Start with eating her out

"Take off your robe," you say.

She stands and takes it off without hesitation. She is wearing nothing underneath but a pink G-string. Her breasts were not suspended by a bra, but are so clearly fake that they defy gravity.

"Panties too," you say, still sitting.

She takes a breath so heavy that her breasts heave. Then she turns around and lowers the G-string so that you can see if sliding out of her huge round ass. As she is bending over, removing the string out from under her feet, you spank that giant ass. She yelps in a way that conveys a small amount of pain, but far more pleasure. When she turns back around you see her pussy, pink lips extending out from a crotch so smooth that it's like someone put an actual human vagina onto a life-sized barbie doll.

You still have not gotten up. You can't help but feel a rush at the power of it, being able to sit there as she follows your commands. "Go lie down on the bed. On your back."

She practically runs into the bedroom and spins around to fall on her back onto the bed. You slowly stand up, and lackadaisically unbutton your shirt as you enter the room after her. Her entire body is heaving with anticipation. This is better than quid pro quo. Better than anything you could have hoped for. She wants this, perhaps even more than you do.

Once your shirt is fully unbuttoned, you approach the bed and walk around it. You kiss her greedily. Alternating between pulling her lips into yours and prodding your tongue into her willing mouth. She moans into you. As you continue to kiss her, your hand runs down her body and grabs one of her giant tits, giving it a firm squeeze, and then pinching her nipple. Her muffled moan rises in pitch to a squeak. Your hand keeps going down, down...and then soon you feel it. The hairless pink lips. Fluid is practically flowing out of them, like a steadily trickling faucet.

You pull away from kissing her. "You like this don't you?" you say. "Being told what to do?"

She nods, biting her full lip. "It's all I wanted. It drives me crazy."

The valley-girl speak is gone, as if she's struggling with it in the throes of sheer ecstasy. That's fine. So long as she's this willing.

You step over to the gap in between her legs. Those beautiful wet lips slowly parting. You get down on your knees and breath into them, and then gently kiss her outer labia.

Just that causes her back to arch. She lets out a throaty gasp.

It encourages you too much. You want there to be buildup, but you are too **** feel your tongue on her pussy. You go all in and give a long slow-lick, she moans out in a voice that breaks, becoming insensible in her delirious pleasure.

Then you grab her legs, part them, and dive in. She tastes wonderful. Wet, salty, with just a little bit of sweetness. Your tongue thrusts into her a few times, then you push it up higher and circle it around her clitoris. She screams. You wonder, based on what she's said: has anyone ever done this, to her? You very well might be her first.

You alternate between long slow licks and furious tonguing, depending on how she is feeling. You feel like she may cum multiple times, so you draw it out to have your fun. Soon, you introduce your finger, either rubbing her G-spot while you lick her clit, or gently fondling her clit while you lick the sides of her pussy. Wet squelching sounds can be heard as you practically pull her pussy toward you in a 'come-hither' motion while circling your tongue around her clit.

"Oh god Ryan...oh god," she gasps out. "I'm...like I'm..."

You pull away from her. In a moment of improvisation you ask outright. "What are you?"

"I'm your fucking bimbo slut!" she shouts out, as if the words were already inside her, they just needed prompting to come out. "I am your braindead fucktoy! Use me, use my stupid pussy and play with it or do whatever you want with it. Please."

That's all the encouragement you need. Your fingering and tonguing become even more furious. She starts to scream. Her fingers grip the sheets so hard that they untuck them as her back arches again. Finally, you feel it. Her pussy pulses, squeezing around your finger several times as her body tremors. After so much screaming, she suddenly goes silent. Frozen as her back arches.

And then her breath releases, in a gasp. She shudders once.

You stand up and lick your fingers clean. "So, you like how our deal's going?"

You find that her eyes are rolled up in her head. She is slack-jawed. For a second, you think that she has passed out.

Then she lets out a small grunt. Without saying anything, she rolls over and goes up to her hands and knees. Her backside goes back, back...until it is pressed up against you. Her head turns and looks behind you, her mouth gaped open. She lets out a whine. A grunt. But nothing resembling human words. Something is...activated, in her. Her eyes are still unfocused, delirious. She is not communicating in words.
