The bath was already steaming when I sat down on the stool. I knew this was coming, so I might as well enjoy it. I sit there with only a towel around my waist, while the girls are in a similar state with only a towel for modesty, which is a joke of a word in this situation.

"So, what's the rationale behind this one, Maria?" I ask.

"Spending time naked together is the perfect way to build trust, is it not?" she asks.

"I'm really not seeing this. I think that I'm going to get aroused by a cute loli succubus and a smoking hot redhead prancing around, wet and barely covered. That's going to trigger Mio, and she's going to trigger the curse, which will result in more erotic hanky panky."

"No, no, if you are both sharing in the embarrassment, then your unity will grow whether you like it or not."

"More like my unit will grow whether Mio likes it or not. And if you think this is embarrassing for me, you need to pay better attention."

"Now then," Maria says, ignoring me. "Mio-sama, shall we wash big brother's back?"

"I dunno, Maria? This is seriously Ecchi-Sketchy," I say with a resigned sigh.

"No!" she says, sounding a bit more desperate than convincing. "Allowing yourself to be vulnerable by exposing your back to us is how you'll actually be able to build trust! Now, Mio-sama!"

Mio jumps a little. She's obviously uncomfortable with this but is buying into Maria's line because she doesn't know how to deal with her emotions. She's an inexperienced teenager with an unsettled hormone profile and a shitload of highly volatile magical energy. I'm proud of her for having not leveled the city yet.

"Y-yeah... I get it," Mio says and steps away from the wall where she'd been standing. She comes close and kneels behind me, soaps up, and is ready to go. "I-I'm starting now."

She hesitates.

"You don't have to do this if you're uncomfortable, Mio. We can find another way," I say. I know she'll do it anyway, but I leave her an out, just in case. The plot has changed a few ways already, and I plan to change it a few more. I just have to figure out how to change it to get the optimal results. 'Optimal results' is code for a heavenly harem of happy horny honeys.

"Huh? N-no, it's nothing," she says and starts scrubbing. She's a little rough, but I chalk it up to nerves. As I said, she's inexperienced.

"Ahem. Ahem," Maria fake coughs, and Mio stops. Now for the good stuff. The slippery silken skin of Mio's breasts presses against my back, the nipples applying contrasting points of pressure. They really are wonderful. Her arms wrap around my body, and she pulls our bodies together.

"Oh?!" I say to the pleasant sensation.

"D-don't move!" Mio says with a panicky edge to her voice. "Please, stay still. If you move, I'll kill you a hundred times over."

"Alright, you can set the pace," I say.

Mio begins to rock back and forth, pushing her breasts up and down against my back, the soap providing a suitable lubricant, but there is enough friction to stimulate Mio's nipples into firm peaks. I don't know if she realizes what she's doing, but her soft moans every time she scrapes those nipples over my back tell me she's enjoying it, at least on a subconscious level.

"That feels really nice. Are you okay, though? You don't have to push yourself too far." I can feel her breath on my back. The way she's going, we're both going to need cold showers. I can just hear the jokes now, 'How do you know Issei is the son of Sapphire? Because his balls are always blue.'

"Ma- maybe a little break," Mio says, shuddering a little from overstimulation.

"I thought this might happen!" Maria says, opening the bathroom door. When the hell did she leave the room in the first place? "So I brought some of the cake you bought to have a little snack."

I shake my head. "I do like a moist cake, but bath steam isn't really what I was thinking, Maria."

Mio stands up and backs away, almost tripping on her towel. Maria crouches next to me with the cake and leans in a little far, 'slipping' and toppling over. I react and catch her, but the cake, as expected, bounces off my chest, arm, and hand, leaving a heavy amount of frosting in its wake. Oddly enough, Maria was relatively unscathed.

"Alright, maybe we should just clean this-" I say, anticipating the interruption.

"You must not!" Maria says, her voice a little husky. "You bought this cake for us. I-I want to enjoy it."

Again, the tone is different, but the words are similar. Maria leans in, her breathing slightly labored, and her little pink tongue comes out of her tiny mouth and runs down my frosting-covered arm. I was aroused before; now, I'm rock hard.

My breathing is labored now. I want to stack these two girls like cordwood and split them. How the fuck did Basara not snap. Oh yeah, he passed out and dreamed about doing something with the two. Well, fuck that noise. I'm here for the long haul.

Maria looks up at me with puppy eyes. "I-it would be rude... to the cake if I did not at least eat the portion that is not on the floor."

Her tongue flashes out once more and catches some cream on the back of my hand. Her eyes, having taken on a dreamy quality, stay locked on mine. "This is quite well made. Would you like some too, Mio-sama?"

I feel Mio struggling with her desire and look over. She's recovered her towel, but her servant mark is blazing pink. Is she jealous? The mark flares, and Mio moans, her body shudders, knees going weak, and she stumbles forward. Maria let go of my hand just as I turn to catch the falling girl, our towels the only thing between me and an accidental paizuri.

