24 hours, thoroughly back-breaking!! Penetrating defenseless, immobile buttocks!! Confining the restrained Aoi Kurusu! Forcibly making her buttocks exposed, injecting sperm into her vagina from behind!! Dirtying her plump buttocks with white liquid, smearing the spilled sperm on her pussy, kneading it deep with a vibrator!! Using various restraints such as pipes, iron pipes, and guillotines to take away freedom and back-breaking! After finishing, leave it. Then restrain and repeat the cycle! To turn the buttocks into a meat toilet...
