A little red head

When ever Lisa came home the first thing she would do is go to the living room and watch T.V. on the floor. The floor wasn't very comfortable but it was closer than the couch, so Lisa would often switch positions when the previous became uncomfortable. Lisa brother favorite position was when she stick her butt in the air, he would often come home from work and spend a few hours watching Lisa watch television. 
He didn't start viewing her with lust, but as his work became more stressful, he found her to be a very relaxing reliever. Her cute behind swaying every now and then, eventually his lustful eyes became lustful actions. One day he came home before Lisa and broke the t.v, making Lisa have to go to his room when he he suggested to her that she could use his T.V. . 
For a hour they both watched her favorite shows, but he couldn't wait any longer. Her favorite show was about to come on and he switched the T.V. off, whispering to her that if she wanted to watch her shows he would need her to take off her clothes. Being his sister, Lisa wasn't to hesitant, she quickly took her clothes off, not wanting to miss her favorite program. 
He turned the television back on.
She quickly became lost in her program, she was addicted to her afternoon cartoons and her brother took advantage of that. He stripped off his clothes and she wasn't aware at all. He was fully erect, just from Lisa naked body. She was already in his favorite position, he came up behind her and rubbed his rod against her cheeks. To him it was blissful, to Lisa it was annoying, but she didn't say anything due to not wanting to be kicked out.
As he continued, grabbing her small cheeks, thrusting his hips against her back. Lisa could feel the shaft of his huge rod rubbing against her small privates. Slowly she lost interest in her show and started to pay her brother more attention, her mind slowly going blank, her face glowing red, her teeth clenching from the new, unfounded pleasure. Her brother built up speed and her eyes glazed over. 
Ecstasy
is bless.