Mio stares at the frosting still on my chest and leans in to lick it off. I'm ready to lose it. If I relax even a little, I doubt I'd be able to hold back. 'Uh... Think... I need to take control of this situation... Wise Man, I want to make a skill to replicate the pleasure I'm feeling onto the person, or people causing the pleasure.'

[Reciprocal Ardor (C)

'Perfect. Create.'

[LP Remaining: 900]

""Mwaaa!"" the girls cry out at the sudden influx of pleasure, the shocking increase in pleasure causing them to orgasm, buying me enough time to get control of the situation and my libido.

I resituate Mio on the stool and look at Maria sitting on the tile, her breath harsh and animalistic, the towel slipping, ready to reveal the pale beauty hidden beneath. I lock eyes with Maria. "I'll deal with you in a moment. Stay. Put."

Maria blushes and nods. I kneel behind Mio and take hold of her shoulders. Then, leaning in my breath, as light as a butterfly, caressing up her neck to her ear. "Mio," I say, barely more than a whisper. "Everything you did, felt wonderful. So wonderful, in fact, that I want to reward you."

Mio chews her lip and looks to the side. "Y-you do? O-okay, onii-chan."

I smile. "I'm going to touch you now. Let me know if you feel uncomfortable, and I'll stop. Alright?"

Mio nods slowly. Just before I start, I throw the floor cake into my Pocket Dimension for easy disposal later. Mio is still a bit damp from the breast massage earlier, but she's rinsed off the soap. I lather some soap in my hands; it's not 'massage oil,' but it'll do.

I slide my hands over her back, up her neck, down her shoulders and arms. Next, I move around to stroke her feet and legs, pushing the limits a little by gliding my hand under the towel and up her thighs. I only hint at how far my hand could go. Teasing the possibility.

Once her heavy breathing calms, I skim my hands up the outside of her thighs, under her towel, and cup my fingers around her hips. Then, leaning my face in next to hers, I say, "Mio, I know the curse has been affecting you today. It's not good to be in that state for so long. If you would like, I will help you. You just have to ask, Mio."

I draw back until I'm eye to eye with her. She's already tired from fighting the curse and the stimulation up to this point, she won't last long, but she has to submit, or the curse will continue. Her eyes, half-dazed, try to focus on my face briefly. She swallows hard and licks her lips. "P-please... Help me, big brother?" she finally asks, her voice husky with arousal.

"How? You need to say it. How do you want me to help you, Mio?" I insist.

"M-my breasts. P-please, play with my breasts."

Maria speaks up. "You have to ask him right, Mio-sama."

Mio's breathing has gotten more haggard. "P-please, big brother. Please, play with my breasts."

I start slow, placing my hands on her waist and sliding them up to the underside of her gravity-defying tits. The underboob is surprisingly sensitive, and she shudders from just light grazing with my fingertips. In the back of my mind, a perverted thought wonders how these heavenly hooters compare to Rias Gremory's and what it would be like to get a double paizuri from the two girls. Throw in Akeno for the winning hat trick.

I change the game and grasp her breasts, squeezing the flesh, roughly molding them to my heart's content but taking care not to hurt her. The flesh of her breast is firm yet supple, an incredible feeling that leaves me wanting more, but this isn't about me right now. Every couple of rotations, I ease the pressure, and my thumbs circles the areola, brushing lightly against the nipple before starting the cycle over.

After a moment, when she started getting used to the pattern, I drop one arm to her waist and pull her onto my lap. If not for our towels, we'd have taken this to a whole new level. Our most intimate of intimates grind together, causing a sharp increase in Mio's moans. Her voice reaching a higher register, and she struggles to hold on.

She wraps her own arms around my neck, my hand at the small of her back slides up her spine to the back of her head, and seize a fist full of those crimson locks. Then, pulling her head forward, I time the moment our lips touch with a firm pinch and twist on her cherry peak. Mio's eyes go wild, and her gasp is muffled as I capture her lips.

I increase the pressure, building the tempo, kiss, lick, suck, knead, pinch, twist. Mio's body shakes as she grinds her hips against my cock; her clit pressing against the shaft, only one thin towel separating them now. Finally, I pull her away from my lips with my hand still clutching her hair and arch her back, raising her chest and the perfect pink nipple high enough to grasp between my lips and draw it into my mouth, where my tongue draws a long swipe across the tip.

Mio is incoherently babbling, her tongue hangs loose, and her eyes have glazed over. Maria's voice cuts through my own brain fog. "It's over, Issei, she fully submitted. We should let her rest."

Shit. I almost lost it there. I was so engrossed that I didn't even notice the room-brightening flash of pink. Thank god that Maria was here. That could have gotten out of hand and ruined all our work. I look up and see Maria behind Mio, holding her shoulders.

