A short ten minutes later, Akeno was still pleasuring me, or well, I guess it was more like I was pleasuring myself. On top of Rias' desk, her papers were removed, tossed to the side temporarily so that Akeno could lay on top of it, face up and tits spilling out to either side of her. Her legs were bent, but open wide, showcasing her twitching pink pussy and ass hole. That was the natural posture she took on, despite the fact that I was not on that side. Instead, I was where her top half was. Her head drooped just below the edge of the desk. I changed my mind about her. This girl was a complete and utter sex fiend.

Gawk!...Gawk!...SHLURP!

I rammed my cock right into her open mouth, the desk being the perfect height to use her mouth as an onahole. Her head constantly hit the edge of the desk, but clearly, the pain was being converted into pleasure far before she could take notice. Instead, she inflicted more punishment on herself, tightening her hands around her throat in order to make it tighter around my penis every time it slammed deep inside. My pelvis bone hit her face every time, inflicting more of the pain she was begging for. Her eyes rolled up until I could barely see the violet of her irises. Even still she was determined, not to let so much as a millimeter of precum escape her mouth.

"You ready? I hear Rias finishing up, if you can swallow all of this I'll reward you!" I was having fun, hips going wild as her soft lips remained tightly around my girth. She couldn't audibly say yes, but she made sure her frantic hums couldn't be misinterpreted. With one final thrust, my cock re-entered her throat, pouring my cum ceaselessly down it.

There was a struggle, but she pulled through all the same. "I-I did it, I did it master~!" She announced, opening her mouth wide with assistance from her fingers.

At the same time, Rias walked out of the shower. She had nothing but a towel over her head to dry her hair. "How was she?" She asked, amused by my use of her desk.

"I couldn't ask for a better onahole," I admitted, petting Akeno on her cheeks and watching as she gleamed at me deliriously.

"Great, I'm glad she was at least able to hold you over. Now though, it's time for the main course." Rias smirked, grabbing my naked cock with a familiar dexterity and leaning into me. She licked my naked chest and looked deep into my eyes with lustful desire, her breast, and hard nipples pressing against my stomach. "I haven't gone this long without your cock in me for a year."

I kissed her, wrapping my tongue passionately with hers. "Just give me a few seconds," I said, breaking this kiss off and going to the other side of Akeno, where her legs were spread and her pussy was bubbling with her fluid.

"I promised I'd reward her if she was a good girl," I smirked, running a finger along the girl's inner thigh and causing her to twitch uncontrollably, trying to trap my hand.

"I see, you really have made a cum slut of the girl in this short of time." Rias shook her head in mock exasperation. She circled her desk, going over to Akeno and smiling. "You hear that? You'll have to tell poor Issei that you've given yourself to Akito, he'll throw a fit for sure."

Akeno gasped from my teasing and responded to Rias. "H-he has Asia." She seemed to want to get this talk over with if the way her legs twitched was any indication.

Spoiler

"I suppose so." Rias giggled, "though I doubt that will quell him." She teased her Queen's nipple, pressing it and making the girl mewl.

"I-I don't care. Master~ please~!" Akeno begged, her hips moving without her control at this point. Rias looked surprised but said nothing else. She assisted me in giving out Akeno's reward as she activated her own skill on the girl's nipples. Meanwhile, my fingers fell down to her quivering cunt and in but a second I was 2 fingers deep in her depths.

The outcome was immediate. I rushed it honestly, but better pleasure would have to wait until she earned it. I scraped at where I knew her weak spots were, and after every 5th scraping of her walls, she clenched hard around me, body unused to the intense pleasure as she came over and over. I let this go on for thirty seconds, giving a proper reward and showing her just what was in store for her later on.

Pop

I brought my finger out of her honey pot, leaving her legs to droop unresponsively over her desk. She didn't say anything, much too lost to even fully comprehend what was happening.

Despite that, Rias cupped her by the chin and made her look at her. "Hurry and clean up, and then come to my room, you'll have new sleeping arrangements from here on."

