Watching two women...or surprise threesome

[manloveswomen]

Any stories about a man watching two women having sex?

Then perhaps a third woman comes in & he has sex with her.
-------------------------------- or-------------------------
Man & woman are in beginning of foreplay. Woman tells guy she has a surprise for him. Her friend or sister (his or hers) or 18+ daughter, etc. (whatever your pleasure) walks in & joins them. They did not discuss this beforehand but the woman knows her guy would not object. I like the element of surprise.

My god that is so hot!
You're right about surprize, and I think that's lacking in most (if not all) of the stories here.
The encounter is always either pre-arangend or accidental, but not purposly yet unexpected.
