Whispers of Betrayal: A Succubus's Game

[Perseus POV]

I enter the classroom, finding my way to my desk, contemplating how dull the day might turn out to be. Enid and Olivia make their entrance, and my attention is drawn to their approach.

Perhaps today won't be as mundane; I watch with amusement as Olivia settles down beside me. Enid, on the other hand, seems to be battling nerves, evident in the noticeable blush that colors her cheeks. I watch with interest as she stumbles over her words, attempting a greeting, "H-hi Percy," she stammers, and her eyes avoid direct contact with mine.

Intrigued by her sudden shyness, I raise an eyebrow and inquire, "Hey Enid, everything alright?". However, she seems to ignore my question.

Then comes an unexpected twist. Enid, still blushing, fidgets with a strand of her hair and manages to blurt out, "I wanted to ask if you want to go on a date... NO, wait! Interview! Can I-I interview you?" The proposal catches me off guard, and I find myself watching her with a mix of surprise and amusement.

Enid's blush deepens, and her gaze continues to evade mine, darting nervously around the room. Her fingers play nervously with a strand of her hair, and a shy smile tugs at the corners of her lips.

While I continue watching her teasingly, I feel a delicate hand on my thighs that slowly goes up and touches my cock through my pants. I watch Olivia who seems to ignore her action and smiles mischievous at me. "Stop teasing her." After saying that she grabs my penis with the fabric of my pants and rubs it harder, expecting a reaction. Playfully observing her, my mind reflects on the events of yesterday. In response to that incident, I spent the entire night awake, determined to devise a skill to address such situations. The outcome is a watered-down Occlumency Spell. This newfound ability allows me to maintain a clear mind and still embrace the usual joys and challenges of adolescence. "Sure, what about tomorrow?"

Her excitement bubbles over as she eagerly responds, "Yeah, can we do it in Jericho? I heard there's a nice coffee shop with excellent drinks!"

"Sure," I agree, and her enthusiasm intensifies. She jumps with excitement, letting out a shrill, "Yess! I-I mean sure, see you tomorrow," before hastily storming away from the classroom, her face adorned with a heavy blush.

Naturally, I discern that the interview is merely a facade; even a blind person could see that there's more to it. The lingering question is, who or what gave her the courage to propose it? My gaze shifts to Olivia, and I sense that she played a role in instigating this situation.

"Wanted revenge from yesterday and make a mess out of me in front of Enid?"

She watches me with annoyance visible in her eyes and says, "Yesterday I persuaded Enid to share you with me and to seduce you during the interview."

"Why did you do it? I have high standards for woman".

"I know, but I saw how you look at her ass and thought you were interested in her. So, I convinced her to seduce you. If you don't want her, you can simply use her as a toy".

"Hmmm…how does it feel to betray and hand over your best friend to me?"

"If you like it, I don't mind…."

"Obedient girls must receive a reward, what do you desire?"

"I-I desire to please you."

"Even your reward is used to satisfy me, I am very happy with you. But you need to do more than just stroke my dick to please me."

She just grumps and casually unzipped my pants and began to rub me through my boxers which almost felt wet from the insane amount of precum that began to come out of me.

She got into more of a rhythm eventually pulling my whole cock out.

She gasps at his size and becomes beet red. The size isn't something extremely large like 50 cm or something, but it's still big for a boy and the thickness is the one what really stands out. She watches it with curiosity and a hint of blush and suddenly bents down and sniffs it "Hmmm, I like your scent". If it wasn't for my new spell I would have cummed just from her sniff.

The lessons begins and she takes note while giving me a handjob. It's a very strange feeling, being in class while a girl has her delicate hands wrapped around your dick and gives a handjob. Naturally I have used my space affinity to distort the space around us, I don't want to risk that someone sees it, she is only mine and only I can see such naughty things. The lesson goes on while she gives me a handjob and a short while later, I lean in and whisper to her "I am coming."

She understood and, with a casual demeanor, leaned over as if she dropped her pencil and she took my entire shot in her mouth. I cummed immediately when I felt her wet lips wrapping my dick and her tongue licking. She gulped it all and straighten up like nothing happened. 

I am right… she is a succubus disguised as a shy girl.

After class, I invited Olivia to join me, and together we made our way to the serene lake, finding a comfortable spot beneath the shade of a tree.

"I've been contemplating your words from yesterday and have chosen a reward," I conveyed as my hand discreetly slipped under her shirt, resting gently on her abdomen. The softness beneath my touch diverted my attention momentarily. Disregarding the distraction, I uttered an incantation, activating the Celestial Seal spell. A captivating tattoo materialized just above her abdomen, the magical insignia pulsating with a delicate light.

Olivia blushed in response to my actions and let out a gasp as she felt mana flowing into her body. Her eyes widened in amazement, "You marked me? Thank you! Now with this slave seal, you can trust me completely!"

Slave seal? How much anime did she watch? I block her "No, it's a Celestial Seal, a spell that not only protects but also strengthens you."

Curiously, she traced her fingers over the intricate design. "Oh… you still marked me and need to take responsibility!"

"Sure…"

She asked with curiosity, "How can it strengthen me?" I took a moment to explain, "It will fortify your body and mind, essentially eliminating impurities."

During my time with my grandma, I didn't only train like a maniac but also researched the limits of my spells and explored their potential. I immersed myself in unraveling the intricacies of how the magical multiplier operates. This exploration led me to question whether a similar concept applied to other creatures. After studying and conducting experiments, the findings proved to be fascinating.

Normies, individuals lacking innate magical abilities, possess a multiplier of 1 to 2, equivalent to a cell level of about Lv.1-Lv.2. This minimal multiplier primarily fortifies their physical bodies, given their absence of mana required for broader enhancements. In stark contrast, supernatural creatures revealed a different reality. Their multiplier spans from 3 to 9, indicating a diverse and potent spectrum of magical potential. Even the weakest among the outcasts could easily overpower a defenseless human.

During my experiments on animals at my grandmother's house, I made a groundbreaking discovery – the ability to spread their alpha-cells through the Celestial Seal. This newfound realization empowers me to fortify individuals, enhancing their strength, making them more robust and formidable, and probably also improving their talents.

After all these experiments, I formulated a simple plan: those I trust will be marked with my Celestial Seal, allowing me to aid them in spreading their alpha-cells throughout their entire body, making them stronger in the process. For my wifus, those who share an unbreakable bond with me, I will generously donate my alpha-cells. This infusion will elevate them to a multiplier of 20 or more, transforming them into immensely powerful beings.

For now, I will assist Olivia in spreading her alpha-cells. Without any secure bond, if she were to betray me, I hold the power to eliminate her, given that she isn't as strong as me.
