It's been a largue trip with your father Adam; around six hours, to get to know what would be part of a newcome family. He's talked you about Margaret and Chachi with confidence, asserting, at least from his concept, that they're people to trust and not to be scared about.

You get to know them in dinner. Margaret is kinda serious; a proud smoker it seems. There doesn't seems to be a very strong bond between her and her daughter, Chachi, who seems to be shy; the kind that doesn't speaks or does more than needed. Although their relationship appears to be farthermost, nothing hints for a conflict; from time to come.

After you end your dinner and help Chachi washing half of the dishes, you're told that you have to sleep in your new step-sister's room; her bed is a little bigger than yours and it's better than driving six hours back home after all. There's no objection; they are slightly drunk, talking trivia, under the effects of wine and they don't care of leaving you alone with such docile creature.

It's a comfy space you find yourself inside. Her bedroom is not as girly as you would expect. It has everything you need, with no more personality involved. The lamp and its dim light induces just a little of somnolence. She exits the closet, in her pajama shirt and shorts and she sits on the edge, taking a breath as if frustration was washing her inside.

"H-have a good night." She says, trying to be kind; completely indifferent of your unwanted invasion.

You're lying in fetal position, looking just at the smooth colour of the wall. The lights are turned off and she lies beside you without much reluctance. You sense a few jerks but you try not to look at her. Not complaining; not moving, more sounds start filling the sharp space separating both of you. You can identify flesh and faint, supressed moans at your side; there's an alluring smell of sex. She might be masturbating at the assumption that you're asleep. She may like a hand, but you should know pretty well fucking your step-sister just now might be problematic. What will you do?
