I've dumped my boyfriend. Now he wants cock..

Sis takes her jeans off revealing a MASSIVE 10 inch cock. Marc sits down to take the whole thing into his throat and begins to bob his head aggressively.
Sis lays back on the bed and looks out the window meeting my eyes. He looks alittle shocked at first but then smiles.
He turns around exposing his ass to Marc. He pushes Marcs face into his ass and i see, that he is licking him from the tip of his cock to the center of his asshole.
Im amazed he hasn't screamed at seeing me. Does he get turned on when people see him like this?

Marc stands up and takes his shorts off showing his slightly smaller cock, 6 nches btw ;).
He mounts Sis' ass and rams away with him. Sis intentionally lets out loud moans that im sure the neighbors would hear....which reminds me, they might be looking at me and Lisa looking into this house...

For about 10 minutes, they've just been ramming that asshole. Marc pulls out and lets Sis suck on it for a while tasting the cum off his cock.

Sis turns Marc down with his ass facing the Ceiling. Sis turns around so he's facing the opposite direction of Marcs face and forces his long cock into Marcs asshole.
Pounding and Pounding. Moaning and Moaning. I feel my panties are soaked with cum just from watching this.
Sis is at climax, he cums in Marcs ass hole and then pulls out to let it drip from his asshole down to his mouth.
Sis turns around and licks up what remains and spits it into Marcs face.
Marc puts Sis down to his cock and begins cummung without even stroking it.
A huge facial that explodes onto Sis' face covering everybit of canvas.
They relish in this for a while before getting dressed as boys again.

They kiss for a while before Marc leaves in his car.
I knock on the front door and wait for Sis to open it. Instead i hear Moaning again.
We're is Lisa?
I go to the Window again and "Oh you fuckin slut" i say while shes being fucked by Sis.
