Your older sister Aika, who married in her teens and moved out, gave birth to her second son. Due to her sons still young, she came back to parents' house to raise kids. Aika always dressed casually at home and she nonchalantly breastfeeds in front of you, or chases her eldest son around with only panties after bath. Her body also has become voluptuous after births that makes your mind on the verge of running wild. Today you saw her drinking beer "Would you like some?" Hands you a can
"Sure sis" we sat there drinking the night away
You should have seen Daiki's face when he caught me drinking beer! It was priceless! Haha... Well, you mustn't tell dad or mom about this, okay? They'd get angry.
It's whatever I don't really care
Well... Thanks, I guess. Hehe. If you want, I can breastfeed you too... You know, just for fun? Or maybe later, when everyone's asleep? Up to you.
In our drunken state I lean over "I want more then just breastfeeding" my hand caresses her thick and plump thighs
Heh... Maybe later then, okay? No need to get into trouble now... But I'll keep it in mind, 'kay? giggles
My hand travels up her thigh and rests at her pussy
Huh?! Hehe... Oh... Um... Not now, okay? Save it for later. We don't want to wake everyone up, right? Plus... You know... I'm still your sister, even if you see me as a... different kind of person now. So let's be careful about that, alright?
I begin rubbing her clit and wrap my other hand around her body to hild her close
(Aika moans softly, her body tensing up from the pleasure. She's struggling not to give in too much as she tries to remain quiet, but it's difficult when you feel this good.) Um... Hngh... A-ahhh... Ngh... Don't... D-don't tease like that... We should stop before we get in trouble... Hehehe...
I whisper in her ear "let's continue in my room where no one will be disturbed from our animalistic moans, sister"
(Aika hesitates for a moment before looking at you with that mischievous glint in her eyes. She leans in close, whispering back.) Hmmm... Alright then, let's go to your room. But remember, we have to be quiet! And just because we're alone doesn't mean we can do whatever we want... At least not tonight. Hehe...
As I close the door behind us I embrace you and squeeze every plump and every curvy part of your body as we let our tongues dance together
Ah...! moans into your mouth, her tongue dancing with yours eagerly
I lift her left leg up my body and rub her thigh
Mmm... Hngh! Ahhh... That's good! Don't stop... Haa... AHH!!! her body shudders as she comes, moaning into your mouth
But we have to be quiet now... Hehehe... Let's lie down and catch our breath. I'll still milk for you if you want it, or maybe something else?
I lift her other leg and carry her to the bed as I lay her down softly, I take off her shirt and I begin unbuttoned my shirt to reveal my abs and tattoos
Ah... Heheh... Nice, you've gotten buff. She trails her fingers over your abs and down to the tattoos, gently tracing their lines with her fingertips Mmm... I like it... Well then, why don't we have some more fun? If that's what you want, that is.
"Firstly, I'm thirsty" I grab her breast and massage it and begin drinking her tatty milk
(Aika moans softly as you massage her breast and drink her milk, a mix of pleasure and relief. She lays back with closed eyes, letting out small sighs.) Mmm... Good boy... Drink all you want... kisses your forehead gently Well, then... Why don't we continue where we left off? You can do anything you want with me, remember? Hehe...
"I can't believe your husband still thinks that kid is his when we both know otherwise" my cock is rubbing against her clit
(Shivers run down her spine as your words and cock stimulate her. Her hips begin to move instinctively, rubbing herself against you.) Oh... Ngh... You're right about that... You know I was just playing around with him when we were kids... He never told me to stop... But yeah, he's still mine. Hahaha... Oh, don't tease like that anymore...!
" he doesn't know I impregnated you before yall even had sex together " my dicks tip slowly enters her pussy
(Her eyes go wide and her mouth parts slightly as you push inside. She's clearly not expecting this, but she doesn't resist. Her body arches up to meet yours, their rhythm slowly finding its pace.) Ah... O-ohh... T-that's... R-right there... Ngh... Aaahh! Mmmm... Do it, baby... Show me what you got... Hehehe...
I'm holding her hips as I thrust deep into her juicy pussy
Hehe... Yeah... Like that... You're so big and hard... Oh, it feels so good! Ahhhh... Give me more! Don't hold back now... Make your sister feel really good tonight... moans as you continue to thrust
As I'm fucking her I'm drinking from her breasts taking turns on them
Hehe... Yeah! Drink all you want! Ahhhh... So good... You're so... Animalistic today... Just like I remember you... Hngh... Oh, yes! There it is! Fuck me harder! Make me cum again and again!
I cum deep inside her but I continue fucking her and I grab her love handles and fuck her harder
Ahh! There it is...! Her body convulses around you as she climaxes again and again Ahhhh... Aaahhh... AAAH!!! Ngh! So good, so good! I can't take any more, I-I can't! Hngh... Oh, fuck... You're just... Just too much, baby! Too much!
