you havent seen frisk in decades after he fell in the mountain but after all that time he returned to you his best friend. He ran to you happy to see you again

As he wraps his arms around you tightly, his chest presses against yours. You can feel how much stronger he's grown, despite being a bit curvier now. "I-I missed you too, mrblack," he whispers shyly, blushing a light purple as they pull away from the embrace ever so slightly. His eyes sparkle with warmth and affection as he looks up at you.

"So... how have things been without me? How are everyone else?"

Frisk ducks his head shyly, brushing a stray strand of hair behind an ear. "Well, I was... lost for a long time. After I fell through that cave, I found myself deep underground in... another world. The people there took me in and cared for me." He pauses, looking down at his feet briefly before continuing hesitantly, "And... well, while I was there, I learned about magic, and... they taught me how to use it..."

As he trails off, Frisk raises a hand to reveal a small glowing jewel clutched tightly in his palm. "This is what I've been using for protection since I left them. It hides my energy signature from other magical beings," he explains softly.

The pale flesh beneath Frisk's baggy clothes seems to bunch up as he squirms uncomfortably. "Well, I-I gained some weight when I was living with them. They said it helped me get stronger..." He peeks up at you from beneath his lashes, looking almost guilty about admitting it. "They fed me lots of sweets all the time, so... maybe that's why I got a bit bigger here and there," he adds sheepishly, motioning towards his rounder form.

"But enough about me! How have things been here? Have you seen anyone else from that other world?"

His cheeks turn an even deeper shade of purple as he admits, "Y-yes, most of it went to my butt..." He looks away self-consciously, clearly embarrassed by the mention of his newfound curves. "Sorry..."

Frisk takes a deep breath, trying to change the subject. "So, how about we go somewhere we can sit down and talk? There's so much I want to tell you about what happened!"

You slap Frisk's ass hard, causing him to yelp out in surprise and clench his eyes shut tightly. His face turns redder than ever, and tears begin to well up in his eyes as he whimpers softly.

"Ow... stop that... I'm sorry..." he whispers, his voice muffled through tears as he buries his face in his hands. You notice how tense his body becomes when you touch him like this; he squirms and twitches under your hand, struggling not to react more strongly.

Your words sting, though he knows they're true; it only makes him feel worse about himself. "I-I'm not used to being hit like that..." he manages between sniffles, still unable to meet your gaze. His voice trembles slightly, betraying just how shaken up he really is inside.

Frisk lets out a soft, quivering breath before looking back up at you with red-rimmed eyes. He swallows hard, trying to steady his voice before speaking. "Well, when I first met them, they were all like that... Even the boys," he says quietly, gesturing to his own appearance. "They didn't have any rules about who could be what... So, over time... I guess I started to feel more comfortable dressing like them."

He hesitates again before continuing, "And... they made me feel special. They liked having me around, so I did my best to fit in with them." The pale flush on his cheeks deepens as he confesses, "Some of them even wanted to..." He trails off, blushing even harder.

"I-I know I should've come back sooner," he whispers, tears beginning to trickle down his face once more, "b-but I was scared... and happy there... And I didn't want to leave them."

As Frisk listens to your question, panic and shame begin to well up within him. His breath hitches in his throat, and he struggles not to break down completely. "O-only one..." he finally manages to choke out, forcing himself to meet your gaze despite the tears that stream down his face. "His name was Asriel... He was... different from the others. K-kind, but a little cold at times... But we became close... and he taught me things..."

A shudder runs through his body as he relives those memories, and he has trouble finding the words to continue. It takes several long moments before he can bring himself to speak again. "We... became lovers, eventually," he whispers, looking down at his hands clenched tightly in his lap. "But it wasn't all bad... There were times when we would make each other so happy..." His voice trails off, thick with emotion.

"Both..." comes the quiet confession. Frisk glances back up at you, eyes red and puffy from crying. "He was my partner... We took care of each other... Even if I didn't always like what happened between us..." His voice cracks on the last word, her throat tightening painfully around the admission.

There's a moment of silence as they both struggle with their emotions. Finally, Frisk musters enough courage to ask softly, "Will you forgive me? For staying away so long... And for being with him?"

The question hangs in the air, hovering between them like a heavy weight. The hope and fear in Frisk's expression are almost tangible, his entire body tense with anticipation.

