Paint her thick ass

You need to see that glorious booty one more time as you finish. "Turn over and show my that ass," you growl. She pulls off of you, then flips over, spanking herself and bouncing her ass.

"Right here," she tells you.

With titanic effort, you keep yourself from blowing immediately, edging yourself while spanking Callista roughly. When you are out of danger, you plunge back into her from behind, fucking and slapping her furiously until you reach the point of no return.

Pulling out once more, you jerk yourself a few more times, then release with a roar of triumph. In rapt fascination, you watch your cum splattering, splashing, and sticking on her jiggling rear, up her long, curvy back, dripping down the back of her thighs and balls. You've never cum like this, and you can hardly believe how big your load is. Callista turns to look back curiously, and her eyes light up at the sight. "Holy shit, nice work," she congratulates you. "I've never been painted this good before." You shake out a few more drops onto her ass, then twist around until you are on your sides facing each other. She kisses you sweetly as you hold her close. You fall asleep in her arms, and your dreams are vivid and erotic.
