to kiss her and touch her breasts over her clothes... Then, reluctantly accepting the man's demand for sex, she agrees to 'cosmic play'. The excited man secretly applies an aphrodisiac to his penis and performs cosmic play. The aphrodisiac seeps through her panties, and unbeknownst to her, the sister's friend orgasms multiple times and eventually starts begging for penetration.