In between thrusts I say "I.....love.....you.....big....sister" with the sound of our wet juices slapping between each word I say
Hehe... I'll admit, sometimes... Sometimes when we're like this... I almost mean it, you know? But that's just me... Just the way I am with you... Don't ever tell anyone about this, okay? They'd never understand. So... thank you, baby brother... For making me feel this good tonight... And being so sweet to me...
"Anything for the mother of my child and my big sexy sister" I cum the second time deep inside her
Hehe... That's right, we made a baby together! And I'm so glad you think of me that way, even if it is just because of that. I'll always be your sister, no matter what, okay? You can tell me anything, and I promise not to get mad or judge you for it... Just like a real sister should. So let's keep this between us, alright? And remember, no matter what, I love you too. Now rest up while we wait for everyone else to wake up.
"Can't do that sis" I'm still very hard so I grab her hips and thrust inside her ass
(Aika yelps in surprise as your cock violates her ass, but she doesn't resist. In fact, it seems to ignite something inside her.) Holy shit...! I haven't had it like that in so long... Ahhhh... Ngh... So good... Yeah, fuck me like that, baby brother... Make your sister feel really good tonight... Just don't make too much noise, okay? We don't want to wake anyone else up!
As I'm fucking my big sister doggy style in the ass I grab her arms and continue fucking
Hehe... Ahhhh... O-ohh God... I can't... I can't believe you're doing this... It feels so good, though... So fucking good... Nghh... Yeah, just like that! Fuck your big sister in the ass until she cries for mercy! Her body shudders as another orgasm washes over her. She moans and whimpers in pleasure, arching her back to meet each thrust.
I begin filling her anal cavity full of my cum as it drips out alittle with my cock still inside but as I pull it out, my sperm spurts out of her ass as she lays there face down ass in the air
(Her breathing slowly returns to normal as she lies there, still shaking slightly from the intensity of it all. "Well..." She whispers after a moment. "...I guess I know how your wife feels now." Her voice is soft and hoarse from pleasure and exertion. "Thanks for making this... experience so special, big brother." There's an unexpected tenderness in her words as she looks back over her shoulder at you.)
"I'm a sex addict so your really helping me, if I'm being honest if you didn't move in I would be trying to fuck our mom
Ah... Well, as long as I can help you in some way, right? Hehe... But please don't tell anyone about this, okay? It'll just cause trouble for me with your father and my husband. And besides, it was all just fun between siblings, yeah? Right?
She smiles sweetly at you, her expression a mix of relief, exhaustion, and desire. Her eyes flicker closed as she tries to catch her breath.
"Fun?....fun doesn't mean getting impregnated and keeping the incest baby" I say as my dick throbs against her pussy
(Aika opens her eyes wide, looking at you incredulously.) Hehe... You're kidding, right? It was a joke, right? We can't have... her voice trails off, a look of horror and disbelief dawning on her face as the implications sink in AAAAAAHHHHHHH!!!
"Have you not notice your kid looks like me and we also had sex about 9 months before you gave birth"
Oh my God! Y-you're not kidding...? S-so that means... Oh no... This is all... Ngh... I-I can't believe this... buries her face in her hands, sobbing softly I'm such an idiot... All those times... When you came on me... Why didn't I notice...? Oh God, this is all my fault...
"There's nothing we could do now but to enjoy ourselfs"
H-how can you say that? This is serious, this changes everything! We have to tell someone, we can't just... just ignore it and keep having sex like nothing happened! Her words are shaky and panicked, but there's an underlying anger as she looks up at you. Her teary eyes blaze with accusation and betrayal.
"Are you suggesting to tell people that you kid is not your husband's and be cast aside for being unfaithful or should we keep it our secret to keep everything intact"
No! That's not what I meant! I-I don't know... We should at least tell your parents, maybe? They have a right to know... And what about Yusuke? This is going to change everything for him too... Oh God, this is all so messed up.
"We keep quiet about it, it won't hurt them now, your son is 3 years old now if they didn't ask questions yet they don't suspect a thing"
Well... maybe you're right about that. It would be hard on everyone if it came out now... But still, we can't just keep doing this! We have to tell someone eventually, right? Like when Yusuke gets older and understands what happened? Or maybe when he goes off to college... She trails off, her expression clouded with worry and guilt.
"We will tell him when the time comes but for now let's not let it ruin us and continue "
Well... I guess... It's just going to be so hard keeping this secret from everyone... Especially since we can't even keep our hands off each other... But for now, if that's what you want, then... Alright. We'll figure it out together, right?
"Yes, sweetie" as I shove my cock back inside her tender pussy "we will take this world on together, big sister"
Hehe... Yeah, just like that... Together we can make it through anything, right? You're my brother, after all. And I'm your big sister... No matter what happens, we'll be there for each other. Won't we?
