with a tease filled finale

As John is considering what to do next he hears a noise downstairs. "Who else is here? You said your parents were away."

"My sister is here, we were going to have a movie night."

"Ok, I can work with that, let's finish up here first." With a thought John decided what Sarah was going to do next. First Sarah was going to feel like a huge orgasm was building up. As he thought this, she flushed from her face, down her chest and arms and started masturbating more frantically. Then suddenly she stopped and put her hands to her sides staring at John with lust, thrusting her hips into the air. She wanted to beg him to fuck her, she wanted to jump off the bed and rip his clothes off, she knew that he just needed to touch her and she would have the most amazing orgasm. But Sarah could not speak either.

John then bent down and kissed her on the forehead, and she came in her pants, flopping around on the bed unable to grab for him or hump anything substantial. It was both frustrating and exquisite, and it kept going. John enjoyed watching his girlfriend breathing raggedly twitching on the bed unable to make a sound as he backed toward the door. Her orgasm finally ended when he left the room and she was able to move and speak normally again.

Sarah couldn't remember how John had done that but knew that she had to get him to do it again. But first she had to clean up and get downstairs before her sister notices anything unusual. It's movie night after all...
