How far will you go?

I have a good pal that such shit can fly.

The thing is, we mostly act weird like that when other people are around and will feel awkward from such behaviour.
The furthest we have even gotten is making super detailed innuendos, sit really close to eachother and "flirt".
Truth be told, I'm happy no lines are crossed and really dig the trolling we can do to the rest of our friends.
