Morishita's sultry voice whispers, "Let's do something we shouldn't." Her companion nods, eager for the taboo. In a cramped, dimly lit classroom, they begin. Karin's skilled fingers unzip his pants, releasing his hard cock. She strokes it gently, her eyes never leaving his. She leans in, her tongue flickering out to taste him. He groans, his hands tangling in her hair. Karin takes him deep, her head moving in a steady rhythm. She loves the feel of him against her tongue, the taste of his pre-cum. He responds, his hips moving in sync with her mouth. Their secret encounter intensifies, their passion fueling their forbidden act.
