Situations where a girlfriend accidentally or intentionally shows some nudity and her boyfriend is upset or embarrassed is really great!! (especially if his friends are there).
A boyfriend's feelings when she's topless among other people can be many and varied, but it's always a very exciting and fun situation.
In this photo, the boyfriend is clearly annoyed and embarrassed that she has her breasts exposed while the other girl remains covered.
This is partially similar to the amazing thread "Exposing girlfriend topless or even naked in front of friends"
