Grab n' Snatch Step-Sis

My enticing young stepsister, Keira Croft, has been wandering through the house wearing only her underwear for several days now, shaking her perky hips that make my erection throb intensely. I've finally reached my breaking point, so as she's handling the chores, I approach her, yank her shirt down, and stimulate her intimately from behind. It's obvious she's into it because her vagina is incredibly soaked, leading me to position her and thrust deeply inside her with force.

She must have been thrilled by my thick shaft since she greedily took in every bit of my hot release.
