Ask her how she likes it.

Taking Bianca

"Bianca, how do you like your lovers to fuck you?" you ask.
"Doggie, st-style," she moans.
"OK, get in position!"

Bianca gets on her hands and knees, and you kneel behind her. You insert your cock into her dripping cunt and grab her hips. You start pulling her into you as you thrust, then push her as you pull back and repeat. Bianca starts to moan louder.

"Bitches don't moan, do they?" you ask. Bianca starts barking in a low voice. As the thrusting intensifies, she barks louder and louder. You slap her ass several times as hard as you can, then blow your wad into her. After you finish up, you smack her ass with all your strength. Bianca yelps then turns to look at the necklace again.

"Doggies lick up their messes. Get to it." Bianca crawls around and starts to lick your sticky cock as she tries to keep staring at the necklace.

You wonder if you should further humiliate her by having her crawl to a toilet to slake her thirst or just leave her naked and wet while you go look for Diane.
