What's next?
A Teaser
You waste no time. Both of you were near bursting with desire for one another, the unpleasant interruption all but forgotten now.
Pulling your bound sister to the center of the bed gaze over the sinful feast before you. No...not a feast. A delectable smokin hot little snack. The feast would come later, once Fiona was restored. In the meantime though...YUM!
Fiona is looking right back at you with a thirst that easily matched your own. "What are you going to do to me?" She asks breathlessly.
"Anything I want." You shoot right back.
This was the answer she wanted to hear.
With no hesitation whatsoever have her pinned down, her steel hard stiffy in your mouth, and are bobbing up and down like a man possessed.
"Mmmmmm...nlrmmmmmm..." You suck her cock hard and fast and plenty sloppy. The plans you had for it required a liberal application of saliva.
"Ohhhh my GOD!" Fiona gasps as her little body stiffens to your intense oral attentions. "That's it little brother, suck my cock baby. Ohhhh fuck you're good cock sucker Jesse...so good."
Her words were ambrosia for your mind and ego. Fiona thought you were a good cock sucker? A strange pride swells inside of you. It also spurs you on. For your big sister you didn't want to be a good cock sucker, you wanted to be the best!
"Mmmmm! Nummm...slrrmmmmmm." You hum hungrily. Her teeny wang sliding easily all the way in and out of your mouth. You can't help but wonder what it might be like if Fiona was normal right now. Could you even fit that monster into your mouth? You weren't sure but you knew you'd love to try.
"Ohhhh Jesse!" She moans. She was getting close already. Fiona right now had no size and no stamina. You were loving this, loving everything you were doing and had done with her, but her limitations were getting frustrating. It wasn't her fault of course. You would make the best of it.
Opening your mouth you let her pecker pop from your lips. You smile up at her and chuckle. "Getting close?"
With a face flushed with passion she nods. "Uh huh. Sorry Jesse." Her back arches, thrusting her magnificent breasts upward, and you watch her struggle to tamp down the nut that threatened to overtake her. "Uhhhhh."
You kiss her adorable little balls. "It's okay baby. It's okay."
Kiss...kiss...kiss... You smooch all around her tight little scrotum. You smell it, you nuzzle it, you suck it and taste it as you give her hair trigger penis a moment to settle. Wrapping your lips around her entire ball sack you very lightly suckle them, juggling in your mouth with your tongue. The sheer pleasure you see expressed on your sister's beautiful face made you feel so damn good.
Reaching down between your own legs you slip a hand into your shorts. With two finger you play with your own balls. Mmmm. Then you press and rub into your taint. Ohhhh! Then finally begin to tease your virgin anus. Woah! That felt...good! You'd thought about butt stuff but never acted on it. That was going to change tonight.
With growing impatience you return your mouth to her dick and your hands to her her writhing body.
Slurp, slurp, slurp. Up and down you go slathering Fiona's miniature dick with a heavy coating of spit. Your left hand massages her tit as your right slides between her legs to tickle her very wet tight slit. Fiona moans wildly and squirms in her bonds. She wanted to be all over you right now but you had all the power here. She would have to wait and do what you wanted to do, though she wasn't going to have to wait long.
Kneeling up beside her you pull your shorts down to your knees while keeping her cock in your slurping mouth. Then, sitting back, you pull the shorts from your body and toss them over your shoulder.
Fiona is whispering to you. "Oh my god. I love your body brother. Oh god I want to feel you. I want to be inside of you. Oh Jesse. Oh god Jesse please."
As if you were mounting your bike you throw your leg over her and stradle her tight lean tummy. She tries to sit up to kiss your stomach but you gently push her back down again. "Ah, ah, ah! I'm in control...this time."
She smiles and nods excitedly. "Yes! Yes Jesse. You're the master today. But...um..."
"But?"
"But...don't...um...let me cum inside you. Please. I want to be...powerful when I breed you. I want to plant my seed deep."
You play with her tits, one in each hand, as you cannot help but chuckle. She really thought she might be able to knock you up. She was adorably weird. You nod. "Sure Fiona. Anything for you."
Reaching back you quickly find her rock hard dick. Throwing caution to the wind you press it straight up against your asshole and lower your weight. "Anything for yooou!"
Her saliva coated cock slides right in. It is the strangest sensation of your life as you feel her slick stiffy enter in through your rear exit. It went in...a lot easier than you thought it would. Being your first time you'd expected pain or discomfort or something. There was none of that. Oh...oh wow. You feel her hard organ as a part of you now. Fiona was inside of you!
"Ohhhhhhh!" Fiona's eyes roll back as she is momentarily overwhelmed by the bliss of entry.
You sort of quiver a moment, looking off into space, a goofy smile across your face. Oh...oh my....oh that felt...good. That felt...REAL GOOD! THAT FELT REALLY FUCKING GOOD!
