So when I was 16 (now I'm 26). I had a co- worker is was extremely attractive, and she had quite a nice ass. But at the time she was 19( which sucked because I always got a strong vibe she was attracted too me). But she would always come into work wearing these tight black jeans, that really made her ass stand out. So to make a long story short I would constantly try to accidentally rub my d*** against her, and I did. She never noticed (or she might have). I'm not proud of it, but she has an incredible ass.
