Slap her ass hard
From Create Your Own Story
As soon as she takes a bite of the pizza, you walk up behind her and slap her ass. Not expecting that she lets out a little 'ow' and drops her slice.
She turns her head to look at you over her shoulder "What was that for, naughty?" She is still grinning, so she isn't upset and you find that sexy.
"Couldn't see such a perfect ass like yours without wanting to touch it."
"You like my ass, huh?"
"I like everything about your body."
"You do, huh? And you're not tired, then?"
"Wide awake. You?"
"I can't sleep. I just gave my first blowjob, earlier, and I can't stop thinking about it." She winks.
"Hmmm you gave a very nice one. I can't stop thinking about it, either."
Then you slap her ass again, leaving your hand to rub her smooth, fine rump.
