Kaia Martin wants to have a child, but not with her husband. She's long noticed how smart and clever her husband's brother is. The only problem is that he is an insecure nerd who is incapable of bonding with a woman. But she knows how to play the role of a good sister-in-law and it won't take much to convince him to inseminate her and pass on his privileged genes. This guy has never cum inside a woman before, so the offer is not to be refused. He's going to make a creampie for his hot sister-in-law!
