Your girlfriend has just come clean with you and told you she has slept with someone else. But it throws her off when you ask for the details, but not in an angry way, in a turned on kinda way. She can see your cock is hard through your trousers... but she'll happily tell you about her being fucked by another man while you wank your cock if that means she's not in trouble! She'll even finger her cunt while she tells you!
