Chapter 40 by Nailedit472
What's next?
Seduction and fulfillment
You know that you should fight it: she is not herself right now, she has no control over her emotions. But you feel compelled to get closer, to do what she wants you to do.
She's a grown-up woman. She wants this. And you too.
-Take off your clothes, honey.- She requires. You hesitate for a moment, but then you discard your t-shirt. When the tissue is no longer occulting your sight, you find your aunt right before you, her nipples no more than one centimeter away from your chest. You're left agape by this sudden vision, but she's far from being finished, as she presses your foreheads together and, with a hand, starts to unfold your belt.

-Aunt!-.
-Ssh.- She blows on your lips: -It's alright. It's alright.-.
Your trousers fall on the ground, followed by your boxers. You shiver as you feel her thumbs pressed against your hips, but you have a real quiver when she starts to brush your abs. You're now naked, with your aunt who just came out from the bathtub that is lustfully touching your body, preparing herself to have sex with you. And, yet, shame and discomfort are as faint as leaves in a rushing stream.

-You're so firm.- She smiles.
-Your mother must be really proud of you.-.
Your heart skips a beat. What to anyone else would have sounded simply as an innocent compliment, it elicites in you a dimension of passion and taboo which makes you quiver in anticipation.
-...Thank you.- You mutter.
-You're, uh, you're beautiful too, Aunt Maddison.-.
-Oh, what a gentleman!- She chuckles; then, her expression becomes serious and focused, and she joins her hands behind your neck, drawing her face even closer. Time seems to be suspended. You part your lips, your instinct kicking in knowing what it's about to come. Only that it doesn't. Maddison drops to her knees, placing her hands on your joints and admiring your erected shaft with a dense transport.
Before you can react in any way, she opens her mouth and engulfs it.

-Ohh!- You moan, having her tongue working experiencedly on it, as she bobbles her head backward and foreward while stroking the base of your penis with one hand. A viscous, whitish liquid composed of spittle and precum begins to ooze from her mouth, but her pace doesn't appear to be distracted by this.

You can't believe it, even if you're seeing it in person, even if you're listening to her gagging noises with your own ears; even if you're feeling it.
Your aunt is blowing you.
Just the mere fantasy would be enough to make you cum, but instead your agitation is so much that, somehow, your dick seems to have become of stone. And maybe it's for the best.
Aunt Maddison retracts, a white thread connecting the tip of her tongue to the one of your penis, and looks up at you with a sultry grin.

-Mmm, you're so big! Now I see why Jessica loves you so much... oh, I wish I had a son like you, Tom!-.
-May I be your mommy for this time, please?~-.
Your member throbs, both for her words and for the grasp of her fingers. W-What's the meaning of this? Does she know of you and your mom? Yes, of course she does, Emily had warned you! You shouldn't be surprised, you shouldn't be... excited. You were so close to end this, you just had not to open the door, you just had to insist a little more in the car, it would have been so easy!
But you didn't. You knew it would have led you up to this point, and yet you didn't.
-You... you can't ask me just like this...- You protest, your soul being mangled by those deadly, lustful eyes looking at you, standing right in front of your cock.
-Well, 'auntie' is fine too...-.
-No... we should... we should stop now...-.
-Oh, what a silly boy!- Maddison jumps up and, with the joviality of a schoolgirl, she guides you inside the shower cabin, pulling your manhood like the leash of a dog.

You follow her, stings of pain mixing with the arousal pumping at each pulse. This gesture has caught you genuinely off guard and you falter on your feet as she takes a flacon of shampoo and spread it on her palms. You swallow a clotted lump when she turns back to you flashing an eager expression.
-W-What do you want to do?-.
-Relax. I just want to make you more... suited.- She places herself behind your back, and then her arms slip between your armpits, smearing the shampoo on your thorax with erogenous massages. The solid warmness of her palms overlaps with the cold humidity of the lotion, resulting in a pinching contrast that makes your muscles tense in little jolts. You close your eyelids, feeling her prosperous mammals pressing against your back and her touches moving more and more downside.

