[Fuzuii Undou (Fuzui)] Shoujo Kankin Kairaku Kanraku {Hennojin}

A twintailed grade-schooler named Momo-chan learns exactly why a girl with growing curves shouldn't walk home alone, waking up naked in the clutches of a hairy, bespectacled older man who collars her, leashes her, and mocks everything from her braless chest to her tear-streaked face. What starts as brutal domination—slaps, nosebleeds, and forced deepthroat while he growls that he'll break her arm if she screams—slowly curdles into something worse, as the sobbing captive with ring-pierced nipples is trained into a tail-plugged pet who whimpers that her master's semen tastes very good. A grimy, relentless confinement nightmare where the only way out is through complete surrender.