"Unghhhhhhh!" A low growl rises up from deep in your chest. You sit heavily down into her, grinding your ass against her pelvis, getting her as deep as you possibly could. Fuck...you wanted more! More! Grinding forward and back you are seeing stars as the rock hard petite peen prods around within you. "Ohhhh god yes! Fiona!"
"Jesse! I'm inside you!"
"Ohhhh god...fuck...oh my god!" You couldn't form the words to express how great this felt. "UNGHHHH!"
Lifting your weight an few inches you slam back down, shaking her small body beneath you. Then again and then again. You slowly start to ride your older sister, pushing down hard each and every time to get maximum penetration.
"Holy shit, holy shit, holy shit. This feels so good!" Leaning forward you grip her slender shoulders and continue to ride her cock. "I never thought it would feel this good. Unghhhh....fuck."
This was music to Fiona's ears. She is already breathing heavy and has a cute blush across her cheeks and nose. She looks at you with a look of such joy and a deep yet perverted pride. "That's my boy. Ride your sister baby. Unhhh. That's my boy!"
'My boy' she said. She called you her boy. You liked that, you really liked that. You keep riding her in short hard thrusts and stopping to grind here and there. Your own cock bobbed between your bodies harder than it had ever been before. A steady stream of crystal clear precum oozes steadily from the tip.
In and out her cock plunges. Occasionally it would brush and tease against places that took things to a new level. But only occasionally. She was so small, so slender. It felt amazing, but...lacking. You couldn't help but wondering what it would be like to feel...full.
"Come on baby." You moan. "Fuck me"
She does her best to thrust back up into you. "My beautiful baby brother. I knew you'd love cock, I just knew it. I love you Jesse...I love you so much."
Fuck that made your heart feel good.
And yet...
...yet...
...it wasn't right.
This sweet honest expressive little creature was only half of your big sister. You wanted so badly right now to have the whole thing. You wanted to see that fire in your sister's eyes as she held you down. You wanted to be the one being bound and used. You wanted HER to be in control. What was happening right now was an inversion of the natural order. You wanted her to tease you and call you her slut and say you were her good boy and anything else she wanted to call you. And, you honestly weren't sure if you could handle it, but you wanted to feel her long thick cock inside of you right now. This was wonderful, magical, incredible...but it was a teaser of the real thing. You wanted the real Fiona.
You pray harder than ever that when the virus runs its course Peg can restore her to her former glory.
"Fuck me!" You say again more forcefully.
Fiona, given her bindings and lack of strength, does her best. She tries mightily to slam upward as you came down like a ton of bricks on top of her.
"Ungh...unghh...unghhhhh...uhhhhhhh!" Your moans escape you uncontrollably. You were feelings things both foreign and oh so natural, and they were all incredible. More...more...more!
You watch your sister's face twist and flinch. She was close, really close. DAMN IT! You were just getting going!
"Uhhhhhhnnnnnn!" She lets out a long high pitched whine. "Jesse!!!"
God, not yet. You wanted more. You felt like something had been building up. She had roused something that she wasn't going to bed down again. It wasn't her fault though it was frustrating.
"Not yet, come on baby. Unnnghhh."
Slap! Slap! Slap! Slap!
You power bottom down at her as hard and as deep as you could for as long as you possibly could. You wanted enjoy every last second you could of this. Her breasts bounce and quake to your impacts
Fiona's body shudders, her face is a mask of restrained bliss as she did her best to hold back at the edge of release. "Jesse! I'mmmmm unghhhhh gonnnnnaaa..."
Being a man of your word you don't let her creampie your ass. At the last possible second you let her slip out of you. The sudden emptiness was...awful. Sitting back you lay your own larger cock over top hers and stroke them both together, using your rather impressive amount of precum as lube.
It only takes a couple strokes and Fiona is letting loose.
"OHhhhhhhh!" She cries out. Her teeny todger flexes and spasms and spews for a few small gouts of jizz.
You stroke it lovingly and tenderly, pressed hard into your own dick, and milk out ever last drop she had.
She finally lets out a long satisfied sigh.
Looking up at you her face slowly shifts. You tried to hide it but she saw the disappointment in your eyes.
"I'm sorry." She says softly.
You give her a warm and loving smile. "It's okay. You were wonderful Fiona." Sliding down to lie beside her you take her in your arms and cradle her head and shoulders. Fiona leans her head into your chest and closes her eyes, secure and safe in the arms of her brother. You kiss her forehead. "Ohhh, that was incredible. Ohhhh my god Fiona. That was so good. Wow."
Your backdoor glowed with a pleasant feeling that emanated out from it. You just knew this was but a tiny taste of the joys you'd be feeling in the future. For the time being however, it was bliss.
"I love you Sis." You hug her harder and kiss her once more.
Fiona coos happily and nuzzles deeper. Whispering every so softly she sighs. "That's my boy."
