彼女の妹の巨乳誘惑〜お兄ちゃん、私と良いこと…シましょ？〜 The Motion Anime / Kanojo no imouto no kyonyuu yuuwaku ~ Onii-chan, watashi to ii koto… shi masho ~ The Motion Anime

Adapted from Appetite’s PC game, 彼女の妹の巨乳誘惑〜お兄ちゃん、私と良いこと…シましょ？〜 (Kanojo no Imouto no Kyonyuu Yuuwaku), this motion anime brings to life a tantalizing tale of forbidden desire. Released on January 17, 2025, this 37-minute animated feature follows Meru Narasawa, a playful, busty little sister with a devilish streak, as she sets her sights on her older sister’s boyfriend, Kengo. What begins as a mischievous urge to “steal” what belongs to her sister soon spirals into something deeper—and far more sensual.

Meru, a curvaceous and mischievous girl, has always coveted what her older sister, Ai, possesses. When she meets Ai’s kind but slightly pushover boyfriend, Kengo, her playful teasing takes a seductive turn. Initially driven by the thrill of temptation, Meru lures Kengo into a steamy encounter, only to discover an undeniable chemistry between them. As their secret rendezvous intensify, Meru begins to wonder if she can make Kengo hers for good—leaving him torn between loyalty to Ai and the irresistible pull of her little sister.
