(C66) [Kouzuya (Kouzu Sousuke)] Kinobori?

Onii-chan, a muscular brother, carries his younger sister Kotori-chan up a mountain, their bodies pressed together as summer heat fuels a forbidden intimacy. The scene shifts to a tense encounter where she protests, yet he insists he will help, moving her against her will while she is forced into a helpless position. The story continues with a cruel seduction, as he commands her to lie back, spreads her legs, and teases her with promises of lubrication and a forced blowjob, heightening the sense of non‑consensual desire.
