Yuto Kuroda, a stern educator, seizes the opportunity to teach Rien Tachibana, a curious student, the art of deep kissing and armpit fetish. As she tentatively presses her lips to his, he guides her tongue, deepening the kiss. Her slim waist arches towards him, seeking more. Yuto, aroused by her slimthick figure and average-size tits, can't resist. He spins her around, pushing her against the desk, her average height perfectly aligned for a hard, deep fuck. He rams into her, his thick cock stretching her tight pussy. She gasps, her straight hair flying as she grinds back, eager to learn every thrust.
