Your filling Sierra's ass.

You can see that she is playing with her tits with one hand and rubbing her pussy with the other and you know she is going to cum again soon. "You are such a nasty black slut," you sneer. "A dirty nasty slut."

With a sudden loud cry, she flings her hair back, her back arching as she climaxes, her ass clenching tightly around your cock. "Oh yes, oh yes, oh John yes," she cries, her thighs squeezing against your sides as she keeps pumping your cock.

It is more than you can bear and your own orgasm tears through you, as your cum shoots out of your cock, filling Sierra's ass. "I'm cumming, Sierra, I'm cumming!" you cry, shooting your load into her.

Her cries become incoherent as she comes again, your climax triggering her own. Her ass squeezes every last drop of cum from your pulsing dick before she collapses forward over your legs.

You pull your cock from her ass. You watch with satisfaction as globs of your cum slide from her gaping hole down into her pussy. "That was fantastic, Sierra," you sigh.

"Mmmmm, yes it was, John," she agrees. Sitting up, she moves over and falls beside you, her chest still heaving, her pulse still racing.

Reaching over, you play with her nipples. "You really are a nasty girl," you tease.

"No, I'm not," she pouts. She smiles. "I'm your dirty nasty black fuck slut," she laughs.

Curling your hand around the back of her neck, you pull her to you for a long deep kiss.

When she finally releases your lips, she whispers, "Well, I’m your dirty nasty black fuck slut when I don’t make movies. My ass is yours when I’m home alone, John!"

Images of how you can take her flood your mind, all the different positions you can fuck her. "I don't get a piece of your pussy again?" you pout. “I've also dreamed about having my cock in the gorgeous cleavage of your big tits.”

"Well, maybe you can use them also," she agrees.
