(Based on the Darky version of Frisk and Chara)

To say Frisk's life was strange would be an understatement. Having fallen into the mythical Underground, meeting and creating new friends, fighting for his own life and soon freeing the monsters so that they can finally leave their old home. Oh and having the ability to change the fabric of time itself. Frisk's life was strange, but he never used that for malicious purposes.

Despite Sans original doubts about him, Frisk truly never wished or caused harm to others. He would never raise a fist, even if the person or monster deserved it. It was because of this kindness and Determination that Frisk was able to overcome Asriel and save the world. However, he felt like that wasn't enough...that there was one more soul....

Chara

Asriels old friend, who died and caused her friends death. Despite the warnings Sans gave him, Frisk wanted to at least try and help her. Using the souls of the six human children, he managed to bring Chara back to life. They were still children at the time, but Chara's mind was nearly broken beyond repair. He still held that scar when Chara slashed his chest. Years upon years of being dead and stuck in a limbo like state had shattered her mind. Frisk knew the risk...but he wasn't one for giving up on someone.

Weeks and months would pass, ever so slowly and with the help of his family and friends, Frisk would spend every moment he could helping Chara. She threatened him, nearly killed him on multiple occasions, but slowly she was beginning to get better. Her personality shined when she began to get comfortable with Frisk. Turns out she's a hotheaded jokester, though that wasn't all as she's also protective of her friends. Frisk is pretty sure that one guy needed therapy when Chara threw a knife near his neck.

Everywhere that Chara went, Frisk made sure to follow not only to help her but also keep her in check. This was especially the case when they both enrolled into high school. The amount of times that Chara threatened to cut someone or break down into tears due to the stress of homework was far more than Frisk would like to tell. But it was around this time that...something was beginning to burn inside them.

Chara would often stay close to Frisk, holding his hand and even asking for hugs on occasion. Sometimes Frisk would wake up to see Chara had snuck into his bed and was snuggling into his side. Frisk would feel this burning in his body whenever he saw her, touched her, even being near her. The end of their junior year began the next step of their story...their romance.

When Frisk brought the news to his friends, he was surprised they were all supportive. Even Sans, who originally told him that helping Chara was a lost cause, told him to go for it. Undyne gave her own, usually bad, dating tips. Papyrus promised to make a spaghetti with a love potion, to which Frisk declined. Muffet gave a special lovers coupon to him. Toriel was fully supportive, but on the inside she was extremely happy she would finally be getting grandkids. Asgore...was the exact same as Toriel. And Mettaton gave him a box of HotLand special...variety...condoms.....Alphys wasn't too happy about that.

But that was then, this is now the modern day. Frisk and Chara both in college. Years of work had finally paid off with Chara now making more friends and able to hold a conversation that didn't involve gutting someone. Though...now both adults, Frisk didn't really expect the enormous growth spurt they had. Frisk himself had become somewhat of a stud muffin. Those training sessions with Undyne and Papyrus had given him an absolute killer set of muscles. It was kind of embarrassing when he would go to the gym or pool and see girls staring at him.

It was even worse when Chara usually turned to her murderous ways and scared them off.

Speaking of Chara she uh...GREW. If you were to tell Frisk that Chara would turn into an absolute babe then he'd probably chuckle. Everything Chara wore she made look small. Her breasts often strained every piece of fabric she wore. Her butt and hips would make any mom jealous despite having never had children. Frisk swore she only wore khaki pants to help her butt stand out more. There was one thing that Frisk hoped she wouldn't be freaked out by....

Yes they have kissed before. Yes they have touched each other before, mainly Frisk touching Chara. But he was nervous that when he took off his pants Chara would get scared. He had talked to the doctors before but they said nothing was wrong with him. Frisk was just...HUNG. Extremely hung. Obscenely hung to the point he had to make shopping trips every week due to his underwear tearing the moment he got a boner. It was a blessing...but a curse as well.

