Kyoko, who does both work and housework well, has recently been increasing her sexual desire, perhaps due to stress. - My brother-in-law was coming tomorrow, so I invited my husband beforehand, but he refused, saying he was tired. - My brother-in-law is a strong man who works as a farmer in the countryside and is the complete opposite of my husband. - However, Kyoko had a dislike for so-called manly men. - My brother-in-law, as rough as ever, came rushing in, carrying a heavy cardboard box. - Kyoko was irritated by the manly odor that was choking her, but she quickly suggested that he take a bath. - Kyoko felt a little calm after seeing her brother-in-law refreshed after taking a bath, but she noticed the bulge in his crotch that was visible at the edge of her field of vision. - Since I couldn't do it with my husband yesterday, I couldn't take my eyes off that part of my brother-in-law. - The next day, Kyoko encounters her stepbrother in his underwear and witnesses his bulge again. - Kyoko, who was convinced that her brother-in-law's object was big, managed to restrain the sexual desire that welled up from the depths of her body, but she couldn't help but want to check out that object. - When I went to my brother-in-law's room to give him his laundry, he was taking a nap, looking comfortable. - Kyoko suddenly pulled down her panties and saw her brother-in-law's things. She couldn't control herself any longer, and before she knew it, she was rubbing her cheeks against her brother-in-law's things.
