Stepbro

You got invited to do a gameshow with your stepbrother. You don't know what the show was about. When you arrived there was a room that you passed with all cutouts or circles into a wall. You were put into a room with other girls. You were separated from your brother. A man comes in and orders us all to remove our clothing and then move onto the room I just saw and leaves. We cannot argue back, so we just remove all of our clothing and go to the room. The man is standing there eyeing us all. After a good 5 minutes of staring at us all with a smirk he says we need to put our butt through the holes in the wall. We protest...confused at what is happening. He says we have to and that we signed a contract, so we have no other choice. So we do what he says. After a while we hear murmur of men coming in as we stand with out butts in the holes, only our butts visible. The man from a few minutes ago appears to now be speaking to a camera. He tells the camera that the men have signed themselves and their sister or stepsister for this program. The program will go as followed: each man choses a hole where a butt is peaking through, he penetrates the butt and decides if it's his sister or not. It goes on until every man has penetrated every butt. The only rules are: no speaking to the women, no coming back to a butt. The men are allowed to cum into the butts and can penetrate as long as they want, no condom is needed. After every man has penetrated every butt, they go on and decided which they think is their sister. The men that get it right go over to the next round, where they can penetrate the clit, and so on. Is this of everyone clear? The men all says yes, but as us women hear it we try to get out, but re completely stuck in the walls. We cannot go any way and have to face what will happen.