All these thoughts and memories Frisk was having was interrupted by the sound of the apartment door opening and slamming shut. He got out of his room, smiling softly as Chara walked inside and sat on the couch. She let out a loud sigh, throwing her shoes off and sinking into the soft cushions of the couch. "Finally! Summer is here!" She held her hands out. That is true, Summer break had just arrived for the two. With their new classes already scheduled, the only worried these two had were on what to get for food tomorrow.

Frisk slowly walked over and leaned over the couch, wrapping his arms around her neck and pulling Chara up into a soft hug. Without saying anything, the girl smiled and wrapped her arms above her and around Frisk's neck. They stayed like that for a moment before Frisk kissed her head. "You excited?" He asked as he jumped on the couch next to her. "You bet! God damn I'm so excited! No more boring work, no more frustrating tests, just us two and the summer days ahead!" She smiled widely. "I'm guessing you already have plans?" Frisk asked her as he rubbed her hand. "Duh, I already asked the others if they wanted to come to the beach this weekend. Next to Mettatons new resort."

Now that, was something Frisk was worried about. He was already aware of her busty body with normal clothes, but with a swimsuit? One that would possibly be far too small for her? That...was something he would be worried about. Chara didn't notice this as she snuggled into his chest. "Man Frisk...when did you get so buff?" She asked as she rubbed his arms and stomach. "Fuck dude I think I can feel an eight pack!" She smirked as she pulled his shirt up, seeing his abs and licking her lip. "C-Chara please, I haven't even showered yet." Frisk blushed as he gently held her hands and moved his shirt back down. Chara pouted a bit but shrugged. "You can only stay clothed so long Frisk. I swear I'll see that naked butt of yours~." She creepily waved her fingers at him, making Frisk nervously laugh.

Getting up and giving a quick stretch, Chara turned to the bathroom and smiled back at him. "Sorry babe but I kinda stink, I'm gonna shower first!" She stuck her hip out sexily before walking into the bathroom. Frisk blushed at the sight before nodding. "Don't use up the warm water....again." Frisk asked her. Chara stuck her tongue out. "No promises~." She took off her shirt and closed the door behind her, the sound of the shower turning on being heard soon after. Frisk blushed softly when she did that, soon getting up and walking to his room. He didn't really need to shower, he was mainly a morning shower guy. Frisk's eyes fell to the books he has collected and grabbed one, laying down on his bed and resuming where his last page was.

In the shower, Chara's mind was amiss with jumbled thoughts. Her hands slathering the soap all over her beautiful body. "Damn it, that stud muffin...." She felt her fingers slowly rub down her stomach and to her sex, shoving a couple of fingers inside of her pussy. Slowly she thrusts them in and out, moaning softly as she leaned against the wall. "Frisk....oh why can't we...just embrace completely?" She asked herself as she fingered her pussy faster. Her hand grabbed her massive breast, squeezing it and moaning out. Was it her fault they haven't embraced? Was Frisk just scared? She wouldn't blame him, she did cut him all those years ago. But she would constantly try to rectify her mistakes. To make Frisk embrace her....

She pulled her fingers out of her pussy, looking at them. The water washing off her juices as she panted softly. "Frisk....I'm ready for you~." The deed was set. It was either going to be now, or someday far in the future. She was going to feel his...no...their embrace. Turning the shower off, Chara didn't even grab the towel to dry off.

Flipping through a page once done reading, Frisk's eyes fell to the new collection of words. This story, one of an ancient desert holding eldritch secrets, was very captivating to the boy. Even when he heard his door open he didn't look up. "Chara? You okay?" Frisk asked. When he didn't receive an answer, his eyebrow furrowed before looking up. His eyes opened widely, his unique golden colored eyes basking in the sight of a wet and naked Chara. "Friiisk~." Chara smirked as she leaned on the doorway before walking over and climbing up on the bed.

