When I was in high school in grade 10, my friend and I had sex with this girl in the library. She was my best friend's gilrfriend and I got invited somehow as we always walked home together.

It started with some heavy peting at the reading tables in the library after school - and then progressed to the small "music/reading" rooms in the library. We noticed that one of the rooms had a lock - we shut the lights and could only see the glow from underneath the door - enough to cut some inhibitions.

I had never touched a girl before - she sucked my friend while I was just sitting there on the couch in the dark - she then took my hand and let me play with her pussy and tits. She eventually got out of her clothe and was completely naked and she then got on all fours kneeling in front of me on the couch and undid my pants and pulled them off - she then began giving me a blowjob on the couch while my friend started fucking her from behind - it was all crazy.

I then heard my friend cum and he was done quickly and sat on the couch next to me. I am quite endowed and she push me up, lied on the couch with her pelvis up and she wanted me to fuck her - so I did while my friend sat right next to us - he was playing with her nipples and kissing her - I was on fire and somehow was able to penetrate her for a good 10 minutes with my big cock and she was super tight - I finally pullled out and came on her tits.

I saw her a few years ago and she was married with three kids - I told her that I felt bad for what happened in school and she told me that we were just young and figuring things out. I know that she came from a broken family and I felt bad for years.
