Son demi-frère ne prend pas bien le rejet

Does stepsis really think that she can tease me for weeks on end and then reject me when I make the first move?Something must be up with her... Why else would she flash me around the house and brush up against my private area as she walks by? After about a week of her acting like this... something had to give! I had to confront her and find out what's going on! I walk into the bathroom while stepsis was doing her makeup... We need to talk.
