Yui wasn't satisfied with her night life. I was rejected because my husband was tired today. At that time, my husband's brother will come to stay for a few days. To tell the truth, my brother-in-law is not good at it, so please refrain from doing so, but I decided to accept my brother-in-law because I wanted to be considered a wife who could do it. On the day of the event, his brother-in-law, who is still masculine, is fascinated by the appearance of the bath. Yes, the crotch is strangely big. Until now, I hadn't thought about it at all, but Yui, who noticed a sense of discomfort in her crotch, was really worried about her brother-in-law. Coupled with recent frustration, a nasty delusion has swelled. Yui, who encountered a situation where her husband went out and her brother-in-law was sleeping, wanted to actually see her brother-in-law's crotch, so she secretly shifted her pants. My brother-in-law is getting bigger while I'm stuck. Yui was staring at a close distance while holding her crotch. When I noticed, I was sucking my brother-in-law's thing with all my heart while drooling.
