Incest just happen!

[neerathemall]

Those words were more than I could take. I felt my cock begin that last thrust as the cum boiled from my balls and exploded deep in her ass. She also let out a scream as her orgasm tore through her body. I think we both may have passed out. I woke up in a daze and felt my cock finally getting soft. It slipped out of her ass with a plop.

We both just lay on the floor for several more minutes before I started pushing my back against the material. I felt it give again and heard the material rip. My back was out of the costume. I climbed out slowly, my boxers were covered with cum and pussy juice. As I looked down I could see my cock was still semi hard and poking through the fly in my boxers.

I was covered in sweat and my hair was dripping wet. I rolled on my back and started trying to catch my breath as my sister worked her way out of the ripped opening. As I watched her climb out of the costume, I could see she was a bigger mess than me. Her hair was matted together and all in her face. She had lost her bikini bottoms and I could not help but admire her waxed, smooth pussy.
