Two married lovers slip away alone to a private hot spring for a forbidden affair. Her large breasts contrast beautifully with her slim body, and as a man in his fifties, he revels in touching her skin in her twenties. Seeing her naked at the secluded inn would arouse any man, but the real thrill is that she welcomes both bareback sex and creampies despite being married. Since it may be a long time before they meet again, he plans to fuck her all night.
