Take Kelly and bring Sarah.

You grin at your sister. "Field trip time. Wear that tiny skirt. No panties." She looks shocked, but quickly get re-dressed. She follows you out and both of you arrive at Kelly's. Her husband opens the door. You introduce Sarah who asks to come in. He lets both of you pass. Kelly enters the room. You beckon her over. As you do, Sarah ties her husbands hands behind his back with zip ties. He pulls away but she shoves him onto the couch. You bend Kelly over the coffee table.

"Grab the remote." You tell her. She turns everything on as Sarah puts in a DVD. A scene comes on where a man's wife is put up as collateral in an ill fated poker game. The winner has her sitting on his cock as he has her tell the other players she loves taking his cock in the ass. You pull up Kelly's night gown. You grab her hips, press into wet slit, and thrust. "Ooohhh, like that, baby? Feels good, doesn't it?" She looks shamefully back at you.

"Uh...Uh...W-Why...? Mmm...! Why are you.... fucking me....Mm!" You start fucking her harder. "Aah...! Aaah! Uuh....Uuhh...! Mmm! Oh my gosh....Uhh!" She looks at her husband. "Don't.... don't watch....! Uh! Uuhh!" You pull her around beside him, putting her on her hands and knees. Sarah unzips his pants, rubbing his now hard cock. He turns away from Kelly, watching the porno.

"Why.... Why are you moaning...?" He stammers. "You say you don't want it....but you're moaning...!" He glares at her. "Is it the porn? Do you get horny thinking about being used like that? Hm?! That someone else would take you? You do, don't you...?! I hope he fucks you in the ass, too, slut!"

You grab her hair. "Did you hear that, Kelly? He'd just let me use your ass however I want...." You pull out and begin squeezing your dick into her tight butt. "Ooooohhh..... Oh yeah....! Mmmm...." You begin pumping in and out. "He's the one just letting this happen.... thinks you're just a dirty slut...! Tell that asshole you like it.... you want me to fuck you in the ass, Kelly...?! Hmm?" She looks over at her husband.

"I-Is this what you wanted...?!" She asks in disdain. "You didn't even put up a fight...! Mm! Mm...! Not for your own wife.... well he deserves this then! Mm! Ahh! Aahhh...! Ahh.... Yeah! Uh huh! Do it...! Fuck me! Uuh! Unnhh! Fuck that tight butt...! Mm! Unh! Give it to me...! I'm you're helpless bitch now....Uunh! Uhh! Oh God....Ahh!" She rocks back against you as she moans. Sarah looks at him, shaking her head.

"You gave up.... that easy? So fucked up man." She gets down by the wife. "Hey slut. My brother is going to fill your ass soon. Pump his huge load up your violated butt.... he's got you begging for it!" She looks at you. "About ready?"

"Yeah...! But.... shove her head in his lap...! She gave in easy, too. Shove her head onto his cock! **** it down her throat....!" Sarah forces it into Kelly's mouth, shoving her head down, making her deep throat it. You pound her as hard as you can. Her hubby tenses up. Sarah lets Kelly up for air as he sprays onto her face. You grab her hair, pulling her head back as you cum hard.

"Aaa..! Aaa...! Nnnmh...Uuh! Huuhh...." She gasps, looking up weakly at her husband. "Uuuh...Uuuh.... you.... you came...? On.... my face....?" You pull out.

"Keep the porno. Maybe you two can use it to spice up the weekends." You grab Sarah and head for the door.
