“Hide in plain sight”

You explain your plan to Cassidy & Carrie and they both smile horny at the possibilities. And you too are proud to be a part of this taboo triangle. It’s as if all of this has awakened something inside of you you didn’t know was there. Perversion, sure everyone has that. But more than that.

The next day you go apartment hunting for a place that will accommodate 3.

Then Cassidy goes to get her first tattoo.

And Carrie takes the first steps to legally changing her name.

That’s the plan. Carrie changes her name, Cassidy changes her image. Well, that’s the plan in a boring nutshell.

In three months time things are progressing nicely. Carrie likes gliding her tongue along her sister’s new tattoo’s as you fuck her in the ass.

In fact, you fuck constantly, like rabbits. You plant your cock in every orifice in the two girls’ bodies and the girls lick each other clean, slurping out your cum and sharing it. This is your life, every day.

When Cassidy comes home with her new dyed hair and Carrie jokes that her sister’s new image is so sexy it’s giving her low self esteem, Cassidy let’s the two of you cum and spit all over her face and take pictures.

When Carrie laments that all she does is paperwork for this stupid name change, you take a sharpie and scribble across her sister’s tits “sign here to be an incestuous slut.” The girls laugh. The Carrie signs her new name “Agnes” then licks her sister’s clit until she screams.

“Why Agnes? It’s not a pretty name.” Cassidy asks one day.

“It means ‘pure’” Carrie answers.

“So it doesn’t apply at all.”

“Yeah, that’s the joke.” Carrie says, pulling down her dress to expose her new nipple piercing for her sister to suck on.

Of course you and Cassidy still call her Carrie. You’re the only ones allowed to know the truth.

Carrie gets a new job as a yoga instructor. Cassidy gets a job as a bartender in a strip club.

When you go out at night sometimes you and Carrie act the couple, cuddling and kissing. Sometimes you and Cassidy act the couple. Sometimes Cassidy and Agnes act the couple.

Watching them smooch in public is a brilliant sight that makes you hard every time.

And of course you keep fucking in every way imaginable. Carrie likes getting double-penetrated. Cassidy likes getting tied up. You like it when the girls reminisce about growing up together.

One night you shove thick toys in Carrie’s ass and pussy while she ties up Cassidy and spanks her as **** for that time Santa brought her the purple bike she wanted instead. That’s a good night.

Carrie finds an old Halloween photo from before you knew the girls, dressed sexy as a black cat in a tight dress and an angel with cleavage. They try to recreate the costumes for you. You jerk off onto the photo. They lick it up. That’s a good night too.

So it’s not due to any deficiency in your sex lives when Cassidy suggests something dramatic. Something both you and Carrie should hesitate to do, although you both agree to it immediately.
