Cannot believe I started this for kinktober of last year and am only just getting around to finishing it, especially since all I had left before the month ended was minor corrections and formatting! Ugh! I am so desperately trying to commit to the various works already clogging my drafts, but it seems for each one I finally complete, another four appear! Unfortunately, these hyperfixations have a mind of their own; I’m just along for the ride, chasing the dopamine like a starved scavenger.
I hope to at some point make variations of this prompt for all the staff, but we’ll see where the dopamine takes me.
Sirris had never bothered to hide his fondness for you, singling you out in class to hear your voice and excusing tardies to keep you out of detention (none of the teachers much appreciated Leighton, so this was at least not expressly unusual). Perhaps the most incriminating evidence was his markedly bright smile whenever you were mentioned. What could he say? He found you to be pleasant company. Most charming was your inquisitive nature, always eager to learn.
Of all his students, he paid express attention to you, bewitched by the smallest of gestures. This was particularly true during the educational tapes he played. He obsessively tracked your tongue each time it darted out to wet your lips. The slight tremble of your thighs as you pressed them tightly together certainly didn't go unnoticed either. Perhaps you would have noticed the attention had you not been as transfixed by the bodies on the screen (one of which you found oddly familiar) as he was by you.
Lately, he found his thoughts more perverse than usual. Film sessions left him dissatisfied; none of his usual hookups could satisfy the growing desire. What had begun as a simple crush had turned into an infatuation—an insatiable appetite as necessary to fulfill as food or water.
Your curiosity and naivety were quite endearing. As a firm believer in tactile education, he longed to instruct you personally. He was confident that the chance would present itself; it was inevitable that you would have questions that only a reliable adult could provide answers to.
Your relationship with his son, however, proved troubling. Though he was relieved that the boy was finally loosening up, he could never have anticipated falling in love with his son's best friend. He desperately hoped that your relationship would remain platonic. You were such a wonderful influence, but Sirris knew his son could never satisfy you the way he could. You needed someone more mature and experienced to guide you.
Still, he could be patient. There was no need to rush. Even though you may be smitten with his son for now, it was only a matter of time before you realized the better option was only a stone's throw away. Just knowing it was his amateur sex tapes that made you squirm in your seat assured him of that.
An opportunity arose sooner than he’d thought.
"Dad, would it be alright if I invited my friend over for dinner? I’m a little worried they’re not getting enough to eat."
"While I've no issue with that, the shop closes rather late, and I would hate to keep them too long past dark, so why not make it a sleepover?" None the wiser to his father's twisted affections, Sydney happily agreed, seeing the logic in his suggestion.
Knowing he'd soon have you under his roof, Sirris felt a flutter of anticipation.
As the evening unfolded, Sirris played the role of courteous host, but his gaze betrayed him, straying towards your every move.
Having clumsily spilled sauce down the front of your shirt, you were sent to change into fresh garments—a lace nightgown and marching panties from the shop that had “accidentally” made their way home with him. You readily believed him, little naive thing that you were. You didn’t have to know that he had deliberately taken the garment home, the simple yet lovely sleepwear reminding him of you.
Sirris found himself restless. He wrestled with his morals for a brief while before finally deciding he was already in too deep to care.
He crept to the laundry room, shuffling through your dirtied garments set aside to be washed and dried in the morning, before locating his prize—a pair of simple yet adorable underwear. His fingers trembled as he brought the garment to his nose, raggedly whispering your name under his breath.
The scent of you filled his senses as he retreated to his room, where he surrendered to his pent-up desire, moaning softly into the fabric. He rushed to sit on the edge of his bed, neglecting to shut the door fully.
Working his strained cock out of his boxers, his thoughts drifted to hours previous; clothed in the delicate, lace nightgown, you looked as beautiful in it as he’d thought you might when he brought it home.
Your skin had glistened with the leftover dew from the shower, damp hair clinging to your neck. Those delicate lips had thanked him for his hospitality, even promising to return the favor at some point. The sight had been picturesque, almost revealing his sinister thoughts, were it not for the baggy bottoms he had slipped into shortly after returning home.
Tightly fisting his cock with the garment wrapped around it, his eyes fluttered closed, and his soft moans echoed in the darkness. Too caught up in pleasure, he didn’t notice the soft footsteps making their way down the hall, pausing at the door to peer in. He missed the eyes locked on his slender fingers pumping his exposed cock. If he had been paying attention, he would have noticed the labored breathing as you caressed yourself, equally eager.
"Ah…Damn…"
With a shuddered breath, he spilled into the garment, hips jerking erratically into his hand. While he rode out his orgasm, you gathered yourself together and quickly shuffled back to the guest room.
Bringing the soiled undergarment to his face, he shamelessly relished the combined taste of you and him before tossing it back into the basket.
Having had a taste, Sirris realized he couldn’t wait for much longer. You were the crucial component Sirris needed to complete his family. You needed him too, even if you hadn’t realized it yet.
