Photo time.

We both got up off the bed, grabbed our phones and headed for the door. We stepped out into the corridor, keeping an eye out for our targets. I decided my best bet was to check my sisters room and hope I could sneak in a quick photo without her noticing. I opened the door and peaked in but I couldn't see her.

"Where is she" Ash asked.

"No idea" I responded "let's check down stairs".

We headed for the stairs and creeped down them making sure to make as little noise as possible. It was difficult to stay focus with a naked girl standing right next to you. She obviously felt the same, as I soon felt her wandering hands on me. By the time we reached the bottom of the staries we were feeling each other up. By the time we reached the kitchen we were wrapped in each others arms in the middle of a passionate kiss. She wrapped her legs around my waist and I **** her against the counter.

As our hips collided i heard a lustful moan. "You sound like your ready for this" I said

"I thought that was you" she said

"What?" I asked "that wasn't me"

Then we heard it again. We kept quiet and her a muffled voice coming from the basement. We had a small cinema room down there with a projector screen.

"Let's go" ash said as she pulled me down the stairs. I was not prepared for what I saw.

My eyes when to the projector screen first and to the two people fucking each other like crazy on the screen. Then I noticed the trail of clothes leading to the recliner and to my sister who was laying on it. She was compleatly naked like me and ash, except Lizz had one hand at her crotch as she buried her fingers into her pussy and was bucking her hips up to me her hands thrusts. Her moaning was much louder now and I could see that she was compleatly lost in the moment. We could have walked right up next to her and she probably wouldn't have noticed.

I thought about taking the picture but I came up with a better idea. I switched my phone camera to video mode and began filming my sister finger herself.

After a minute or so her movements became more frantic and her moans increased untill she cried out and arched her back. She gripped her seat and then collapsed back into the seat compleatly spent.

I had just watched my sister orgasm in front of me and I had caught it all on tape.
