So, I had a wonderful time with a new sub last night. She and I had met at a bdsm party thrown by mutual friends back at Thanksgiving. We saw each other again on New Year's Eve where I saw her take a delicious beating that resulted in some wonderful bruises that only just finished healing this week. Last night was the first time she and I actually hooked up. I hit her ass for quite a while with canes of different diameters, and turned her ass a lovely shade of red. But today, there was hardly any bruising.

So here's my question. How much does her position effect the bruising? When she was being beaten at the NYE party she was kneeling on a chair and resting her weight on the chair back. Last night, she was laying flat on her mattress while I moved around, wielding the canes. I noticed a lot more jiggle to her ass as I was hitting it last night (it was very sexy) than when she was kneeling at NYE. Would that have an effect?

We both enjoyed our time last night, and that is the most important part, but I still enjoy seeing the bruising after a good impact session. I like seeing the visual evidence of our time together.

TLDR: Does kneeling/bending over tighten the skin and make bruising easier than laying flat and relaxing the ass muscles?
