Rin Okumura X Ryuuji Suguro X Fem!Reader

Demon Kink

Letting Rin Okumura and Ryuuji Suguro into her dorm room was a mistake from the beginning and she knew that but somehow both were failing demon anatomy, despite one of them being half-demon. She hadn't even started helping them yet before they were already at each other's throats. Sighing and giving up she used her tail, that she was able to have free in her dorm (thank god for making her stay in the boys dorm house with Yukio and Rin), to grab a perfume bottle (full of water for when she brushed her hair and because it was the only spray bottle she owned) that laid on her dresser and sprayed the boys in the face.

"What the heck!" Rin shouted. Ryuuji didn't look too happy either. "Look I offered to help you guys pass. I even talked to Yukio on letting you guys retake! So shut up and sit down before I actually chain you to the fucking floor!" Ryuuji and Rin immediately sat down. They've never seen y/n angry or even drop an f-bomb. Sure she's been close to it but never out fo anger usually from a joke. She made them pull out their failed tests while she positions herself in between them on the floor.

She looked at what they got wrong and right. "Rin how the fuck did Ryuuji get more right on the male demon section than you did? You're a fucking demon!" They already knew she was aggravated to the max and there was no pulling her back. That meant this session wasn't going to be as fun as both thoughts. "Well, Bon-" Rin tried to come up with an excuse. Y/n was the only one who called Bon by his actual first name despite his hatred towards it. "Look it seems like you have the gist of it you just messed up stuff about an incubus. Easy fix." She marked down the right answers for both of them.

They moved onto female anatomy which y/n aced considering she was a female demon herself. "You guys are really bad at this." She sighed. The guys haven't spoken a word afraid to be yelled at once again. "Okay, I'll give you a crash course in female demons." She opened the textbook to the exact page on her first try which made her anger go down just slightly. Little victories.

"Okay so basically we're the same as males just a few differences." Rin and Ryuuji were actually paying attention. Maybe it was because it's y/n or maybe the whole female demons are really hot. "We still have normal puberty cycle like normal females except we get a tail which can be used as a weapon or depending on the demon also a sexual whatever since it's still an appendage." She kept on but the boys weren't even listening. To be honest both boys liked y/n and it wasn't made obvious to her but to everyone else.

"Female demons can have multiple weak spots like neck and wrists. Female demons can have kids but it's harder for a chance for success." Rin has Ryuuji a knowing look. "So the neck and wrists?" Rin asked. She nodded in responded. "I know from combat that my wrists are sensitive but I've never actually figured if my neck was." With that being said Rin placed his lips on y/n's neck. She yelped out in surprise but ended up tilting her neck to give the demon a better angle.

"You know instead of books you could give us hands-on training?" The mohawked male said placing once of his hands-on y/n's legs. "Yeah, we all know I work for better hands-on," Rin said in between leaving marks on her sensitive neck. Y/n let out a light moan which wound up the two males. "I-I mean it would g-give you a higher chance of passing." Ryuuji took a chance to kiss her suppressing the moans she was making. God the boys loved how vocal she was.

A few more minutes went by and y/n pushed the boys apart to take a breath. She panting lightly but the boys weren't ones to slow down. She jumped slightly when Ryuuji's hands went to unbutton her shirt. Rin's hand traveled up her skirt and he placed his palm flat across her core. "Ah!" She moaned when Ryuuji pinched one of her nipples. "Oh? I guess you're sensitive there too." Rin chuckled. She was completely debauched when Rin pushed a finger into her.

She leaned against Rin and Ryuuji kissed the back of her neck. She pants against Rin the more he pumps into her. "Do you think a female demon can take two at once?" The male demon asked. "Yeah." She replied lightly as he slowed down.

"Bon, you can go first," Rin spoke and the mohawked male nodded. The demon removed his fingers and was soon replaced with Ryuuji's cock. "Ah!" She gasped against Rin and let out a small whine. Ryuuji held still and let Rin work her open a little more so she could also fit him.

Y/n wrapped her tail around Ryuuji's wrist and tightened when her fangs slip out. "Oh, that's new," Rin spoke and tilted her head up with his free hand. A whiner slipped and Rin decided it was a good time to push in next to Ryuuji.

Drool slipped from her mouth and she placed her fangs against Rin's shoulder. She didn't pierce him, just let them rest there as the two thrusts into her at a slow pace. "I think her mind is a little broken," Ryuuji spoke as her eyes looked a little clouded. "Probably overstimulation." Little whines and moans spilled from Y/n's mouth.

"Really close." She mumbled. Ryuuji pulled her up against himself as she got closer. "Can I come please?" She whined. "Yeah, you can." Ryuuji spoke.

She came with short pants and a whine. "Teeth. Hurt." She mutters and leans forward back to Rin's neck only for her to bite him. A gasp left from her which only fueled him to come. Ryuuji came not too long after Rin, filling Y/n as blood was being drained from Rin slowly.

"Alright. That's enough. You can't drain him." Ryuuji pulled her mouth away from Rin's neck and placed his finger in her mouth to nibble on.

Rin finally gained back some sense and pulled out slowly with Ryuuji. "I'll go get stuff to clean up." The demon spoke and stood up quickly and pulled up his pants.

Ryuuji made sure to keep Y/n up long enough for them to clean her up before placing her into bed. The two finished cleaning up the room quietly. "Maybe we went a little too hard on her," Rin admitted as they left the room. "She'll be fine. She might yell at us in the morning though."