-You're so naughty, Tom.~- She teases on your ears.
-You pretend that you don't like it, but in reality...- She swiftly grabs your dick, stroking it gently between her thumb and index while groping your ballsack with the other fingers. You gasp in reaction and you move your hand to stop her, the surge of pleasure having been so much that you were afraid you couldn't bear it. But, instead, she puts it on her thigh, mocking your pant with her exaggerated ones.

-Mmm! You can't hold your hands away from me, can you???- She furiously asks, jerking both your wrist and your cock. You shudder, your climax is speeding toward a non-return point. Your raving thoughts are almost relieved by the quick finale of this awesome, yet wrong, moment of incarnated fantasy, hoping that if your will has not been able to overcome the temptation, maybe your anatomic flaws will fix it.
But, as if sensing this perfectly, she stops just a moment before it's too late. She makes you spin, and this time she finally locks your mouths together in an overwhelming, passionate kiss, maybe even more intense than those with your mother and your sisters. Your body is now **** by its own serotonin and dopamine, and it's trembling like feverish, drowning your sense of regret under layers and layers of desire and arousal.
You can't fight it, even less win against it; thus, you desperately try to convince yourself, it's not your fault, you really can't be blamed for any of this.
-Where do you want to stick your cock, darling?- She questions, not even slightly embarrassed by the impudence of the words she's using with her nephew. With dry jaws and your heart clasping down your throat, the answer escapes from your lips in the form of a wheeze.
-Your tits...-.
You can't believe you just said that. A smug grin curls your aunt's lips, while with one hand she gropes her own breasts.
-Mmm... you like my titties, right? They're so squishy... so hot...-.
You nod, completely entranced by the vision. She sits on the border of the bathtub, motioning you to step in. You obey. She giggles, then she sways her chest, making her boobs swing like pudding.
-Come on.- She incites you, her tone masking with calmness a fiery desire. You hesitantly graze them, wincing as you do so.
Oh my God, you're really touching your aunt's tits! And she, she's glad you're doing so!
-Do it, Tom. Stick your big hard cock between them.-.
You take a final breath and then you do it. She leans forward, holding onto her arms, while you handle her breasts to slide your trunk in their between, admiring your head piping up rhythmically below her collarbones. The sensation is almost indescribable, it's like having two warm pillows milking your dick, they're even softer than with a pussy. In a sense, since a vagina is still a vagina even if it's the one of a relative, this is even more prohibited, more unbelievable and, therefore, more exciting. This is definitely not how a person should interact with his mother's sister's bosom.

-Mmm... oh, Tom...~-.
The feeling, that sight, your name, it all soon sends you over the edge.
-I'm... I'm about to...!-.
She gets it immediately, and with a swift movement she's back sitting on the board, her digits around your member and her lips swallowing it. You just have a brief moment of lucidity, oh fuck you're about to-, and then the orgasm explodes on the verge of your tip, pumping all your sperm down your aunt's throat.

She goggles, drinking it with loud gulps, not allowing a single droplet to be wasted. Finally, she releases you, looking at you with a happy smile. Your mind, instead, is completely on tilt, like a computer having a crush.
"She has just, she has just, she has just...".
-So, how was I? Have I been good like Kim?- She chirps, nearly giving you a stroke. T-Then you were right, she knows! She knows that you had sex with your sisters! With your mother! And she, she's ok with the idea!
-I... aunt Maddie, I... I don't...-.
-Hey, hey, relax. Sit down for a minute.-.
You know you that it's a bad idea, you know that you should go, but once again you are unable to disobey. Therefore, you lower yourself on a corner until you're immersed up to your neck and, with the help of your aunt's gentle touches, you take courage and stretch your legs.
-Here. The water is warm, it feels good, right?-.
You nod. You are, indeed, comfortable, even relaxed you would say, lulled by the sound of water and delighted by the view before your eyes. Maddison, however, places herself astride your legs, sitting down too and clinging herself onto you. Your floating penis is touching her tummy under her navel, while you can feel her diverted buttocks pressing one on each leg. It's just a matter of centimeters that separates your sexes, a distance so frail that you know any of you two could clear with a simple gesture.

