Mitsuki's days of unbearable humiliation push her mind to the limit. With her hands bound behind her back, she's completely helpless as a filthy cock thrusts deep inside her. Gasping for breath, drooling, rolling her eyes, and nearly passing out from overwhelming pleasure. Trapped in a hellish tickling frenzy, she screams in ecstasy even as she laughs. Constantly toyed with and treated like a female dog, reduced to a mere flesh dildo for satisfying desires.
