LEMONS WARNING
So after that day where Issei finally confessed to Rias, He was laying down on his bed, talking to himself.
Issei: (sigh) So I've finally done it. I've finally confessed to her.
Issei closed his eyes.
Issei: This week was tiring...I need to rest...All that fighting really drained me.
A couple of knocks came from Issei's door.
Issei: Yes?
The door opened. Rias walked inside.
Issei: ...Rias?
Rias closed the door and locked it behind her. She smiled. Issei made a worrying look.
Rias: Issei...We're finally home alone you know?
Issei: ...Yes, I suppose we are.
Issei dropped a sweat. Rias stepped closer and unbuttoned her shirt. Issei was staring.
Issei: Whoa...
Rias: Issei...what are we now?
Issei: ...Uhm...I guess we're boyfriend and girlfriend now?
Rias giggled and dropped her shirt. Her large breasts bounced. She unhooked her bra, releasing her big bouncy breasts.
Issei: OOH WHOA!
Rias rushed to Issei and pinned him down.
Issei: HAAA?!
Rias: Now Issei... Please... Let me reward you..with my body.
Issei: ...Are you sure about this? I mean we are in a relationship now right?
Rias: Oh, of course, Issei, you can have anything you want.
Issei was smiling like an idiot.
Issei: THEN YES! I'LL CLAIM YOUR REWARD AND TREASURE IT! HAHAHA!
Issei hugged her tightly squeezing her.
Issei: FINALLY! I CAN FINALLY GET AS CLOSE TO THE HOTTEST CHICK I KNOW!
Rias turned red and giggled.
Rias: Slow down Issei... We have to take it slow first.
Issei looked up at Rias.
Issei: Oh my bad. How should we start then?
Rias climbed on top of him. She slowly leaned in.
Rias: Like this...
Issei: Ooooh...
They both leaned in and kissed.
Issei: (This feels amazing...her body is on me...just like last time on the sauna. Her boobs are pressing onto my chest. The wonderful sensation of Rias' tongue colliding against mine! Oh the sweet sensation of HER BODY ON ME!)
Rias: Mmmmmmmm...
Issei: (Her sounds...it's very arousing...I'm getting too excited. I have to calm down. She wants it slow first.)
They both made out for a while. Issei broke the kiss to breathe. Rias looked at him and giggled.
Issei: R-Rias...
Rias giggled.
Rias: I love it when you call me by my name...
Rias narrowed her eyes and smiled.
Rias: So, what do you say we get closer...
Issei: C-Closer?! Oh, you mean... No no what am I saying, you couldn't possibly mean...
Rias whispered in his ear.
Rias: Oh I do mean it... Let's do it right here Issei...
Issei squealed in excitement.
Issei: OOOOOOOOH! R-Really...Y-You mean it?
Rias giggled.
Rias: Of course...
Issei was shaking.
Issei: I...I...I don't know how to start this! Rias this is too sudden... I'm too excited I can't think!
Rias giggled more. She rubbed his chest.
Rias: Would you like me to help you out?
Issei froze and stared at her.
Issei: (Help me out? Does she mean...)
Rias reached lower and rubbed his crotch.
Issei: GAAAH! R-RIAS! THAT'S THAT'S MY...
Rias unzipped his pants.
Issei: (She's unzipping my pants! OH MY GOD! I FEEL LIKE I SHOULD STOP THIS BUT WHY WOULD I?! THIS THE CLOSEST I'M GOING TO GET TO POUND TOWN! WAIT...THAT MEANS SHE'S GOING TO SEE MY...)
Rias pulled out his meat. Issei turned red in embarrassment.
Issei: AAAAAAH! RI-RIAS! THIS IS EMBARASSING!
Rias smiled as his meat grew bigger. Issei felt even more embarrassed.
Rias: It's wonderful... Fufufu~ I've seen it many times Issei but I haven't seen it this big and hard.
She starts to stroke it.
Issei: Aaaaa...
