SSIS-555 A dreamy overnight hot spring affair trip with a mistress who is the best in both looks and sex

A lover who is a circle younger than my wife, with tight and smooth skin, a good temper, and no fights. Rarely able to meet, we crave each other madly when we do. A voracious sex drive... she helps me regain the youth and smiles I had forgotten. We spend a night and a day in a hot spring, fucking like crazy. She'll tease me with mean words like 'You won't tell your wife to leave you, will you?' But then, in an instant kiss, her expression changes completely into that of a mature woman... why is it that the harder something is to obtain, the more we want it?
