Looking for a story and am getting desperate

I’m looking for a story that I read some time ago. It involves a nerdy guy being the only guy in a study group during high school. During the holidays while in college he meets up with his 4/5 (obviously) super hot female study buddies. They plan to go clubbing and invite him along, but have to crossdress him because bouncers don’t check the IDs of women.

He then gets hit on in the club and rescued by some of his study buddies who take him back home and peg him.

I hope one of you knows this story because I’ve run out of ideas to find it.
