In this alternate universe, Minato and Kushina live after the Nine tails attack. Minato remained the fourth hokage and their son Naruto and you are best friends.

You and Naruto's team had returned from a mission to drive out some bandits threatening a small village.

Upon arrival in Konoha, Naruto had invited you over to his place for dinner. You were hungry and didn't want to go out or cook for yourself so why not?

Within 20 minutes you both arrived at Naruto's home. As you entered you saw Naruto's mom, Kushina, cooking up a storm.

Kushina: Welcome home Naruto! Oh hi y/n.

Y/n: Hello Mrs. Namikaze!

Kushina: No need to be so polite ya know? Just Kushina is fine.

Y/n: Yes ma'am.

Kushina: Y/n what happen to your shoulder?

Y/n: Its nothing, just a scratch from the bandits. Got carried away trying to impress Sakura. Haha.

Kushina: Ain't Sakura a medical ninja? Why didn't she tend to you?

Naruto: Y/n and I are tough guys we don't need anyone to tend to us!

Kushina stomps on over and bashes your heads together.

**Clunk!**

Y/n and Naruto: Ow!

Kushina: You two have to be smarter than that! What if it was infected!

Naruto mutters some words before Kushina pointed at the couch.

Kushina: Go sit down and wait for me!

Without any disagreement you both went and sat at the couch.

Shortly after she had patched Naruto up.

Naruto: Alrighty then I'm gonna hit the shower!

Y/n: You go ahead I'll wait for your mom to patch me up.

Kushina had clean your wound and bandaged you up. As she finished up she felt how firm your chest was.

Kushina: For someone your age you're very firm.

Y/n: Thanks.

Kushina : So... sexy...

Y/n: Huh? What are you...?

Kushina places her finger on your lip. Shushing you. Her eyes met up with yours. She lightly whispers:

"It's been a while since Minato made love to me... your quite the stud too y/n..."

Y/n: I don't think we should do this...

Kushina: Naruto will be a while... so...

Kushina pulled down your pants revealing your limp cock. She takes it into to her hand and strokes you. Her lips kissed the tip while she fondled your balls.

You laid back as Kushina played with your manhood. Your balls tingly. Your cock aching and twitching. Some pre cum leaked from your tip.

Kushina took your cock into her warm mouth. The sensation overwhelms you. Your friends hot mom is sucking your dick.

Her hand planted at your base as she sucked you faster. Her tongue still working the underside of your head. The pure ecstasy takes you putting you on the edge.

Y/n: Kushina I'm coming..

Kushina sucked your cock harder. Slurping your cock as she pulled up. Her fingers teasing your balls. Her moans aroused you urging you to explode.

You grunted as you thrusted up shooting deep in her mouth. Kushina sucked you for a bit before she pulled off.

Kushina: That's your taste big boy... if you want more come into my room tonight after dinner... my window will be open.

She winked at you and gave you a quick peck on your lips.

Later...

After dinner you left and made your way to Kushina's window. You went in to find Kushina laying on her bed completely exposed to you.

Kushina: Round two y/n? Hehe.

She giggled flirtatiously. Her legs opened wide showing her wet pussy. Her fingers gently rubbing along her slit.

Kushina: I'm all ready for you y/n. Now take me...

You strip off your clothes and climbed over Kushina. Your thick cock inches away from her pussy. She gazed into your sexy eyes as she wrapped her arms around your shoulders. Her legs raised to your hips.

You guide yourself into her pussy and her tight walls grip you instantly. Her cries were so ecstatic making you plunge deeper. She cried out as you thrusted inside her.

As you pumped her pussy faster she held you closer to her warm body. Your hips thrusting into her pussy.

Kushina pulled your head down to hers and kissed you passionately. Her moans filled you with ecstasy. Her hand firmly groped your ass.

You pulled away as you reached your limit. Pumping her harder. She gazed into your eyes with her lustful look.

Y/n: I'm coming Kushina!

Kushina: Fill me up y/n! Ah!

She let out a sexy cry as you thrusted harder shooting your cum deep inside her. You grunt with each thrust shooting every drop inside. Before you could take a breath Kushina rolled you both over.

Her eyes filled with lust as she rode on top of you. You swear your seeing things cause her hair seems to have come to life. Her hair flowed freely in the air. Her pussy gripped tightly and somehow got strangely warmer.

She began to grind her pussy rubbing your cock from all angles.

You held her hips as she rode on your cock. She moaned gently cupping her breast and playing with her clit.

Kushina rode you even faster crashing her pussy down on your balls. She grunted with each pump. Your grip on her hips tightened urging you to thrust.

Kushina: I'm coming y/n! Make me cum!

You responded by thrusting faster. She held her body up as you pumped your load ferociously inside her womb.

You both took a quick breath before resuming.

Kushina braces herself up by the window spreading her legs for you. Her dripping pussy aching for your cock. You walked behind her kissing her neck. Your hands cupped her round ass working your way up the hips to her breasts.

You pressed yourself onto her body with your cock throbbing by her pussy. Her breasts pushed against the window fogging them up from her heat. She took your cock and slid you into her pussy.

As your head got in you thrusted the rest of your cock inside. Your pounding made her yelp in pleasure. Her pussy grips you tightly. She holds onto the drapes as her body trembles from your thrusting.

You were on edge ready to shoot everything you had left.

Y/n: I'm gonna blow Kushina!

Kushina pushes you away and got down to her knees taking you into her mouth. You continue thrusting into her mouth gagging her with each pump. You held her head firmly and shot everything you had left inside her mouth. Your cum drips out of her mouth while your cock throbs inside. She pulls out your cock and licks up the remaining drops on you.

Kushina: So tasty... but it's time for you to go y/n...

You sense a chakra spike nearby instantly. Your mind shouts out, "Shit Lord Hokage!"

You quickly gather your clothes and booked out the window. You took one glance back and saw Kushina waving good bye to you.

Since this night every stop you made to Naruto's place you always had a quickie with Kushina. Minato never caught wind of this nor did Naruto. He was a heavy sleeper and Minato always worked late.

Months went by and you heard from Naruto that he was gonna have a baby sibling soon. You were shocked from this and knew it was a matter of time before they find out that it's not the Fourth Hokage's kid...

Or pray that the kid has Kushina's hair color eh?
