You test her

With a sudden snap you make up your mind.

"I want you to go downstairs to the kitchen and bring back some butter," you tell her. She looks up at you with a confused expression.

"Butter? I don't understand," she says.

"Just do what you're told," you order curtly and are gratified to see he scamper naked out of your room without further question. While she's gone you take the mirror off the wall and lean it against the headboard of your bed, then sit waiting for her to come back.

"I found it," she says cheerfully. "It was in the fridge, I hope that's ok."

"Just put it on the nightstand and come and lay down," you tell her, embracing her slim teen body as she obeys. She shivers as you stroke your hands down her skin, then notices the mirror for the first time. She looks a question at you, and you smile and push her down on the bed, loving the feel of controlling her lithe compliant body. She wriggles delectably as you stroke her, rolling her onto her belly and squeezing her sweet rump.

She purrs happily as you fondle her, then gives a happy gasp as you straddle her thighs, pressing your stiff cock against her sodden cunt.

"Mmmmm yesssss," she moans, raising her hips. "I love being fucked by you Mr. Carter, I just love it."

"Look at your face in the mirror as I take you," you growl, teasing her wet folds for a moment then slowly impaling her. She gives a long sweet groan as you fill her, her eyes half open and staring at her lust hazed face.

"God that looks so hot," she purrs. "I look like such a little slut when you fuck me!" You thrust into her with slow steady strokes, then reach over and grab the butter. Breaking a chunk off the ice cold block with your fingers you press it between her cheeks and against her puckered rosebud.

"Ohhhhhhh!" she squeaks, wriggling to escape. "That's so cold! What are you doing Mr. Carter?"

"I'm doing whatever I want," you rasp, pressing the cold butter into her ass as she squirms and squeals.

"It's so cold! And you shouldn't...you mustn't..." she protests. You stop pressing the butter into her ass and you stop fucking her, pulling back until only the tip of your cock rests between her labia.

"Of course we can stop Grace. We don't have to do anything at all. You can put your clothes on and go."

"What? No...I didn't...No! Please... don't make me leave Mr. Carter. Please don't make me leave! I'm being a silly girl...please." Her voice is plaintive with **** need and she wriggles her ass, glancing over her shoulder with wide eyes.
