Fun for four, I had my first foursome when my roommate brought a couple friends to our apartment [Group] [MFMF]

Hello everyone! My first post here, finally gathered the time and courage to share this here. Some notes before beginning: 1) I changed names because of privacy reasons. 2) Everyone in this story is between 21 and 24 years old at the time this happened.

When I started university I moved to another city. I found a nice apartment near university, however I needed to find a roommate because it was too big and expensive for me to afford it. I heard that the older brother of a long time friend was looking for a place while he did his Master. We contacted and he moved in. His name was Charles. He was a STEM student. He was a bit nerdy like me but he liked to party more than I did. When he arrived we talked about bringing friends or girls to the house. He told that me he usually doesn’t brings girls to sleep with him so that wasn’t going to be a problem. That wasn’t entirely true. And this story explains one of the many times he showed me the opposite.
