Can this be a different story-

Something doesn't add up .You might be way too touchy at the beginning?. you want to play right away?...maybe try to touch her boobs? or what worse her pussy? , who knows ? Her reaction is way too much if you just give a friendly hug?

Then you sit up again nd touch her "under her shirt" Seriously !! After she swatt you at the beginning? You're a brave guy ! It doesn't make sense at all !
