You need to bring your own ideas like DP and Eiffel Tower. Maybe if you gave them a good wanking show, they’d let you in on the main action. Think of it as an audition.

Just ignore the people behind the two way mirror. And don’t argue with the referee or his gorilla.

Where is the me too movement when you need it

So basically jacking off to a real life porno happening right in front of you?

Yeah if you joined a couple for a threesome and none of you laid down any ground rules beforehand, this would have gone wrong either way, trust me. Spontaneity is all good and well but you should agree on the basics (which forms of sex are ok and which aren't, how will you handle this before and afterwards,...) before losing the clothes.

A man having sex, a woman having sex, and a man wanking. Definitely sounds like 3 ways to me.

Well, that sucks - or maybe it did not.

I suspect one or both of the couple chickened out about really having a 3-way by the time 3rd wheel, second dick got there.

I suppose from your point of view that may be better than if he planned a bit of action with you whilst his girlfriend watched,

You deserve it for wanting your best friends gf. You sir is an ass.
