Sneaky Peak

Your father married Erika's mom rather quickly and you've looked down upon them since their marriage as you think they're upstarts and since then you've always tried to make Erika's life as difficult as possible.

Despite your efforts, she has been enjoying all the teasing and this frustrates you further. She knows you're a pervert so she keeps leaving her panties in different places for you to find.

One night in August, you're smoking by the window of your room and you see Erika in the barn opposite your balcony. You see her bent over against the wall, aggressively masturbating. You can't help yourself and start rubbing one out to her. Right there. On the spot. She catches you watching her but you didn't know any better, too consumed by chasing your own pleasure.

The next morning when the house is all empty, you're in your room trying to work. Erika sneaks in and starts kissing your neck from behind. Her hand slides down your crotch and she starts nursing your cock with her panties.

Do you let her handle you the way she sees fit or do you show this upstart her place in this house?
