"I've never had so much oil on me at one time before," she says with a smile. "It feels wonderful!"

I fall to one side and lay beside her, propping my head on my hand, watching her contentedly. She's still running her fingers over her belly playing with the thickening oil. She sticks her thumb into her navel and with a wet "squish" the warm spunk is forced out over the rim in all directions and flows over her flat tummy. She then extracts her thumb, but it doesn't leave her navel easily. So firmly it's seated inside her belly hole that a slight vacuum has formed and the rim of her bellybutton clings to her thumb like a pair of sucking lips pulling the surrounding flesh upwards until the seal breaks and the thumb comes free with a soft "pop!"
