Unemployed and down on his luck, Kenta moves back to his rural family home. His brother soon arrives with Alisa, his stunning Russian wife. Her innocent smile, massive breasts, and huge ass instantly captivate Kenta. When the brother leaves for an extended business trip, Alisa struggles with loneliness and intense sexual desire, secretly masturbating every night. Kenta spies on her and devises a lewd scheme — using “Japanese cultural lessons” as an excuse to get close, touch, and eventually have passionate sex with his sister-in-law.

Each episode features Alisa in various scenarios (ghosts, festivals, wet clothes, maid outfits) where Kenta’s “lessons” lead to wild, creative hentai encounters filled with creampies, paizuri, ahegao, and more. Alisa starts shy and polite but gradually becomes addicted to Kenta’s touch, enthusiastically participating in his perverted teachings while mixing Russian words with broken Japanese. This erotic OVA series blends slice-of-life countryside setting with nonstop explicit action, focusing on the contrast between Alisa’s pure appearance and her growing lust. Produced by Collaboration Works petit, it’s a classic hentai comedy full of big-breasted foreign wife fantasies and taboo family relations.
