My wife is on her way home from birth. Miho, her daughter-in-law's older sister, came because it would be inconvenient for a man alone. The man gratefully accepts his sister-in-law's kindness, but...

Miho's temptations are so erotic and sensual that she easily shakes her mind when a man says he can't betray her wife.
