I guide her mouth around my cock for a few minutes and give some... gentle advice. "You have a tongue. Use it."

Now that I think about it, maybe Akeno would be a better match with my soon-to-be submissive black-winged canary. It would let her get some of her sadistic tendencies out and work through her issues with her fallen angel heritage. Now, that idea has merit.

I lift Raynare back off my cock; my fist still knotted in her hair, a trail of saliva on her chin. "This is taking too long. Your education is going to have to wait for our next meeting. For now, a crash course will have to do."

I guide her back over to the edge of the bed and lay her down on her back across the bed. Stepping around to the opposite side, I look down at her lovely face and draw a finger along her jawline. "I really wanted to go about this more gently, Yuuma, but I suppose that was just wishful thinking on my part. Maybe one day."

I drag her back until her head is off the edge of the bed and my cock is aligned with her mouth. I feign a sad smile. "Deep breath now, dear. You may not get another one for quite some time," I say and push my hips forward, breaching her lips with my shaft, pushing it all the way to the back of her mouth and beyond.

Her hands clutch at the sheets tearing them as her tongue and throat work to dislodge the obstruction that is my cock. Finally, after a moment, she manages to get control of herself and relax her throat a little. Apparently, angels don't have a gag reflex. Why am I not surprised?

I pull back to the transition point between mouth and throat and push forward again. Back and forth in a slow rhythm until she gets used to the pace. Her throat is tight around my glans, causing a soft pop when I pull back to her mouth.

"Let's kick it up a notch." I pull back and drive forward with a series of quick hard thrusts. Again, she spasms and moans, trying to readjust, and her tongue lashes along my shaft. "Oh, fuck, that's good. Keep doing that."

I can see the bulge in her throat where my cock stretches her with every thrust. The feeling of her throat working to clear the blockage and her tongue twisting around the shaft is driving me higher and higher. One of Raynare's hands caresses her breast while the other is buried, sloshing the juice in her dripping wet pussy.

Reciprocal Ardor is doing the heavy lifting here though, every thrust sends a wave of pleasure shooting through each of us, and with the boost from the curse and my Min's Touch, Raynare is almost constantly orgasming.

One more big one should do it, and it should hit when I finally cum, which is close. I can feel my own climax coming. Raynare is incoherently moaning, sending vibrations down my cock. "I'm... I'm almost there, Yuuma. Be a good girl now, Yuuma, and take it all. Don't spill any," I say through haggard breaths.

I let out one final groan and splash a coating all down her throat. I jerk, and as the tremors send further spurts, I feel that glorious release subsiding. The pink glow of the room begins to fade, and I smile. I slowly pull back until just the head remains in her mouth; her tongue works automatically, licking and sucking on the tip like a lollipop.

"Good girl," I say and pull the rest of the way out. She tries to follow it with her mouth reaching out with her tongue. Her hands come off her breast and out of her sopping wet hole to reach for me. I grab her wrists and hold on to them. "That's enough, Yuuma. If you behave, we'll do something special next time."

She calms down, and I help her sit up. "Think you can put away the wings now?" I ask. She nods, and her whole form shrinks down slightly, losing the wings in the process. I pick her up and resituate us on the bed to where she is resting curled against my body.

After a few minutes, her breathing has slowed to a normal rate, and she looks strangely calm. She has a hand on my chest. A little voice in my head that doesn't belong to a dragon thinks she might try to claw my heart out. I opt to ignore it for now.

"What did you mean when you said you didn't like the way my story ends?" she asks.

"Just what I said. Your ending was... disappointing. I wanted more than just a traumatic experience. It felt like a waste for you to die like that," I say. Honestly, she probably had more impact than she deserved, but I still wanted her, so here we are. I don't know why. Maybe, just because she's hot. I could be that shallow sometimes. Or maybe it's the Issei in me wanting to save his first girlfriend. All that I know is that I just throat fucked a fallen angel, and it won't be the last time.

"How do you know how I... end?" she asks, with the distinct sound of a gulp mixed in.