Rias: Does this feel good?
Issei: Oh baby... yes... it does...
Rias: Do you want me to taste it?
Issei: W-What?! WHAAAAAAT?!
Rias giggled.
Rias: Do you want me to taste it Issei? It's a simple question.
Issei: I...I'm lost for words...(SHE WANTS TO BLOW ME! COULD THIS BE IT?! MY MANHOOD IS ABOUT TO FINALLY GET INSIDE A GIRLS MOUTH! AND NOT JUST ANY GIRLS MOUTH! IT'S RIAS' MOUTH? THIS IS EPIC!)
Rias: Well? I'm waiting...
Rias stroked more and more. Issei moaned with pleasure.
Rias: Do you want it or not, this is the only opportunity you'll get.
Issei: (F-FUCK! I'M NOT READY FOR THIS! OH FUCK IT! I HAVE TO EXPERIENCE IT! I HAVE TO!) Y-yes...please...
Rias: Hmmm...Say it like you actually want it...
Issei: YES PLEASE!
Rias: Do you really want me to taste your cock Issei... Your big, hard, juicy cock inside my mouth... Oh, it makes me drool.
Rias' saliva dripped onto his meat. Issei was shaking like crazy.
Issei: (YES I FUCKING WANT YOU TOO!) YEEEEEEEEEES I WANT YOU TO SUCK ME DRY!
Rias blushed a little bit. She then grinned.
Rias: Alright, I'll let you have it.
Issei: (HAHA... SHE'S GOING TO DO IT!)
She slowly lowered down to his crotch. She then pressed her lips on the tip of his meat.
Rias: Chu~
Issei: (AAAAAAAAAAAAAAAAAAAAH SHE KISSED IT! AND THERE'S MORE TO COME!)
Rias slowly sucked on the tip of his meat. Issei moaned.
Issei: AAAH! R-RIAS! (AAAAAH THIS FEELS AWESOME!)
Rias: Mmmmm
Rias sucked a bit deeper.
Issei: OOOO RIAS!
Rias: Mmm...
Rias was looking at Issei as she was blowing him.
Issei: (THIS FEELING! THE GIRL'S MOUTH! ALL SLIMY AND WET! IT'S SO AMAZING! I'VE NEVER THOUGHT IT WOULD FEEL THIS AWESOME! I'VE FINALLY GOTTEN A BLOWJOB! IT'S THE BEST THING I'VE EVER EXPERIENCED!)
Rias sucked deeper and faster bobbing her head.
Issei: RIAS! I... THIS FEELING! (I'm going to blast...I have to warn her!)
Issei clenched his hands. Rias held his legs tightly and shove his meat all the way down to her throat.
Issei: RIAS! I'M GOING TO EXPLODE!
Rias slowly moved back and forth all the way down and up as she stared at him. She was blushing in deep red.
Issei: (Oh...her face...it's so arousing...it's...it's..aaah...AAAAAH! IT'S COMING! AAAAAAA!) RIAAAAAAAAAAAAAAAAAS!
Issei shot inside her mouth. Rias's mouth was full. She released his meat from her mouth. Saliva dripped all over. She spat the fluids out in a bin. She panted heavily. Issei was staring at the ceiling panting heavily.
Issei: That...was amazing...
Rias smiled at him and climbed on top.
Rias: ...What did you think?
Issei's nose started bleeding.
Rias: Issei?!
Issei then passed out on the bed.
Rias: Issei?! Issei?!
Later on, Issei woke up from his nosebleed situation. He sat up and looked around.
Issei: ...R-Rias...Was that a dream? Was that all that in my head?
Rias: I'm right here Issei...
Issei looked to his right and saw her naked next to him.
Issei: GAAA- So...So it wasn't a dream...
Rias sighed.
Issei: ...Is something wrong Rias?
Rias: It's nothing...
Issei hugged her.
Issei: Rias...I'm sorry...
Rias slowly hugged back.
