A Special Thrill

“Sorry Fiona, what was that?” You ask as you push your dick deeper.

“Mmmrrrrmm!” She growls with her mouth full of your manhood.

Elsie pulls Fiona’s shirt back over her shoulders and down off of her. “That’s it Fiona, suck Jesse’s big cock.” She kisses up Fiona’s long neck as she undoes her big sister’s bra.

Any worries you had about feeling after the procedure is quickly put to rest. The nerves were working fine, better than ever, you could feel every lick and contour of your sister’s warm sucking mouth. Her nostrils flare as she hisses in and out as she tepidly sucks. Given her supreme confidence your sister was surprisingly terrible at giving head, most likely due to her lack of experience in getting on her knees for anyone.

Elsie continue to kiss and suck as her hands lovingly caress Fiona’s breasts. “God Fiona, you look so damn sexy with Jesse’s big dick in your mouth.” El whispers as she begins nibbling at her sister’s earlobe. Moving to the side she presses her breasts into her sister and flicks her tongue around Fiona’s ear. Then, kissing along Fiona’s cheek, Elsie moves to her mouth to suck the side of your shaft as it slid in and out of Fiona’s lips. Seeing your two gorgeous topless sisters at your feet and servicing your cock was a special thrill unlike any other.

“Mrrmm!” Fiona growls in response to Elsie’s attentions. El was teasing Fiona’s nipples with tiny little pinches. “Mmm.”

Using no actual ****, as that was not Elsie’s way, your little sister cups a hand at the back of her big sister’s head and encourages Fiona to go deeper and faster. “That’s it. Suck it. Suck brother’s big beautiful cock.” El lilts. “Show him how much we love him.”

Fiona sucks a little harder and a little faster at El’s gentle encouragement. You could actually feel Fiona relax more just by your hold on her hair. Still though, she seemed **** and even embarrassed by what she felt was a submissive position. Remembering what she’d told you you decide to change things up.

“Come on Fiona.” You mock. “God you suck at giving head.” You give her hair a tug. “Allison is way better than this.”

Her eyes snap up to meet yours and she lets out a deep feral growl. “Rrrr!”

“El.” You say.

“Yes?” She chirps with a grin.

“Open up. Show Fiona how it’s done.”

Her grin brightens. “Yes big brother!” Leaning in so her face was right next to Fiona’s she dutifully opens her mouth wide. Fiona’s eyes glare over at her as you slip from one mouth to the other. “Mmmmm!” Elsie coos happily as you slip inside, her big dark eyes gazing adoringly up at you.

“Ohhhh damn!” You gasp as your little sister works her oral magic on you. Despite your new and improved size she easily glides right down your shaft and back again in one smooth easy motion. Her tongue swirls and dances over your tip as her supple lips massages your sensitive knob. Again she dives down, the moment you cross from mouth into gripping throat a moment of pure sexual bliss. Holding you deep she simultaneously gulps and suckles at once sending rolling waves of pressure up and down your member. Slapping your right hand slaps back into the wall you gasp. “Fuck!” To say she was good at giving head would be the understatement of the century. She did it as naturally as a fish taking to water and with seemingly zero gag reflex to speak of the experience was off the charts. Watching her suck back up the appendage that was so recently been attached to her blows your mind as well as your dick but only for a moment. Elsie was right, this was you now as surely as your brain or your heart. Your free hand gently rests on El’s bobbing head as your other keeps Fiona firmly in grip. “Mmmm, now that’s how you suck a dick! You could learn a thing or two Fiona.”

“You fucker!” Fiona gripes as she wipes her cummy face off with her shirt. “We’ll see how good you do when I have you on your knees.”

“Better than you I bet.”

“You cocky bitch. We’ll see about that.” She tosses the shirt to the side. “I ought to bite it off…MMMPH!”

Just as El slipped off your tip you quickly change targets and push your now hard peen back through Fiona’s lips. “You shouldn’t bite the cock that feeds you.” You quip to the groans of both your sisters.

Fiona glowers up at you but it was more for show than genuine anger. This time she grabs hold of your shaft with both hands in an uncomfortably firm grip, you catch her smile at your pained grunt. Fiona couldn’t go nearly as deep as Elsie could but using her hands as a guard she is able to work the top half of your cock with aggressive energy. She slurps and bobs up and down four inches for a time before carefully biting down and slowwwwly letting her sharp teeth scrap along the tip of your spit lubed schlong before giving you a stinging little nip at the end. Tilting her head she moves to the side and chomps down into your shaft as she might a cob of corn, not enough to hurt but certainly enough to feel it, then switches to her lips which she then slides up and around to the others side. Opening wide she flicks her tongue all the way back to the tip before jabbing it hard right into the hole.

“Gnngh!” You grunt through your grin.

“Better?” Fiona teases.

“Much!”

She was clearly having fun and so were you.

While this was going on El hadn’t been still. Kissing down the side of her sister she had then unfastened the waist of Fiona’s dress and pulled out Fiona’s hardening monster cock. She wasted no time going down on her sister even as Fiona went down on you. It is not long before Elsie’s dark haired head is bobbing up and down, her head brushing over Fiona’s tits as sucked up to the tip of her thirteen plus inches.

“Mmmm!” Fiona’s hazel eyes flare as El did her thing down below. Even from the short time you’d felt it you knew just how good El was.

You’d eased into this long enough. Taking your sister’s head now in both hands you thrust into her mouth and wrest control from her. In slow undulating thrusts you begin to face fuck your gorgeous blond big sister. Fiona’s hands grasp onto your thighs to give her some control on how deep you went but otherwise you were in the driver’s seat now. Gradually you fuck her sucking lips faster and faster, your cock as hard as steel.

“Yeah. Suck it Fiona! Suck my big fat cock. Fucking suck it you whore!”

“Mrrrrm!” She growls with wild lust.

“Faster, come on!” You pump faster. “That all you got?”

Fiona does her best to keep up as you fuck her mouth like a pussy. If she wanted it rough you were gonna play rough. “Mrrrm!”

“Come on!” You urge as your thrust get harder. “You can take it deeper than that.” With that you sink an inch deeper on the next thrust and then just stay there. Her fingers sink into your legs and her eyes bulge as you take her right to the limit of wretching. “Deeper!” Another inch pushes in.

“MMM!” She hums and snorts through flared nostrils as tears fill her eyes. With two handfuls of hair you hold her firmly.

“A little longer. That’s it. You can do it.”

“MMMMM!” As you hear distress in her voice you pull out. “GAHH!” She gasps as a drool streams from her panting lips down onto El’s bobbing head. She looks up at you breathing hard with a blazing inferno of desire in her eyes. She slaps both her hands into your bare chest and claws down your body. You club her face a few times with your hard wet cock and she snatches at it with snapping teeth. “Rrrr!”

You go to line up for another go but she surprises you by pouncing upward and hooking the back of your neck and pulling you back down with her. It happened so fast you couldn’t maintain your balance. The next thing you knew the three of you were tumbling to the kitchen floor with you on top.
