Jack's Adventures/Be the responsible brother and explain you shouldn't be doing anything
"Lexi, please don't do this," you turn your head away.
"Why?" She pouts, "you said you loved me."
"I do love you," you turn back to face her, "but we're brother and sister we aren't supposed to do stuff like this."
"But I like kissing you," tears begin to streak down her cheeks, "and it felt good when you touched my fairy."
"It felt good for me too," you reach up to wipe her tears, "but it's wrong, I could get in a lot of trouble."
"I won't tell anybody," she sobs, "I don't wanna get you in trouble."
"Lex..." She interrupts you again.
"You have to do it," she gives you a determined look, "you said you would do anything, if you don't I'm telling Mum."
"What? This is what you're going to make me do?" You look at her shocked.
"Well, I was going to ask you to do my homework but I wanna do this instead."
What the fuck is happening? Is your baby sister really blackmailing you? You can't believe she would do this to you. You think to yourself 'why am I not taking advantage of this? Here is a willing girl begging me to do things with her, a very cute girl at that.'
You decide to give her what she wants, what you both want really.
You release your grip and lower her to you so your lips can meet again, your tongues duel as your hands grasp her butt. You lie there making out and you slide your hands under the waistband of her pyjama bottoms, go further and slip your fingers under her panties too. She begins to moan and twitch under your touch, her skin was so soft and smooth.
"Jack," she breathed out as she broke our kiss.
I reached for my phone to check the time, almost 7:30, there was an hour and a half before Mum would come back, hopefully.
"Stand up Lex," you smile at her and she nods and complies.
You kneel up next to her and grasp at the hem of her pyjama top and lift it up, she raises her hands to help as it clears her head. Your baby sister is standing in front of you topless, she has no breasts just puffy baby pink nipples. She has her arms at her sides not hiding herself from your gaze, You reach out and place your hands on her sides.
Your thumbs lightly stroke over her stomach, she's so slim your thumbs are almost touching. You slowly slide your hands upwards towards her chest, when your thumbs make contact you feel the slightest movement. Lexi has the tiniest amount of swelling indicating the growth of her breasts, you want them badly, you shoot forward and capture her puffy nipple into your mouth.
Lexi gasps cutely as you suck on it, you reach for her other nipple and gently twiddle it between your thumb and forefinger. You feel them begin to harden and you hear her moaning, her hands encircle your head, hugging you close.
"That feels super nice," she moans out.
With your free hand you slide it around her back and follow her spine down into her panties, you grasp her soft cheek kneading it like dough. After a few moments of that, you reach further down and curl your finger to rub against her puffy pussy lips. She lets out a gasp and jumps when she feels it. You nestle your middle finger through the valley between her lips. You want it so badly, reluctantly you slip your mouth off her tiny nipple and pull your hand out of her panties, she groans in disappointment as you lie her down.
"Can I take your panties off?" You ask, this time you want her permission to see it.
She brings her hands up to her mouth making herself look almost bashful, she simply nods in agreement. You grab at her waistband and slide her pj's and panties down together, you pull them off her little bare feet leaving her completely naked before you. Your mouth was growing increasingly dry and your cock was raging as you look her over. You can feel the precum oozing out freely coating your boxers.
You grasp her lithe ankle and bring her little foot to your face, since she hadn't long had a bath there was no smell at all. Her toenails were neatly trimmed and unpainted, she giggles and squirms as you suck her big toe into your mouth.
"That tickles," she laughs and tries to pull her foot away.
You sit and worship her tiny foot, sucking her toes, licking between them and kissing her soft sole. You could do that all night but time was short, you drop her foot and grab her thighs and push her legs apart. You slide your legs up her towards her pussy and place your thumbs on her plush lips and spread her open.
"You're so cute Lex," you smile up at her and you see her cheeks grow pink.
You move your face closer to her and just look at her pussy, it's so pink and tight looking, you stick out your tongue and run it from just above her butthole and up to her clit, she squeaks and shudders as you do. You're a little disappointed that there's no real flavour other than skin. You flick your tongue over her where her clit is hiding and draw it into your mouth sucking it hard through the hood.
Her legs lock around your head as you suck her, you reach with a finger and rub over her lips too. It doesn't take long before you feel wetness growing on your finger. You loosen her leg lock and lean back to look, you spread her pussy and watch as a thin line of her juice leaks out of her. You run your finger through it and immediately bring it to your lips.
She tastes so sweet, a tiny amount of tang and bitterness but so very sweet. You drop your face back down and slipped your tongue as deep inside her as you can to get as much juice as you can.
You can't take anymore and pull away from her to quickly strip naked, Lexi looks a little scared as she sees you shuffle closer to her.
"Don't worry Lex, I'm not gonna hurt you," you try to assure her but you don't think it's working.
When you're close enough you lower yourself on top of her and press your cock against her pussy, we both let out a moan at the feeling. You weren't going to fuck her that was a certainty, you just planned on rubbing against her and make you both feel good.
Lexi is small enough that you can rest your weight on your elbows and not crush her, you lean down and kiss her again as you slide your shaft between her puffy lips. She's growing wetter and wetter, at least you think she is, it could be your precum too. You move together so well you're already on edge, you're both moaning in each other's mouths and Lexi wraps her legs around you.
"Jack, something's happening," Lexi groans breaking the kiss, "your thingie is making my fairy feel super super good."
"Call them cock and pussy," you breath out as your thrusts grow stronger and more erratic.
"Your cock is making my pussy all mushy."
You try to hold on since you want to make Lexi cum but it's hard, hearing your innocent baby sister swearing, especially those words had you ready to explode.
You can't hold it anymore and grind hard against her pressing your stomachs together. You grunt out as your balls erupt for the third time of the day, in your mind you realise this is the second time you've cum on Lexi. That's the thought that makes this orgasm seem stronger than the others.
Your arms and legs were feeling weak as you come down from your orgasmic high, you slide off Lexi and lie next to her breathing heavily.
"You peed on me again," is all Lexi says as you stared up at the ceiling.
You can't help laughing at that which makes Lexi laugh too.
"Sorry about that," you reach out to her and stroke her face, "I really do love you, Lexi."
"I love you too Jack," she smiles.
"Let's go clean up before Mom comes back."
"Okay."
You both get to your feet and you grab your clothes and make sure the coast is clear, it is so you quickly but quietly run to the bathroom. There's no time for a shower or anything so you pick up a washcloth and scrub you both clean. Once you're all clean you pull on your boxers and help Lexi back into her pj's then sneak back to your room. You open up your window slightly and lie back down with Lexi.
"Did you cum Lex?" You ask.
"I don't know, it felt super good but I can't squirt like you."
"Well, I promise I'll make you cum next time."
"Can I sleep with you tonight?" She asks looking at you with puppy dog eyes.
"I don't mind but Mum might," you explain and check the time, it's a little after 8 pm, "let's get under the covers maybe if we're both asleep when Mum comes back she'll just let you stay."
"Okay," Lexi quickly gets under the covers, "come on get in."
"Hold your horses," you laugh and change your boxers.
Since Lexi is here you think it would be better if you wear clothes, after all, it would be hard to explain to Mum if she sees you sleeping naked with Lexi. You pull on an old pair of pyjamas, your's aren't as cute as Lexi's they're just plain blue.
You turn off the TV and the light and climb into bed next to her and you both snuggle each other close, you wrap her in your arms.
"Goodnight Jack, I love you."
"Goodnight Lexi, I love you too," you give each other a kiss and close your eyes.
