Harumi's Bad Play

I want to be your toy... You can do anything... to me! Wataru is a guy next door. One day he saw a little innocent girl in his room. Her name is Harumi. She asked Wataru if she could stay with him. She didnt have anywhere to go. Because of her innocence, she doesnt know anything about a mans body and even her own. Wataru shows her his pet (his cock). She loves his cock so much that she starts to play with it. Wataru cant' hold his out anymore, so he has sex with her without telling her the truth. At the end, he will unravel the truth behind Harumi!
