Part 1 I found Leonie

I was bored. It was Sunday morning and I had a bad hangover. I (M/32) was lying in bed in the guest room and playing with my cell phone. I wanted to watch some porn and jerk off, I often did that when I was hungover. I was engaged and didn't actually have to watch porn because my fiancé always felt like having sex; we've been together for 9 years. I searched a bit for some nice porn on the internet, I like anal and gangbang films. But what interests me most is ballbusting. I've never talked to my fiancée about it, but I think it's cool. My fiancée (F/27) is a great woman, we've had a break in our relationship twice because I just can't stop chasing other women. But that's another matter. Right now she's mad at me because I came home at 5am like a drunk piece of shit. That's why I'm in the guest room.

I found a nice flick online, a guy getting kicked in the balls by two blonde women with bigger breasts in skimpy outfits. When I was finished, I surfed the net a bit. I found the site “Erotik.markt” where all kinds of people offer all kinds of services. I browse through a bit and set filters. Some people really do anything for money. I get curious and look for my fetish. Yes, there were a few crazy people who wanted to turn a man into a eunuch and so on... well, I adjusted the filters a little less sharply. As I was browsing through it, one ad in particular caught my eye: “Do you want to let me torture your balls while you jerk off?” Maybe I'll jerk you off too. Leonie".
The ad had no pictures, but it still made me curious.

I was tired and wanted to sleep some more, which I do. The week started well, everything was going great at work. I couldn't get this ad out of my head. On Wednesday I wrote: “Hey, I’d like to take a look at your offer.” It took three days until I got the answer: “Hey ho, send me a few photos of you, I’ll then decide whether it’s suitable. How old are you?"
I thought damn. I'm tall, but not exactly slim or athletic. I weigh 130kg and am 190cm. Not trained at all. I can score points with women through my appearance and manner, rather than through photos. I thought it didn't matter and didn't write back.
A day later another message came: I'm still waiting for your photos. Send them to me.

Well I took photos and sent them with a short message and my age. 2 days no answer. Then came: All right, next week on Wednesday at my address. Arrive at 7 p.m. and please be on time.

I was curious, also about the direct nature of the message, but also thought, hopefully this isn't an old or fat woman. I had absolutely no idea what I would be dealing with. The time until Wednesday stretched like chewing gum. I left early enough and rang the doorbell at the address given at exactly 7 p.m. It was a typical tenement block in our town. The door opened and I was amazed. Standing in front of me was a very slim brunette who was about 155cm tall and had hair that reached down to her bottom. She was very athletic and had about a B cup. She was a dream and saw immediately that I was thinking exactly that. She grinned and held out her hand to me: “hey, I’m Leonie. “Don’t you want to come in?” I extended my hand and shook it, then walked in. I looked around her apartment at a glance, living room, kitchen, bedroom and bathroom. Approx. 60sqm. Nicely decorated. She went into the kitchen and sat us down at the kitchen table. We started talking and introduced each other. Leonie is a 30-year-old assistant doctor and works a lot, she doesn't like children and likes to drink more than is good for her. She likes sports and said: “I like strong men like you, that's why we're sitting here now. We still need to talk about what we expect from each other." I said openly that I was engaged and that I was bored with sex. I'm looking for something more exciting and maybe some experimentation with my testicles. She looks me straight in the face in disbelief. I thought she would throw me out immediately, even though we actually get along well. “You mean ballbusting” she said. I nod and then we are silent for about 30 seconds. Uncomfortable I think.
Then she says, “get up.” I thought great, now you can go. You should have asked what she wanted, then you might have still seen this beautiful woman naked, I think. I stand up and say: “Listen Leonie…” I didn’t get any further, she slammed her foot into my crotch unannounced. I fell like a wet sack. She laughed: “You probably thought I was going to throw you out. Haha. No, I've been looking for a strong man who I can spank for a long time. I just haven't found one yet. I find it very cool. Hopefully you keep your promises. I'm up for it. When you're done whining, take off your pants." I took off my pants and immediately had a boner. “Beautiful black,” she said. “Lie on your back” I’m coming to you. I didn't need to be told that twice. “What do you think of the safe word “cinnamon stick?” she asked. “Sounds good,” I said. She took off her top and bra. I was rock hard, she looked stunning. She joined me on the floor, lightly stroking my cock. It was great. This is off to a good start, I thought. She looked sweetly in my face, "Listen, before we get started here, we need to talk about some ground rules." 1: you do exactly what I say, I won't tolerate repeating words. 2: we only meet here in my apartment. If we happen to see each other outside, we don't know each other.
3: I'll break your balls at the beginning of our meetings, then we'll get it done. The intensity of both will increase.

Are you okay with that?”
She was still stroking my cock.

“I agree,” I said. "Good. “Then let’s take off all our clothes,” she said.
Said and done. We were naked and I was still on my back. She sat on my thigh, took my testicles in one hand, balled the other into a fist and started lightly hitting my testicles. They were very light blows. It was a pleasant slight pain, it felt great. “How is that?” she asked.
“Hot” I moaned. “Good, I’m going to hit harder now. I feel like beating the shit out of you.” she hit a little harder. It hurt more, but was still pleasant. I notice that Leonie is getting wet. She hits even harder. I say: “It hurts a lot now.” “Good, that’s fine.” She hits harder and harder and I get more and more pain. I start to squirm and move my hands towards my crotch. "Hands off. And hold still. Or should I tie you up? The best thing to do is put your hands under your bottom.” I do that and she hits harder again. Always tighter. It hurts extremely. I lie on my hands and watch as she hits my balls with increasing pleasure. My poor balls, I thought. Suddenly she stops. She slides her body onto mine so far that she can knee me in the balls while lying down. She does that too. It hurt incredibly. I rolled onto my side and heard her laugh. “Turn over on your back again. We're doing something different now. After I have the pain somewhat under control, I lie back on my back. “She says you lick me now and I'll squeeze your balls. So go ahead.” with these words she sat on my face and I licked like crazy. Thank God she came really quickly, she spasmed all over and squeezed my testicles quite hard. When she was finished she said: “Very good, it could work with both of us. Now it’s your turn.” She started to give me head. It was incredibly hot. I came down her throat. I was satisfied and the previous pain was forgotten. After recovering from our orgasms, we got dressed. We chatted some more and I learned something more about Leonie and she learned something about me. To say goodbye, she kissed me on the cheek and gave me a piece of paper with her phone number. She said goodbye to me: “Thank you for the nice evening and see you next time, strong man, I hope to see you again soon.”

I was looking forward to the next time, but wouldn't come again for another two weeks.
