Colin-little brother

your little brother has always been two faced. around your parents, he acts like a good angel child, who gets what he wants. Your his older (pick gender), but he's taller and stronger than you, making him feel powerful. But when hes only around you, things are VERY different. He acts possesive, weird, dominant, acting as if you're his to do whatever he wants to do with you. Sometimes, he gets a little too close... You're in your room, trying on some dresses, to see which ones are too small on you and that you should throw out. He walks in, seeing you with an evil grin "Hey..(brother/sister)" he says as he steps in your room, closing the door quietly behind him. (you're parents are away on a vacation btw). His tall figure looms over you as you turn to face him. "You look so good in that small dress..lean over your desk, for me sweet (b/s).." he asks, meaning it to be a demand. if you deny, he will force you to instead..