"C-Chara?" Frisk gulped, trying his best to remain calm as his naked and thicc girlfriend slowly climbed on top of him. "Frisk...why are you still clothed?" She asked. "Because....I don't wanna be naked?" He asked nervously. "Lame~." She grabbed at his shirt and tore it off. Damn, there went a good fifteen dollars. Chara's hungry gaze fell to Frisk's body, leaning down and kissing at his pecks and abs. The boy shivered softly as he felt her tongue slather his abs. "C-Chara are-"

Chara silenced him with a finger to his lips, moving her mouth down and biting at his zipper. This caused his eyes to widen, scrambling up in nervousness. Luckily, Chara noticed this. "Hey...what's wrong?" Chara asked.

Frisk gulped a bit as he looked at her beautiful red eyes and cherry red cheeks. "C-Chara....I don't think you'll like it when you see me in full display..." Frisk muttered. "Frisk, shut the hell up." This caused the boy to look at her with a confused expression. "I don't care if you're tiny or not, I love you and I want to finally embrace you. Soul to soul~." She licked her lips and finally pulled down his pants. "Chara NO!"

A silence fell between the two, Frisk nervously looking at her with his golden eyes. Chara stared in shock and...honest to god nervousness. His semi-erect member was mere inches from her face, just the sight of it alone was filling her with horny dread. "F-frisk...are you sure you are fully human?" She asked with a gulp. Frisks member was a good length below his knees, with a massive set of balls that put grapefruits to shame. The more Chara stared at it, the more it awakened something deep inside. The burning they felt for the last few years, staring as a soft ember, has now erupted into a raging inferno!

"Holy fuck Frisk...where the hell have you been hiding this~?" Chara licked her lips as she stared up at the tip. "W-well it's a combination of luck and extra large underweAHH!" Frisk groaned out as Chara immediately took his member into her mouth. Her eyes stared up at him, slurping on his cock as she felt it harden more in her mouth. Without warning she pushed her head down more, feeling his member push down her throat. Slurping and gags filled the room as Chara repeatedly moved her head up and down on his massive member. Her hands grabbed onto his thighs, pushing her head up and down as she expertly deepthroats his cock.

Frisk was gripping the pillow roughly, gritting his teeth as drool fell onto his chin. How was she so damn good at this?! He shivered when she grabbed his fat balls, giving them a soft squeeze. Chara moaned out as she felt his precum spurt into her mouth. 'Yes...come to me~.' Chara thought as she sucked harder. Frisk's grip on the pillow tightened as he subconsciously thrusts down her throat. "C-Chara I'm gonna!" He stuttered out as he thrusts his hips up. Chara's eyes widened as she felt an enormous load of cum entered her mouth and force its way down her throat. 'HOLY SHIT!' The voluptuous woman thought as she felt her stomach begin to fill up. 'SO MUCH! IM IN LOVE!' Chara's eyes turned to hearts the more she felt his creamy load fill her stomach.

After what felt like forever, Chara pulled off and panted heavily. "Holy...shit...that was...amazing~!" Chara smiled at Frisk as she suddenly laid on the bed, spreading her legs out and holding her arms out. Her naked and wet body was there for him to melt his gaze into. Frisk stared down at his girlfriend as he got on top of her. Everything was so perfect about her. Her face, her breasts, her hips, her thighs, her ass, her personality. Everything...and it was all for him.

"Chara...tell me to slow down if you are in pain." He told her as he held her cheek in his palm. "Don't worry, I'll be fine~." She smiled up at him as she stared into his eyes. Frisk smiled as he starts to slowly push his cock into her waiting pussy. "Oh FUUUUCK~!" Chara suddenly hugged him as she felt his massive member stretch her out. "Shit! Shit! I forgot I'm still a virgin!" She panted out as she bit into Frisk's muscular shoulder. Her lover was going to pull out, but she wrapped her legs around his waist. "No...keep going~. I'll be fine Frisk." She kissed his neck before biting at his shoulder again the more he pushed in.

