I guess most men dream of a young 18 year old who has a thing for older men - well, I was later than most going to Uni - and there I met Jayne. Jayne was 18 at the time and this is just one of our exploits.
Jayne was, to say the least, adventurous. She was always up for someting new or different.
We had been having sex for about six months at this point and had done it indoors, outdoors, on the beach, in a wood, you name it.
This time (I swear) we had gone to the library to study. (Yes, really). We were on different courses, and our work had taken a hit because we spent far more time in each other than in study.
So Jayne was working - I was working. After a couple of hours, Jayne stretched in her chair and said we needed a break. She came over and sat on my lap.
The library was built in a converted church on campus and had many little nooks and crannies, one of which we were in. Cuddling soon became kissing and kissing soon became petting as I slipped my hand up her skirt.
For a change, Jayne was wearing panties. She had learned the sexiness of NOT wearing them and rarely did these days, but today she had a pair of pale cotton bikinis on. I was stroking her through them and delighting in how wet they were. Jayne was at risk of dehydration when she got horny, and I have never before or since met a girl who squirted as much when she orgasmed.
Well, I guess we were pretty involved with each other, but Jayne nodded over my shoulder and I took a look to find a girl from my course watching every move. Anna was a tall, elegant girl who was pretty aloof from the rest of us, yet here she was, red face and neck watching me finger my girlfriend.
I teased around the top of Jayne's panties, almost slipping my fingers under the material but them pulling back. I looked at Anna who nodded, mouthing the word "Please". For a while, all Anna could see was my hand under the material, but then I eased Jayne's panties down and Jayne spread her legs wide while I fingered her to orgasm.
Now, Jayne was never one for being shy. After she had cum she said "Anna, leave your panties on your chair when you go." I saw Anna scurry out a few moments later.
Jayne smiled, got off me and came back with a small black pair of panties that were soaked through.
I can't say what Jayne and I did next but you can guess, I think. All the time, Jayne and I took turns in smelling Anna's panties.
Two days later, Jayne and Anna got it together and the final year of Uni was "interesting" in many ways!
