A Sister Sandwich, with Double Cream Filling

Your little sister Elsie then begins undressing, peeling off her shirt and then her long dress. This was happening. Your mind was stunned and scared but your body was beyond excited, you were so horny!

Fiona slides her hand down your body, she stops to grab your tender breast roughly. "Ow!" You whimper, this only brings a smile to her face. She continues her hand's journey downward, soon finding your garden of Eden. She slides her fingers up and down your very wet, very ready pussy.

"Holy shit are you wet. She is ready for you Elsie." Fiona grins. "What a little slut, you're turned on by this. Ha ha ha!"

Elsie had taken off her underwear and was rubbing her rapidly hardening meat. She continued to look over your body with unvarnished jealousy. Seeing this ugly emotion on your little sister was heartbreaking. If this is what it took for her to feel better, so be it. You open your legs, providing an area for Elsie on the bed.

This amuses Fiona to no end. "That's it you little slut, open wide for that big cock. Ha ha ha!"

She continues playing with your pussy and clit, your body was abuzz with sexual excitement. A little moan escapes your lips. Fiona leans over and with zero subtlety or gentleness sucks hard on your right breast and nipple. "Ah!" You cry out. Pulling her mouth back your tits escapes her lips with a loud pop!

"Fuck. She tastes and smells so good." She looks to her little sister and prods her once more. "Imagine the boys you could get with a body like this, eh El? You'd be so popular."

Angry resolve solidifies on your little sister's expression. Elsie crawls onto the bed, kneeling on the mattress between your legs. She holds her huge ten inch in one hand, her other hand plants beside you as she readies to enter you. She is avoiding all eye contact, keeping her eyes firmly on your body instead. She suddenly pauses.

"Shit, I forgot a condom." Elsie swears. "Fiona, could you go get one for me?"

Fiona shakes her head, she fades away from the two of you to watch the spectacle. "Just fuck her raw El, fuck her bareback. Let her really feel you little sister. You can always pull out." She continues her goading. "Look at her, she's so perfect. She's going to make some guy so happy with that slutty little body. She'll get to go out with all the guys she wants, no secrets for her. God, could you imagine it Elsie? To be so pretty, so normal. And you know she'll be Mom's favorite, no doubt about that. She'll get to go off and start a family, what happy life she'll have." Fiona then adds the piece de resistance. "You and I, we'll be stuck with each other forever. Just Fiona and Elsie. Good thing we have each other, hey Sis?"

Elsie's eyes narrow as Fiona masterfully stokes the flames of her sister's deepest ugliest darkest feelings.

You let out a trembling sigh. You wanted Fiona to stop, yet you didn't want her to either. You were so conflicted. You were utterly overwhelmed and didn't know what to say. You spread your legs even wider and grip the mattress. You were so excited yet so scared all at once. You had no idea what this was going to be like.

"Elsie? Elsie?" You say to her, but she isn't listening.

Your little sister pushes into you. Just for a moment the feeling is incredible. A much needed feeling of fullness where you felt so empty before. It very quickly turns to pain as her huge cock stretches you far beyond what you thought possible and pushes a bit too far into you, tearing your fresh hymen.

"Ow!" You cry in your new girly voice. "God! Ouch! Fuck! It's too big! Fuck! Ohhhhhh...that's big Elsie..."

Elsie freezes. She is over you missionary style, her hands to your sides. Her head is bowed and you get a definite sense that she is having second thoughts. You whimper as you spread your legs as far as you can and desperately try to adjust to her girth. Your breathing is shallow and rapid.

Just then you see Fiona kneel on the bed behind Elsie. She was nude and at full mast. She positions behind Elsie, obviously about to fuck her doggy style as Elsie fucks you missionary. It would be a sister sandwich with Elsie in the middle.

Elsie's head snaps up and her eyes widen in surprise. "Fiona! Wait! We shouldn't...Owwwww fuck!" Her face scrunches up in a combination of surprise and discomfort as Fiona enters her.

Fiona has all the subtlety of a bulldozer and buries herself in Elsie which in turn causes Elsie to bury herself in you! You were not ready for this as she goes balls deep in your fresh young pussy.

"AHHHHHHH!" You scream.