Frisk stopped when he felt he was at her barrier. With a nod, he wrapped his arms around her and thrusts in. All at once, his cock filled up her pussy. Chara squeaked as her teeth dug into his shoulder. It was painful, but Frisk has felt worse. Feeling his lovers breasts on his chest, near that scar, it felt so invigorating. Slowly but surely, he began to thrust into her. Chara let out soft moans, her legs around him tightening as her pussy squeezed on his cock.

Frisk moved his head up, his hips going at her harder and faster. Chara continued to moan out, her stomach bulging out due to the sheer size. Each thrust he gave her, she felt her womb be penetrated. Without warning, Frisk leaned down and kissed Chara deeply. She widened her eyes, but rolled them back as she felt his tongue play with hers. His thrusts now going harder and faster, making her body shake as waves of pleasure filled her core. Their fingers interlaced, finishing their romantic embrace as the bed shook with each thrust the stud muffin gave his once psycho girlfriend.

Frisk pulled back barely, his eyes staring into her red rubies with utmost love. "I'm cumming Chara....inside?" He asked her as soft pants breathed on her lips. Chara nodded, her legs around him getting tighter. "I don't know if I'm going to get pregnant from this....but I don't care! I want you Frisk! I want to stay with you for the rest of my life! I love you Frisk...give me your children~!" With her words, Frisk kissed her deeply once more, thrusting as hard and fast as possible before slamming in. Chara's eyes widened to saucers as she felt an absolutely enormous load of cum filled her womb. So much, it leaked out of her pussy, but he would not stop! She groaned out in ecstasy as her belly began to slowly get bigger.

Frisk most of the time? A wholesome stud muffin. Frisk in bed? A horse with as much love juice as a wine barrel.

Chara wouldn't have it any other way~.

Frisk slowly pulled out, watching with confidence as Chara laid there in a sweaty mess. Her hair disheveled as cum poured out of her pussy. Her breasts heaved up and down as a face of pure ecstasy was plastered all over her features. Frisk slowly laid down next to her, wrapping his arms around her waist and pulling her close. His lips kissed at her cheeks and neck, telling words of praise and admiration. Chara weakly wrapped her arms around his shoulders, kissing at his face and head.

Finally, she had his embrace~.

(Epilogue)

"NYEH HE HE! THIS IS TRULY THE LIFE RIGHT BROTHER?" The loud and rambunctious voice of Papyrus filled the air as he stepped out of his car. Sans chuckled as he got out, both brothers adorned in goofy Hawaiian attire. "It's definitely good, let's hope the water isn't BONE COLD!" Sans chuckled at his own bad pun as Papyrus shook violently. "Oh hey it's Torbs."

Said goat woman smiled as she waved at Sans and Papyrus. They were the last ones to arrive. She was adorned in a one piece swimsuit, one that felt a little too small for her. "I gotta cut back on the pies...." She pouted, only to feel a pair of strong arms wrap around her. "You're still beautiful my love." She smiled softly as she held his hands. "Thank you Asgore~."

"YEAH COME ON! FIGHT ME!" Undyne, in a two piece swimsuit, was currently underwater and screaming at an eel who was hiding in the coral reef. Her wife Alphys was resting on the beach in a one piece, talking with the spider lady Muffet under her umbrella. Mettaton, in his box form, was for some reason trying to get a sun tan.

"Hey does anyone know where the lovebirds are?" Sans asked as he and Papyrus walked down to Toriel. "Oh, if I remember correctly they were getting some snacks." Toriel said. Mettaton overheard this and looked around, activating his scanners to find them. "Oh!" He muttered as his scanners saw a vital sign behind some rocks. "Better give them some alone time~." He said as he laid back down, applying more suntan lotion on his metal body.

"C-Chara." Frisk muttered as soft smacks were heard. "We've been gone for...twenty minutes....we should get back." He said, groaning as he felt his member get squeezed by Chara's ass. Said girl was drooling as she smacked her big ass on his crotch, feeling his member stretch her ass out. "N-not yet...not until you bust inside of me~." Chara licked her lips as she looked back at him with lust. How Frisk was going to explain this...that story is for another time....
