After our parents remarry, I gain a shy adult stepsister who rarely speaks up, goes along with whatever happens, and has trouble rejecting pressure. She even goes braless at home. Taking advantage of her timid nature, I harass her day after day and constantly play with her nipples. She dislikes it but cannot firmly refuse, and the daily stimulation gradually becomes addictive. Eventually she finally voices her own desire: “Big brother, I want you to touch my nipples.”
