GVG-660 - Alone in a cramped room... I couldn't resist my sister's defenseless body

I had to share a room with my sister because our new place was too small. Watching her sleep and change in front of me every night was pure torture. I finally snapped and took what I wanted. Now, we're trapped in a cycle of forbidden pleasure, where she fights the guilt but craves the touch, and I can't get enough of her body.
