When I was at school (I was 18, and so was she) I had a job as a school cleaner. We’d do two hours after each day and it was really high pay for a teenager. My girlfriend at the time also did the same job…

Most of the work was unsupervised and my friends and I would goof around a lot, explore different parts of the school, etc. Once she thought to surprise me in my designated cleaning rooms, and she had that look in her eye! She came up to me, undid my trousers (without even a kiss of a word) and started sucking on me.

It didn’t take me long! I had an intense orgasm straight down her throat, so hard that my leg was like twitching the whole time.

We did a lot of fun and risky stuff. This was one of my favourite memories!
