Mercer felt his heart pounding in his ears as he squeezed her bare ass in his hand, and shook off any regrets, any doubts at that moment, and ripped away the thong, the only remaining barrier from keeping her anus hidden from sight, and he felt his erection strain even more against his zipper, which would incidentally press against her stomach. Her squirming against his erection only made it much more worse, and he gritted his teeth at her pleadings. "Daddy knows you've been sneaking outside, and this is the third time this week. I have to punish you," he said, and raised his hand, and brought it down lightly, smacking her on her right ass. He watched with an obsession at her ass as it jiggled, and the feel of her cheeks against his palm felt magnificent.<br/><br/>He raised his hand again, and this time, brought it down hard enough that it left slightly red, causing goosebumps to rise all around her ass, and the jiggling lasted longer. Licking his lips, he raised his hand, and brought it down, again and again, the sound of flesh being spanked echoed in the room, and he reached with his other hand to pull Samia by the hair, causing her neck to rise up in an awkward position, and Mercer leaned down and kissed her passionately before biting down her lip and letting her head fall back down. "I'm doing this for your own good, Samia. This will teach you a LESSON," he punctuated the last word loudly as he abruptly and suddenly shoved his middle finger up her tight, unclaimed asshole, burrowing through the hole until he could push it up no more.
