Slutty step-Sister's BFF - my step-sister's BFF will be spending a couple of weeks at our place, because she has a new job, and her place is very far from the new workplace. It's all good, we've all grew up together, we've known each other since we were preschoolers. One afternoon I come from work and I find her laid on the sofa, browsing something on her phone. She's happy to see me. We exchange a few pleasantries, she knows I have a new girlfriend and she's curious how that's working out for me. I tell her it's going great so far. I love how's she's playing with her hair, how she looks at me, the tension is rising. She confesses that she always had a crush on me, and I reciprocate. She invites me to explore her body as she's getting naked, to pull out my cock and to fuck her before anyone else comes home.
