****** Satan Sex ******
by KR_CHROME86
Summary
     Rena Ryuugu accepts that satan loves Shinichi Banabara. So, Satan and
     Shinichi have sex
“Sa-chan, you love Shin-kun, don’t you?” Rena asked the demon girl as they had
tea together and the pale-haired girl with red eyes choked on her drink.
“W-w-what!?”  Satan gawked at the auburn-haired girl. “Don’t be silly! Why
would I love that guy? He’s a stupid pervert!”
“He’s also a hero who saved everyone,” Rena reminded, “And don’t lie Sa-chan.”
Her expression turned dark and scary, I hate liars.” Satan was actually
intimidated that she could see all the whites of Rena’s eyes as her pupils
dilated.
“Well, perversions aside, he can be sweet,” Satan said. “I mean he considers us
friends and I do care about him.”
“He cares about you too,” Rena pointed out. “That’s the way Shin-kun is.”
“OK, so I love the guy. Then what? It’s not like we can have a relationship.”
Satan’s expression saddened. “He’s faithful, to you. Even if he desires to have
sex with other girls he would never actually do it because he’s completely
devoted to you.”
“Yes, he is, and that means he will do anything I ask him to,” said Rena. She
then grinned as an idea crossed her mind. “Sa-chan, I have an idea.”
===============================================================================
“Shin-kun, we love each other, right?” Rena asked Shinichi as they sat at the
kotatsu together.
“Yeah, we do,” he replied.
“So, you will do anything I ask, right?” Rena pressed on.
“Yeah, of course, within reason,” Shinichi answered.
“OK, so tonight I’ll let you have sex with Sa-chan.”
Shinichi dropped the book he was reading and his jaw dropped as he stared at
his girlfriend. He picked at his ear. “Um…can you say that again? Because I
thought you said…”
“I’ll let you have sex with Sa-chan,” she repeated.
“There, there it is,” he pointed out. “Are you serious?” he asked suspiciously.
“Yes, I am.”
“This is a trick, right? Or a test. It’s a test, right? There are hidden
cameras, aren’t there?” He looked around for any hidden video recorders.
Rena put a comforting hand on his. “It’s not a trick or a test. I am allowing
you to bring another woman to our bed.”
Shinichi just stared at her speechless.
“So, go and call her!” Rena chirped.
===============================================================================
“Then, I’ll leave you both to have your fun. Oyasumi!” said Rena cheerfully
before closing the door.
“Oi, matte!” shouted Satan but Shinichi held her shoulders and she turned to
look at him. “Are you really going through with this, baka?”
“I thought she was joking before,” said Shinichi. “I didn’t think she was
serious.”
“She was,” Satan confirmed. “She asked me about it and I, for some reason,
agreed.”
“She’s very persuasive, kinda like Kaa-chan. Maybe that’s why they get along so
well,” Shinichi replied.
“So, are you going to go through with this?” she asked, blushing with
anticipation.
His eyes narrowed as he asked, “Do you know how many times I’ve dreamt of
ripping the clothes right off you and fucking you on the spot?” Satan’s eyes
widened and she blushed as her heard this. One hand went down to her chest and
squeezed one of her breasts, causing her gasp. “Loads and loads of times,” he
growled.
“Wait,” she whimpered. He pushed her onto the bed and got on top of her, on his
hands and knees as he looked down at the Stake of Wrath. “Shinichi.” He leaned
down and shut her up by claiming her lips, laying his body flat over hers. She
moaned as she felt his tongue force her lips apart and dive into her mouth. Her
cheeks were flushed and her eyes were screwed shut as she clenched on the
sleeve of his jacket. He massaged her breasts with one hand while the other
went between her legs and rubbed her sweet spot through her clothes. She gasped
in surprise and her eyes opened as she stared at him. He removed his lips from
hers and nibbled on her ear. “Y-you p-pervert!”
He whispered, “I am, which is why I know how to do this.” He massaged her
lewdly, enjoying the moans she was producing before he stopped and rolled off
her. Satan panted, putting a forearm over her sweaty forehead. Her chest rose
and fell. “Now, strip off your clothes,” he ordered. He grabbed her by the arms
and pulled her up from the bed and then made her stand before him as he sat at
the foot of the bed. “Strip,” he ordered.
Satan didn’t know what came over her but she did as commanded. She first took
off her blazer and let it drop to the floor and then she removed her vest. She
undid her tie and it slipped out of her fingers before she unbuttoned her
blouse and it too joined the rest of her clothing. Shinichi’s eyes were on her
and she looked absolutely delicious in her leotard which hugged her frame. She
removed her boots, one at a time, and was about to unzip her leotard when he
suddenly lunged for her. She cried out as she was slammed against the wall.
