Ass red from hard spanking, time to take it rough from behind

A woman with bright red hair and butterfly tattoos lies on a bed as a man spanks her bare ass with his hand and a leather belt. Her skin reddens visibly with each strike while she reacts with mixed expressions of pain and arousal. After the spanking, he positions himself behind her and penetrates her vaginally as she remains on all fours, moaning into the mattress.
