Hard knee to the balls from my wife last night

Last week was busy in my house. My wife and I didn’t see each other much and we went the entire week without sex which is rare for us. She also hasn’t busted me in a while. I’m not sure about you all but when it’s been a few weeks my balls are extra sensitive. It almost feels like getting kicked for the first time all over again.

Last night she was in our bathroom and when she came out into our bedroom she had nothing on but a t shirt. Being pretty horny I walked over and pushed her against the door frame while kissing her and feeling her breasts and ass. She sort of giggled and asked what I was trying to do so I asked her if she could hurt me a bit.

Of course she said yes and told me to stand with my legs spread a bit on our bed. Usually she’ll do a practice swing or two before kicking or grab my shoulders before kneeing me. I was surprised when she stepped up on the bed and immediately threw her knee right into my balls. It was a very hard knee. At least three times harder than I was expecting. Before she could even withdraw her leg I was at her feet cupping my balls while struggling to catch my breath.

I think she felt bad for kneeing me so hard because she sat down next to me with a worried look on her face. At that point my legs were involuntarily thrashing back and forth and I was making pathetic moaning noises. Then she slapped my ass really hard and laughed while telling me I asked for it. She stood up and placed her foot on my side while lifting her arms up in a victory pose.

10 or so minutes later I was eventually able to get up and fuck her but damn, my balls are still aching 18 hours later.