“Now, the fucking starts,” he whispered into her ear as he touched her right
thigh and left breast. He kissed her roughly and she wrapped her arms around
his neck as he hooked her right leg around his waist. He massaged her left
breast roughly, but not painfully. Satan couldn’t believe she was even allowing
this to happen. He then turned her over and ran his hands up and down her back.
He grabbed the skirt and tore it off her body before grabbing her ass. She
cried, her hands against the wall, and arched her back.
He pulled down the zipper on her back and then pulled down the top of her
leotard to expose her breasts and her upper back. He kissed her back and
grasped her breasts, rolling them around in his palms. Satan moaned, her mouth
wide open. It felt so dirty but it felt so good. Taking one hand away from her
huge melons, he slipped his fingers under the fabric between her legs and
smiled as she gasped. She was already wet.
As tempting as it was to take her from behind, he wanted to look at her face as
he pounded her into an orgasm. He turned her body around and looked her in the
eye before kissing her once more. She returned the kiss and hooked one leg
around his waist. She then heard him unzip his pants and looked down to see his
manhood. She had heard Lucifer, Asmodeus, and Leviathan talk about the size
their men sported but Shinichi’s package was definitely boast-worthy.
He started to attack her breasts with his hands and mouth, sucking on her
nipples like a newborn. Pleasant shudders coursed through her body. “D-don’t
stop!” He smirked. She was ready.
He stretched the fabric away from her pussy and speared her in one go. Satan
screamed at the sudden penetration and wrapped her arms tight around Shinichi.
He didn’t move as he wanted her to get used to his size. Tears fell from her
eyes due to the pain. Did losing her virginity really hurt this much?
“Don’t cry,” he told her. She looked at him as he smiled tenderly at her. He
then began to move his hips, thrusting in and out of her pussy. She held onto
him for dear life, thinking she would fall to her doom if she let go. She felt
her pleasure rise with each thrust. The descriptions from her sisters paled in
comparison to this. He hooked the other leg around his waist and held her ass
as he continued to thrust his hips against hers. Her eyes were closed as he
bounced her up and down his shaft. “You look so cute like this,” he said.
He carried her over to the bed and laid her onto it with her legs dangling from
the edge as he withdrew. “No! Put it back in! Please!” she begged.
“Just need to take care of something first,” he said as he kissed her. “It’s
time to make love to you.” She blushed and nodded. He helped slide her arms out
of her leotard’s sleeves before slipping it off her body. She was now nude save
for her garter belts and stockings. They just made her look sexy as he stared
at her with lust-filled eyes. She averted her eyes.
“Don’t look at me like that, sukebe!” she scolded him. She cried out as he
thrust into her once more, standing over her. With each thrust, her breasts
bounced and he held onto them for leverage. Her face was flushed red as she
clenched the sheets and started moaning.
The door to the room was ajar and Rena watched. She was really turned on by
what she saw that she was masturbating. “Go on, Shin-kun. Give it to her.”
He knew Rena was watching and gave her a wink before he picked up speed,
thrusting in and out of Satan faster and faster. She cried out, “Ah! Ah! Ah!
Ah! Oh yeah! Fuck me! Fuck me!” She shouted, “Harder, damn it! Fuck me harder!”
He held her by her hips and granted her wish, thrusting so hard her breasts
bounced up and down, making slapping noises. Finally, she arched her back as
she could no longer contain her orgasm. She splashed the seats and Shinichi
withdrew, shooting his load onto her breasts and stomach, some of it landing on
her face. She panted, her chest rising and falling, as she tried to catch her
breath. She was covered in sweat and cum as Shinichi leered at her.
Rena entered in her birthday suit and leaned against Shinichi’s flank. She too
looked down at Satan. “So, how was she?” she asked.
“We enjoyed ourselves,” said Shinichi. Rena held his cock in her hand and was
stroking it back to hardness. She then knelt before him and licked up at his
wet cock, which was slick with his and Satan’s mixed juices. He looked down at
her and rubbed her head as he said, “We better get her cleaned up. Then we can
go to round two.”
She released his cock with a pop, “Round two?”
“Three-way,” he answered simply. Rena grinned.
“I like the way you think.” She looked at Satan who was still experiencing the
afterglow of the sex she’d just had. “She looks so cute. I’m so glad I took her
home.”
“I’m glad too, because now we have an extra playmate to make things more fun.”
===============================================================================
When Satan awoke, she found herself pressed against a pleasantly warmed
surface. Groggily, she snuggled up against it.
“Good morning, Satan-chan.”
