Being touched by a stranger at a concert

Heya I am 21 F and a college student. This happened at the start of January, when I went to a pretty famous Indian singers concert. I was with a 2 friends and one of their boyfriends. I started to feel a touch on my ass. I had a small skirt on with shorts under and a black corset top. It was super light and nothing serious but I was so horny so I backed up a bit. I wanted the attention. And slowly we started dancing. I still hadn’t seen his face, which made it even more fun. He then wrapped his hands around my waist completely pressing his crotch against my ass cheeks. I looked up and saw he was definitely not my type but I didn’t care. My friend wasn’t feeling well so we were planning to leave and I told the guy this. He told me to start asking for my number etc. But I really didn’t want to. We planned to leave in around 10 mins and during this I took his left hand and placed it on my left boob. I knew he was gonna grope it but not to the point where he’s found my nipple and he is completely playing with it. I could tell he was an amateur but that made it way more hot.
