My younger sister is preparing to get married to a mature, mature, tall man, my standard type. I am very jealous of my younger sister when she is lucky to be the wife of him instead of me. Every time I see him, my sexual desire for him rises, it is extremely strong because I have not had a lover for a long time. I decided to express this desire to him before he married my younger sister and even threatened not to attend the wedding if he did not agree. As a result, the night before the big day, they had a lot of sex everywhere in the house.
