As I walk into my room, I hear a soft moaning sound coming from under my bed. I bend down to investigate and see my stepsister, Olivia, lying there with her mouth wide open, eyes closed in pleasure. She's not doing anything, but the gentle rise and fall of her chest tells me she's breathing heavily. Her fingers are slowly stroking her swollen pussy lips, and I can see a small trickle of wetness seeping through her panties.
I grin and whisper, "Olivia..." She lets out a long, drawn-out moan at the sound of my voice. I crawl closer to her and start rubbing my hard dick against her ass cheek. She whimpers and bucks her hips against me, trying to get more contact.
Slowly, I slide my cock into her waiting mouth, feeling her warm, wet tongue glide over the head and down the shaft.
