[Reducing Mosaic]MRSS-018 The reason I became a middle-aged pervert's in-the-vagina sex slave instead of accepting a model offer Mikoto Tsukasa

Shi Mikoto is currently being kept as a dedicated insemination bitch for a perverted old man. Tied up with ropes or bandages, unable to move, she gets excited when her vagina is penetrated, feeling like she's being raped. She's subjected to bareback insemination and could get pregnant at any time. She has the style and looks to be an exclusive model for popular fashion magazines, but she turns down all such offers and lives this way instead. Why? This issue includes an interview scene.
