"But I am tou....."
"Noooo!" Interrupted the Slayer. "Not there. Touch me lower!"
"Oh."
When the girl hesitated for only a fraction of a second Buffy's lust took over. She grabbed Dawn's hand and thrust it into her panties. Unsure what to do, and surprised by Buffy's lust, Dawn uncurled a single finger and lightly outlined Buffy's sex.
"God...yes. So good." Buffy panted out. "Please..."
Dawn looked confused at Buffy's plea. She increased her contact, which was not difficult since Buffy was raising her hips so far up and off the bed she looked like she was performing a gymnastics exercise.
Then, with little warning, Dawn sunk a finger deep into Buffy. Ironically, it was the contact, and not the lack thereof as Buffy threatened earlier, that made the Slayer explode. And explode she did.
Buffy awoke in a familiar position. She was sweating and it was still dark outside. Visions of her dream were still in her head and she swore that the smell in the air was more than just her distinct musty odor. She could smell Dawn. Or so she believed.
When these dreams had started several weeks earlier they had always surrounded Buffy seducing an unknown figure. While the figure had inevitably been Dawn, Buffy drew solace in the knowledge that the dreams had always ended when the "shocking" revelation had been discovered.
However, soon Buffy did not wake up as the dreams extended into the lovemaking. With the sessions growing more and more graphic every night. And the dreams did come every night without fail. Soon Buffy would seek out Dawn and create a sexual situation knowing exactly what she was getting into.
Tonight's dream was the first time Dawn had ever reciprocated. Judging by Buffy's reaction the idea appealed to her. What was not different about tonight is that Buffy was too turned on to go back to sleep. When the dreams had first started Buffy had resisted the urge to touch herself, despite the fact that the urge was so strong. She felt guilty for her thoughts.
However, the urge would grow each evening and finally she began to masturbate every time she awoke. She tried to think of anything besides Dawn but that too had ceased. Now Buffy found herself in her bed, hand between her legs unabashedly thinking of her sister being there with her.
Much like in the dream, Buffy's orgasm did not take long once her fingers came into contact with her sex. Buffy came with a powerful shudder. She lay there panting as guilt once again washed over her. As her normal breathing finally resumed Buffy decided that this was the day she would do something about these feelings.
