For the longest time, Hinata had always believed Naruto's parents had the perfect relationship. They loved each other. That was as clear as day. They could barely keep their hands off one another when together and spent all their time as a pair when Minato wasn't acting as Hokage in the tower. Not only that, even though they were both in their forties, they looked to be in their late twenties. It was an encouraging sight to see, and Hinata had always hoped she and Naruto would be the same when married.
After marriage, though, and living in the Namikaze household, Hinata had learned a very important detail that she'd never noticed or perhaps hadn't wanted to. Kushina, her mother-in-law, was a slut. Not just as in she enjoyed sex, but also in the fact she let random strangers fuck her. Ninjas, civilians, it didn't matter. Men Hinata had never seen in her life visiting the house in secret while Minato was away to have fun with his wife.
It was terrible, and Hinata, even after watching in secret for the last few months, couldn't bring herself to tell Naruto what his mother was doing behind his father's back. She knew how much it would hurt him to know what was happening... and at the same time, Hinata didn't want to give up her secret for another reason.
She enjoyed watching Kushina.
It wasn't a new thing or specific to the redhead. But Hinata had always gotten turned on watching people have sex, cheating or otherwise. Something about the act lit a fire in her that she could never pull her eyes away from whenever she discovered it. Her friends, her friends parents, neighbors, random strangers. Something about it just turned Hinata on like nothing else did... Well, except for Naruto.
That was why, instead of taking a nap like she'd told her husband, Hinata was lying awake in bed. Byakugan was active, her hand underneath her dress as she masturbated, watching a few rooms away as Kushina met with one of her lovers in the laundry room. The man a pale blonde, unlike Minato, but with green eyes and heavily tanned skin. He was someone Hinata had heard Kushina call Scar. Not exactly creative, but he was a regular over the last few months as far as she knew.
Biting her lip, Hinata focused her chakra into her ears to listen to what Kushina and Scar were saying. The sound of choking was the first sound appearing in Hinata's ears, Kushina already on her knees, mouth sucking on Scar's cock as the man leaned against the washer, a pleased smile on his face.
"That's it, Kami. I knew you were my favorite housewife for a reason. How many cocks did you have to blow to get this good, I wonder?" Scar smirked.
Removing her lips from the stiff cock in her mouth, Kushina smiled wickedly while unbuttoning her shirt, letting it fall to the floor. "Didn't you teach me this? Minato certainly hasn't, and I've spent much more time on my knees for you than my husband."
Lies. Hinata thought and almost wished she could tell Scar that to see what the man would do as she watched Kushina deceive her lover. Lowering her head and bobbing down on the cock of the ever-gullible Scar, exactly as Kushina had done with several men in the last few months. Funny enough, none seemed to disbelieve the lies, or instead, maybe they just chose to ignore what spewed out of Kushina's mouth during sex.
"That's true... Fuck I'm getting close. You better get ready bitch." Scar groaned, grabbing Kushina's hair and pulling her down on his cock. Not looking surprised, Kushina didn't struggle, going down further until she was at the base of Scar's cock. Staying there as she formed a seal with her lips.
Hinata, able to see it all, watched as Scar's balls twitched and rope after rope of white sticky cum flowed down Kushina's throat. The milf taking in everything with ease despite the virile amount of cum that almost rivaled Naruto. Not a feat Hinata had ever thought she'd witness, until she had, over a dozen times with the men Kushina kept finding. All of them always having large cocks that soon found their way into Kushina's body, no matter the situation.
"Mmm... Delicious as always." Kushina hummed after she slipped her mouth off Scar's cock, licking her lips. "Now, why don't we finish what we started? I want you to make me cum at least three times, only without interruptions like last night."
Last night! Eyes wide, Hinata picked up her speed as shd fingerfucked herself, a wave of heat flooding her body at the news she heard. Last night she hadn't even noticed one of Kushina's lovers arriving. She hadn't paid much attention, with Naruto ravaging her, keeping all her focus. That wasn't important, though. What was, was that Minato was home last night. Which meant Kushina had met up with her lover while her husband was home. Hinata had never seen the woman do that before. Why was she now?
