Kurt and Blaine were at kurt's apartment in new york playing pool.
kurt: you look really hot when your playing pool.
Blaine: Eat me
kurt then runs to Blaine and they start making out, and end up lying on the pool table having sex.
Adam from "adams apples" walks in saying
kurt do you want to... what the hell is going on here.
Adam found Kurt and Blaine lying on the pool table together naked.
