[Hairu Nukemichi (Siina Yuuki)] Boku Swap Ane ~Akogare no Onee-chan to Karada o Irekaerareteshimatta Boku~ [desudesu] [Full Color]

Kouta adores his accomplished older sister Yuuri who praises his studies and dotes on him, until a sudden body swap leaves him stranded in her busty, hyper-sensitive body. Guided by a playful, teasing gyaru who promises to help him get used to his new curves, his first bewildering arousal and squirting climax quickly turn into hands-on lessons in kissing, titjobs and shared pleasure. As his own small body is boldly enjoyed by another and secrets like his hidden masturbation habits are exposed, the siblings spiral into a mischievous, affectionate triangle where tasting another's skin means learning every inch of it.
