Reiji's POV:
How deplorable, I can't believe those brats provoke me to perform a sexual intercourse on my girlfriend.
Ugh why must I have such deplorable men as my brothers?

I then let out a sigh tiredly from dealing with those idiot brats.

"Honestly, why must they bother me in a time like this? This "bet" is ridiculous, but...."

I then imagine the thought of me walking around in a pink speedo where everyone would laughed at me in school especially my brothers. Hey then snapped back to reality and cringed.

"Ughhh....I absolutely do not want to wear that crude outfit....."

I cringed as I kept on walking. I thought about Riki for a minute.

Speaking of which, I never have sexual intercourse with anyone before, but with Riki...hmmm....

I then thought about Riki where she would seduce me with her naked body, say lewd things to me, and scream my name while making love.

Reiji!

"Hm?"

I soon snapped out of my lewd fantasy when Riki appeared right in front of me in the hallway.

How deplorable...I'm becoming like Laito now.

I thought as I returned to my strict composure and pushed my glasses up.

"Is there something you want Riki?"

I politely asked as she looked at me with a slight tense look.

"Well...there is something that I would like to ask you, but....it would be nice if we could do it in my room privately...."

She stated awkwardly with a slight grin where I became slightly tense yet curious about it.

Privately?....I guess this is my opportunity to show these brats that I can do it....

I thought wisely as I pushed my glasses up, I nodded at her request.

"I don't mind talking to you in your room, so I'll be honored to hear your thoughts Riki."

Riki then smiled warmly at me.

"Thank you Reiji."

Kanato's POV:
While in the living room, I was playing with teddy until I have a bad feeling about Ayato and Laito cuz I'm starting to get aware that they're planning something.....

"You guys made a bet with Reiji didn't you?"

I asked skeptically.

"Yup!"

"We sure did Kanato."

They both grinned like idiots as I groaned and face palm at how stupid they are.

"You guys are total bakas."

I dryly remarked with a deadpan look.

"Hey at least we're smart enough not to fall to the floor like a total moron!"

Ayato shouted as I sighed.

"You may have a pout there, but why would you guys do that?"

I asked with an irritably look.

"CUZ WE'RE AWESOME!"

They both cheered as I sighed at how ridiculous they are right now.

They're such morons teddy.....

I thought while holding teddy in my arms.

"So what's the bet?"

I asked tiredly.

"Okay so here's how it goes: If Reiji bangs Riki today, then we get to do his chores, but if he didn't bang Riki, then he will wear a pink speedo in school!"

Ayato explained with a sly smirk as Laito snickered at the thought of Reiji in a pink speedo, I sweatdropped at how stupid their bet is.

Wow even Reiji would be stupid to take that challenge.....

I thought while sweatdropping.

"Why would you want Reiji to bang Riki anyway?"

I asked skeptically.

"To make him look like a jackass of course!"

Ayato then laughed at the thought of Reiji in the pink speedo. Even I let out a small chuckle at the thought of Reiji doing something stupid like this.

"Pfft okay that's kinda funny, but is that really it?"

I asked curiously, but Laito pat me on the head with a cheery grin.

"You'll learn it someday when you find your special someone Kanato."

He assured me cheerfully as I was getting irritated with Laito ruffling my hair.

"Can you not rub my hair like that? It's annoying."

I scoffed irritably with Laito putting his hands up to the air and Ayato is chuckling at the anticipation from the bet.

"Oh man this is going to be hilarious!"

Ayato chuckled with Laito smirking amusingly.

"~fufu~ Oh this is going to be interesting.~"

He smirked cunningly as I stood there sweatdropping at their antics.

This is going to be a pain teddy.....

I thought while feeling irritated with their stupid antics. I thought about Reiji for a minute.

Speaking of which, I wonder how Reiji is taking this?

Reiji's POV:
While in Riki's room, both of us we're sitting next to each other awkwardly in her bed where I was getting a bit strange about having sex with my sophisticated demon girlfriend.

This is such a waste of time, I can't believe those brats dragged me into this.

I thought irritably until I heard Riki talking to me.

"Reiji?"

"Hm? Yes Riki?"

