Write a story about a guy named NAME_1. He has a sexual fetish for foot fetish anime. He always searches for pictures of anime girls in dirty socks. Than he masturbates. He's using his own smelly socks to masturbate while watching those pictures. Suddenly his girlfriend NAME_2 comes home and sees him. NAME_1 doesn't notice her. She sneaks up on him and suddenly thrusts her foot into NAME_1's butt hole. He is startled but gets an extremely intense orgasm immediately.