-What are you doing?- You timidly ask. She is brushing your pectorals like she was doing before, and by encircling your back with the other arm she makes her breasts delicately skim your skin. Oh yes, this is what you were missing before...
-I just want to cuddle for a bit, honey. To have a nice chat, between auntie and nephew...- She moves a little, crawling up one millimeter: enough to make you look down in emotion, but that was just her way to tease you, and she has succeded in doing so.
-How is your knee? Still hurts?-.
-No, no it doesn't...-.
-Good. I would be so sorry if your handsome body was ruined for this.-.
-T-Thanks... your body is really beautiful too...- You splutter, taking a deep breath at each of her caresses.
-You flatter me.- She timidly smiles: -It's been years since anyone has given me this compliment. In truth I was afraid... I was afraid that you would find me too aged...-.
-I, I would never!- You reply. Then a wave of embarrassment knots your tongue.
-I mean, s-surely Uncle Mike will tell you this often.-.
A tinge of sadness veils her eyes.
-He does, but... he doesn't look at me the way you did. He doesn't become hard anymore, the way you did. I have felt very lonely until today, Tom. But now... now I'm happy. You made me happy.-.
She leans on and kisses you, her lips trying to wrap yours with rapid but intense pecks. Right now, holed up inside the house, clinging to each other, making out like this, you realize that you could pass for a couple of lovebirds spending an intimate afternoon together; and this turns on much more than you would like to admit. Even if you've just orgasmed, you're ready to resume.
"I... I made her happy..."
Maddison gets closer to your ear: -I'm ready.- she whispers. She moves again, this time lifting up and readjusting in an unequivocal manner. Your member goes erect instantly, and then she drops down, devouring it inside her thighs. You feel your penis being enclasped between tight, slippery, fleshy walls, a sensation both familiar and extraneous, a wonderful ecstasy of all your senses. Aunt Maddison completely eases along your body, starting to pump up and down, slowly, savourly, relegating you to the missionary position.
The excitement that you're feeling now, it's somehow different from the one with your family. It takes you a moment to understand why.
You two are not just having sex, like with Mom and Kim and Tina on the couch; no, you two are making love.

-Ahh...- She moans, water crisping around her at every jab.
-How does it feel, honey? Aww! It surely feels g-good from this side...-.
You nod, your mouth reeling to get some air.
-It-It feels good too, Aunt!- You confirm.
-Mmm... I'm so happy...- She presses herself tighter onto your body, creating for real with you the beast with two backs. Her boobs are squashed against your chest, sliding up and down like smooth sponges. She nests her head over your shoulder, sensually nibbling your ear. You suddenly feel an unexpected sting of pain on the eardrum, maybe due to the pressure surge; but it lasts only one second, and the moment later you're catapulted back into this delirium of pleasure. Strangely, you now wonder if she has ever done so with her husband; your uncle, that is. No, you answer to yourself, she's just for you.
-I'm so... so proud of you, Tom.- She moans on your auricle: -You've been repressing this for so long... just because you wanted to protect me... you were scared of me...-.
Your raving mind struggles to metabolize her words. Yes, yes you've wanted to do this for a long time, because you thought, nay, you were sure that she wouldn't have understood; but now, even if she's not herself anymore, now she does. Now she shares this with you. Now you can finally love her as much as you've always wanted.
-Y-Yes...-.
-And you're doing so well, so well Tom... Ahh... Now I see why, why my sister loves you so much...-.
Her sister... your mother... yes, yes she's right, she loves you too...
-Tell auntie the truth... tell me where is Emily... you know where she is, right?-.
Yes, Emily, Emily is...
"No.".
You open your eyes wide, as if you've just woken up from a beautiful dream via cold shower; chilly shivers are tingling on your back, but your focus is sabotaged by a deeper thrust that makes your pupils roll back in their sockets.
-I don't know...- You find the strength to say. You feel your aunt's breath pause for some seconds.
-Are you sure, honey? She is... she is in great danger, I'm afraid... I just want her to be safe... with me... with us...-.
-I... I swear I... don't know...- You groan back. She pulls back her visage, looking at you straight in the eyes; you're toiling to keep yours open, and you know, you sense that you wouldn't be able to lie to her once again. But you won't have to.
-Ok...- She nods, a reassuring smile on her face.
-I'm sorry if I doubted you...-.
She then kisses you, infiltrating her tongue between your teeth and inciting you to do the same. The most luscious kiss you could dream of, and it makes you forget everything else for a second. When she detaches, she gets up, your cock slipping out with a little splash, and you fear that she has somehow seen through you. Instead, staring at you with fiery, **** eyes, she turns around, flaunting at you her ass, the one you were taking glimpses of from the beginning, the one which is now nude and swaying before you.
-Pounce me from behind, Tom. Fuck me hard, honey, fuck hard your dear auntie.-.
Even in your alarmed state, those words, that tone, you can't resist them. You stand up, you allineate your member with her pussy, and then you push in, finding no resistance as its inner walls are now perfectly fitting your size.