"That was unfortunate... Deal. Maybe this time you'll even let me cum inside you." Scar chuckled, giving a swat to Kushina's large bubble butt, the flesh jiggling slightly as the redhead smirked and placed her palms against the wall. Her back arched as she spread her legs.
"Not so fast, tough guy. My husband is the only one allowed to do that."
"As if that makes a difference."
Seeing Scar bury his cock into Kushina with a single thrust, her mother-in-law's face changing into one of utmost pleasure, Hinata couldn't help but agree with the pale blonde. It was a funny rule, and one a little strange that Kushina had held onto with how much she cheated on Minato. It wasn't as if she couldn't use a seal to prevent pregnancy, either. But no matter, she would probably never know unless she asked... So she was probably never going to find out the answer.
Feeling her own orgasm approaching, Hinata started bucking her hips a little more wildly, trying to reach that high when she froze, her eyes locating Naruto as he entered her vision in the hallway coming her way. Acting quickly, Hinata fixed her dress and threw on the covers to hide her sweaty appearance. A little bit of guilt filled her at how sneaky she was trying to be, which in all honestly, she knew she didn't have to be. There was nothing wrong with her masturbating. It was what she was masturbating to, though, that kept filling her with guilt whenever Naruto almost caught her in the act like today.
"Naruto!"
"Ah, you're up Hinata. Well, I'm glad one of us got some rest. Can you believe Mom and Dad? I could hear them from the living room going at it. I swear, they're worse than us, and we just got married." Naruto groaned, flopping on the bed next to Hinata.
"Ah, I didn't know." Hinata lied, blushing red at her husband's close proximity, a habit she'd yet to break. Still, a part of her heart broke at Naruto's words, the man living his life in such an illusion, not knowing the person downstairs with his mother wasn't Minato. It almost made her want to confess what was going on right then and there.
"Yeah, who knows how long they're going to be."
At those words, Hinata glanced down toward the laundry room and witnessed Kushina in the midst of an orgasm, the redhead's body shaking while Scar pounded her from behind, the strings of semen on Kushina's back making it clear the man had already shot another load. Though Hinata wasn't surprised to see he kept his word, all the men of Kushina's obeyed her to some degree unless she didn't want them to obey.
"T-They'll probably be a while. Why don't we go out for dinner instead of cooking here?" Hinata asked, knowing she wouldn't be able to get off now, so leaving and resisting the urge to watch was the better option.
"Great, let's go get Ramen!"

"Man, Mom's taking forever. It's been half an hour already. Her food's going to get cold." Naruto groaned, clearly eying Kushina's dish, his own plate of barbecue half finished already.
"She's probably talking with Mikoto or something," Hinata replied, only half paying attention to her husband. The rest of her focus was on Kushina, who'd left them in the middle of their dinner and was now in the restaurant's bathroom. Blue, a man like his name with radiant blue eyes, balls deep in Naruto's mother. He was another regular, and Kushina, after entering the bathroom, as if knowing the man was there, had hiked up her dress and told him to fuck her.
It was rather annoying for Hinata. Not because she didn't enjoy the viewing, far from it. But rather because she couldn't masturbate and find relief from the heat coiling inside her.
"Fuck I can tell, Scar loosened you up for me." Blue hissed, his hips slapping against Kushina's thighs with a wet slap as they met each other's pacing. "Does that idiot brother of mine still believe he's your only lover? I can't believe he was bragging about sleeping with the Hokage's wife again as if I wasn't doing it too."
"T-That's not exactly fair~!" Kushina gasped, her hair already clinging to her from the sweat covering her body. Her black dress stuck to her skin like a glove showing off her voluptuous figure. "You did introduce us, remember?"
