Serafall had apparently made plans on how to make this situation... The least awkward she was capable of, So while she went over how the recreated Key of Solomon would work within myself I was blindfolded.
Which for Sona and probably even Serafall for this being their first time actually having sex I didn't mind going in literally blind as Serafall blushingly explained how the ritual of binding would work. "So as you... Enter us with the Key of Solomon resting within your soul, the key will automatically create the template binding within our womb that will show as a pink glowing tattoo and this is where humans got the imagery from..." Serafall said with embarrassment clear in her voice as she spoke.
But she continued with her voice going to a barely audible squeak at the end. "And the binding will be complete when you reach completion and your semen acts as the soul-binding ink that signs the contract..."
Gods what a perverted tool... There was nothing that would stop me from literally binding anything with a hole and a soul. Lucifer was truly a terrible being as the binding was less of a contract and putting a powerful collar on that which I bound, absorbing their essence and talents while they also grew in power while sipping at my CYOA conceptual talents and perks. As was the norm with Lucifer and his pure evil, consent was an afterthought.
Hence why I was also being so accommodating with Sona and Serafall.
"Uhm Sona, how about you go first so you don't have to wait?" Serafall offered and Sona flinched and I could feel her movement as she was on my right sitting beside me in the large loveseat sleeper with my legs propped up as we had pulled out the legs of the bed.
I slowly reached over and as I felt Sona's arm, I trailed down with my eyes covered with the dense blindfold covering my eyes but not obscuring my magical senses as I could almost feel the shape of Sona's blue-tinged mana form within my mind as I took her hand into my own. "Sona, come here please," I whispered and I could feel Serafall on my left moving a bit as I gently took one of Sona's smooth and soft legs to help her sit upon my lap.
As Sona sat inside my lap I could feel she was utterly naked as my manhood slipped between her legs and she inhaled as the head of my length dragged across her lower lips as my hands closed in around Sona's waist.
"Serafall, I suggest you either hug Sona behind her to help set a nice pace... Or you can sit beside me and we can share this moment together," I spoke softly as I tried to envision what was happening beyond Serafall's blinding mana signature that was working up at how horny she was.
Serafall being the perverted goblin she was, actually hesitated at the options I presented. Watched her beloved sister from the front view as she lost her virginity, or be able to press her breasts against her sister's back as she helped to find a good rhythm and be able to fondle her sister at the same time...
Wordlessly I felt Serafall sit closer beside me with her larger breasts pushing into my arm as Sona audibly took a breath and then exhaled in a whine as my cock's head pressed into her tight womanhood and with an almost popping sensation I felt myself press through her hymen and her vaginal seemingly gushed as she just slipped until her delightful bubble shaped cheeks clapped against my thighs as she bottomed out on my cock with her groaning at the filling situation.
Sona may not have had the tits that were the symbol of this universe... But her ass was a work of slappable art. And Serafall spoke with a gentle smile as Sona whined. "It's ok Sona, we Sitri's are... Gushing wet down there, our asses even self lubricate actually." She said with some humor in her voice as she continued. "Just be glad you aren't Ravel Phenex... She is going to give that poor suitor bad burns on whoever dares to take her virginity."
Disregarding the thought of Ravel's cooch bleeding lava on my dick, Sona was literally gushing feminine fluids so our joining was unbelievably smooth with Sona apparently not even feeling any pain beyond the initial tearing sensation of her hymen getting broken.
So while Sona experimentally rose up and down upon my cock with her plush ass bouncing and clapping with BOTH the collision with my thighs and as she rose and those delightful cheeks clapped against themselves, I explored Sona's nubile form, the strong curve of her flared out waistline leading to her delightful ass and of course my hands rose to cup and massage Sona's breasts.
Sure she didn't have the E Cup and higher-sized breasts Rias, Akeno, and other titty monsters had, but she had a pair of very respectable C cup breasts that fit well into my hands to play with.
And Sona was either a sensitive girl on a hair trigger or she found this situation of fucking for power and keeping me close hot as hell as we only fucked with me helping her bounce into my lap for like five minutes before she bottomed out onto my cock and I felt her soft breasts pushed into my face as she hugged my head into her chest as she moaned out loudly as she reached her first peak with her cunt strangling my cock.
"Come on Jake, you gotta cum into Sona," Serafall whispered into my ear making me shiver as she clearly was wanting to speed this up as Serafall moved behind me so her breasts were pushing against my back and I grunted as Serafall began nibbling at my earlobe as she uses her hands to lift her sister up a bit then slam her back down on my waist making both of us moan.
"Yeah, cum your sticky human seed into my noble sister's pussy and ruin her for any devil heirs." She hissed into my ear and I couldn't help but have my cock twitch as well as shudder at the depravity Serafall was whispering into our ears as she literally her beyond human strength to bounce her sister in my lap quickly and without mercy, clearly just using her sisters cunt to milk my seed into her depths.
No longer was Sona's clapping ass a rhythm in which we fucked to. Now it was a beat to a particular fast techno song as Serafall seemed to delight in Sona's screams of pleasure and as Sona hugged my head into her tits with her small nipples being sucked into my mouth I finally reached my peak and I came harder than ever as I felt Serafall bit into my earlobe and Sona screeched out as it literally almost felt like I had stuck my cock into a garden hose with how hard her pussy gushed that it splurted its feminine fluids around my cock that plugged up her love tunnel.
I shakily lifted up my hand to my face and before I could remove my blindfold I felt Serafall kiss my cheek and the blindfold fell off my face as she untied it from the back, allowing me to see the lewd destroyed mess that was Sona Sitri.
A prominent glowing purple womb tattoo that looked like a heart with an arrow through it and a large tree growing around the tree was glowing aptly where her womb was. And as I looked up at Sona, a body I saw on her pale body was the small love bites I left as I sucked and bit her breasts and her face... Sona's expressions could only be seen as depravity taken too far as her eyes had rolled up with her mouth slightly open in her aheago'd state.
With Sona clearly incapacitated, I glanced over at Serafall, but I saw she had only eyes on the leaking cunt of her sister which was dripping with her excessive fluids that were tinged with the white of my cum. "Serafall," I whispered and she flinched and flushed but before she could say anything I whispered to her. "While you eat her out I will fuck you from behind and you can imagine its Sona with a strap-on?" I offered with a wag of my eyebrows and Serafall literally shuddered I thought she came a little at the thought but she leaned forward and kissed me on the lips before she retreated with a sweet smile.
"I will take your offer but I will do my best to only moan your name, Jake." She whispered winking as she went to sit in front of me as I got onto my knees and as her heart-shaped ass pointed at me I saw Sona's eyes widen as she seemingly came to life as Serafall audibly and messily began slurping like a fucking vacuum cleaner on her poor abused pussy.
