Summary: With Aiko and Nagisa away on a Father/Daughter trip for the weekend, Tomoya and Sanae are alone in the house by themselves. When Sanae runs into Tomoya and knocks him to the ground, inadvertently grinding her ass into his crotch in the same instant, the man demands she take responsibility for the hard on she's created.

One's Mother-in-Law  

Tomoya Okazaki let out a yawn as he slowly padded his way through the small home of his girlfriend’s parents. Nagisa Furukawa and her father Akio were away on a Father/Daughter trip for the entire weekend, so it just made sense for him to stay over at their place to help Nagisa’s mother Sanae around the house. It didn’t help that her mother was every bit as much a looker as her daughter. Tomoya loved Nagisa, but that didn’t stop him from lusting after her mother. Sanae was a MILF, plain and simple.

He turned the corner, still trying to blink the sleep out of his eyes, and suddenly the woman in question was there, turning the corner at the same time. They collided right then and there and Tomoya reacted almost instinctively, wrapping Sanae in his arms and spinning around in midair so he would land on his back and she would land on his chest, unhurt.

This had the effect of grinding her jean-clad ass down on his crotch though, and that combined with the lustful thoughts he’d just been entertaining about his girlfriend’s mother had his pants tenting in no time. After a moment of both catching their bearings, Tomoya knew Sanae felt how his body was reacting to him, because she suddenly tensed up, no longer squirming against him and then tried to pull away.

“A-ah, s-sorry Tomoya! I wasn’t watching where I was going, I need to be more careful, my apologies!”

But in that moment, the blue haired young man is having none of it. He’s done just thinking about fucking this beautiful older woman that’s currently pressed up against him. Before she can escape his grasp, Tomoya tightens his hold on her and leans in close to her ear, blowing lightly across it and then speaking.

“You can’t just leave me like this. You have to take responsibility for your actions.”

Sanae turns to face him, eyes wide but also with a light flush across her face. She glances between his eyes and down at where his crotch is touching her ass a few times before slowly nodding.

“I… yes, I understand.”

Slowly, she pulls back and Tomoya lets her go. The brunette slides off of his body and down to the floor, lying between his legs as he sits where he landed and doesn’t dare move a muscle. The older woman reaches out and pulls down his drawstring pajama bottoms until finally his cock flies free of the loose confines and springs up to almost smack her in the face.

Sanae’s eyes are wide as she takes in the full length of her son-in-law’s member, but she doesn’t hesitate for more than a few seconds. Licking her lips, the MILF grabs his cock by the base with one dainty hand and curls her hair behind her ear with the other. Then she leans forward and closes her eyes as she places her lips around the tip of his prick.

A guttural groan escapes Tomoya’s mouth as the beautiful older woman gets to work sucking him off. For her part, Sanae is blushing even deeper as she takes the dick into her mouth. The dick that didn’t belong to her husband, the dick that meant she was cheating on him. She couldn’t help feeling a little hot over that, her pussy slowly getting wet even as she bobbed her head up and down on Tomoya’s cock.

She is betraying the vows she swore on her wedding day, but Sanae can’t bring herself to care. She’s noticed her son-in-law before. He’s a strong well-built young man with a good head on her shoulders. The MILF was happy that her daughter had managed such a fine catch, but that didn’t stop her from blowing the girl’s husband right here in their hallway.

Sanae moaned out around Tomoya’s cock, sending vibrations through his girth and drawing a grunt from his lips. She was such a scarlet woman, but in that moment she didn’t care. She wanted Tomoya to use her, to enjoy her. When his other hand curled into her hair and he gripped her head tightly, the brunette let him do as he please. 

That meant gagging around his cock as he began to really fuck her throat, panting heavily all the while.

“Getting… getting close. Take it you fucking slut, take it!”

And so she did, moaning in between choking as he face fucked her, until a few moments later he was cumming in her mouth. Sanae gulped down every last drop. She truly was such a lewd woman. A… fucking slut, as Tomoya had called her. Her son-in-law suddenly pulled free of her mouth, but immediately Sanae saw the problem. He was STILL hard somehow. The two stared at each other for a long moment and then Tomoya’s lips curled into a wicked smile.

“You’re going to have to do more to make up for all your teasing. All this time, you’ve been hiding just how much of a pervert you are, haven’t you? I’ll need reparations for that.”

