Last night you invited her to hang out in your room, the two of you talked until early morning. Apparently she was too tired to go back to her room because when you awaken she's in your bed. She rolls over, says good morning. She volunteers to make breakfast. But then she notices your morning wood. She jokes about it, keeps pulling your underwear down a little, until she can finally see your hard penis. She still keeps laughing about how you got hard in front of her. She's not being mean, just being fun.
