Relieving 4 years of sexual tension (M/F) (long)

Lot’s of relevant back story. You can skip to the bold section if you want.

Four years ago, I started college and moved into an on campus apartment. My apartment soon became the one where everyone hung out and we were all drinking one night when Thomas walked in. I was drawn to him the first time I saw him. He's 6'4 with light brown hair, blue eyes, and a gorgeous smile. Completely my type. At the time, I was kinda chubby with bleach blonde hair and an inappropriate amount of cleavage. We officially met and started chatting and drinking. We were having a nice conversation and decided to ditch the party to go to his apartment upstairs, where we proceeded to talk all night long. We just clicked.
