I really liked how Petal is pushing the MC into reenacting. I now hope she has seen even more sexual interaction--and we learn of this in the coming week. Her pushing him seems very reasonable, based upon his built in reluctance. She has to make him see through it and let him know she wants what only he can give her.
You are the best at giving us a peek at their thoughts, and seeing that these two are anxious but inching closer to being truly and deeply in love. And heck, rules are made to be broken, or amended, right?
