3 years of marriage, husband is a salaryman. At first glance, they are a normal couple, but the bride Serina is dissatisfied with her husband's propensity. Until I got married, I didn't have sex and it was only a fucking relationship, but even after I got married, my husband only had a fucking. I will discuss this with my brother-in-law and try to find a solution. On the other hand, the other lazy brother-in-law is a good-looking guy who likes his sister-in-law, and immediately becomes a sex friend. How is the sexual relationship between the brothers and sisters? !
