My current sex partner has been telling me his fantasies and his top two right now are public sex and inflicting pleasurable pain. We decided to explore both of these today by playing hooky from work and going to starved rock state park. The plan was for him to pull my pants down and bend me over on the trail around one of the canyons we like, give me an anal creampie, put a butt plug in and watch me suffer walking back. Context: not sure if this is everyone, but whenever someone cums in my ass, I have to push the cum out right away or it just feels super uncomfortable. Things didn't go according to plan but were still fun. When we got to the agreed upon canyon, no one was there but we had passed a few people, including an old man and one couple on the way. He leaned me on a rock, pulled my leggings down, but for some reason he couldn't fit inside anally...I think it was just nerves🙈, so instead he roughly inserted himself vaginally and started saying the dirtiest things I have heard in my life (this made me super wet). He grabbed my breasts and was pounding hard and fast. He grabbed my ponytail and at one point, jerking my face up to see that saw that the old man was coming into view, i gasped and I tried to push him off but he pounded harder. I felt my face turn red. The old man nodded at my partner and said something about this making his day and kept on walking. My partner finished inside me as soon as he walked off and pulled me pants up as the couple approached. We kissed and My partner then says "you're such a dirty slut, we should have let him take a turn." I thought about it seriously as we walked back and I think I would have been into the old guy joining ...with a condom 😉.
