You mean OOCly, we're supposed to feel something??
No. Okay, how to explain...
You are driving your character. If your character gets smacked in the face, you read the emote of the character smacking her in the face, and you react accordingly. If the emote says, for example, it was a hard, full on punch, you're going to play the necessary reaction. If the emote says it was a gentle and playful slap, likewise.
If your character is being screwed, you're going to read the emotes and YOU are going to decide what your character's reaction will be. So if your character is being screwed in a way that you, the player, don't think would feasibly bring her to orgasm - do you play it as if it would anyway?
In other words, are you the furring equivalent of the GE superbow who gets down, kicked full force in the face, and say "ow" - or do you try and put some realism into your RP even when your character is being screwed?
