So for some context when I was 19 I worked in an independent coffee shop, I was the only guy that worked there in a team if about 10. The shop had a front of house with an office in the back.

One evening I was locking up with two of my colleagues (let's call them S and M, for fun). S was tall big boobs, mousy brown hair and a bit of a bratty attitude. M was shorter and more petite with red hair and an innocent persona.

Anyway we lock up and I go into the office... not realising they were getting changed. Both stood there in nothing but their underwear, well my cock got hard instantly... And they saw the bulge in my pants. S walked over half laughing at the facts I was hard, and ran her hand over it, unzipped my trousers and got my cock out... They both got to their knees and started sucking. Oh my god I couldn't believe my luck, this resulted in me having the best sexual experience of my life. We fucked for about 1 h, them taking turns with me. I came first on Ss tits and then gave it 5 mins while M cleaned her up before we started again, eventually cumming in Ms mouth. They made out gave me a little show, s walked over and started making out with me. "hopefully we get to lock up together again soon" she said and then we cleaned up and all left.

It was hot the next day when no other colleagues knew about what happened in the office the evening before... Even hotter when Ms bf came in that afternoon.

S and I continued to have hot wild sex before I moved away but we still see each other occasionally, usually her coming over for a threesome with me and my current gf.
