The classroom's hushed atmosphere is shattered as the door creaks open to reveal a disheveled, panting teacher, Aina Reminen. Her eyes, wild with desire, scan the row of innocent girls, their uniform tops straining against their burgeoning breasts. She commands them to undress, revealing smooth, unblemished skin and heaving mounds that quiver with every breath. Aina's hands, trembling with anticipation, caress the girls' naked flesh, pinching nipples to hard peaks. She guides their hands to their own wetness, teaching them the rhythm of pleasure. As the girls moan in unison, Aina strips, her massive tits spilling free. She mounts the nearest desk, spreading her legs wide, inviting the first volunteer to fill her with his virgin cock.
