Self-proclaimed "heart's lover of housewives" AV director Koichi Takahashi invites his wife's female friend to stay at his home with ulterior motives. There's no way nothing would happen to a housewife spending a night alone with him... Wakako, 32 years old, married for 8 years, works in medical administration. After mentioning that there is a custom of wearing masks for free sex at an old festival in her husband's hometown, the housewife accepts a proposal to put it into practice. He fondles the masked housewife's body, making her breath ragged, followed by a wet blowjob praised for its lewd licking technique. When his cock is inserted, she spontaneously pulls her knees up, inviting him deep inside and writhing in ecstasy. In the middle of the night, she shyly laughs after leaking while climaxing from a toy. The next morning, she sucks his cock, and as he pounds her from behind, she moans rhythmically.
