I got chatting to a security guard on Grindr and agreed that when he finished work he would come over. I was dressed in a skimpy schoolgirl outfit with thigh high socks and a wig in pigtails. No panties, but I was wearing a cute pink chastity cage. When he got here we got straight to it. I started sucking him and initially thought he wasn’t that big but boy did he grow, to the point I was gagging. I then straddled him and slowly lowered myself onto his cock. It was a big stretch as I’m very tight but we took it real slow. When I was comfortable I started riding him for a bit until he got impatient and began fucking me from below. We switched positions and he then pounded me into the bed and it didn’t take long for him to come. I reckon this guy was twice my weight and 2ft taller than me. It was so hot being used by him!!
