YST-226 My colleague's wife will be my personal meat toilet for the next three days, Tsukasa Nagano

A man who suddenly appeared while her husband was on a business trip. It was a man who was also her husband's colleague and who had worked together before marriage. There was talk of her getting married, but apparently she's getting married soon. However, the colleague's man had no confidence in the night's activities, and he said with a straight face that he wanted to practice using Tsukasa's body. Of course, Tsukasa refuses with all her might, but when she is feather touched and kissed, her expression gradually becomes female.
