[Takino Mishin] I Will Protect Senpai’s Body [biribiri]

A devoted kouhai wakes up inside his senior Aizawa's curvaceous, big-breasted body just as the lecherous teacher who has watched her for three years finally closes in, forcing him to feel every groping hand and unwanted touch through her sensitive frame. Swearing to protect senpai's body at any cost, he endures the older man's blackmail, lingering fingers, and forceful coupling on the tatami floor while the dilf predator murmurs that the two of them have always been one. As resistance blurs into a heat he insists he can't turn back from, this body-swap nightmare teases a protagonist sinking ever deeper under his teacher's obsession.
