Sally's angry

Mr. Carter's thrusting slowed as he drained his cock into the slender young redhead. Grace writhed and bucked, wringing every last drop of seed and every iota of pleasure out of his thick cock, her gasps gradually slowing as her orgasms finally diminish.

When he pulled out of her she gave a sated groan, curling up on the bed and rocking herself, purring contentedly. Her pussy oozed cream, and she looked the very image of a well fucked girl.

"Oh My God Grace!" Sally squeaked in horror. "You got his...his stuff in you! Oh My God! What if you get pregnant!"

"Mmmmm, it's ok," Grace answered with a happy murmur. "I'm on birth control."

"Oh My God! Since when? Does Mommy know!"

"Since the beginning of summer. When Lance and I started fucking, if you must know. Don't be such a dweeb Sally." Grace's voice took on a tone of mild irritation as she glared at her sister, her fingers toying with a thin chain on her wrist, then softened again as she looked up at Mr. Carter.

"I came three times," she purred. "Three times! And so hard! I've never come more than once, and never so good. Thank you...thank you sir." A happy little smile curled the corners of her lips.

"My pleasure," he smiled, sitting on the bed and giving her a friendly pat on her sweet rump.

"Mmmmmmm, mine too," she giggled, then looked up at him with a more serious expression. "Can Sally go now sir? Please sir?"

Mr. Carter smiled down at Grace's happily satisfied face, then glanced at Sally, still looking at her sister with a combination of shock and disgust. She was still gently squeezing her own breasts, her nipples stiff and rock hard.

"You're free to go," he told Sally, picking up her shirt and dropping it in her lap. She looked down at it for a moment as if unsure what it is, then quickly pulled it over her head. She stood up and took a few steps towards the door, then looked back uncertainly.

"Aren't you coming?" she asked her sister plaintively.

"Go ahead Sally," Grace said softly, still curled on the bed and rocking gently. "I'll be along later."

"Oh My God!" Sally said in a quiet but extremely shocked voice. "You're going to do it again aren't you? You're going to let him do it to you again!"

"MmmmHmmm," Grace purred, nodding her head as she squirmed a little closer to the teacher, looking up at his face with adoring eyes. "If he wants me. He can have me whenever he wants me." She bent her slender neck towards him, rubbing her face against his hand and licking his fingers, her eyes never leaving his. He smiled down at her, as though surprised at her complete submission, but enjoying every minute of it.

Sally took another step towards the door, then turned and looked at her sister and the teacher, distraught anger in her face

"Grace, come with me! Don't...Don't do it again! Don't let him...let him do it to you! Come with me please!"

Grace's only answer was to purr and wriggle closer to her ravisher, one hand stroking up his thigh.

"Go Sally," she murmured. "You don't want to be here."

"I can't believe you!" the younger girl squeaked angrily. "I can't believe what you're letting him do! It's like you're under a spell or something! I can't stay here and watch you...watch you **** yourself!" Her voice rose to a shrill pitch as she finished her speech, then turned and jerked the door open, slamming it behind her. Grace looked at the closed door for a moment then nuzzled Mr. Carter's hand again and turns her eyes to you.

"Now where were we?" she purrs.
