Rei Aino and Nao Kiritani are pushed into new realms of pleasure in this intense, tension-filled training session. Bound tightly with hemp rope, their bodies are completely restrained, leaving them at the mercy of their male dominators. Their skin reddens under the constricting ropes as they gasp from deep-throat stimulation. Even as they repeatedly reach orgasm, the relentless toy play never stops. Through pain and suffering, true pleasure is seared into their bodies—until ecstasy spreads across their twisted, overwhelmed expressions.
