[The adora-bitch diaries] My wife's muscle memory vs. my tender balls

I'm Quinn, early 30s, married to Katie. I've been writing down our kink experiences because our sex life has gotten absurdly good and I don't want to forget the details. She's a playful, naturally sadistic femdom who I lovingly think of as my adora-bitch. I wrote a full intro post [here](https://reddit.com/user/QuinnteractiveR/comments/1r04z38/intro_the_adorabitch_diaries_my_wife_evolved_into/) if you want the backstory, but this one's short and sweet.

So I got a vasectomy. I was on the younger side for it but had my reasons. Recovery wasn't terrible, honestly. Sore, tender, the usual. Doctor said no sex for two weeks, and I'm a rule-follower when it comes to my balls, so we stuck to it. Which meant two weeks of me going down on Katie, getting her off, and then just... existing. No jerking off, no cumming, nothing. She thought this was the funniest thing in the world. She'd pat me on the head after I finished eating her out and say "you're doing so great, sweetie" in the most patronizing voice imaginable. Love of my life.

Katie and I have a ballbusting thing. Regular part of our play. She's not the type to randomly kick me in the nuts while I'm doing the dishes. It's more like she'll work it into a scene, start light, build up, read my reactions, and escalate until I'm squirming and whimpering and trying to close my legs, except oh wait, they're tied open so I just have to take it. She's good at it. She knows exactly where the line is between "fuck that hurts but don't stop" and "okay we need to pause." Practically muscle memory at this point, which is why what happened next was so perfectly her.

The two weeks are finally up. We'd been flirting all day, joking about how pent up I was. We get to the bedroom, start making out. I'm on my back, she's on her side leaning over me, tongue in my mouth, hand on my chest, things heating up fast.

THWACK. Full open-palm smack, right on my balls. Not a love tap. A real hit. The kind she'd throw on any normal Friday night when she's trying to make me yelp.

My eyes went wide and I made a noise that shouldn't come out of a person. Two weeks post-vasectomy, your balls are still tender. Bump-them-getting-out-of-a-chair-and-wince tender. And she just smacked them like nothing had happened.

I looked at her and she had the grin. That smug "I got you so good" grin she gets after a clean hit. It lasted about one second. Then I watched it happen in real time. Her eyes went from smug to wide. Her mouth opened. You could see the thought cross her face: *oh. Oh no. Oh fuck, his balls.* The grin cracked in half into something between horror and laughter. She slapped her hand over her mouth, whole body shaking, trying not to laugh while processing that she'd just walloped her husband's freshly-operated-on nuts.

I groaned, rolled onto my side, cupped myself, and lay there breathing through it. "Why," I said into the pillow. She lost it. Full hysterical laughter while rubbing my back and saying "I'm sorry, I'm sorry, I'm so sorry, oh my god I can't believe I did that, are you okay, I'm so sorry" all in one breath.

Honestly, once the pain faded and I could think again, part of me was already filing it away as hot. Being hit when you're that vulnerable, even if it was pure autopilot this time. The fact that her instincts are so wired to bust my balls that she forgot about a whole surgical procedure is kind of the most flattering thing that's ever happened to me.

We still had sex that night, after I recovered. It was worth the wait, but god *damn*!
