After a fight over trivial matters, Masashi attempts reconciliation sex with his wife who is sulking. He kneads her firm ass and thrusts inside, releasing directly. Feeling an unusually tight grip, he happily forces a kiss... only to find that it was his wife's sister! "I-I'm sorry, sister-in-law!" Masashi apologizes on his knees, but the sister-in-law, who has forgiven him, cannot suppress her stirring body.
