Prompt: Spicing Things Up (Highschool DXD) (Patreon)

Summary: Rias was contacted by Issei's parents, Gorou and Miki. The two wanted to speak to her as soon as possible, and she arrived at their home promptly. She had no idea what they needed from her was some spice to their relationship. If she had known, she'd probably have come sooner. Includes: Threesome, Age Difference. 

----

Rias stood outside the bedroom, waiting for those inside to respond to her knocking. Her foot tapped impatiently on the ground as she waited.

Issei’s parents had contacted her, asking her to come see them as soon as possible. Rias, wanting to get along with her future in-laws, agreed and arrived at the Hyoudou Residence as quickly as possible. 

Of course, the fact that they were now making her wait frustrated Rias to no end. She knocked on the door, waiting for a response, but when that didn’t come, she finally just pushed the door open herself and stepped in.

She opened her mouth to greet them, only for the words to die in her throat. Her eyes widened as she found Gorou and Miki naked, their arms wrapped around one another as they kissed on their bed.

They noticed her barge in and the happy couple pulled apart from one another. Their cheeks were a subtle red, but beyond that, they seemed perfectly fine with her intrusion. They smiled as Rias finally found her voice.

“W-why are you naked?! Is this why you call me in for?!”

“Not exactly,” Gorou chuckled. “We actually wanted your help and we knew you were just the girl for the job.” His wife nodded her head, smiling at Rias. 

“It’s true. You see, dear, we’ve been wanting to spice things up for us, and we thought a threesome with a beautiful girl like yourself would be just what we need.”

“You’re perfect for it!” Gorou added. “Beautiful, sexy, and accepting. The perfect girl.”

Well, she certainly was that. Rias glanced away, staring at the wall of the bedroom as she considered their offer. She was glad Issei wasn’t around. He’d probably react poorly to seeing her even consider the proposition. 

Rias was in the mood for some fun when they contacted her, and when she glanced at the two, she did find them to actually be easy on the eyes. Both of them. Gorou was a handsome man for his age, and it was clear where Issei got his charming appearance from. Not to say Miki was bad. She was pretty gorgeous, aged like a fine wine to be even more beautiful.

Her breasts were nice, she had a curvy figure, and her face had an alluring charm of it. Like a mother next door who needed a good fucking.

In the end, Rias choice was pretty obvious. She accepted, walking towards the two as she stripped off her clothes. She undid her buttons, slowly exposing more and more of her cleavage as she smiled at the couple.

“Alright. If you two think you can take me.”

Her skirt fell to the ground and the redhead kicked it away. She shrugged, letting her shirt fall to the ground. She stood before the two in her underwear, and Miki stood up to help the younger woman take the rest off.

Gorou watched with an eager grin as the two women kissed one another. Miki undid Rias’ bra, and helped the redhead toss it aside. Miki then grabbed Rias’ underwear and bent down to her knees, pulling it down. Rias lifted her legs out of it, allowing Miki to kiss her legs, before joining her on her knees.

With both of them on their knees, the two kissed, their tongues wrestling as their hands explored each other’s bodies. Rias groped the mother’s breasts, and Miki did the same, feeling the woman’s slightly larger tits. They moaned as Gorou watched, licking his lips.

Miki’s fingers pinched Rias’ nipples as the redhead moaned. The demonic woman moved her fingers down the older woman’s body, reaching down to her pussy. Rias began to finger Miki, pushing a single digit in and out of the younger beauty. 

Gorou watched the two gorgeous women make out, and he began to touch himself to the sight. His hand went up and down his already throbbing cock. Both women glanced at the hard member, seeing it out of the corner of their eyes. They smiled as their lips pressed against each other, and after a moment, they pulled apart to marvel at the shaft.

Rias found herself licking her lips, nodding in approval. Gorou’s cock didn’t look half bad…

“Nice, isn’t it?” Miki moaned. “I’m a lucky lady, and so are you, Rias…”

“You two are lucky ones,” the redhead replied, and the two giggtled as they crawled towards Gorou. 

They were sitting on each side of it, and their hands continued to touch and explore the other as their lips connected to the sides of the shaft. They kissed lines up and down their respective side as their hands groped and touched the other. 

Miki’s hands slid down Rias body, outlining the hourglass figure of the woman. She gave Rias’ ass a squeeze, before her hands went to Rias’ pussy, one hand stroking and massaging her clit, while the other began finger the gorgeous student’s pussy.

