My current girlfriend is an S-type girl, and when we go out on a date, she plays with my nipples and dick when no one is looking, but she never lets me cum, and continues the date as if she enjoys my rock hard erection. After being teased to the point of orgasm in the car, at a bar toilet, and in an empty garage, I finally thought I could cum when we got home, but she doesn't stop, cumming once, twice, three times, four times... This time she cums so much that my dick goes numb! I was relieved that it was finally over after she milked me with all kinds of positions, but then she cums again while washing my dick in the bath.
