I was just chilling minding my own business... maybe I actually was stretching my ass with a massive plug cuz I was bored, while vaping, then he came in and started fucking me so hard the butt plug went in a bit, as soon as he took his dick out the buttplug came out and I started riding him in a different position, at this point I am not paying so much attention to vaping anymore, we continued in the floor, almost in an acrobatic position and at some point he confused the hole and accidentally kept fucking me in the ass, I mean my ass was ready for it after that butt plug went in so it was a really good surprise!
