"You're so stiff... so cute..." -- On a scorching hot night on a business trip, he unexpectedly shares a room with his gentle and sexy married boss. The virgin's eyes are glued to her sweaty, beautiful big breasts and soft, fragrant sex appeal. His tensed rationality crumbles as she defenselessly loosens her chest and gently teases him. "Is this your first time? It's okay, I'll teach you everything," she whispers sweetly, wrapping her soft flesh around him and slowly, thoroughly teaching him the pleasures of life. A blissful night in which the calmness and maternal caresses of an older woman melt both body and soul -- the ultimate reward sex, with Kashiwagi Fumika accepting everything.
