Didn't really know how to tackle this when we first saw it. On one hand this is every straight guy with gays friends nightmare right? This is their justification for not wanting to be friends with us in the first place. Even though they do similar things to women all the time, but thats another post. This is wrong. There are so many 100% gay and bi guys that will happily let you bust it wide open that you don't have to go around trying to trick a straight or possibly straight person into drunk shenanigans.
Now, do he look like he was enjoying the head? Maybe...but who doesn't like drunk head?
No means no. So don't waste your liquor.
