[Terasu MC] On the Laptop My Beloved Big Sister Lent Me…

A bespectacled young woman with a beauty mark, black bobbed hair, and a rebellious streak accepts a borrowed laptop from her beloved older brother—only to discover a hidden folder of recordings of him with another woman. The cover declares "オタ系お姉ちゃんNTR," framing a tale of betrayal as she spirals deeper into obsession, stalking the rival lover, watching the footage on repeat, and ultimately propositioning the older man herself in a desperate bid to replace her brother in his bed. Sweaty, heavy-bosomed encounters unfold between the curvy younger woman and the graying, older lover, masked encounters in public, and climactic moments where she films herself as proof of her conquest—raw jealousy weaponized into seduction.
