I Set my Girlfriend up to Cheat on Me

Hello,

This all happened last year.

I often meet with my best friend in his apartment to gamble or chill. Since we were 18, not a week goes by without us hanging out together. I've been in a relationship for 2 years now and I've been taking my girlfriend to his place ever since. At some point in a conversation when we were not quite sober he told me how hot he thinks my girlfriend is. I was of the idea that he had something with her, but I didn't tell him. The more we were with him, the more I wanted him to have sex with her.

At some point I casually started telling my girlfriend what a great man my buddy is. I let him stand there in a good light, that according to other women he is incredibly good in bed. Once we were together at sports and I saw in the shower that he is also very well equipped. I also told this to my girlfriend, which apparently aroused her great interest.

She kept giggling and asked me to describe to her exactly how he looked like underneath and exactly how big his penis is. It was really big indeed. In the flaccid state it was already about 18cm long and was also a large piece wider than mine.

When I noticed how interested my girlfriend seemed to be, I really wanted her to sleep with him. Therefore I often sent her to him alone under different pretexts. For example to pick up something I had left at his place or to bring him something of mine. You have to know that she works in the same town where he lives. So she was with him a few times but unfortunately nothing ever happened.

So I casually told her that my friend mentioned that he found her incredibly attractive. She also found this very interesting and wanted to know the exact wording from me. Again I sent her to him several times under an excuse. It was now summer and she was usually very sexy and scantily dressed. But again nothing happened until she told me that she had seen the imprint of his penis through the sweatpants during a visit and that he really has such a big penis as I had described. So I told my boyfriend that my girlfriend saw the imprint of his penis and she became so horny at the sight that she wanted to have sex with me as soon as she got home.

A few days passed and I sent my girlfriend back to him. But this time it was different. She came home later than usual. When she got home she didn't want to give me a kiss but said that she needed a shower now. That made me curious so I sneaked into the bathroom without her noticing and picked up her panties from the floor.

What I discovered made me horny like never before. Her panties were wet and smelled like sperm. It had finally happened. She was cheating on me with my best friend. I kept my discovery to myself and didn't let on. Over the next few weeks I didn't send her to my friend's house because I didn't need to. My girlfriend suddenly worked "overtime" on some days or stayed overnight at a "girlfriend's" from time to time, which she never did before. I kept everything to myself and let the fantasy of her having sex with him run free.

One day, when we were back at my friend's place, I went to the toilet. They had a movie playing pretty loud, so they didn't notice I was coming back. I caught her stroking his penis with her hand on his pants and kissing him. When they noticed me they were visibly frightened and tried to explain themselves. I confessed to them that I knew about it from the beginning and that the idea of the two made me horny.

At first they did not know how to react. But when they noticed that I meant it seriously and said that they can continue with pleasure they did not let me ask them twice. She pulled his pants down and his 22cm long stiff penis came out. She grabbed him with both hands and started to lick his glans. First only the tip, later she took him almost 75% in her mouth. I could see him squirt into her mouth and she swallowed his load. By this time I had already started masturbating myself and came at about the same time as he did.
