It's Monica!

Joey realises that Monica has been sleeping on the floor next to the bed all this time, and that Rachel's screaming has woke her up.

"Rachel, some of us are trying to sleep here. Can you please be quiet." Monica says without opening her eyes.

"It's not that easy to keep quiet when you are getting butt fucked!" Rachel shouts at her.

Monica sits up, and looks at Joey and Rachel. Joey looks back at Monica, smiles, and says:

"How you doing."

"Joey!" Monica explains.

"Aaoohh!" Rachel screams again. Joey hasn't stopped pumping her ass, even though he is smiling at Monica.

Monica stands up, looks at Rachel's butt, realising that Rachel is actually getting butt fucked right in front of her.

"Rachel, I know you are a slut, but why do you have to take it in the ass when I'm in the same room?" Monica says, and looks accusingly at Rachel.

"I'm sorry Monica, this wasn't my idea you know, I woke up and Joey was up my butt." Rachel says quietly. She can't believe that she is being humiliated in this way, bad enough to get butt fucked, but in front of one of her friends also.

"Aaoohh!" Rachel cries out again.

"Joey, stop butt fucking Rachel now!" Monica exclaims.

"Monica, this was your idea." Joey says.

"It was not!" Monica replies.

"Are you okay sweetie?" Monica leans forward and asks Rachel.

"Aaoohh!" Rachel replies.

Suddenly Monica notices something.
