Carry on watching

I restrain myself from entering the room and watch as Casey tastes Kyle's cock. I imagine myself in Kyle's place as the Casey takes the full length of his cock into her mouth. My eyes close as I drift away into my imagination, with Casey sucking my cock like the dirty little slut she is. As I open my eyes I realise she is staring straight at me, and our eyes meet, both of us frozen in shock.

"Don't stop now baby" Kyle tells her, still oblivious to my presence.

"Just having a breather" Casey replies, her eyes still locked on my figure at the door. Suddenly a grin spreads across her face, and she winks at me before flicking her hair back and wrapping her lips back around Kyle's cock. She doesn't seem at all bothered by my presence, and in fact renews her oral **** on Kyle's cock with increased appetite, as if eager to please her audience.

Just as I'm getting close to coming watching this little slut, I hear the front door open and hurry to put my cock away.
