A spanking

She seems shocked at the suggestion, but it's like a switch had been flipped in your once bossy ex. She meekly bends over on your knee and presents her sexy beskirted ass to you. For so long you've been unable to touch her, even though she has flaunted her body in front of you. Now, she's surrendered to your control. As a test, you pull of her skirt, revealing her black thong on her perfectl-tanned cheeks. She doesn't even say a word. You pull your hand back and quickly slap her round bottom. She yelps in pain. Her ass is soft and warm like a nice pillow. You slap her again, three times. Her cheek begins to get a slight red glow. On the fourth pass, your finger accidentally strokes her pussy and to your surprise it's very wet. That bitch is getting off on this!
