A female college student meets a kind and charming older woman who seems like the perfect big sister figure. The moment she visits the woman's apartment, she's suddenly taken and made to climax right at the entrance. On the sofa, her hands are restrained as she's repeatedly brought to orgasm, her embarrassment growing with each wave. Even while washing off her sweat-drenched skin, she's relentlessly pleasured until she's made to pee. Drunk on this new, overwhelming pleasure, she experiences endless waves of ecstasy. The two women take turns reaching climax, ultimately orgasming together in a final, shared release.