Me and Rias retreated back to her room. The sex was nowhere near as intense as we would've liked. The walls were just that thin. Still, seeing how Akeno walked in to see me fucking her while holding her mid-air was a treat that really got us going.

We put a show on for the girl for a bit and then calmed down when we were getting a bit too loud. That night, I lay sandwiched between Akeno and Rias. Their soft breast pressed deeply into both sides of my head. It was a good thing air had become less of a necessity because I would rather die than move.

(3rd person POV)

Issei walked along the halls of Kuoh Academy. His head was down, and he moved with no sense of urgency as he roamed aimlessly. He indeed had class, but with how hectic his mind was at the moment, he might as well have not been there at all. It had been a day since Akito Nemura, the supposed new lover of his King had just showed up out of nowhere. And also a day since his dreams and conviction had all plummeted to Hell.

Yesterday, it had been Rias' demand that he stop perving on her. That alone had shot him to his core. After all, over the few weeks he had been a devil, he had grown to think that his perverted delusions may actually come to fruition. He had actually been making strives to become the ultimate harem king! And then, what Rias said had meant that he'd have to put a big slash right through the name at the top of his subconscious list. He hadn't realized until then that in the back of his mind, he secretly hoped he'd end up with her. It hurt, more even then when he had learned about Riser, and when he had realized he wasn't going to be able to win her freedom for her. At least then, he knew that she absolutely wanted nothing to do with the man, and that meant he might still have a chance to save her and steal her away.

Now though, there was nothing to save her from. She had openly said she loved the guy, there wasn't any way he could twist that in his favor. He had to give up on her. That alone had kept him up all night, even as Asia did her best to comfort him.

Then, right when he thought things couldn't get any worse. Before first period, Akeno had found him and pulled him to the side.

She explained a promise she had made with Rias when they were younger. That when Rias breaks away from Riser and finds someone she truly loves, Akeno marries that man as well.

"What?!" His outburst was loud. "That's stupid! Rias would never make you go through with that!" He gritted his teeth, right hand clenching his shirt as he stood face to face with the girl.

"Of course she wouldn't." Despite his clear frustration, Akeno replied to him with a soft giggle. "Rias would never make me do something I didn't want to, you know that."

"Then why?!" He grabbed his head, confused and disoriented beyond measure.

"Isn't that obvious Issei? It's because I want to be with him." Her words only served to make him more confused.

"Wh-how-." He held his head, suddenly feeling a big headache. "You don't even-… It's been a DAY!" He decided, finding that he was screaming more at her than he was for her.

Akeno's permanent smile twitched. "Sometimes a day is all you need, plus, if Rias has fallen as deep as she has for him, then I know he'll treat me right." She lacked the teasing tone she usually held.

He went silent for a while, face to the ground. "…Don't you think that's just a little too convenient? I mean, you saw what happened to Grayfia when he used that weird power right? What's to say he didn't do the same thing to the President?" His voice was low, but Akeno heard it clearly.

Just as soon as he finished he felt a shiver run up his spine. He looked up, shaking as Akeno looked down at him with cold eyes. "Issei", he had never felt her sound so cold, not even when they were up against Riser. "A devil you may be, but envy is not a sin that looks good on you." He found himself shut into complete silence. His gaze was forced downward and guilt set in, only overshadowed by his newfound bitterness. She thought to mention the Satans, about how they had seen plenty and would instantly recognize brainwashing, but did she feel he was worth the explanation at that moment? No.

The cold atmosphere died down and Akeno released a sigh. Her smile returned though with a noticeable level of falsehood to it. "Ara Issei, I knew you'd take it hard, but I didn't expect this." He refused to look up, not until he heard her footsteps slowly departing. "Now remember Issei, eyes up here, okay?" Akeno gave her final words and left him to himself.

A/N: Funnily enough, if Issei was the MC this would 100% look sus as hell.