"Oh, I remember." Blue grinned, thrusting a little deeper, pushing Kushina against the stall wall as he pressed a short but heated kiss against her lips. "It was the morning of your anniversary, if I recall correctly. I'd shot my entire load into your mouth as a gift, then set you up with my brother as a blind date. The first married woman he'd ever had sex with."
"What do you mean first?" Kushina moaned, clenching tightly around Blue's cock, hitting inside her body. "There better not be another woman stealing away my fun."
"Ha, I suppose you're right. There's no way either of us could see someone else when such a sexy housewife is willing to be our fucktoy whenever we desire."
I think it's the other way around. Hinata groaned inside, keeping her eyes on the affair going on right up until Blue pulled out and shot his cum all over Kushina's ass. From there, it seemed they were done. Kushina simply pulled up her panties over the cum on her body and straightened her dress as far as a clean-up went before she kissed her lover goodbye.
A few minutes later, Kushina sat down, and Hinata could almost swear she could hear the squelch as she did so. Her eyes could see it all clearly as the cum soaked into the fabric of Kushina's panties and dress. The dampness of it was only hidden because of the black color of the fabric and because some of it was drying against the redhead's skin.
It was disgusting, or at least should have been, not that Hinata really believed that thought herself, her own panties soaked after what she'd watched. The almost daily voyeur sessions of hers had become a favorite pastime she was growing more and more to enjoy. It also helped that it did wonders for her and Naruto's sex life. Hinata usually turned on that, as Naruto put it, 'at night she turned into a frisky wildcat' in the bedroom.
"Sorry about that. I ran into an old friend." Kushina beamed, the sight making Hinata smile right back despite what she knew.
"It's fine."

"No, you can't!"
Hearing Kushina's voice yell from upstairs as she stepped through the door to the house. Hinata immediately flashed on her byakugan to see what was happening and almost gasped as she saw Kushina in bed with Zero. He was an old student of Kushina's. At least, that's what Hinata had gathered from overheard conversations. That wasn't what made her gasp, though. What made her gasp was that Zero was currently releasing his load inside Kushina's pussy.
Kushina was on her hands and knees, breasts swaying in the air as the man continued to fuck the redhead, not letting up at all, even as he shot his load into her, breaking Kushina's one rule. A rule every single man had followed until today.
"I can't what, sensei?" Zero laughed, cock still hard as he continued to fuck Kushina's tight body. "Isn't this what you wanted? Why else would you refuse to use a contraceptive seal yet tell me not to cum inside you? Haven't you been waiting for this exact moment? For one of your lovers to knock you up? Well, I did. In the bed you sleep with your husband with no less!"
"T-That's not true~!" Kushina moaned, her eyes half-lidded at this point, looking like a total mess.
"Sure it is." Zero smirked and laughed again. "To think I was the first to even try is a great ego boost. I've wanted to do it since you were prancing around in those skin-tight pants of yours when trying to train us all those years ago. Half the time, I'd have to leave and let off some steam as I imagined ripping them off this sexy ass of yours and shoving my cock inside you."
"Fuck!" Kushina shrieked, her body trembling as she reached her orgasm, her arms giving out as she fell against the sheets. Zero continued to fuck her into the bed as the wet slaps echoed in the room. Hinata down the stairs, now sitting in a chair furiously masturbating as she watched.
A part of her almost wanted to run upstairs and stop what was happening, just in case this wasn't what Kushina wanted. After all, cheating was one thing, even if the word seemed a little tame compared to Kushina's scale of doing things. However, getting pregnant, Hinata knew that was going too far... Yet she couldn't bring herself to go up and stop it, the small smile on her mother-in-law's face as she got fucked over and over by Zero, making her understand Kushina was more than okay with what the man was doing.
"That's it, damn sensei." Zero hissed. "Here's load number two. I hope you have an excuse ready for your husband later."
