Mark and Jamie had a pretty normal sex life. Both in their late 30s, they were an active, fit, hot couple, Jamie especially. The sex was good; Jamie was somewhat submissive and Mark was slightly dominating and they both seemed satisfied. But there was one very curious aspect: Mark would sometimes ask Jamie to spank his ass. Neither made a big fuss about it. She obliged; it fit right in and that was that for a while. She thought the spanking was a little weird but it was okay. It was never more than a few slaps and then they’d move on. It went that way for a long while.

Until one day. While they were playing around Mark asked for Jamie to spank him again. She heard him loud and clear and they’d done this what seemed like a thousand times, but she told him to repeat it, to ask her again. Mark didn’t realize that something was up, he just thought she didn’t hear him. He was laying face down on the bed and said again, “spank me.” Jamie replied, a little firmer, “say it again.” Now he was a little curious but obliged, himself a little louder, “spank me!”

With that, Jamie smacked her bare hand across his ass harder than she’d ever done so. Hard enough that he noticed a difference, and yelped a little. He started to turn his head up towards her with a bemused look on his face, but she said to him very firmly, “Bury your face and ask me again!” He did as he was told. “Spank me,” he said as he turned his face back down. SMACK came her hand again, harder than the first one. He flinched this time. Before, when they were doing this it stung him in a mild way. This time it was stinging hard.

“Again,” Jamie said, he voice becoming sterner and more demanding.