"Oh Jesse!" Elsie gasps, she suddenly seemed to snap out of her vengeful mood. "Oh Jesse, fuck, what are we doing? It gets better Jesse. Just hold on, okay?" Fiona has a wicked grin as she begins driving into her sister, which of course causes a chain reaction into you.

Elsie's concern is soon consumed by the pleasure she was experiencing as she had both of her sexual organs stimulated to the limit. "Oh my god! You're so tight. Jesus!"

You are just holding on for dear life. You grip the mattress and cry out. It takes some time but Elsie was right, it began to get better. Much better! The pain was slowly transforming into full satisfying pleasure, the transition almost seemed impossible yet it was happening nonetheless.

Fiona is cruel and mocking, only now did you truly realize the depths of your older sister's malevolence. "That's it Elsie, wreck that slut's little cunt! Stretch that fucking cunt!"

Elsie was overwhelmed by what she was experiencing. All she could do is moan in pure carnal bliss. As it all really starts feeling good you feel something build within you, suddenly, almost without warning. A feeling spreading from your groin and pulsing out in waves through your body. The orgasm hits you like a tidal wave. You scream in unadulterated sexual release as the feeling owns you body and soul.

You hear Elsie cry out. "Oh god! She's tightening up. Oh fuck!" You wished so bad that they would stop or even just slow down for a second, it was all just too much. The fucking continued unabated.

Elsie cries out again. "Fiona...fuck...stop....I'm close..." You can feel your little sister trying to stop, to pull out, but Fiona was bigger, stronger, and had all the leverage. She just keeps fucking Elsie with a steady heavy slap slap slap as they came together.

Elsie is ****. "No...God! I can't....fuck...STOP! Fiona! I've got no protection! Ohhhhhh..." You see as she clenches her jaw, trying to fight off the inevitable. It is no use. "Ohhhhhhhh God! Ohhhhhhhh Jesse! Fuck!"

You feel as she unloads inside of you, she is **** balls deep once more as Fiona drives forward and holds her there. Elsie clings to you and you hold her in return as she pumps her hot creamy seed deep inside of your very fresh and very fertile young pussy. You feel each pulsing spasm as you are filled with a gooey warmth. This sends you over the top once more as well. As you lie with her on top of you, you are both panting and sweaty. "Ohhhhh Jesse...I'm sorry..."

Just then Elsie shudders as Fiona pulls out of her. You feel as Elsie's cock is pulled unceremonious out of you, a hot stream of jizz running down to the bed, only to be instantly replaced by another bigger cock. You didn't think you could feel any fuller, but as Fiona spreads your cunny lips wide with her hands she rams herself into you. That pain of being stretched to the absolute limit returns once more. Dear fucking lord she was big! She was fucking huge! It is a mild consolation but it was good to have Elsie's creampie there to provide extra lubrication.

Elsie shimmies up a bit, bringing her knees up over your legs and beside you, sitting on you like she was about to ride you had you still been a male. She was collapsed on top of you, holding you close. She held you and stroked you as Fiona ravaged your pussy.

She pushes in as deep as she could. She was just so huge, she was reaching places you didn't think possible. It takes her a bit to work up to it but soon she is fucking you hard and fast.

"That's it you fucking slut, take that huge cock. You might get a normal life but we'll make good and fucking sure you are fucking wrecked for any man that wants you! We will ruin you! You fucking slut!" The ferocity of Fiona's attack making it clear that Elsie wasn't the only one with issues around you being a girl. "God you tight little whore, that's fucking good. Yeah!"

Fiona commences to fuck you silly. While not nearly as nice as Elsie you eventually do adapt to the beastly appendage. She sends you into fits of ecstasy again and again and again. You lose all track of time and place as you simply hang on and endure repeated body wrenching orgasms. Elsie continues to hold you and try to comfort you.

Finally, mercifully, you feel Fiona bust her nut inside of you. She stays buried so very deep inside of you until her climax completely subsides. She lets out a long satisfied groan. "Yeaaaaahh! Good little slut..."

You hear Elsie whisper. "Oh my god. What have we done?"

You lie there, collapsed, unmoving. Staring at the ceiling in a numb haze. That was fucking...incredible!!!