Groaning herself, Hinata closed her eyes for a second as she hit her sweet spot, cumming all over her fingers on the kitchen chair. Kushina's womb locked in her vision as she watched Zero fulfill his words. Stuffing his thick cum into Kushina's body and most definitely getting the redhead pregnant, overfilling her pussy as it began to leak out the sides of Kushina's stuffed hole and down her thighs.
Catching her breath, Kushina pushed her hair back behind her ear and gave Zero a sexy-looking pout. "That was mean, you know that? Now I'm going to get all fat and have to quit having sex later if you really knocked me up... Happy now?"
"Very. I'm sure Naruto will be happy with a new sibling... Now... Up for round three?"
XXXX
"Everyone, guess what?" Kushina smiled, placing a hand on her stomach. "I'm pregnant!"
"What!" Naruto's mouth dropped open in shock, then he groaned, looking bemused. "I should have known this would happen. Really dad? You guys beat Hinata and me."
"Sorry, son." Minato chuckled, rubbing the back of his hair in a way that reminded Hinata of Naruto. "It wasn't exactly planned, more of a spur-of-the-moment thing."
"C-Contratulations Kushina." Hinata smiled, not too surprised given what she had seen the previous month with the woman's student. Still, to think that Kushina was truly that much of a slut that she'd allow another man besides Minato to get her pregnant was astonishing in its own way. Hinata could never do that. She loved Naruto too much to even think about trying such a thing. She could never betray her husband like that... She'd watch Kushina do it, though, and enjoy the show all the way.
"Thank you, oh, I'm so excited. There's so much we going to have to buy. Maybe we'll even have a little girl this time!" Kushina almost squealed excitedly as she reached out and grabbed Minato's shoulder. "C'mon, Minato, let's go tell Mikoto!"
Watching as the older couple left, Hinata stared after them for a few moments, then turned her byakugan off with a sigh. Choosing not to even try and understand the thoughts of Naruto's mother. She doubted she'd ever understand how a woman could go from such a slut, cheating almost daily, to a loving wife spending time with her husband. Nevertheless, watching everything in the last few months and seeing Kushina's excitement confirmed one thing for Hinata.
"Hey, Naruto. Let's have a baby too."

"Minato, do you think something's wrong with Hinata? You don't think she and Naruto are having problems, do you?" Kushina frowned, a little concerned, having noticed Hinata acting strangely ever since the young woman married her son and moved in.
"No, at least I don't think so. I haven't noticed, and Naruto hasn't said anything." Minato shrugged. "It's probably nothing to worry about. They have their entire lives together. I'm sure it's nothing they won't overcome... The pitying looks she's been giving me lately are strange though."
"You noticed that too?" Kushina said and leaned her head against Minato's shoulder. "Oh well, she'll probably tell us in time."
"Yeah, or Naruto will. That boy can't keep a secret for the life of him." Minato agreed, then paused. "Now, what's the real reason for us coming out here. I know Mikoto would have been the first person you told after Tsuunade confirmed your pregnancy."
Grinning at how well Minato knew her, Kushina held up her fingers, counting off. "Well, we did the rough thug, casual bathroom fling, and student lusting after his teacher's body, among others. So, I was thinking, how about you henge into the student's father this time? We can call him One, or maybe Fifty for his supposed age. He'll be mad about his son daring to knock up the Hokage's wife and end up being seduced by me instead. What do you think?"
"...I think we need a vacation. We've transformed into more characters in your roleplay creations in the last few months than we have all year." Minato smiled, amused at Kushina's new idea. "I don't think I've personally stepped into my office in the last four months. It's just Hiruzen there with my shadow clone."
"Hey, we both know it's for good reason." Kushina huffed a playful sparkle in her eye. "Naruto and Hinata keep driving me crazy. Those two can't keep their hands off each other. It's terrible."
"Yeah, yeah..." Minato nodded as he pressed a kiss against the top of his wife's head, then brought her focus back on the topic. "So, you were talking about creating a father for Zero..."