Rias moaned, pulling her head back and biting her lower lip at the act. She looked at Miki over the cock, and the mother just winked at her, before she began to drag her tongue along the shaft. Rias grinned, before grabbing Miki’s tits in her hands and practically mauling them, kneading the firm, round flesh. Despite her age, Miki still had a wonderful pair of tits on her, and Rias made sure to enjoy their shape and size.

“Oh, fuck,” Gorou growled, placing his hands on both women’s heads. Rias smiled as he took command, pressing both women against his cock. She opened her mouth and suck on the side of the cock as Miki took the head, sucking on it as their hands moved.

Now both women were fingering the other, while their other hand groped and played with the other’s breast. Rias moaned as Miki pulled on her nipple, before the older woman pulled her head off of the dick.

“Suck it,” Miki ordered, and Rias obeyed the command with an eager smile. She brought her head down on the cock, sucking it as it stretched out her throat and slammed against her esophagus. As she sucked on the thick, hard member, Miki took it upon herself to give her husband’s balls a tongue bath.

She smacked her tongue against his testickles, cleaning them as pressed both women against his cock, loving the feeling of his son’s friend’s lips around his dick. Her tongue smacked the underside of his veiny shaft, coating it in her saliva as his wife sucked on his balls, giving both of them a loving kiss.

He soon felt his orgasm coming, and he pushed Rias off of his cock as he put them both into place, staring down his shaft. “Here it comes…” Both women opened their mouths and closed their eyes. They stuck their tongues out as jets of cum fell upon their face, splattering onto their cheeks and on their stretched out tongues.

The shower of semen fell on their faces, giving them a delicious facial as both girls pulled their tongues back into their mouths and swirled their tongues around. They savored the same taste, before they kissed one another, trading semen and saliva between one another as they moaned  

Gorou’s jaw nearly dropped at the sigh. His heart raced as his cock throbbing once more. He had just came, yet he was ready to go again as he saw the two women sucking each other’s tongues, drinking semen from the other’s mouth. Cum and saliva dripped between their lips, falling onto their breasts as they pushed against one another.

They moaned together as they slurped the last of the semen down their throats and looked at Gorou expectantly. He grinned, and patted his lap.

‘Rias, come up here. You’re gonna ride me.”

“Yes, sir…”

Rias got on the man’s lap, and his cock slipped into her pussy without any fight. She moaned as he laid on his back, letting Rias do all the work as she moaned and writhed. She sank lower and lower down the shaft, until her ass was pressed against his crotch.

Her hands laid on his chest, stroking his muscles as she smiled at him. Her bangs clung to her sweaty forehead as she licked at her lips, little hearts dancing in her eyes as gazed upon the man. 

“You’re… so big.” He smacked her ass, nodding his head in approval as she began to lift herself up the cock. Her pussy walls clung to the shaft as she went up the member, before bringing herself back down on the cock.

Miki smiled at the sight of her husband fucking the young woman. She licked her lips as she got on the bed, sitting herself down behind Rias. Miki placed her hands on the redhead’s chest, groping her tits from behind as Rias moaned loudly.

“He’s amazing, isn’t he? One of the reasons I married him.”

“You’re not so half bad yourself. Not your first time with a girl?” Rias asked, glancing at the mother. 

“I was young once too, you know. I experimented when I was younger.” Miki and Rias shared a kiss before Gorou’s eyes, and he growled in approval as he took Rias’ hips in hand and began to fuck her herself. 

Rias was shocked at the human’s strength as he lifted her body up and down his shaft. She moaned into Miki’s lips as he picked up speed, moving faster and faster as the tip of his cock kissed the entrance to her womb. 

His member was stretching out her pussy, sliding along the moist and wet walls of her womanhood as his wife kissed Rias. Miki’s tongue explored the other woman’s mouth, still tasting a bit of Gorou’s semen. The mother’s hands continued to maul and grope Rias’ chest, and it wasn’t long until she was cumming on the cock. 

Her tight pussy quivered, and her muscles tightened around the shaft, squeezing it with the warm walls of her cunt. Her nails dug into Gorou’s chest as Miki’s lips muffled the loud cry. Gorou let out a low groan, before he came inside Rias, filling her pussy with his semen, coating the walls just like he had coated Rias’ face. 

Cum filled the demonic woman’s womb as her body trembled. She quivered atop the cock, before she went limp. Miki was the only thing holding her, and  she released Rias so the younger woman could fall on Gorou, her large breasts pressing against his chest.

“Oh, fuck,” she panted, trying to catch her brath as Gorou squeezed her ass. “That was…”

“Heh. I know. I’ve never had complaints before,” Gorou commented. He glanced at his wife, grinning as he said, “Your turn.”