"Hmm... I'm going to try to keep this simple. This is not the only world. In fact, this is not the only world like this world," I say, though honestly, considering how this world seems to have been formed, maybe it is. "Some of the similar worlds aren't exactly the same. They have small differences between them, and I have an ability that can see some of those. In most worlds, you successfully kill me, but that's not where it usually ends. It is merely the catalyst of your own demise."

She looks confused, so I continue. "You have plans to steal the Sacred Gear from Asia Argento, killing her in the process, right?"

"H-How did you know about that?" she asks, looking up at me in shock.

I roll my eyes at her. "Think about what we are discussing here?" I say. "Anyway, I suggest- no, you will NOT be going forward with that plan. If you want power, I will help you, but certain things are off-limits. Asia Argento is one of them."

"Is Asia Argento related to my... end in one of these other worlds?"

"Indirectly. Asia, herself, wouldn't hurt a fly. You cause her death and are obliterated for it. Thankfully, that won't be happening now because you are going to obey me in this."

She's quiet for a minute. "You'll help me get more powerful?"

"Of course. If I just wanted a little fuck toy, there are easier ways to get one," I say, running my fingers through her hair. "I need allies. You may not know this about the Master-Servant Testament, but the more loyal you are and the closer we become, the more it reinforces our power and makes us greater than the sum of our parts."

She touches her neck, where the mark is hidden. "This isn't the only way I'll be helping you to get stronger. I have other methods as well, but you should rest now. Rewards come to those who perform good service. We're going to have a guest in a little while. I want you to stay in bed and stay quiet. I don't need a conflict starting for no damn reason. So, sleep if you can."

She actually snuggles into my side and closes her eyes. "Yes, master."

I don't if it's real or not, but that seems like a quick flip. I don't know, but I really can't wait to go back to being a snarky bastard instead of this bullshit 'master' act. It's exhausting. I hope I don't have to do this again.

"Master, please wake up... Master."

This sounds familiar. I reach out to shut off the alarm, but instead, my hand lands upon something soft and warm with fantastic pliability.

"Oh! Master!"

And it talks. I peel my eyelid back and blink away the sleep to a fantastic sight. A beautiful face, slightly pink from arousal, I assume, an elegant neck, and down a little farther, passed the shoulders to where my hand rests on a perfectly perky set of tits. I move my hand just a little roll the pert pink nipple between my thumb and forefinger. An adorable squeak follows my action and the pink in Yuuma's cheeks turns red.

"Master-r-r," she complains in horny frustration.

I smile. "Good morning, Yuuma."

She frowns a little, but it turns into a pout, and she points to something on my opposite side. "What is she still doing here?"

I turn my head to see a glorious head of cascading crimson hair and a and even more glorious set of tits. This world is like a theme park of impossibly gorgeous breasts and fan service. God bless Ecchi-World. Maybe they can have Shizuka as the mascot.

A few hours earlier, Raynare had fallen asleep, and I draped a sheet over her body. Next, I put my clothes back on and prepared for my guest, then placed summoning parchment on the desk in the room, and I sliced my finger enough to draw blood. Then, I anoint the parchment by dripping my blood on the seal until it activated.

I sat comfortably on the chair and waited for the guest of honor. The magical seal glowed Gremory red, expanded, and a beautiful young woman with blood-red hair and a body that most could only fantasize about materialized in front of me.

She appeared facing away from me, which gave me a lovely view of her ass and legs. "So it's you. The one who called me," she said

As she turned around to reveal one of the most memorable sets of ta-tas in all of ecchi, she appeared startled, as though this isn't what she was expecting. She probably was expecting a mostly dead body assuming that the fallen angel would have stabbed me by then. She blinked and looked a little confused.

"I am Rias Gremory. I am a devil..." she said. Her brow furrows slightly as if she wanted to say something else but forgot. It didn't last but a second, and she recovered quickly. "Nice to meet you, Toujou Issei-kun."

"The pleasure is all mine, Princess of Gremory," I said.

"To what do I owe the pleasure of your summons this evening?" she asked and then looking over to Raynare. "You don't mean for me to join you, do you?"