-Aaahh!!!- Her cry is louder than any of the previous ones, and her face is of an intensity that borders with sorrow. You're the one leading now, and it's like a bestial instinct has awoken in you, the primordial imperative of breeding with a female in heat. It doesn't matter if it's the vagina most related to your mother's one; nay, actually, this makes everything even more feral.

-Don't hold back Tom! My little auntie's boy!!!-.
What comes later is a wild sequence of sexual acts which you go through without recording them in your brain, just following the call of nature. At a certain point, you find yourself on an air mattress, with Maddison letting herself be impaled by you.

She can't be my aunt, you think.
Fuck it, she's so hot moaning like that.
-Ugh... oh! Oh, oh, ohh!!! Gimme that, gimme everything you have Tom!!!-.

She keeps her buttcheeks spread, allowing you to better penetrate her. Jesus Christ, this is where Emily has come from, this is the hole that has given birth to your cousin, to your sexy, hottie cousin, the girl you'd die to have here too, alongside her mother. God. She would never forgive you if she found it out.
Maddison's moans are converging into high pinched cries. She lies on her hip, making you turn in consequence, and now it's you again the one hard pounding.
-I'm cumming!!!- She screams: -I'm cumming I'm cu-UU-OOOOOOOHHHH!!!-.

You stop your thrusts, marveling in awe at the woman in front of you shaking in wild spasms, while you feel a sticky fluid pouring on your erection. She dismantles from you, and as your groins detach a transparent liquid leak out from her pussy.
"I just... I just make her squirt...".
She turns to you, a satisfied smile on her panting face.
-Tom... it was... amazing! Ohh I love you, my boy!- She kisses you again, and this time you're ready to reciprocate. You lose yourself in her dreamy eyes: -I love you too.- you reply as if it was the most normal thing in the world, later returning the kiss.
She slily lowers her gaze: -Mmm, but you're still hard. You're truly an endurer...-.
You blush.
-Well, let me reciprocate the favor...- She moves toward your crotch, slipping between your legs and taking your moistened dick with one hand. You smile in anticipation, right the second before she closes her eyes and sinks her opened mouth onto it, blowing you for the second time in half an hour.

CHOMP SMUNK CHOMP
You don't know whether it's your excited body or her entranced state, but it feels even better than before, as she uses also suckings and smacks to her advantage. She doesn't want you to last any longer, and such intention is sealed when she looks up at you with a pair of excruciating, demanding eyes.
Silly you. You think you've been good to last up to now, but it was her who had let you.

-I'm, I'm so close!- You wail. However, a particular memory, coming from not long ago, is haunting you. One thing has been even better than her mouth.
-Your... your tits! Let me... p-please!-.
She doesn't need anything else. In a quick motion, she's positioned under you, squinting her breasts with her digits. You put yourself on your knees and, once again but for the last time, you throw your cock in.

You don't have time to elaborate on the sensation. When you see your aunt's dangling mouth and her eyelids closed, you can't hold it back anymore, and you finally blow your second and last climax onto her burning skin.

You stay still, heavily breathing, while the clarity of the post-orgasm begins to resurface in your mind. Below you, your aunt giggles, admiring the white droplets of sperm splattered across her bosom. Your penis, still semi-erected, bounces on it a pair of times, before you eventually crawl back to gain some breath.

Minutes of silence pass, punctuated by the sound of your mingled pants. If you look back right now, you almost doubt this has really happened. But it did, and you still can't imagine its consequences.
What now?
