Time to stick a finger up that ass while she fucks
From Create Your Own Story
You slap her ass again, but leave your hand on her cheek as she is bouncing on her brother making various sex noises. Slowly, you trace your fingernails over her butt cheeks, then you slide a finger between them. She's already riding Adam fast and your finger is quite close to his dick which you're trying not to think about. But needs must and right now, your desire to plunge your finger up Kara's tight asshole overrules the desire not to see your friend's cock. So in your finger goes, slowly but surely. Kara's fast movements don't stop, but suddenly she's squealing as she feels the sensation of both holes being filled.
She shrieks "Mmmmm...that's...that's....weird"
You grin and say "Damn right, you naughty girl!" Then you start pumping your finger in and out of that fine ass as she rides and grinds Adam.
Kara's body is bouncing around like a rag doll now, as you push your index finger as far as you can into her butt then hook it up so you help lift her up and down on Adam.
Adam himself is groaning loudly now, and then starts licking his sister's tits all over with wild abandon.
Kara murmurs "This is so fucking hot. Fuck me harder, bro!"
After a minute of hooking Kara's ass, you need more. Out comes your finger, then you grab your cock and line it up to her asshole as best you can as she's moving. She's going to know what it's like to be full now. Kara can now sense what's just about to happen, and as an anal virgin she manages to whisper "Oh, oh, be gentle with me."
You whisper back "I won't hurt you, baby girl. You're going to experience all your senses filled at once. Arch your back, honey." You don't know if that'll help, but it will give you better access without rubbing dicks with Adam.
Kara arches her back and stops riding, while the tip of your cock enters her tight ass. She tenses and groans. Adam can't help but start thrusting his cock up into his sister's pussy. Your cock now feels like it's in a vice, as you push in further but it's so pleasurable. Kara's moans have turned to short whimpers. You thrust a few more times and Kara screams but you and Adam keep on pumping her different holes. Kara is muttering "Uh...uh...oh fuck...oh yes!" in between deep breaths. Finally your cock is buried in her ass and you moan out your extreme pleasure. Kara takes matters into her own hands, and starts grinding around, trying to get used to the sensation of two big cocks filling her holes. Your cock has definitely never been anywhere as tight as Kara's anal passage.
You now start getting to work and thrust in and out of Kara as Adam takes care of the front. You balance yourself by grabbing Kara's shoulders, as Adam has wrapped his arms around her waist. The three of you rock, thrust, moan and continue fucking like never before and your cock starts tingling bad. Kara makes a grunting sound like a tennis player every time you plow into her bum.