Satan’s eyes opened and she found herself staring at Shinichi Banabara. She
gasped and screamed in shock as she tried to move away but a hand around her
waist kept her close. “Lemme go you perverted bastard!” she screamed at him.
“That’s not you said last night,” he reminded. Satan blushed as she recalled
their activities. She settled down. “That’s a good girl.”
“Urusai,” she muttered, eyes cast down. He ran his hand up and down her side.
“So, we did…”
“Yup, we did, and let me tell you that you’re one really good fuck,” he told
her.
She didn’t respond but then she realized they weren’t alone in bed. Rena was
lying on Shinichi’s body too. He was between them, under the covers. She
remembered more of what happened last night. After she recovered, they had a
threesome, a really hot threesome that involved kissing, groping, sucking,
licking and lots and lots of fucking. Satan’s throat fell sore from all the
screaming she did as she had her breasts sucked by both Shinichi and Rena as he
fucked her pussy.
She remembered the position he made her take. There was doggy-style, cowgirl,
reverse cowgirl, and then there was the 69 position where Rena was on top of
her. Shinichi would fuck Rena first and when he was done with her he would roll
them over and fuck Satan.
“You’ve turned me into a pervert,” she accused. He then kissed her.
“You enjoyed it, admit it,” he said.
Rena saw the kiss. She hadn’t really been asleep and whined, “Mou…Shin-kun,
kiss Rena too.”
“OK.” Shinichi pulled her over for a kiss, his hand on her hip. Satan watched,
licking her lips as she watched the tongue play. Shinichi and Rena broke their
kiss and Shinichi turned to give Satan another one. She reciprocated it. He
broke the kiss and asked, “So, how about a quickie before breakfast? Or maybe
we can do it in the bathtub? Whaddya say, girls?”
===============================================================================
“So, last night I was in a three-way, my first one,” Shinichi told Yuji. “With
Rena-chan and Satan-chan.”
“Nice,” Yuji complimented.
Satan and Shinichi reached a mutual agreement. Satan would not try and steal
him from Rena. They were more like fuck buddies, friends with benefits. They
would be on friendly terms but if she wanted to have sex she was welcomed to
ask and he would welcome her into his bed or whatever was available. Rena
certainly didn’t mind. She loved to share with her friends as long as they
didn’t try to steal Shinichi away from her. That was why she didn’t get along
with Sakura. That girl, Shinichi’s childhood friend, only wanted him for
herself and so did Electric Butterfly. She hated those girls for wanting to
selfishly steal Shinichi away.
“It was awesome,” Shinichi said.
“Told you so,” Yuji smirked. “Nothing beats having more than one girl all over
you in bed.” He wiped an imaginary tear away from his eye, “My little Satie is
growing up…I’m so proud! I’m glad it was you that was her first and not some
stranger.”
Shinichi smiled, “That means a lot, Yuji. Thanks.”
===============================================================================
Satan grumbled. She felt sore. “Damn it, that bastard was too rough.” She
limped because her hips and thighs were sore. “That perverted bastard had his
way with me.”
“And you enjoyed it,” Asmodeus chirped.
Satan blushed and shouted, “YES!”
Yuji was resting on a couch and chided, “Nothing to be embarrassed about,
Satie.”
Satan shivered as she recalled her experience, “He knew how to touch me, when
to be rough and gentle, and how to treat me. Why the hell did I fall in love
with that idiot!?”
Yuji shrugged, “Because you saw him as a nice and friendly guy. You just didn't
see his pervy side until now.”
Asmodeus floated over to Yuji’s lap, “What was your first time like, Onii-
sama?”
“I was raped in my sleep,” he answered like it was nothing. The two girls
gasped.
“You…were raped…?” Satan repeated.
Yuji sat up and patted his other lap, beckoning Satan over. She blushed but
obeyed as she sat on his right lap as Asmo took his left. He had around their
slender waists and began, “It was when I first met Leon and become a Mystic
Rider. I met this girl, a succubus, named Morrigan. She was hot, true, and she
had a rack that could match my mom; which is no easy feat.”
“Is she the one who took your innocence?” Asmo asked cutely.
Yuji shook his head, “No, her sister did; Lilith. You know, the loli, with the
delicious ass?”
Asmo giggled, “She’s funny!”
“Well, I was asleep on the train and she took advantage of me,” he frowned, “I
didn’t know who she was and knew nothing about her. We didn’t talk after that
for some time.” He then showed a serene smile, “But I really did come to love
her for who she was.”
Satan saw how Yuji smiled when he spoke about Lilith. It seemed that she was
very important to her.
Yuji looked to the Stake of Wrath, “And yes, she is very important to me.”
She flushed, “Stop reading my mind!” Asmo laughed.
