Witnessed my friend engaging in sexual activity with customers in the shower

I stumbled upon my friend getting it on with a couple of customers in the shower. It was a wild, taboo group sex situation, and I couldn't help but get drawn into it.

I was in the shower with my best friend when I noticed that she was getting up close and personal with these random customers. I couldn't believe what I was seeing, it was like she was a total slut, or maybe even a pervert. It was a sight to behold, and I couldn't help but snap some pictures of her in action. The customers were totally into it, and my friend was giving them the time of their lives. It was a crazy experience, and I couldn't stop myself from being a little bit turned on by it all. But at the same time, I knew it was totally wrong. I mean, what kind of friend was she? She was basically fucking in the shower with strangers! It was a weird feeling, kind of like I was part of a group sex thing, but without any of the fun. I don't know, maybe I'm just a pervert too.
