The best kind of sex. Not rape like previously thought of.

It can be long, but is usually a "quickie," sex done quickly and shameless with your partner!

Surprise sex has been going on for millenia and was quite popular in classical Greece and ancient Rome.
Guy: Hey girl, it's me...guess what?

Girl: What?

Guy: Surprise!!! It's time for some surprise make-up sex! You'll love it! It's my surprise sex for you tonight, baby!