I turned to her with a curious look where she twiddle her fingers nervously and looks at me with a slight smile.

"Do you know why I brought you here?"

She asked politely but smiled awkwardly.

"I do."

I strictly replied as she gets up from her bed, she stand upon me with a polite yet nervous smile.

"Well you see...Niki came to my room the other day and....she saw me reading this erotic novel that I'm reading...."

She awkwardly explained as I tilt my head curiously.

"And why would you read something like that?"

I asked curiously as she narrowed her eyes awkwardly.

"Well you see Reiji...I've been keeping this secret for a long time and...I have this strange yet irresistible thought of two people making love....even Niki is quite aware of what I'm thinking...."

She stated shyly with an awkward grin where I immediately understand where she's coming from.

"So you're saying that you have sexual fantasies about experiencing sexual intercourse?"

I asked curiously.

"Something like that, but...."

Riki then walked up to me and sat on my lap with a devious smirk.

"I want you to experienced it with you Reiji.~"

She cooed into my ear as I formed a callous smirk as while, I flipped her over and got on top of her where I took my glasses off.

"Then you better prepare for a private lesson because I'm going to dominate your whole body until you won't walk."

I whispered seductively as I gave her a light kiss on the lips, and smirked.

"You better pay close attention Riki."

I demanded her as Riki smirked amusingly and wrapped my neck with his arms.

"I'm looking forward to learn this lesson Reiji.~"

She smirked amusingly as she takes off her glasses as well, both of us are ready to make love.

****Warning: LEMON AHEAD SO GRAB A LOT OF TISSUES CUZ THIS IS GONNA BE ONE HELL OF A NOSEBLEED!*****

Nobody's POV:
While in bed, Reiji brings Riki into a deep loving kiss where it came off as steady, but eventually it became a French kiss.

As their tongues intertwined with one another, Reiji slowly unbuttoned her blouse carefully not to break the kiss as his hand went underneath her blouse. He then squeezed her left breast aggressively where she breaks the kiss with a gasp.

"Mmm~"

She moaned softly when he messages her left breast, Reiji smirked and his other hand reaches to the back of her dark purple bra. He then unclasped her bra and threw it to the dark corner exposing her big chest.

He thought while staring at Riki's exposed womanhood, Reiji gets down in his knees and caresses her clit slowly causing her to let out a loud gasp and moaned by his touch.

"Ohhhh yesss~"

She moaned in pleasure where Reiji smirked at her moans and kept on rubbing her clit to the point where he licks her womanhood sexily.

" *gasps* Yes Reiji! Aah~ I am a lewd woman! Ohh~ I'm such a lewd woman aah!~"

She confessed while moaning from Reiji fingering her womanhood. Reiji then pulled out his fingers and licked her cum off his fingers.

"Riki...*grunts* my god you're tight!"

Reiji grunted as he pounds her so hard, Riki moans so sexily until she felt something twitching inside her.

"Reiji...hit me...hit me right there please!"

She begged him as Reiji did what she said, Riki gasped and moaned by the undeniable pleasure.

"Oh yes! *sighs*"

"Cum on me Riki."

The next day later.....

"Ugh I fucking hate this!"

Ayato groaned as he rubs the floor with a dish rag along with Laito whom both of them are unhappy that they lost the bet from Reiji.

"This sucks Reiji!"

Laito whined childishly, but Reiji ignore their complaints and coldly spat at them.

"Less talking, more scrubbing!"

Reiji demanded as both of them groaned and continued with the chores. Then Riki giggled and gave her boyfriend a kiss on the cheek.

"Thank you for the private lesson yesterday Reiji."

She grinned sweetly at him.

"Anytime Riki."

He politely replied as he kisses her cheek as well causing Niki and Shu to groaned in annoyance who are lying on the couch together.

"Urusei."

Niki rudely shouted while lying on Shu's chest.

"You're all ruining our music."

"Those deadbeats...."

They both sighed as Riki leans her head to his shoulder with a loving smile.

"I love you so much Reiji."

She confessed lovingly.

"And I love you too Riki."

He lovingly stated as Reiji hugs Riki from behind, this was the best day for Reiji since he won the bet.
