Two uniformed schoolgirls, Maruta W and Maruta H, are led into a dimly lit room by their stern, unknown teacher. He orders them to strip, their bodies shivering with anticipation and fear. As they stand before him, naked and vulnerable, he commands, "You mustn't move!" Yet, their bodies betray them, nipples hardening, pussies dripping as he runs a thick, calloused finger along their wet folds. He orders them to sit, their tight, untouched vaginas sinking down onto his massive cock. They gasp, their bodies tensing as they struggle to take his entire length. But their lust takes over, and they grind against him, his hot cum filling them both as they collapse, their bodies shaking with post-coital remorse and satisfaction.
