Continue to dominate her.

The shower has re-energized you both. Seeing as Isabella is your **** for the rest of the day, you decide to get your favorite sex toy the moment you got to your room.

"I'm not done playing with you yet." You tell Isabella, who smirks back in anticipation. "I want you to play with yourself while I get something."

"Yes mistress." Isabella replied, and she laid back on the bed and started playing with her pussy. The sounds of her softly moaning turns you on even more. You quickly find the 10-inch black strap-on you brought with. Pulling on the strap, you go back into the bedroom. Isabella looks up and her eyes widen as she sees the strap-on, licking her lips in anticipation. "Is that big cock for me, mistress?"

"Yes, it is." You reply as you climb onto the bed. "I want you to suck my cock." Isabella giggles, crawling over and immediately beginning to suck it. You smirk as you watch her do it as if she had been sucking cock her whole life.

"You little slut. You're so good at sucking cock!" You say with a smirk. Isabella stares back up at you as she keeps sucking while jerking it off at the same time. After letting her suck it for a little bit longer, you lay her on her back, crawl towards her, and ease the cock into her pussy. She gasps softly but you silence the gasp with a passionate kiss as you fuck her at a firm but steady pace.

As Isabella's moans grow louder, you wrap a hand around her throat and begin saying nasty words in her ear. "Cum for me, you nasty whore! Tell me whose pussy this is as you squirt all over my cock!"

"It's your pussy! It's your pussy!" Isabella cries as another orgasm overtakes her. You giggle and continue to fuck her through the orgasm, but gradually slow down and finally pull the fake cock out of her. You crawl beside her and kiss her again, just kissing her for quite a while.
