She feels herself getting wet.

Unable to resist her bother's will, Courney looks into the mirror. As she does, James begins to slide his cock between the crack of her legs as it began to harden again. As she looked in the mirror, Courney's eyes slid from her face to her brother's movements. As she watched, James began to feel lust creeping into her mind and couldn't help but smirk.

After moving so his cock was between her legs to brush her pussy, James leaned over to whisper in her ear, making eye contact in the mirror.

"You like this, don't you Cout. You like that your brother is using your body as he pleases. It makes you hot doesn't it, you little slut."

James felt a sharp increase in his sister's lust, and his cock began to become slick with her juices as her pushed in and out between her thighs. Despite this, she still tried to rebel by scowling fiercly at her brother in the mirror.

James simply laughs and begins to think about what to do to her next. He could easily take her pussy right now. Or he could continue playing with her and see if he could get her to beg for his cock. He could also decide to fuck with her mind by making her horny for only him before leaving her alone.
