As soon as they were alone, Abigail's stepsister started to undress, revealing her perfect body to her brother. She was wearing a tiny thong that barely covered her pussy, and her small breasts jiggled as she moved. "I've been wanting this for so long," she said seductively. "You're so fucking hot, brother. I bet you've been getting your dick wet thinking about me, haven't you?"
Her words sent a wave of desire through him. He couldn't believe she was actually doing this. "You're not supposed to talk about things like that," he managed to say.
"Fuck rules," she replied, crawling towards him on the floor. She straddled his lap, her pussy pressing against his hard cock. "I want you to fuck me like you do with your booty calls."
With his words, she expressed her desire for a deeper intimacy in their relationship, echoing the intensity of the passion he shared with others outside of their bond.
