Her ass

Rose changes her stance so that delectable butt of hers is facing towards you. She looks over her shoulder and gives you a big toothy grin. “So, you want to see this bum, do you?” she says, given herself a playful spank. “I guess you're like The Doctor, kind of anal." Her hands move to her black lace knickers, slipping her thumbs down the sides, ready to remove them.

"A shame you only want to watch," she says, "though if I'm going to show you mine, I'd like to see yours. Turn around."

You turn your back to her, and then you both find yourself looking over your shoulder at each other, your eyes focused firmly on her behind.

"It gets better," she tells you, while teasing you, jiggling the sides of her knickers up and down, giving a tantalising glimpse of the flesh beneath, "so much better. I bet even now I've got that cock of yours so so hard, saluting these perfect buttocks." She's right. "I bet right now you're fantasizing about me sitting on your face, aren't you, you naughty thing. Speaking of butts, you know what would really turn me on, get me so wet that these lacy things would just slide off?"

You wait for her to continue, transfixed on that ass of hers.

"Why don't you spank that bottom of yours hard, real hard, the way you'd like to spank me, because, believe me, I so deserve to be over your knee right now; I've been such a bad, bad, bad wolf."
