I'm not really sure why hugs would be given at an investor/pitching session, so maybe this is kinda moot, but I've certainly given a couple of half-hearted one armed hugs which turned into sideboob grazing and I definitely wasn't trying to feel the other person up. It's kind of like when you go to shake another person's hand and they grab your fingers instead of your palm and then it becomes a totally awkward handshake because you didn't get your hand in there far enough. Anyway, I have no idea if this was the case, but you probably don't want to pillory someone unless you're absolutely sure the guy is a complete d-nozzle.