A wave of relief washes over me. "Thanks, Maria, your timing was perfect."

"Hmmm... It doesn't look like all of your body agrees with that sentiment."

I look down to where her gaze is locked, and the first thought I have is, 'Well, I am part-dragon.' I set Mio, with Maria supporting her back on the stool and readjust the towel. "That thing doesn't get a vote right now," I say.

"Too bad," she says with a smile, the little tease.

"We can discuss that once we clean up Mio and help her to bed. You hold her, and I'll get things ready. It'll take my mind off... everything."

It should have taken longer to dominate Mio, but there are extenuating circumstances. Poor Mio was being bombarded with heightened sexual pleasure from a combination of the succubus-based Testament, Min's Touch, Reciprocal Ardor, and her own inborn sensitivity. Of course, she's going to respond more quickly. This is a potential downside for the future, but I'll jump off that bridge when I get there. Besides, it's a good rationale for more threesomes since that would allow them time to recover between sessions while I am attending to the other.

Maria and I wipe down Mio, and I carry her to her room, where we get her into her pajamas and settled in bed. No dinner for us tonight, I guess. Maria and I exit Mio's room and gently close the door.

I let out a sigh and look over to Maria, who is smiling. "You look happy," I say.

"I am. Mio has been through a lot in a short amount of time. It's nice that she has someone to love and care for her," she says, but there is an undertone that I recognize.

"And what about you?" I ask.

"Hm?"

"You know," I say, looking away while leaning against the wall, my hands behind my head. "You haven't gotten your reward yet."

I see her cocking her head to the side, thinking. "Reward?"

"Well, yes. We've had to take care of Mio because she activated the curse, but you haven't yet. That means you've been a very good girl, doesn't it?" I ask. Maria's mouth opens in a silent oh. "And good girls should be rewarded."

Maria's eyes sparkle. "Well, you did promise me a kiss like you did Mio if I behaved, big brother," she says coquettishly, clutching the hem of her nightie. "I was a good girl. You said it yourself."

"So you want a kiss like one I gave to Mio to be your reward?" I say, my own eyes twinkling. "I kissed Mio in a few places; where would you like me to kiss you?"

Maria's pupils dilate, and her cheeks flush. Grabbing my hand, she drags me towards her bedroom.

An hour later, Maria is curled up against my chest, purring like a kitten, and I have a much better idea of what a glazed donut feels like. Maria had been feeling a little jealous and wanted to try everything that Mio had.

The finale was when I clutched the petite girl's buttocks, massaging the cheeks while brushing my thumb around the rim of her anus, all while using my tongue and mouth to enjoy the taste of her honeypot fully. Fun fact. Succubi, being all sex demons have love juices that taste like slightly sweet cream.

It was when I sucked on her clit while lightly pressing my thumb on the rosebud-like butthole that her strongest reaction happened. It's a good thing that Maria had put up a one-way sound-suppressing ward around the room because her scream rattled the windows.

It was a full-body, toe-curling, major squirting orgasm that seemed to last several minutes. The aftershocks lasted five minutes after that, and the dopey grin hasn't left yet. I lay there, a fine shiny coating on my face and chest stroking her silken silver hair.

Thinking about the plotline, I slowly lose my smile. I need to get ahead of this. "Maria," I say, my voice not the playful tone I'd been using.

She notices and looks up at me. "Hmm?"

"Can you get in touch with your mother and sister in the Demon Realm discretely?"

She pushes herself up to her elbows. "I think so. Why?"

"Attacking us directly would be difficult if they don't want interference from other factions, but if they had a way to force our compliance, like say, a hostage, it would be a lot easier to get to us. Mio only has us, and they're scared of my dad. You're the only one with a family that could be vulnerable."

Talk about a mood killer. I stroke her cheek and plant a light kiss on her lips. "I want to get ahead of any potential threats. We can't predict everything, but being prepared for something like this will reduce the likelihood that it will happen. You are important to me, and so is your family."

I pull her into a hug a go back to stroking her hair. "I have an idea to try to get us some more help."

"From the hero village?" she asks.

"Hmm... It's possible, but not what I'm thinking," I say, knowing Yuki will probably help us out in the end. "Don't worry. I have a plan. Or at least an idea that may become a plan."

"Hmm... It's more girls, isn't it?" she asks with an accusatory tone.

I smile. "You're not jealous, are you?"

"It's not me who you need to worry about," she says.

"Mio... I know she's not really ready to understand this, but whether it's just the three of us or a thousand of us, I will never abandon you two, and I will do everything in my power to keep safe and happy."

"Until death do us part?" she says with a snarky smile.

I lift her chin once more and gaze into her eyes. "If death thinks they can part us, they are in for a hell of a fight."

She snorts. "That was pretty cheesy," she says. I can't help but smile back at her. "Even more so with my cum all over your face."
