Got a blowjob in a college studio [MF]

[18] I met this girl [19] through our English classes, however it was only when we were together in our college’s music studio that we got to know each other properly. She was a 5ft 3 ginger, beautiful face with an hourglass figure. I heard her sing whilst looking round the music building, and immediately asked her if she wanted to work on music together ( I’ve been producing music for 5ish years then). We then organised times around our lessons where we could meet in the studio to start working. The studio wasn’t exactly a conventional one. The main tinted window overlooked the huge music hall, and also had a side window looking into the corridor. There was a desk along both windows, where I would place my laptop.