Rias: You killed the mood...when you passed out.
Issei: Hey, you're the one toying with me! I can only handle so much!
Rias smiled.
Rias: I can't help it. I love to toy with you sometimes. After all, I am your master.
Issei: THAT'S IT! IT'S ABOUT TIME WE SWITCH ROLES!
Issei climbed on top of her.
Rias: Issei?
Issei: If we're couples now. I'll have to dominate you too!
Issei smiled and groped Rias' breast.
Rias: HAAA?! S-Stop it Issei! Aaaa!
Issei: It's my turn to play with you!
Rias: N..No! Stop it! OOH! NOT THERE!
Issei then pinched her nips and began to pull.
Rias: AAA STOP IT! IT HURTS!
Issei: NOTHING IS GOING TO STOP ME NOW RIAS! TODAY IS THE DAY I BECOME A MAN! I'M GOING TO SUCK DEM TITTIES DRY!
Issei slowly sticks his tongue out. He licked her nip. Issei then sucked on her nip.
Rias: AAAAAAAAAA! ISSEI!
Rias hugged him tightly.
Rias: Issei...Aaaaa! I-Issei...
Issei: (Her tits...The taste...I've never thought it would be like this... The sounds of her moaning...it arouses me more...I can't stop...I've completely weakened her. She isn't fighting back. She's allowing me to go keep going. Finally, I've dominated her.)
Issei groped her other breast and sucked on her nip.
Rias: I-ISSEI! AAAAAAAHAAA! AAAAAAAH! I CAN'T TAKE IT ANYMORE!
Rias pulled him off and kissed him passionately. Their lips locked and their tongues were violently swirling against each other. Rias broke the kiss. They were both panting.
Rias: ...That... That...was..intense...
Issei looked down.
Issei: Sorry...I got carried away.
Rias: N-NO! I...I LOVE THIS! I love this type of you.
Rias pulled him down on the bed and climbed on top.
Rias: You're so dominant... It's so sexy... But, now I have to remind you who's really your master...
Issei smiled.
Issei: Hehehe...Well then...What do you want to do with me?
Rias turned deep red. She stared at him rubbing his chest.
Rias: Oh... Issei... I feel so small now...
Issei: Oh...and I thought you were my master. Hehehehe.
Rias: Oh Issei... You've made me so weak and pathetic! I can't simply hold on to it anymore!
Issei: Wha?!
Rias: Please...
Rias slid her finger down his chest.
Rias: Please, take me... I want you to claim me in bed Issei...
Issei: Hmmmmm... I don't know if you deserve it.
Rias growled and flipped him over.
Issei: Oh? You're forcing me to do it?
Rias: ...Just, please.
Issei: Alright. As you wish.
Rias closed her eyes and spread her legs open.
Issei: (Focus...She wants it...You want it...Don't overthink...Just...Focus..I'm ready...I'm ready...I can do this...I can finally take her virginity...)
Issei whipped out his meat.
Rias: Please... Fuck me...
Issei: (The words I've been wanting to hear...for a long long time...)
Issei shoved his meat inside her. Rias screamed in pain.
Rias: AAAA! AAA! OOOOW! OW OW OW OW!
Issei pulled out.
Issei: RIAS?!
Rias: WHY DOES IT HURT SO MUCH!
Issei: ...I...I forgot...that you're a virgin. So it's going to hurt once we do it...I should have done it easier...
Rias: No...please...I can take it!
Issei: You're bleeding!
Rias got off the bed and stood up. Issei handed her a rag.
Rias: ...Issei...
Issei: Rias...
Rias hugged him tightly.
Issei: Rias...I'm I'm sorry...I didn't mean to hurt you. Now come on...let's get you patched up.
Rias: I...I don't need you to baby me!
Issei: Alright alright...I'll stay here if you need me.
So Rias went off to the restroom and Issei laid back down feeling horrible.
Issei: I can't believe this happened...Right when it was about to go down...
