I think my boyfriend is unfaithful

For a while, I had doubts about whether my boyfriend was being faithful to me, and I decided to put him to the test. I had noticed that when he drank, he seemed to be less restrained in flirting with others.

That Saturday, we were having a drink, and it was already 3 am, and my boyfriend was drunk. I was a bit drunk too, and I think that's why it didn't take me much effort to suggest going to a sauna to take a look, but with no intention of doing anything.

Curiously, he didn't seem surprised, and he told me, "Let's see what we can find." We arrived, took off our clothes, and put on a towel. From there, we went for a walk. There were quite a few people, but nothing out of the ordinary.

My boyfriend suggested going to the jacuzzi, and I said it was a great idea. We got in, and there was an old man and two guys fooling around inside. We sat down on the side, relaxing. Not much time passed before a strong, muscular guy with some body hair and a tough face arrived. He must have been around 40 years old.

He sat down in front of us, and I realized that my boyfriend and he started checking each other out. Before I knew it, they were playing with their legs under the water. The guy had stretched out his leg and had it between my boyfriend's legs, and he hadn't said a word.

Not much time passed before my boyfriend told me he was going to the bathroom and asked me to wait. It didn't take long before the guy stood up with a hard cock, trying to cover it with his hands. I was left paralyzed, not knowing what to do. It seemed like everything was leading up to him fucking my boyfriend.

I felt frustrated and, at the same time, pleased - it was a strange feeling. The humiliation was turning me on, knowing that my boyfriend's ass was being ravaged by a real man, and not by me, who couldn't help but be a submissive bottom trying to be a top.

I got up and ran after them, almost losing them because I had waited too long and they had already gotten out of the water with their cocks hard.

I managed to see the guy enter a cabin, and just as he closed the door, I was left standing there, not knowing what to do. I called out, but they didn't open up, so I went into the next cabin. I put my ear against the wall and couldn't hear anything at first, but then I started to hear moaning, and I knew it was my boyfriend. I began to feel frustrated until I heard, "You're going to split me in two!"

I don't know how, but my cock started getting hard... "You're going to break my ass... Oh yes... Give me more cock!!"

I crouched down to try to see something through the gap between the wall and the floor, and I saw the guy's sandals and feet. I leaned in further, and in the mirror, I could see my boyfriend on all fours, taking it.

I started to get wet on the floor and jerked off like a madman. My boyfriend's ass was being ravaged by a huge cock that seemed to be deeper inside him than I ha...
