I was at mardi gras getting a hand grenade. There was a black girl next to me ...probably in her mid 20s. I place my hand at my side - her back was facing me. I was a bit drunk so I decided to try my luck and I cupped her boot albeit gently; she didn't react. I kept my hand their gently squeezing and then moved to the horizontal cleft under her butt and kept it there; she didn't react. I kept massaging and squeezing her ass all the while I was there. After I got my drink I left although thanks to mardi gras and the rush the drink took quite some time to get there - I didn't really mind it
