My university in the late 1960s was still divided into single sex colleges and there were still moderately tight rules intended to stop students of the opposite sex staying overnight etc. These rules relaxed very rapidly within a very few years of my graduating, but while I was there, we were still in something of a 1950s time warp.
It took me a while to find a friendship group among the seemingly self-assured, mainly private school boys in my college. And I had very little contact with girls in my first year. There were some very beautiful, chic girls around in the city, but they seemed completely unattainable. At some point early in my second year, I and a friend were invited to a party at one of the girls' colleges on the other side of the city, where we chatted up a couple of attractive girls 'freshers'. The 1960s were starting to influence even the diehard institutions of the university. Having never been inside a girls' college before, I recall being surprised to be allowed to visit the girls' study bedrooms. I don't recall what 'progress' was made on this occasion, but clearly enough for the girls to want to meet us again. Being an all-girls college, meeting anyone in trousers must have been a pretty major event. We were pushing at an open door. I suggested to the girl I fancied (I'll call her Fiona) that at the next weekend, I should collect her in my car and we could go back to my college. She leapt at the chance.
The following week's lectures seemed to last an eternity. I had only one thing on my mind. I suspect the same could be said of Fiona. On the appointed day, I picked her up and brought her back to my college. I have no recollection of whether we did anything else or simply went straight to my room. I suspect the latter. We began kissing and fondling each other the moment we had got into the room. It was on the ground floor and to have some privacy you had to draw the curtain, but this wasn't too glaringly obvious from outside, as the room was tucked away from the main part of the college. Things proceeded rapidly, with her allowing me to fondle her small breasts while we kissed enthusiastically. She had a beautiful mouth with naturally quite full, pouty lips which, with hindsight were probably perfectly designed for giving a blowjob, though I never experienced that with her. They were very agreeable to kiss.
