Just gotta say Blastaar, you're usually so on point but I think you're way off the mark on this one. She makes it clear from the start that even fondling her boobs is something she'd hate and get angry at her for, so there's zero implied consent there.
Getting to feel your partner's breast while cuddling is one thing, but come on now. outright fondling them for an extended time while thinking about how much your partner would hate it is quite another, even before we get to the crotch grab. Don't see how you can really justify it.
I take your point, but the story-specific situation was not the argument most people were making, but rather a general principle about boob-fondling between lovers living and sleeping together.
As to the “hating it,” the basic principle of this particular relationship is that these two get along by fighting like tigers—if one wants something, the other is going to make it hard to get it. I’ve known—although never completely understood—more than a few couples who worked by this thwart-struggle-concede dynamic that we see here. (Therapists call it putting the other person in the “one-down” position.)
But a fair cop—I can get impatient with categorical pronouncements about what is or isn’t OK, and will try to avoid engaging unnecessarily.
