My stepsisters are sexy demons, and I must protect them

That evening, as a reward for his victory, Lilvyra decides to give Cassian a very special gift. Stripped of his clothes, Cassian now lies on his back on the bed in his room, while Lilvyra, completely naked in her human form, is on top of him. The girl's ample breasts press against Cassian's erection, massaging it with a slow, sensual rhythm. With the tip of her tongue, Lilvyra teases his glans.

Cassian grips the sheets tightly, lost in that whirlpool of pleasure, yet something inside him feels missing. There's a void that torments him, an inexplicable absence in that seemingly perfect moment. Then, suddenly, he realizes what it is.

«L-Lilvyra...» he gasps, his voice trembling. The girl pauses for a moment, waiting for his words. «C-Could you... be yourself?»

Lilvyra stares at him, surprised by that request. «Myself?» she repeats, amused and intrigued, since Cassian has always feared her demonic form, far preferring her human appearance.

Cassian lowers his gaze for a moment, his cheeks burning with embarrassment. «Because I'm in love with you, Lilvyra, not with the human shell you use to hide among us...» he whispers at last, almost ashamed of his feelings.

Lilvyra watches him silently, taken aback by his words. Then, slowly, her body begins to change. Her curves grow fuller, her skin darkens into a shade between gray and violet, while black wings and goat-like horns emerge from her body. Her gaze grows deeper and darker, and her voice takes on a demonic tone as she looks at him. «Cassian...» she murmurs coldly. «You know those feelings can never be returned. I am a being born from the magic of Nyratalir. As I told you before, everything I do follows the purpose for which I was created, not affection or love.»

Cassian shakes his head with a sad smile. «I know, but I don't care. I lost my father when I was still a child, and I never even met my mother. Everyone I've known only looked down on me because of the name I carry — a name I'm proud of. I've never known what it means to give or receive love, and my appearance never helped me fit in...» He pauses, his eyes glistening. «That's why I'm grateful you became part of my life, Lilvyra. Everything you've done for me — protecting me, helping me, staying by my side — to a human's eyes, those things mean love.» The boy exhales, summoning the courage to go on. «My feelings for you are simply the natural consequence of all that. You've shown me more care and attention than anyone else ever has. And to me, that's what love means. That's why I love you, Lilvyra. Even if you can never love me back...»

Lilvyra gazes at him in silence, but continues to use her breasts to stroke his hard length with a tenderness that contrasts with her demonic nature. His hands slide over her wings, caressing them with trembling fingers as she meets his gaze with her deep, black eyes. Cassian can't hold back any longer. With a long moan, his body trembles in a wave of pleasure as his seed spills across Lilvyra's face, which she licks clean with her long tongue.

Cassian lets out a deep sigh of relief. He runs a hand through Lilvyra's thick pink hair, tracing her long black horns. The demon lowers her face to his, lying on his chest. Her majestic black wings wrap around him like a dark blanket, and her sharp nails trail down his back, sending shivers that blend pleasure and calm. Cassian closes his eyes, surrendering to the moment, as his head rests gently on her chest, using her breasts as his pillow before finally falling asleep, exhausted, in her arms.

Lilvyra, being a demon born from the dark magic of Nyratalir, has no need to eat or drink, except for Thalukvar blood. In fact, human food deeply disgusts her. Still, she forces herself to eat just enough not to raise suspicion.

It's noon, and the final stages of the exams will take place in the afternoon. Following Lilvyra's advice, Cassian is eating more than usual to build up strength for the decisive match.

The attention in the dining hall suddenly shifts to them when Eiric Serenvalir approaches, looking down on Cassian with arrogance and disdain. «A cockroach like you could never have beaten Edward Rhaenor!» Without waiting for a reply, he sits across from Cassian. «They ran an investigation after your match, you know? Yet they found nothing suspicious. As if you could actually manipulate spells that advanced. Don't make me laugh!»

Eiric stands up with a sneer. «I'm certain there's something behind this, and even Professor Gorakthal agrees with me. It must be some kind of dark spell tied to that cult of brainless fools your father belonged to. If you have even a shred of dignity left, admit your deceit and withdraw!»

Lilvyra and Cassian exchange a quick glance, then, without showing any emotion, Cassian meets Eiric's eyes. «All this fuss just because you're afraid to face me? I didn't think you'd be such a coward, Eiric,» he replies coldly.

Cassian's words cut through Eiric like a sharp blade. Enraged, he slams both fists against the table, the sound echoing through the dining hall like a sudden thunderclap. The chatter stops instantly as the other students watch in fear. «Don't you ever call me by name again, outcast!» Eiric roars, his face twisted with fury. «My intention, had we faced each other, was to finish the fight quickly. A wretch like you isn't worth the time it would take to crush you — but I've changed my mind.»

Cassian's gaze stays fixed on him, impassive, almost indifferent to the rage before him.

«It will be a slow and painful agony. I swear I'll make you suffer more than you ever have! When I'm done with you, even the strongest Healing Magic will need months to put you back on your feet. That's a promise!»

♡♡♡

The final stage of the exams starts in the early afternoon and, as most had predicted, both Eiric and Cassian win their respective matches without much difficulty, reaching the final. The crowd is ecstatic. From the cheers and roars that fill the arena, it's clear that the vast majority of the audience supports Eiric.

«And after two days of extraordinary duels, we've finally reached the last match of this incredible semester tournament of the prestigious Sereltha Magic Academy! The final battle will be between... Eiric Serenvalir!» An ovation erupts from the stands at the mention of his name. «...and Cassian Thalukvar!» the announcer concludes, his tone more hesitant.

The two contenders enter, greeted in entirely opposite ways. Eiric, the prodigy from a noble and respected family, walks with his head held high and full of confidence, showered with applause and praise, while Cassian, his cold and distant eyes fixed ahead, inspires fear and distrust as the son of a follower of the dreaded cult of Nyratalir. The public execution of his father, Balthor Thalukvar, had shaken the entire continent, and that name still evokes terror. For many, the boy shouldn't even be there; to them, the Thalukvar name alone is enough to condemn him. Even the announcer himself seems to struggle to pronounce it.

At last, the most anticipated duel begins.
