Sam and Rachel were like any other brother and sister always having moments when they could not stand each other. This weekend they were slightly upset to say the least that their parents would be going away and leaving them home. Both had plans to go out and have a good time, but their parents forbade them to leave the house.
"No, you cannot go out, how in the world are we to know that you are safe?" Their father scoffed at the mere mention of the idea.
In unison they replied, "But Dad, we are in college now!"
"No but, nothing! You are staying home. It would do you good to learn how to get along better. One day your mother and I won't be around and it will be only the two of you to look after one another. Now think about that while we are gone." With that their parents left, giggling like two school kids.
"This isn't fucking fair Rachel, I wanted to go out tonight." Sam glared at his sister, then a sweet smile played at the corners of his mouth. He starred at her for moment never realizing just how sexy his sister was. Standing there in a pair of shorts from last summer accentuating her firm rounded buttocks peeking out the rim of her shorts. Her cut off T-shirt showing cleavage he had not noticed before, the swell of her bosom visible, hardened nips showing through the white worn material. Her flushing face made her glow, she always did look good angry.
With a chuckle he started to walk away, "What you grinning at smart ass? I got to stay home too." She stomped her foot making her bosoms jiggle causing more friction against her nipples. Sam felt his groin start to twitch, as her luscious body in the fit of anger; he could only imagine what a wild sex kitten she would be.
Sam had been watching his sister masturbate for over a year now, standing quietly while she furiously fingered her clit. All the while stroking his pulsating rod, when she reached her orgasm arching her back, thighs clenching her hand he would shoot his wad all over the floor. There was something magical in the way she pleased herself, he wanted so desperately to walk in, slide between her legs and lick her clean.
Fighting these urges for weeks now he pondered if maybe, just maybe this weekend he would give her the treat of her life. And maybe he would see just how far she would let him go. He knew his massive meat would stretch her tight little cunt giving him added pleasure.
