My Path To Becoming A Cuckold Part 1

I met my girlfriend Lisa when I was 20, still a few years younger. Lisa looked really great: 1.65m tall, long brown hair, two wonderful breasts and incredibly long legs. I have no idea why she fell in love with me. I'm also rather short, only 1.76m and only have a small willy. For those who are interested: It measures 8.5cm flaccid, or 18cm X 5.5cm stiff. I actually think it's quite pretty She was still a virgin at the time, unlike me. I had already slept with girls a few times. But these were only one-night stands on the shelf. That's how Lisa and I discovered sex in an incredibly beautiful and playful way. There were no taboos for us and so we tried out everything you can do as a couple and hardly got out of bed. Everything involved a lot of tenderness, but also a lot of fun and curiosity. I think that was the best time of my life. She did say at the very beginning of our relationship that she couldn't imagine having just one man in her life, but I suppressed/ignored that. She was still at school at the time and lived with me. At some point, she had a school trip to Berlin. I also received a letter from her almost every day in which she wrote how much she missed me. But suddenly I stopped getting letters from her. Instead, she called to tell me that she was doing really well but that she needed to talk to me when she got back. Today, my alarm bells would immediately go off, but back then I didn't think anything of it. When she was back with me, I naturally went straight to bed with her and slept with her. As we lay there cuddled up together, she told me the following: She was on the streetcar in Berlin when a guy sat down on the bench with her. He must have looked at her quite conspicuously, which didn't surprise me as she was wearing her favorite pants again. A kind of leggings or gym pants that were very elastic and fit like a second skin. Her long legs and her pussy stood out beautifully in these pants. Suddenly he put his arm around her and kissed her. She must have been quite turned on by the situation, being taken by surprise like that. A stranger who doesn't talk for long and just takes her. And all in public. He then got pretty rough. In the middle of the train, he kneaded her breasts through her T-shirt and also stroked her between her legs, but all with the fabric of her clothes in between. She told me that she was totally turned on by being groped in public like that. A few stops later, the two of them got off the train. They then looked for a dark entrance to the house and carried on there. The guy took off her T-shirt and bra. She said it was a very special thrill to stand half naked in the doorway. He kneaded her breasts and made out with her wildly. Then he pulled her pants down to her knees with her panties. She felt really at his mercy at that moment. This feeling turned her on so much that she also opened her pants and felt for his cock. She said that she couldn't believe what she was finding. Until then, she had thought that all men were equipped in roughly the same way. Until then, she had only known my part. But the guy's cock was much bigger than mine. While she was talking, she started to open my pants and jerk me off slowly. I was confused when I realized that her story was really turning me on. I was totally turned on, but also shocked. She grinned at me and continued. He didn't take long with the foreplay and immediately put his strap on her and slowly penetrated her. Lisa told me that the feeling was incredible. She could really feel him slowly stretching her vagina. She felt really full. It would have been like taking her virginity a second time. - That was right! I was the first and only person she had ever had sex with. My emotional chaos was indescribable. She told me that after he had penetrated her to the hilt, the guy had thrust really hard and that she had come twice when he finally squirted his cum into her pussy. Full of enthusiasm, she told me that he had squirted a lot. He must have squirted 7 to 8 spurts into her. Lisa didn't know that about me either. I only have 3 to 4 squirts when I come. The two of them stayed in their position for some time, he still in her pussy, until his cock slipped out of her limply. When he then pulled his cock out of her, a real gush of his semen came out of her vagina and dripped onto her panties, which were still hanging between her knees. She told him how naked and exposed she still felt. She found this feeling totally exciting. She then put her clothes back on, gave him our address and told him that she wanted to see him again. On the way to the hotel, she noticed how his sperm leaked out of her and soaked her panties and tight pants so much that a wet spot formed in the front. When she arrived at the hotel, she went straight to her room, where a classmate was already sitting. She saw the stain and asked with a grin if my friend had met anyone. Lisa then told her everything in detail. She was probably quite surprised that it was my girlfriend's first experience of this kind. Her friend found this feeling of being "filled" and the amount of sperm quite normal. She said that Lisa must have a pretty puny man at home and started to laugh. Lisa said that she was a bit embarrassed to talk about me and my cock. But after a while she had to smile about it too. She said she felt like a woman for the first time at that moment. Lisa then decided to call me and prepare me for this story. Her classmate stood next to her and laughed her head off. When Lisa had finished her story, I was completely exhausted. I had always thought that I satisfied her completely when we had sex and that I was actually built normally. For some reason, the story and her tender hand around my cock had turned me on so much that I was about to come. However, I was also deeply hurt and jealous at the same time. She realized this and tried to comfort me by telling me that my cock was also quite nice and that it was a one-off thing for her. After a few more questions, she said again that she had always said that one man wasn't enough for her in life. And that if he got in touch, she would want to meet him. The feeling of having a bigger cock inside her was so overwhelming that she really wanted to have it again. When I then wanted to sleep with her, she refused. But she wanted me to jerk off in front of her. She wanted to get a better picture of my cock, she said. I thought that was cool, but also quite humiliating, according to her report. In the days and nights that followed, she didn't want to have sex with me either. But every now and then she would tell me about her experience while I was wanking. I think it was four days later and we hadn't had sex with each other again when the doorbell rang early in the morning. When I opened the door there was a guy I didn't know. He looked pretty torn and asked if Lisa was there...
