Tired of the daily grind and worn out from housework and errands, Ai felt a vague sense of emptiness. One day, her air conditioner suddenly broke down, bringing repairman Yamamura to her home. His wild, rugged, and intensely masculine presence stirred something deep inside her. Sensing her unease, Yamamura gently pulled her into his arms. His warmth and the soft kisses trailing down her neck sent shivers through her body. His tongue slowly explored her skin—fingers, armpits, back, legs—covering every inch of her with thick, deep, and intensely pleasurable foreplay. Overwhelmed by sensations she'd never known, Ai discovered a new kind of pleasure, and from that moment on, she continued to deepen her secret affair with Yamamura.