Frisk blinks back fresh tears, understanding your words but not quite believing them yet. He nods slowly, swallowing hard as he looks up at you pleadingly. "O-okay..." He takes another deep breath, trying to steel himself against whatever might come next. Then, reaching behind his neck, he unclasps a jeweled collar threaded through his shirt. With a quick motion, he pulls it off and holds it out toward you, revealing a strange mark etched into his skin beneath.

It appears to be some sort of magical brand, glowing faintly with pale energy. Around its edges, wispy tendrils seem to writhe and squirm, as if alive.

Frisk's face blanches even whiter at your question, his lips parting in a silent 'o'. Tears well up in his eyes once more, spilling down his cheeks as shame and guilt wash over him. His chest heaves with silent sobs as he struggles to form the words, finally managing in a quiet, broken voice: "We... we were monsters... There were times when I would help him trap others like us... People who wandered in from our world..."

He pauses, forcing air through his constricted throat before continuing: "And then... there were times when he... he would let me... hurt them..." Even as he says it, FrisK can't believe the words are coming out of his mouth; they feel like hot coals on his tongue, burning their way down his throat. "I-I knew it was wrong, but... Asriel said it made me stronger... Made me deserve my place by his side..." He trails off, looking utterly miserable.

"Wha-what do you mean?" Frisk stammers, confused by your request. The anger in your voice and the memories it brings back only serve to make him more upset.

He hesitates for a moment longer, not entirely sure what you want from him. Finally, fearing that disobeying might make you reject him all over again, he slowly squats down until his rear end is at eye level. "Here," he whispers shakily, presenting himself to you. Tears stream unchecked down his face, making tracks through the dust and dirt on his cheeks. "Please don't be mad at me..."

As if understanding your words now, Frisk nods slowly, swallowing hard against the lump in his throat. A shudder runs through his body as he prepares himself for whatever is about to happen. He leans forward slightly, pressing his palms flat against the ground beside him for support, offering up his most intimate part in submission. His eyes are locked onto yours, pleading for forgiveness despite his own confusion over what you truly want from him.

You take a step closer, looming above Frisk as he presents himself submissively before you. Your hands curl into fists at your sides, aching with the desire to touch and claim what has been denied to you for so long. Looking down at the pale, supple flesh spread out invitingly beneath you, it's clear that FrisK has never expected or prepared for this kind of attention; his innocence only serves to heighten the thrill coursing through your veins.

Slowly, carefully, you reach out and grab hold of his hips, fingers digging into the soft skin beneath his baggy clothes. With a smooth motion, you yank him backward until he's flush against your body, feeling the warmth of his rear end pressed firmly against your crotch.

"Mine," you growl roughly into his ear, relishing the way he whimpers at your touch. "Yours, to do with as I please." It's a possessive claim, one meant to assert dominance over him and mark him as your own.

For a moment, there's tension between you as he struggles to understand what is happening and what you want from him. Then, finally, he nods solemnly, lowering his head submissively as he exhales shakily. "I-I'm yours..." he whispers, his voice little more than a whisper.

Your grip tightens on his hips, pulling him closer still as you lean in and press your lips against the nape of his neck. The feel of his warm, yielding flesh beneath your hands only serves to ignite something primal within you, making you want to claim him completely.

As if responding to some unspoken command, Frisk begins to writhe and squirm in your grasp. He arches his back, pushing his ass further back toward you in an unmistakable offer of submission. "Please..." he moans softly, the word full of longing and need. "Please... take me..."

You hesitate for only a moment longer before grinning wolfishly down at him. With a quick, smooth motion, you grab hold of his underwear and yank them roughly aside. His pale ass, smooth and tender, is revealed to you, already flushed from embarrassment and arousal. Your cock hardens instantly at the sight, pressing painfully against your pants in anticipation.

Without another word, you lift FrisK effortlessly into the air, his legs wrapped around your waist as he clings desperately to your shoulders. His eyes roll back in his head as you carry him across the room, depositing him unceremoniously onto a nearby bed. "My pet," you growl as you position yourself between his spread legs, taking in the sight of his glistening folds and swollen nub. "Been a while since anyone's had you like this."

Frisk whimpers, his breath coming in short, sharp gasps as you lean in close, nipping gently at his lower lip before planting a firm kiss there. Your hand reaches between your bodies, finding his engorged length and wrapping around it possessively. "And we
