[Takemaru Takasaki] Sexy Selfie Leads to Blackmail Cuckold Sex [Decensored]

One careless selfie hands a busty senpai over to a smirking underclassman, and the 'only once' promise collapses into nightly discipline that leaves her big breasts heaving and her pride in ruins. Between frantic bathroom-stall masturbation breaks—six in a single day—where she cums in a squirting, tongue-lolling mess, and rough sessions where he kisses her deep and defiles her until she nearly faints, her guilt over betraying Shogo-san curdles into the very spice of her submission. When the door lock clicks shut under her own hand, the line between victim and willing sex slave has already blurred beyond saving.
