Is it okay if I feel up my best friend's girlfriend in a pool?
Why would you feel someone up like that?
I didn't feel bad or any sympathy for her. She got what she deserved!
While you may have believed that you could do something like that, it is completely wrong. Not only should you never feel up your best friend's partner because it is extremely rude, that's also highly illegal if she did not ask you to do it. You should never invade someone's privacy like that and touch any part of their body or else you could get into legal trouble.
What are you talking about? I didn't do anything ;)
Switching your story isn't going to fool anyone now. You committed an inappropriate sexual act and should apologize immediately. Be more considerate of her feelings and only touch her if she gives you express consent.
