I hadn't seen my sister in a long time, and she was sleeping unguarded. I noticed that at some point she had developed into quite the woman. Before I knew it, despite knowing better, I touched her and started jerking off... Shit! She woke up! My dick is out too, and there's no way to explain this! But surprisingly, she offered to help and started rubbing against me with her pussy! Wait, is she wet? Fuck! It went in! I'm about to cum!
