My girlfriend is a slut. Help.

Okay, this is a short story that happened to me yesterday. I'd like you to give me your opinion on what happened. My brother is working in Córdoba but he came to visit last weekend and was going to stay at my house because our old man was going away on missions, so it was the first time he would be staying at mine. The thing is that my beautiful girlfriend always sleeps with her red silk pajama or at most a camisole down to the knee. But yesterday morning I woke up when I heard the noise from the door. I opened my eyes and it was my naked girlfriend, with only the top part of her pajama on, which is a tank top. She was about to leave like that.

When she went to the bathroom, I started thinking maybe she came out in a thong and crossed paths with my brother and me sleeping . If she came out of the bathroom and crossed paths with him . Besides, she never wears thongs , just today ???? You guys think it's weird? Thinking about all this got me hot and my cock stood up when she returned. I wanted to give her a huge orgasm, but the idea kept spinning around
