She gave you head and you gave her what?
I can't speak for that woman but that would piss me off
! She lays there in bed with you all night, you do nothing. She sucks your cock in the morning, you cum (hopefully not in her mouth but I may be hoping in vain), you do nothing!! Damn - I'd be fucking steamed at you! She must really like you to be coming back.
Mind you - that is me putting my interpretation onto someone else's actions. She may be totally OK with that. I guess in that situation I would have made the first move - but then she did. She sucked your cock.
