I watched myself move in and out of her mouth, then bent down to touch her butt, sliding my hand down to her tight, delicate anus.
Kassy moaned as I touched her, her body squirming in response.
I let go of her, stood beside her, and positioned her in front of me. I grabbed her full breasts with my left hand, and with my right, I slid down her back to her round butt, teasing her tight anus with my fingers.
Kassy squirmed and moaned, "No, don't do that, ah!"
Ignoring her protests, I picked her up and carried her to the bed. I placed her face down with her head on the mattress, lifted her slender waist and positioned her to kneel on the edge of the bed with her butt raised high.
I grasped her smooth, supple butt with both hands, gently parting the soft flesh to reveal a narrow crease. In the center lay a dusky-brown anus, surrounded by delicate folds. The color deepened to a reddish-brown at the center, gradually lightening to a faint blush at the edges.
