OKAX-131 - I monopolized my sleeping sister's body for 8 hours

Even if she's family, she's a woman. Late at night, I snuck into my sister's room. When I saw her smooth thighs exposed through her hiked-up skirt, the last thread of my sanity snapped. As I reached out to touch her skin while she tossed and turned, my suppressed desires exploded. The guilt of incest was long gone. Holding back her moans so the family wouldn't hear, I ravaged my sister all night long as she writhed in pleasure.
