(Her Secret Fantasy, continued by Klol...)

You come back after a few hours, and you know something is not right when you see Rachel’s face. She’s grinning like an idiot.

“What is it, slut?” you ask her, genuinely curious.

“Sorry, Master, I’ve… ”, she trails off, feigning shyness.

You grab the back of her long hair and yank it back. Not too hard, just enough to let her know who’s in charge. “Speak”, you smile, enjoying this too much.

“Master, I’ve been a bad girl. When you were gone, I… I masturbated and came.”

You stare into her eyes. She’s still grinning. “You disobeyed me?” you ask, completely serious.

“I was too horny, Master. I… I couldn’t help it. I’m sorry.”

“Oh, you’re not sorry yet, slut”, you tell her, tightening your grip on her hair, “but you will be.”

“Really, Master?”

She’s clearly enjoying this too much. You decide to make things a little more real now. You slap her across her face. “Yes, whore. Really.”

She looks back at you, and the smile is gone.

“Come. Across my knees. Now.”

Your girlfriend crawls after you to the sofa and gets across your knees, presenting her naked, massive butt for spanking.

“You’ve been such a bad girl,” you say.

Rachel silently squirms on your lap. As you caress her ass with one hand, and play with her mouth with the other, your erection grows. You feel the weight of her hot, naked body on your lap, and your erection pushing against her.

“To whom do you belong?” you ask her calmly.

“I belong to you,” she whispers.

Crack! Your hand smacks her asscheek hard, leaving a red mark. She squeals.

“I belong to you, Master”, she whispers again.

You nod soundlessly. Then you smack her fat ass again, and watch it wobble. Again — you see the ripples across her body. Again, hard — you notice how her body tenses up in anticipation of the smack, and it’s beautiful. Again — her assis a nice shade of pink now. Again. And again. And again.

By the time you’re done, her assis sore and your dick is painfully erect.

“On your knees.”

Rachel slides off your lap and gets on her knees. You both look at each for a moment. You can see she’s not smiling anymore. She’s truly a slave now — this is what she really wanted. You can see it in her eyes.

You gesture her to crawl closer. As she does, your hands grab her head and guide her to your dick. She opens her mouth and let’s your rock hard erection slide inside her soft, warm mouth. You can’t help but moan.

Soon, she’s steadily bobbing her head on your dick. Her hands start massaging your ball sack. Your hands let go of her head. Her mouth moves south and she’s coating your balls in her saliva while wanking you off.

“Am I being a good girl now, Master? Am I a good girl?” your girlfriend asks while giving you a furious handjob.
