I have the mother of all stories.
First year of university, before I came out of my shell, I was a shy, overweight virgin who didn't have a lot of experience with women. I started meeting people and became good friends with this super-cute Indian chick. One night she texts me up and wants me to go out across the border to Hull to party, since the drinking age in Quebec is 18, oh, and she's brining her semi-goth, but still pretty cute, roommate as well. I figure what the hell, and I was actively trying to improve my social life, so I rush, shower, and meet her there.
At the club, things immediately get crazy, we're grinding, dirty dancing... the works. And not just with her, but with the roommate as well. By the end of the night, we werre doing a three-way dance and she was just flat-out making out with the roommate. After a couple of minutes of this she declares she's tired and wants to go back to the dorms. So I grab a cab, with me in the front seat and them in the back, practically having sex, kissing and groping and MUCH more. So we arrive at the dorms and they both ask me to come upstairs for a "drink". I didn't live in the dorms and in my liquor addled brain, all I could think about was that I would get in trouble trying to sneak in the dorms at 2AM. I declined though they were literally BEGGING me to come up with them.
Eventually, they left to go up and when I got to my place, the cab driver, this grizzled old Pakistani guy, just looked at me and shook his damn head. And that's when it hit me like a ton of bricks. I immediately hopped on messenger (which was huge back in the day) and they went on cam and started doing some stuff.. but after a couple minutes they decided they were tired and went to bed. I stayed up until like 5 am alternately masturbating and crying (i wish i was kidding). We stayed good friends for a while but I never got another shot. The saddest part is i talked to an ex of hers a couple years later and he said it was basically all threesomes, all the time with them... and it could have been me.
