Trick to avoid pregnancy

Life had gotten a lot better now that our kid had started sleeping through the night. We've been getting full nights of sleep which is a game changer since we both work. Best of all, my wife's libido came back even stronger than before.

We were laying in bed one night enjoying our post orgasm glows when we started talking about how we don't want anymore kids now that things were good.

"Maybe you should just kick me in the balls before we have sex next time. That would make it impossible to get pregnant, right?" I was joking and she laughed, but my cock twitched at saying those words to her. We'd never discussed this kink of mine, so this was the first mention of it - joking or not.

Nothing more came from that conversation, and we continued with our lives. The weekend finally came and we had nearby family that offered to take our kid which they often do.

Saturday mornings are our time to relax. I hopped in the shower to get ready for the day. We hadn't had sex since our conversation 2 weeks ago which was the longest gap we've had in quite some time. I debated jerking off in the shower since my balls were so full, but decided against it. And boy am I glad I didn't.

After I was clean I stood in the shower for a few minutes with the steaming hot water running down my body. I stepped out and wrapped a towel around my waist when my jaw dropped. My wife walked in wearing a sheer satin robe opened in the front with no bra and a pair of sexy panties. I couldn't take my eyes off her swaying tits as she sauntered over to me, dropping her robe on the floor in the process, and gave me a passionate kiss.

"Thank God I didn't jerk off," I thought she pulled down my towel making my rock hard cock spring into action. She put her hands around my testicles which were hanging low from the hot shower and lowered herself to her knees to take my cock into her mouth.

After maybe a minute of going down on me she stopped. Maybe she could tell I was nearing an orgasm and didn't want it to be this quick? All I knew was that I had to have her.

She stood up with my cock in her hand staring deep into my eyes with a sly grin on her face.

"I think you were right, maybe we should try it."

Confused, I started to ask, "what do you..."

SPLAT

I heard the sound before the pain hit me. A full smile was now on her face as she continued eye contact with her knee buried in my groin. As my hands here making their way to my balls and my body was lowering to the floor involuntarily she drew her leg back and kneed me in the nuts once more.

The pain was excruciating as I curled up on the floor and my wife bent down to console me, rubbing my back.

"You were absolutely right about this plan, and if you refuse to wear a condom than this will be how it works."

"Plus, I started thinking about some comments you've made over the years and I began to wonder if you were into getting hit... there."

"It looks like I was right," she said pointing at my dick which was impossibly hard.

Then she asked me directly with a huge smile, "you DO like it, don't you?"

All I could do was nod yes. The pain was unbearable but I had hoped for this exact scenario for years.

Then she grabbed my nuts with one hand and pulled me up until I was standing, the pain increasing as she squeezed.

"Let's go see if you were right, or if I need to beat your balls to a pulp so they never work again!"

We proceeded to have the best sex of our lives, and with the different positions she found ways to grab, punch, or otherwise continue beating on my balls.

Finally, I was almost at the end and I was in heaven. She was on top of me in reverse cowgirl leaning backwards so I could hold on to her tits.

She must have sensed I was about to cum because she leaned forward and raised her fist in the air. My first squirt inside her and she dropped that fist as hard as she could and punched me square in the nuts. The mix of pain and pressure was like nothing I'd felt before as she continued to punish my aching balls with alternating fists until she tired herself out.

She laid down next to me and put her hand tenderly on my chest and held me as the pleasure subsided and the pain crept up my stomach. We were both panting and worn out, but there was a new bond that had formed. We were both looking forward to more in the future.

And the plan did work after all.

I love this woman.