I smiled at that. "As pleasant as your company would undoubtedly be, I'd like to start our relationship off with... well, a relationship. An alliance, really."

One exquisite eyebrow raised. "And what benefits would we gain from an alliance?"

I turned up my hands in a slightly arrogant 'me' gesture. "Well, let's start off with the basics. Mutual aid. Your enemies are our enemies. We help each other when we are in need."

She chuckled at that. "Your enemies are rather formidable, while mine-"

"Are a politically motivated arranged marriage to an absolute twat and a few others that you are not aware of yet. I'm willing to help with all of those. The later problems are not something you can deal with on your own or even with Sona Sitri's help.'

That time both eyebrows climb. "You're very well informed. I was thinking about recruiting you to my peerage..."

"Yes, I noticed Koneko following me. I assume that's why you knew about Yuuma. I assume it has to do with this?" I said and hold out my left hand and the Boosted Gear forms.

"Sacred Gear, Twice Critical. So it's true. We weren't sure at first, but yes, we thought you might have one, and it was our initial interest, but after looking into your background, we were even more interested. Son of the War God."

"But, you were expecting the fallen angels to kill me and then come swooping in to resurrect me as a devil, right?" I said with a smirk. She frowns at that. "That's why you have someone give me this summoning parchment. Don't worry. I get it. Some half-trained hero against who knows how many fallen angels, but did you honestly expect my father to leave me half-trained?"

She grinned. "It was a longshot, but when the summons came through, I thought maybe you weren't as strong as we thought. It makes more sense now that I know you have a Twice Critical. It would double your already increased hero strength."

"Well, I'm sure it would, but you are wrong about one thing," I said and held up my left hand again. "This isn't a Twice Critical."

She frowns. "It's not?"

"Nope. It's the Boosted Gear." Rias's eyes go wide, and the word 'Longinus' is whispered under her breath.

"Are you sure you don't just want to join my peerage?"

I smile. "I honestly don't think it would work. My bloodline... is unique. So turning me into a low-tier devil wouldn't work."

"Hmm... I suppose not," she said with a pout. "So, how do you propose to help me with my problem then?"

"Well, as I see it, we just need to establish a connection between us strong enough to allow my group to interfere and be counted among your group when the trouble rears its creepy head."

"I suppose you have an idea?"

I smile.

"She's your what!?" Raynare shouts.

"Calm yourself. We wouldn't want the curse to kick in, now would we," I say calmly. Raynare's eyes widen in fear.

Rias, of course, rolls to her back, fully exposing her gorgeous body to us. Her eyes flutter open, and she looks between Raynare and me. She stretches her arms up over her head, arching her back, further accentuating her voluptuous chest.

She lets out a sound somewhere between a moan and a groan. "Good morning, sweetheart," she says to me with a teasing smile. Then she turns her eyes to Raynare with a much cooler look. "Servant."

Raynare glowered at Rias. "As I was saying, Rias is now my fiance. This cements our alliance and allows us to intervene on the other's behalf should a threat to either arise. Regardless of the nature of the threat. Who would dare say that a person's fiance can't be there to help and protect them after all."

"But-"

"It's under control, Yuuma. Trust your master," Rias says.

"W-Well, what am I supposed to do?" Raynare asks.

Rias gets up and reaches for her discarded undergarments. My eyes follow as she slips her panties on. For some reason, I always found her sexiest in the first few episodes. It's probably because she had an aloof and mysterious vibe then. After she's around Issei for a bit, she relaxes somewhat. Not that I wouldn't happily pin later seasons Rias to a bed and fuck her brains out, but initial meetings form a large part of your opinion on someone. I think I did well for our first.

"Master-r-r!" Raynare whines.

I place my hand on her head and stroke her hair gently. "I have things to take care of today, so why don't you go back to your place and keep an eye on their movements. Remember what I said about Asia. Don't test this order, Raynare. I would hate to lose you now that I have you."

"Hey..." Rias says, turning around and moving her hair to the side to expose her unclasped bra. "Will you fasten this for me?"

I smirk. My life just keeps getting more interesting. Mio is going to be so pissed.
