Make Britney yours now, deal with Jessica properly later...

Now that the girl’s sense of sexual pleasure is strongly connected to your own you decide to let them feel what it’s like when you fuck somebody. You’re pretty sure this is going to be the final move in making Britney your sex **** from now on, as she will be experiencing her own pleasure and yours at the same time. No other man she’s been with could possibly compete with that and no other every will be able to match the sheer pleasure she’ll get from servicing you, her own brother. You grin wickedly at the thought.

Jessica on the other hand has been on the sidelines the whole time and would experience the whole sensation too through Britney too, but with no stimulation other than what she gives herself. You decide you don’t want that and break the link between the two girls. Jessica will experience the full pleasure from you directly when you deem it to be so, not through her sister.

“I’m hard again because I’m still unsatisfied” you tell Britney who now seems to be fixated on your cock. She looks up at you stunned, but before she can say anything you reach around and grab her firm young ass to bring her forward for the kiss. Her tongue seeks yours hungrily and you slide your hands up her narrow waist and onto her firm pert breasts. You squeeze them hard causing her to gasp then reach back down to slide her tiny blue g-string off.

Getting the idea, she gets off you just long enough to step out of her underwear. Before she can straddle you again, you grab her, spin her around and bring her down onto your lap facing away from you.

Jessica gasps as she realizes what is about to happen but doesn’t move. Instead she watches transfixed as grab Britney’s waist and guide her hips until her soft wet young pussy is positioned over your cocks throbbing head. You move your hips slightly so Britney can feel the head of your shaft rubbing gently against her pussy’s lips and she moans in desire.

“Please John, just stick it in me” she begs softly.

“You won’t be calling me shrimp again after this!” you say forcefully, and with a sudden jerk, you impale her on your waiting pole. Her mouth moves soundlessly as you **** yourself deep inside her and you feel her soft pussy stretch to accommodate your new size. The feeling of entering your sisters sweet soft cunt is amazing.

“Oh My God!” she gasps once she finds her voice again “It’s massive! John’s massive cock is inside of me, and it feels so good!” Not needing anymore encouragement you send a command to your arms and shoulders for strength then holding her firm hips, you psychically lift Britney in her sitting position off of your lap until her feet leave the ground and her pussy only holds the pulsing head of your shaft. Britney writhers in your hold desperately trying to take you back into her, but you hold her there.

“C’mon Shrimp! Don’t be a tease!” she snaps testily “fuck me!”

“I told you not to call me shrimp anymore” you say sternly then ram her down onto your throbbing cock. She cries out feeling both her pain and your pleasure but before she can recover you lift and drop her again. You begin to pick up speed, sliding your sister up and down your giant cock like a fuck toy while she gasps and squeals in a mixture of pleasure and discomfort.

“Oooh! Please… not so fast! Aaaah! It feels…” she cries between moans “please… not so rough! Oh god… yes!!”

“Don’t… call… me… shrimp.. again!” You say between deep thrusts into her and with that you release your hold on her so she impales herself completely onto your engorged pole. She falls back against you taking your manhood completely into her and you feel your cock head slam against her cervix wall. She cries out in pain but the awesome pleasure it causes you is transmitted straight to her, causing her cries to quickly change to moans.

Her hips start to gyrate as she begins to thrust herself onto your dick and you sit back and enjoy the sight of your own blonde slutty sister fucking herself on your pole. Her gyrations soon change to a bouncing movement as she speeds up, bouncing herself up and down on your cock, you can’t help but to reach around her and cup a breast to feel it jiggle firmly in your hand.

As her pace increases, you sense her cumming. She begins ramming herself onto your huge shaft and grinding her ass into your lap, taking all of you in despite the pain she must feel. She tosses her head back as she begin to climax and arches back into you, yelling;

“Oh Shit! Yes! That’s it, Bro… Fuck me like a cum toy! Oh fuck… your cock feels good in me!” she cries “I’m cumming! I’m cumming because my brother fucks me hard! Oh shit, I’m gonna cum!”

Just as she begins yelling you feel her pussy wall contract on your cock sending bolts of pleasure through you. You decide she has earned a treat. ‘I want to extend her orgasm’ you think, knowing this is as much for you as for her. Britney’s eyes bulge as the feeling continues in her.

“I’m still cumming!” She gasps “Bro, you making me cum so hard! Fuck me John, fuck me harder!”

You grab her firm ass and begin ramming into her like a piston. The feel of her slick cunt contracting around your meat overwhelms you. You feel her ass slapping against your pelvis and watch her tits bounce heavily with each thrust you make. Finally you feel yourself about to cum.

Britney feels it too within her own sexual frenzy, and you realize by cumming at the same time, your sister will experience two orgasms at once! You slam deep into her and release. A seemingly endless supply of jism shoots deep into your sister and fills her womb. Britney cries out one last time and falls back against you.

You sit there still slowly sliding in and out of her, as she lolls in a daze against your chest.

“no other..” she whispers weakly “Never another but you…”

You listen for mum, but only hear the shower on upstairs; she probably didn’t hear the shouting. You almost smile outright but then remember Jessica…
