Lemon in the Same Household
Later at the Uzumaki House
Naruto enters and heads over to the living room and lays down on the couch while thinking that it's a been a short day, But he stops thinking about it as he wonders if Samui is home or not, He gets up and heads up stairs and walks towards Samui's room.
It didn't take Naruto long to be in front of Samui's door and and since it's close, Naruto isn't sure if his sister is in it or not, So he Knocks on it and says "Samui? Are you here? If so let me know like that I ca-" before Naruto finished, Samui opens up her door while rubbing her eyes because she was taking a nap for most likely a hour or two as Naruto says "oh You were sleeping sorry about that Samu-" and once again before he could finished.
Samui grabs Naruto and drags him in her room and closing the door, And before Naruto knows it, He's on Samui's bed with Samui herself next to him as she holding him and has his head between her Double J size breasts as she feeling very happy about this with Naruto blushing badly.
Naruto doesn't understand why Samui is doing this but to found out he has to ask her, "umm Samui why are you doing this?" said Naruto as he blushing more as Samui says "because I missing having you between my breasts as well snuggling with them but you stop doing that with me when you were 9. Why Naruto-kun?" said Samui as Naruto tries to move away from her breasts "because my friends told me that it was weird for siblings to do it." said Naruto as he failed to move away.
"And you shouldn't have listen to them Naruto-kun" said Samui and she keeps talking "because I want you to be the only man to do it" when she stops talking and finally something happens.
Samui Kisses Naruto deeply which surprised him greatly, Samui Stops kissing him but however Naruto kisses back while he has his right hand into her heart shaped ass and his left hand gropes Samui's left breasts.
And the kiss itself was very deep and possession while Samui is blushing badly as she looking at Naruto and both of they eyes are looking at each other.
Lemon Starts
Naruto stops the kiss as he grabs Samui's shirt and takes it off follow by her skirt leaving only Samui's black lingerie see through bra and panties with the Uzumaki swirl on them.
"N-Naruto-kun, w-what a-are you going to do me?" said Samui as she blushing badly as Naruto doesn't know what he should do "I don't know! I mean we are brother and sister! We shouldn't do going this" said Naruto as Samui say to make it more easy for him "go ahead Naruto-kun cause I wanted my first to be with you because I love you so much" said Samui and just like that Naruto made his decision.
By grabbing Samui's bra and takes it off and Samui's breasts bounce lovely with her nibbles harden, Then Naruto starts sucking on Samui's right breasts while groping her left.
And Samui herself monaing loudly while blushing even more while she has her hand on Naruto's hair, Then Naruto starts sucking on Samui's left nipple as she is moaning louder than before.
After doing that for a bit, Samui is off of her bed and on her knees while Naruto is sitting on the bed and Samui is slowing removing Naruto's orange pants and she does and leaving only his boxers which are green then Samui notice a bulge that had form under the boxers.
Samui gets closer to it while slowly removing Naruto's boxer and Naruto sits there and watching and waiting as Samui fully removes Naruto's boxer with long and huge rod hits her on the face by surprised.
What Samui sees as she's in surprised in hell that the thing that hits her face is Naruto's 10 inch cock and how thick it is, And Samui can't help but think that Naruto her little brother has a big cock thats way bigger than the one that she saw in a book.
"N Naruto-kun, Y-your c-cock i-it's huge" said Samui as she blushing like crazy as Naruto say "you think so?" as his cock gets harder then it was before, And Samui snaps out of it and starts stroking it lightly and Naruto moans and groans lightly then Samui out of nowhere began licking Naruto's cock starting with the tip then makes her way to the bottom then giving it kisses.
With Samui doing that, Naruto moans louder as he is enjoying it greatly and Samui stops at the tip part of Naruto's cock as she gives it one more kiss before she takes it into her mouth.
And so Samui starts sucking Naruto's cock and was able to take less than half of it inside of her mouth and Naruto says "damn you're very good Samui-chan!" as he feels his cock inside of Samui's mouth as he founds it very nice and warm as Samui herself is bobbing her head at a fast rate as she thinking how amazing Naruto's cock tasted.
Then Samui stops sucking Naruto's a cock which that confused Naruto then he sees Samui lift up her breasts and wraps the rest of Naruto's cock as she resumes sucking Naruto's cock while starts her rubbing her breasts onto Naruto's cock as Naruto is getting overwhelmed by this combo.
Having his cock suck by Samui who is his sister as well as having her breasts rubbing onto his cock, and Both of them are loving this more by the sec as the whole room is getting full by the scent of sweat, love and lust as more and more of it are being made more by them.
After 13 minutes of enduring it, Naruto feels something coming from his cock after being suck and rub by Samui, That means he can't hold it any longer as he says "Samui-chan I can't hold it anymore! And your tits are so soft!" who about to cum into Samui's mouth and Samui knows what he means and so she starts sucking Naruto's cock even faster than she could.
With a full minute with Samui bobbing her head and when she has all of Naruto's cock into her mouth and down in her throat, Naruto on that very moment unleash his load of cum into Samui's mouth and down into her throat.
Upon feeling Naruto's load into her mouth, Samui lets go of her breasts and holds onto Naruto's upper legs as she tries drink Naruto's cum but she thinks that it's too much for her take.