“I’ve got a better idea,” Miki replied, grinning as she pulled Rias off of her husband.

Soon both women were laying on top of one another, with Miki on the bottom and Rias on top of her. Their breasts pressed against each other as Gorou sat on his knees, moving his cock up and down as he debated which hole to take first. 

“Put on a show for me, you two. I want to see you two kiss like you were a couple of lesbos.” Rias blinked as Miki giggled. 

“A fantasy of his,” she explained, and Rias nodded her head in understanding as the two kissed one another. 

Their lips pressed together as Gorou plunged his cock into Rias’ pussy. The woman moaned, wrapping her arms around Miki as the thick shaft plunged back into her womanhood. Miki held Rias the same way, and their tits smacked against one another as they moaned and made out.

Their tongues came out of their mouths, slapping and smacking against one another as Gorou thrusted his hips back and forth, fucking Rias harder and faster as his balls slapped against her body. 

He kept going, harder and faster, listening to their moans with a toothy grin. When he thought Rias was about to cum, he pulled his cock out and slammed it into his wife’s. Miki broke her kiss with Rias, and happily moaned at the sensation. Rias whined in protest, kissing Miki again, and sucking on the older woman’s tongue as their nipples prodded one another’s tits. 

Gorou placed his hand on Rias’ back, and his hand smacked into her ass. Rias cried out in pleasure at the blow, her face red as she thought about how… impressive a lover this human was. No wonder Miki chose him. If Issei was half this good…

Her thoughts on Issei faded as Gorou continued to pump into his wife, pounding her pussy faster and faster. Rias and Miki broke their kiss, and the former watched Miki’s face moan. She had a fucked silly grin on her face as her husband pounded her, slamming his dick against her womb.

“C-cum in me, honey! I-I want another baby with you!” 

“Then take it, slut!” He grabbed Rias’ hair and pulled, forcing her back so that her tits were pushed into Miki’s face. Miki grabbed at one, sucking on the nipple as Gorou came again, filling his wife’s womb with his seed. 

Rias moaned as her nipples were assaulted by Miki’s hands and mouth. She felt the older woman’s tongue smack and wrap around her nipples as Gorou pulled his dick out of his wife, firing a few more jets of cum on their bodies. Then, without missing a beat, he slammed his cock into Rias and finished the job there.

Rias mewled, eyes rolling into her skull as Gorou pounded her pussy. His thrusts were frantic, rapid, and yet experienced. This man was an experienced lover, and Rias bit her lower lip as she was quickly pushed over the edge. 

She came on his shaft, feeling his semen fill her just as her climax hit her. She moaned loudly, screaming in pleasure as her body was pumped full of cum. There was so much that it dripped out of her pussy, spilling onto the bed as Rias’ body went limp again. Gorou dropped her, and Miki caught the young woman, caressing her head as Rias struggled to catch her breath.

After taking a small break, Gorou returned to sitting on his and his wife’s bed, happily watching as the two girls’ sat on their knees and gave him a double boobjob. They smiled at him, their beautiful faces still marked with his semen as they pressed their tits against one another. His cock stood in the middle, like a tower of flesh as they moved their bodies up and down the throbbing shaft. 

“Mmm, just like that, sluts,” Gorou moaned, nodding his head in approval as the two girls smiled. 

They leaned forward and kissed the cock from both sides. His dick was the only thing keeping their lips from touching, and they moaned as they dragged their tits up and down the sides of the cock, soon sticking out their tongues to lick the tip.

“Oh, fuck…” 

His orgasm was imminent, and the two girls shared a look with one another. Rias pulled away and Miki took the tip, bobbing her head down into Rias’ cleavage as the man came. He filled his wife’s mouth with semen, and her cheeks were filled with his seed. Once her mouth was filled, Rias quickly replaced her, catching his seed in her mouth, before she sealed her lips around the tip.

Not a single drop of cum fell on the ground, and the two women moaned as they savored the taste, before kissing one another, swapping saliva and semen once more for Gorou’s entertainment. 

Eventually the two women licked each other clean, and they laid on the ground as the older man slid down to join them, sitting by his wife’s side. Rias was panting as she laid on her back, her eyes locked on the ceiling.

After a few moments, she spoke. “If you want to do this again, just ask. I’d be happy to spice things up for you again...”

Miki was surprisingly quick to reply. “Well… What’s your schedule tomorrow?” 

Rias’ eyes widened, before a smirk formed on her lips. “Oh, I’m free all day.”
