In the stuffy university library, a curious student can't resist the allure of his classmate's heaving cleavage. He leans in, his breath hot on her skin, and tentatively traces the outline of her bra with his tongue. She gasps, but doesn't pull away, her nipples hardening at his touch. He grows bolder, unbuttoning her shirt to reveal her lacy bra, and teasingly licks around her areolas before finally taking her erect nipple into his mouth.
