Roarke helped her settle into position, resting his hand upon her rump and squeezing it playfully.  His other hand slipped between their bodies, worming its way to her slick womanhood and easing between those folds to seek and press against her sensitive pearl.  Once he felt that tender nub he rubbed it lightly as his other hand drew back and popped her rear.  The swat was light, mostly sound and a shifting of her to make her body rub and press against his other hand.  Satisfied that he was properly ready to insure each blow was felt in both her rear and her sex, he began to swat her ass cheeks steadily, moving his hand back and forth to warm them evenly and make her jerk and grind against his fingers.
