Let me introduce my sex friend. Serina is a freeter who usually works part-time at a restaurant. She sometimes meets me, even though I'm an older man, and gets money and pleasure before going home. She's a natural bitch who would rather go straight to the hotel than have a nice meal, but she seems to be addicted to the techniques of middle-aged men, and doesn't want any younger men anymore, so today she's begging me for a raw dick.
