With the right warm-up, you can take more than you thought you could.
A few weeks ago, at a play party, a switch I know asked if we could do a spanking scene. We negotiated a bit, and during the negotiation she said that she is a light bottom. Which is totally fine, but she also knows that I can (and do) play hard. The thing is, I don’t have to play hard — I have one partner who is also a lighter bottom, and we have very successful spanking scenes together. So while I told this person that I would not go crazy on her backside, I did tell her that she could probably take more than she thought she could.
And she did.
I used mostly my hand, warming her up with light-to-firm spanks, turning her pink, and then increased the intensity to fully-firm, peppering in some harder ones as I went, just to keep her on her toes. We did that for a long time, until I was sure she was ready for moderate spanks. I also paddled her a bit with two different paddles, including my “evil stick”, which is great for getting that spot right at the base of the cheeks.

But ultimately I was having too much fun just spanking this person with my hand, so I went back to doing that. She was on a spanking bench, and for the last few swats — which were very hard — I knelt beside her and put my arm around her waist to hold her in place. Not that she was moving around a lot, but it’s the mental side of things that I was going for here.
When I was done, she had a couple of spots on her bottom that looked like they might bruise a little. And yet she claimed to be a lighter bottom. But with the right warm-up, she took a lot more than she thought she could.
Let that be a lesson to both tops and bottoms. Tops: warm up your bottoms (unless you’re punishing them, or they don’t want to be warmed up). Bottoms: trust your tops to warm you up before they go harder on you. Both of you will enjoy the spankings a lot more.
