I told my girlfriend I loved her on the phone while I was cumming inside her best friend

First of all, I would like to say that I am French, that my English is not perfect, but that I will try my best. So I apologize for any mistakes there may be in my text...

It was my girlfriend's birthday party, we were all gathered in a bar, and it was the first time I had met her childhood friends. The evening was going pretty well, even though I was very tired and quickly became a little drunk.

As I went outside to smoke, one of her friends came with me. She was a cute little alt girl, and we talked about this and that, and then I don't remember exactly how it came up, but she told me about her black lipstick, which unfortunately doesn't stay on very well.

Without thinking too much about it, drunk as I was, I replied that I would be very curious to see her demonstrate. A few seconds later, we were kissing in an alleyway right next to the bar.

We didn't say much at the time, but it was obvious to both of us that we wanted more. So I went to see my girlfriend, telling her that I was going to quickly stop by the apartment to take a shower and change (I had just left work when I joined them), and she made up some excuse that I can't remember to say that she was going back to the Airbnb she had booked for the weekend.

I waited for him in the alley where we kissed, and we headed to my apartment, which was right next door. Once the door was closed, there was no discussion, no hesitation, no regrets. As if saying anything would break the moment and make us realize what we were doing and how wrong it was.

So I threw her onto the bed, lifted her skirt, and without thinking (once again) ripped her fishnet stockings. I undid my belt, then my pants and my boxers. I started rubbing myself against her thong, still without saying a word.

She let me do it without saying anything, staring at the ceiling and moaning as if looking me in the eyes would ruin the moment. Then, without saying a word, she shifted her thong to the side. There was a brief pause, but it was already too late, I was already inside her.

Not a word was exchanged, just the silence of our bodies pressed against each other and our racing breaths. It lasted a little while; honestly, I lost track of time. When suddenly my phone started vibrating, my girlfriend was calling me.

Without stopping, I picked up the phone. On the other end, she was crying, worried that her best friend still hadn't returned. She was afraid that something had happened to her, as she hadn't heard from her since she left.

I tried to reassure her as best I could, saying that everything was fine and that she would surely come back. When the person in front of me started convulsing, one hand over her mouth.

At that moment, I let myself go in my movements, accompanying her in vice until my climax. At the end, I tried to reassure my girlfriend one last time, telling her how much I loved her while I emptied myself into her best friend.

After that, there was a brief moment of uncertainty as we gathered our thoughts. She left before me so I could take a shower. In the meantime, I received a message from my girlfriend saying she had arrived home safely, smiling to herself knowing that my cum must already be running down her thighs...
