Go for her pussy

I decided to move on to my sister's pussy. Since she was wearing a skirt, it was easy for me to place my hand on her leg and move it up towards her pussy, caressing her thigh. Her skin was so smooth and warm to the touch. I pushed Cassie's skirt up enough, so I could see her panties. They were matching her white lace bra.

With my hand between her thighs, I pushed her legs apart slightly, giving me access to her pussy and then I moved my hand to her panties. They were soft.

Slowly I began rubbing my sister's clit through her panties, the sensation was robbing me of all common sense. My sister began stirring in her sleep as I pleasured her, her breath was getting faster and a wet spot started to appear on her panties. But she did not wake up. She can be quite a good sleeper, especially when she was drunk.

My fingers found their way past Cassie's panties and got wet as they came in direct contact with her clit. I slowly pushed two of them in my sister's pussy and pulled them out again, moved them to my face and smelled them. The smell was intoxicating. I didn't know my sister could make me this crazy for her body. Immediately I let my fingers go back to what they were doing beforehand and continued caressing my sister's pussy, though now not through her panties anymore. My fingers went along Cassie's pussy lips, then dug inside her clit. I moved them in and out, again and again.

My sister now grabbed onto me, breathing faster, but was seemingly still sleeping. I lost all care of whether she could wake and continued to finger fuck her.

Then she started moaning and I heard her say "Faster". I didn't stop, I couldn't. She was awake now, I knew that. She didn't scream at me and called me a perv yet or stopped me.

So, I continued.

And, well, I made my sister cum.
