Grab n' Snatch Step-Sis

My attractive teenage step-sibling Keira Croft can't seem to stay dressed when she's at home. She's been parading around in her undergarments, teasing me with her perky rear end. I finally reached my limit and took action while she was occupied with the laundry.
I exposed her chest, pleasuring her from behind with my fingers. Her enthusiastic response, evidenced by her soaking wet arousal, prompted me to take things further by vigorously penetrating her. It was clear she reveled in the experience as she eagerly consumed every bit of my ejaculation.
