OK, let me explain this. Me and this guy are just friends and he already has a girlfriend. So day before yesterday I was working on a boring assignment and he sat with me. We casually talked about many random things and I dropped my pen down, so I bent down to pick it up and in that split second, he grabbed my breast and squeezed it. I had a wtf expression on my face and he walked away smiling. what's with him? Should I continue to be friends with him? Is he a pervert?
