A couples-only hot spring trip. 'Since the kids are adults now, how about a mixed bath?' So off to the mixed bath they went. Then a young man got a full erection at the sight of the wife's huge breasts!! The married woman who noticed couldn't stop herself anymore!! Excited beyond measure by the erect penis that was so different from her husband's, her vagina was soaked. After having sex without her husband's knowledge, she even made him ejaculate inside her—what a perverted wife!!
