Honoka Tsuji went on a hot spring trip with her husband and father-in-law. This trip was suggested by her father-in-law to relieve stress after seeing his two children engrossed in work for a long time, and more importantly, he wanted a grandchild. But heartbreakingly, while Tsuji was excited to be intimate with her husband, he couldn't perform, and she could only suppress her sadness and quietly went to take a bath to get through it. Coincidentally, her father-in-law also went out to bathe and saw Tsuji's wonderful body; her large breasts were so enticing that he could no longer restrain himself.