Blushing furiously under his intense glare, Sanae bit her lower lip, worrying it for a moment and then nodding. Slowly, the MILF got to her feet, standing up and undoing the button and zipper on her jeans. She was facing away from the still seated Tomoya when she slowly began to pull her pants and her panties down at the same time, sliding them from her waist and over her wide flared hips and bouncy bubble butt.

However, before the older woman could get any farther than her knees, a body suddenly impacts her owns. A surprised gasp escapes Sanae’s lips as she’s thrown forward onto the ground, ending up on her hands and knees with Tomoya over her, holding her in place with his strong masculine form, already grinding his incredibly hard prick against her bare naked ass.

Another moan escaped Sanae’s lips as she wiggled against his rubbing, her pussy getting all the wetter.

“O-Oh T-Tomoya…”

The younger man didn’t dignify her words with a response, but then he was already focused on guiding his cock to her waiting pussy lips. Sanae’s eyes widened as he pushed inside of her. He was so much bigger than Aiko, and as inch after inch of his member slid into her cunt, the moan became continuous, interspersed with quiet cute gasps as she struggled to adjust to his size.

“S-so b-big!”

The MILF had never felt fuller than in that moment, as her son-in-law sheathed his huge length inside of her, only to pull out and then do it again. And again and again, Sanae’s eyes getting even wider still when Tomoya finally began to truly fuck her. They were having such bestial sex right in the hallway. He was fucking her from behind with her pants holding her legs tightly together and there was nothing Sanae could do but kick her feet up and down and take it.

“You’re, hah, tight for such a, hah, lewd woman.”

The words sent her right over the edge. Just those two words, combined with everything they’d already done so far. Sanae’s mouth fell open in a silent cry and she came hard right then and there, her pussy flexing around his cock as she rode out his orgasm. Tomoya actually paused, and his next words were a little incredulous.

“Did you just climax?”

Sanae was humiliated and embarrassed, ashamed of herself… but at the same time, she was all the more aroused by those feelings. Unable to get the words out, the brunette woman just nodded shakily, coming down from that first orgasm slowly. After a moment, Tomoya gripped her ass cheeks and began to truly rail into her, grunting as he thrust into her far harder than before, fucking her almost savagely in comparison to the relatively sedate pace he’d began with.

“Such a perverted cunt. Who knew that Nagisa’s mother was such a woman? You need to be punished. You need to learn how to be a proper slut and not fall so easily to the first man that propositions you. I’ll have to teach you, but for now… you will have to carry my child. I’m going to cum inside of your womb and fill you with a baby. Do you understand?”

The MILF nodded faster this time, her head moving up and down rapidly as he continued to fuck her.

“Ooh yes! Yes! Do it Tomoya! Fuck a baby into me! A-ah!!! You’re so deep inside of me Tomoya! You’re so much better than my husband. I c-can’t take it! I’ll give you as many children as you want Tomoya! I’m yours to use and fuck however you l-like!”

His thrusting became erratic and uneven, his pace catching as she spoke. Then, he pushed as deep inside of her tight passage as he could get, and Sanae felt her amazing son-in-law cumming inside of her just like he’d promised. His white hot seed painted the inside of her womb, and the sensation caused Sanae’s eyes to roll back in her head as she came a second time as well, an ugly cry escaping her lips. Her entire body shook under him with the force of the orgasm, and by the time she was done, he was as well, pulling out of her as his cock finally began to soften.

His hand was suddenly in her hair, firmly yet gently pulling her head around so he could kiss her on her lips. Sanae was surprised at first, but melted into the younger man’s kiss quite easily, happily reciprocating as he planted a big loving kiss on her mouth. There was no going back for the married woman now. She was officially in a relationship with her son-in-law. She’d promised him children, in the heat of the moment. But for some reason, Sanae couldn’t find it in herself to feel guilty over it. 

It felt right.

Nagisa stepped inside the small home and smiled as she found her mother and husband standing side by side, waiting to greet her. A moment later, her father stepped inside after her, carrying their bags. Her mother smiled happily at the two of them.

“Welcome home. I hope you both had a good trip!”

The smaller brunette was quick to nod excitedly. She immediately launched into the exploits her and her father had gotten up to, much to the amusement of the rest of the family. The young woman might have reacted differently if she’d known that her husband had christened every place in the small home with her mother’s body over the last two days.

Unbeknownst to both Nagisa and Aiko, Tomoya and Sanae had each other’s hands clasped together behind their backs, fingers interlocking between the two lovers.
