Use your finger, but not how she expects it.

"Oh, you're going to get my finger, Melody." You smile in an evil fashion. You slips it slightly into between the moist lips of her pussy. She gasps and moans in unabashed sensuality. She is already soaking wet and she coates your finger in wetness without you having to move too much.

"Put it inside me, master! Please!" She begged. You give her a slap on the ass and she squeaks out loud.

"Like I said, you'll get my finger. Just not how you might expect it." You trace your finger past her vaginal hole, trail across her taint and inbetween her ass cheeks, resting on her tight puckered hole. Melody goes rigid in surprise. "Now I believe you were saying something earlier about how this feels good?"

"Y-yes, master." Melody replies softly.

"Do you want me to finger your asshole, you naughty little girl?" You ask in a voice that was half-growl. It seemed to turn her on even more and she didn't even hesitate before nodding vigerously. "That's a good girl." You say before working your fingertip into her ass. Melody bites her lip hard and shuts her eyes tightly. You smirk to yourself as she grabs onto the discarded blue blanket and clutches it. Without a second thought, you push and plunge your finger into her, like she had done to you. Melody's eyes shoot open and she lets out a delightfully lustful scream. Her asshole tightens back up around your digit and you like the feeling. You can't help but wish she was tightening her cute little asshole around your erect cock.

"Ohhhh, God." She moans, adjusting to the feeling of a finger up her ass. You smile and give her another spanking. She yelps as your hand swats against her cherry-red ass cheeks, her asshole tightening back up. She whimpers at the stinging feeling, but quickly goes back to maoning when you move your finger in and out of her warm posterior.

"Do you like this?" You ask her. She nods in embarassment. "Tell me."

"I...I love it."

"What do you love?"

"I love your finger in my ass while you spank me, master." She replies dutifully and you can tell she means it. You smack her ass again and continue to work your finger in and out. You keep at this for several minutes and she moans and cries out appropriatly to your actions.

Finally, you speak up again. "Do you want to cum, you naughty girl?"

"Y-yes, please master!" She enthuses. "I want to soooo bad."
