It's your mother.

"Edward, how could you?!" a familiar voice rings out, full of hurt.

"You invited your cousin to the palace, and didn't think to invite me into your bed alongside her?!" Akkhadia smirks.

Taking a step forward, your mother swings the door shut behind her, then drops her glamour, baring her true demonic form.

She sheds her gown as quickly as she did Marissa Loon's skin, then pounces onto the bed with you and Corinne.

"Princess Akkhadia!" Corinne cries out. She doesn't cease in her movements astride your prick, but she does slow her pace a touch. "It's... an honour."

“An... honour?” Akkhadia scoffs. “And will it still be an honour after I've made you stick your tongue up my arse, dear niece?”

“That would only increase my delight, surely.” Corinne answers honestly, gazing rapturously at your mother's frame in all it's naked, inhuman glory.

“Arvha brought you up right, girl.” Akkhadia says, reaching over to caress the Morlandian's torso. The Spider simply bows her head in response.

“You've taken a liking to her, haven't you Edward?” Akkhadia says, savouring the whole situation. “Tell me, are you going to put a baby in her belly, as you did your aunts?”

“News... travels fast, it seems.” you pant, steadying yourself on Corinne's toned, pale thigh.

“Arvha, 'Zori and I have our own methods of communication, just as you and your cousins do.” Akkhadia responds. “I knew it would only be a matter of time before you brought children into this world, extended your grandfather's bloodline, but this... I'm proud of you, son.”

“Now, the time for words has passed.” Akkhadia says imperiously. “Now, we celebrate our victories, past and future as our kind best can.”

Your mother follows up her little pronouncement by pulling Corinne off you. Your body aches for the warm embrace of your cousin's petals, until you see what Akkhadia has in mind for her.

Turning her back to you (and giving you ample time to drink in the alluring sight of her naked form, her back, her tale, her fuckable purple arse), Akkhadia reaches back and seizes Corinne, guiding the part-human woman's face to her backside.

It would seem your mother's little barb before hadn't been meant entirely in jest. Akkhadia holds your cousin's mouth to her arsehole, encouraging the assassin to worship her with her tongue.

You yourself had paid homage to your mother in just such a way once or twice before, but now you watched on intently as Corinne did the same.

Akkhadia flicks her tail over The Spider's shoulder, her purple-hued, barbed appendage intertwining with Corinne's fleshy, more vestigial appendage, almost as if they're holding hands.

“What are you waiting for, child, join in!” Akkhadia urges you. As she speaks, your eyes do drift down to Corinne's supine and ready back haunches, a most tempting target.

Coming up behind your cousin, you re-enter her cunny, this time with an even more desirable view laid out before you.

Wanting for even more stimulation than she's already receiving, Akkhadia reaches down, begins toying with her cunt.

You start fucking The Spider harder, eliciting gasps of delight from her, straight into your mother's arse, the pleasure emanating from your body, through Corinne and into Akkhadia, like ripples in a pond.

You stare down at the two womens' tails, looped around one another like a braid.

“Fuck her harder, Edward!” Akkhadia cries out. “I want to feel this bitch squeal!”

You're happy to oblige. Steadying yourself on Corinne, you build up to a decent pace, pounding her soft, wet twat with eagerness and a relentless vigour. Corinne, being as depraved as she is, actually seems to enjoy herself more the rougher you treat her.

The three of you continue on like that, for several more minutes, before Akkhadia changes position. The demoness spins around, directing Corinne to instead worship her cunt, while she lays back, watching you take your cousin from the other side of the bed.

Corinne is only too happy to oblige, the fearless, deadly assassin as meek and compliant as a pliable serving wench once Akkhadia walked in on your little tryst.

You lock eyes with your mother. She stares back at you, lust and warmth glinting in her evil red eyes.

“What a son I have!” Akkhadia smirks. “I love that you are unashamed of your appetites, that you embrace them so liberally! This is what makes our bloodline so... so...”

It would seem that Corinne's diligent work is actually beginning to have an effect. Akkhadia writhes beneath her niece's tongue, overwhelmed by pleasure. The sight, as well as your mother's whorish encouragement, is enough to hasten you on your way yourself.

Pulling out of Corinne, you paint the demonic hybrid's skin even whiter with your seed, as your mother grips her face, grinding her sex wildly against The Spider's mouth as she climaxes.

-

Several hours later, you lie on your back, exhausted, Akkhadia clinging to you from one side, Corinne on the other.

“See, Edward?” your mother giggles. “The sheer fucking joy that family can bring. I'm so glad you agreed to meet your grandfather.”

Beyond the satisfaction “Marissa” professes, you do sense the reality that, had you been less embracing of your demonic heritage, your mother would've been likely to do something drastic to prevent you from spilling the cult's secrets.

“I'm glad too, mother.” you haltingly admit. “To think I might've missed out on ever meeting Corinne, here.”

You pull the naked noblewoman closer with your good hand. She smiles wildly, bringing her lips once more to yours. You taste your mother on them, and it only makes you reciprocate her affections that much harder.

You lay with your mother and cousin contentedly for a spell. You sensed Akkhadia was raring to go as ever, being an inhuman being that thrived on carnal delights. But on the other hand, your time with Corinne was likely to draw to a close soon. Dawn was only an hour or two off, by your estimation. Chances are The Spider would have to scuttle away, to rendezvous with her own mother very soon.
