She wanted something new, her first threesome [MFM]

[TLDR] the sex starts at 5th paragraph :P

So I get an email from this guy I know: “Tomorrow I have a sex-date with this woman I’ve known for some time, she wants an extra guy joining. She doesn’t want some random guy, but someone cool with whom you can have a chat, so I was thinking of you”. I felt honored that he was thinking of me, and I’ve never really had a request like that, so I couldn’t refuse.

Next day we meet at this music festival in some town. Bands in the bars and cafes all over the city-centre. My friend told me some stuff about her beforehand on the phone. She’s a big music fan, so she’ll be immersed in the concerts. Its weekend, so don’t talk about her work’n stuff. Be carefull with her, she can switch moods quickly. He told me just to do as he’d say and follow his lead. She’s very horny in nature, so we’d be fine. Based on this I get a bit nervous, because you never know…
