What's next?
Hey Zoey
All three of you freeze in spot. To say you were caught in a compromising position didn’t even come close to describing the situation. You were on top of your big sister and balls deep inside of her. Your naked little sister had her face nestled up in your ass and taint. The smell of cum still wafted through the air from your monster load and both of your sisters still had traces of it on them.
From under your butt you hear Elsie say. “Oh…uhhh. Hey Zoey. You got back quick.”
“Wha…what’s happening here?” You hear Zoey’s bewildered voice answer. “What…what are you doing!?”
Fiona looks up to you then back over to Zoey. “What does it look like we’re doing?”
Not picking up on your sister’s sarcasm she answers. “It looks like you’re havin sex! Like…with each other!”
Fiona can’t hide a little smirk at Zoey’s charmingly genuine, if ditsy, answer. You look back to see Zoey standing there with two bags groceries at her feet, her big blue eyes as wide as saucers.
Elsie wriggles free and is quickly on her feet stammering to her friend, her face from nose to chin and cheek to cheek still gleaming wet. “Zoey! It’s…it’s not what it looks like. Uh…we…we were just…uhhh…oh boy.” She looks to you at a loss as to what to say. You just shake your head. You were caught with your dick in the honeypot, what the hell could you say? “Oh Zoey.” El bemoans. “You must think us terrible!”
“Don’t put words in her mouth Elsie.” Fiona says right back. “If she’s going to stay here she ought to know.” You go to pull out of her but her legs lock around you and she glares up at you. “Don’t you fucking dare.” Looking back to Zoey she says not simply with zero shame but with actual pride. She actually looked happy to be revealing the family secret to somebody. “Most families love each other, we just take it an extra step. Our love is physical…” Her pussy clenches tight around you. “…as well as emotional.”
“Oh.” Zoey says, still overwhelmed by it all. The fact she wasn’t running for the door in terror was a good first step.
Fiona pulls you in and whispers in your ear. “Let me take lead for a bit.” With that she twists then turns you over so that she was now on top riding you. Rising up she boldly stretches her long gorgeous body to display it in all its glory. Zoey’s already wide eyes get even bigger as she sees Fiona’s huge hard cock.
“What’s that!?”
Fiona smiles and gives it a stroke. “That’s my cock darlin. You like it?”
“Uhhhh…it’s…it’s big!”
“The biggest.” Fiona winks.
“But…but girls don’t have…those!”
“Some do.” Fiona replies matter of fact as she smacks it into your belly. “I do. Most of the women in our family do. Pretty rad, huh?”
“R-rad?”
Elsie is a bundle of nerves, a lifetime of keeping secrets all coming to a head at once. “You see…we, they, we…uh…there’s a mutation and…uhh…”
“We’re just the way God made us.” Fiona cuts off her babbling again. “Perfect.” With that your big sister slowly begins to ride you up and down. “Ohhh fuck.” She sighs happily. “Those pussies out there in the world couldn’t handle women like me, so we fuck each other. Just looking after each other darlin, like any good family does.”
“Looking after?”
“Besides, Jesse is such a good lover. Why wouldn’t we fuck?”
“But…but…you’re…his big sister.”
“Damn right I am.” Fiona beams proudly as she traces a finger down your chest. “And his sisters look after him real good.”
You beam right back as your hands glide up her body to cup her full heavy breasts and stroke your thumbs across her nipples. “I love you.”
“Love you too baby.” She strokes your cheek. The intense ferocity had cooled between you with Zoey’s interruption so as not to scare her off, but the passion burned just as hot. Peering back over to your house guest she waves Zoey forward. “Come here darlin, we won’t hurt you.”
“Nobody will touch you.” Elsie swears to her friend. She wanted to hug her but held back from touching her. “This is just between us. Sorry you had to find out like this. We’re terrible. We’re just terrible.”
“We are not!” Fiona stops her there with firm Bailey pride. “Don’t ever say that Elsie. We are a fine family. Come here Zoey.”
Zoey looks around to each of you weighing up what to do before hesitantly stepping over the fallen groceries to stand where Fiona indicated. Elsie follows close by her side, again without actually touching her.
Patting the floor at her side Fiona says. “Right here.”
As if hypnotized Zoey lowers down to kneel at your side. Her big blue eyes drink in everything. They pan along your body, linger on Fiona’s schlong, then scan up your sister’s statuesque physique. Elsie kneels beside her, her dark gaze locked on her best friend with obvious worry.
Fiona continues to ride, slow and easy, her dick swaying gently with the rhythm. “Mmmm. Ohhhh God that’s good. Family sex is the best sex.” She sighs before addressing Zoey again. “Everything go okay with your asshole Dad?”
Zoey nods. “He wasn’t home.”
“Good.” Fiona says. “You’ll be safe here. Don’t you worry about him anymore.”
“You’re safe here.” El echoes. “I swear it.”
Zoey nods again. “I know.”
“Thanks for picking up dinner.” Fiona says, motioning to the torn bags.
“No…no problem.” Zoey whispers. “Happy to…” Her voice fades off, her eyes still glued to you and your sister.
“We’ll pick that stuff up later.” Fiona smiles as she returns her attention to you and starts riding a little faster. “Mmmm fuck that’s good. If you could excuse us darlin, we weren’t done.” Planting her hands into your shoulders she rides you harder still. “Ohhh yes!”
“Ohhhh God!” You moan at the feel of her exquisite pussy.
“Um.” Elsie looks at you, her mind pulling in two directions. She wanted so bad to stay and continue the threesome yet she also wanted to look after her friend. Looking back at Zoey she says. “You can…you can go up to my room if you want. I’ll be up in a bit. I…I can come with if you need.”
“You…want to stay here?” Zoey says in a hushed voice. “With your brother and sister?”
With a guilty look Elsie nods. “Yes. This is just how we are Zoey. I’m so sorry. If you don’t want to stay here after all I totally understand. Just please don’t tell anyone. I’m so so sorry.” She takes her friend around the shoulders. “Nobody will ever touch you sweetie. You are safe here. You never have to take part in any of this! Ever!”
Zoey had a surprise of her own though. With a nervous glance toward Elsie she asks in soft voice. “But…what if…I want to?”
