This is from last summer. There was this girl, with whom we had a kind of a BDSM relationship thing going (Dominant/submissive).
So one night, at quite a late time, we went to the park. It was really quiet, but still the thought of getting caught was exciting. I stripped her naked and tied her on a tree, her back facing me at first. I had the whip I usually used with me, but I thought it would be better to just spank her using a branch. We were both overachievers and it seemed a good idea haha. So, I started spanking (or whipping?) her with a branch, while she counted every blow, thanking me after each one. If she would make a mistake, I would start all over. She did make some mistakes so the total count was a lot! After I was done, her ass and back were red and stinging in the most pleasurable way. Pain was never an issue with her
After that, I untied her, got her on her knees and tied her hands on the tree, above her head. I also tied her torso, so that she could not move. Which led to oral play. Of course, during all that verbal humiliation was happening.
