Ai, whose husband is away on a business trip and has no sex with him, is entrusted with her nephew by her sister. The nephew is a total nerd and when he comes home he ignores Ai and starts studying. His attitude gets the former slut going and she seduces him. At first he ignores her but she succeeds in getting him to erect (huge cock)! Then late at night, she reverse rapes him and takes his virginity... but her first sex makes her libido explode! She's not satisfied with just one time and even though she runs out of condoms, she forces him to have sex raw, and when Ai tries to escape, she holds him with his cock still inside and cums inside him over and over again!
