Ever since Frisk moved in with Toriel and Asgore, he was basically their adoptive son. And as such, there were a set of rules that Frisk had to follow. And one of the rules was that the "parents' room", the room that Toriel and Asgore slept in, was off limits. Not that it wasn't nice to have his own room, of course, but something about that room struck Frisk as... oddly beckoning. He wanted to know just what was inside. He wanted to see the room for himself. But, the thing was, they would never let him even take a look inside. No matter if he tried to stare through the keyhole, or if he tried to quietly sneak in, he'd always get caught. Always. However, one day, things would be different. Asgore was busy watching TV, one of his favorite programs. Meanwhile, Toriel was busy at a conference meeting. Maybe this would give him ample time to see what was inside. Hey, it was worth a shot, right?

If not now, then when was he ever gonna get the chance? This was the perfect opportunity to take a look inside and end this mystery once and for all! Finally, on this day, he managed to quietly sneak into the room, gently shutting the door behind him. When he opened his eyes to see what the room contained... needless to say, he was shocked. The room was filled with all sorts of sex toys. Dildoes, anal beads, vibrators, you name it. And if that wasn't bad enough, the room was filled with all sorts of BDSM shit as well. Whips, chains, straps, ball gags, handcuffs, the works. Holy shit, what the hell was happening here?! Normally they were such kind, well-respected parents. Who knew that they were total sex addicts? They must have been loaded with these things!

Did Sans or Papyrus know? Did Alphys and Undyne know? Hell, did anyone at ALL know?! But what surprised him the most, was the fact that there were three seperate wardrobes, each labeled for which wardrobe would belong to whom. Each wardrobe was filled with slutty outfit upon slutty outfit. Gloves, stockings, panties, bras, fishnets, boots. Every slutty article of clothing you could think of, at least one of its kind was in these wardrobes. Frisk then saw the labels on the wardrobe doors, "TORIEL", "ASGORE", and... "OUR CHILD"? ...Wait a second. "Our child"? Did that mean... Frisk? What the fuck? No... they wouldn't... there was no way! Right? But... the sizes seem to contrast greatly with the other attire. Not to mention, one of the outfits in Frisk's wardrobe contained his signature stripe pattern.

The pattern that he wore when he first fell down. Frisk didn't know what to do at this point. This room was just a gigantic contrast from the seemingly normal house. He never... He never expected THIS to come from Toriel and Asgore, of all people! What kind of sick, perverted freaks were they?! He was so shocked, he just stood there. Mouth gaping, eyes widened. He was about to consider leaving this room, and pretending like he didn't see anything. He hoped to try and cleanse himself of the horrors he'd witnessed, not noticing the shadows of a familiar set of figures looming over him. It wasn't until he looked down that he saw the shadows and realized he was screwed. It seemed like Toriel had come back home earlier than Frisk expected.

"Well, well... so you found our little secret my child." The voice of Toriel was heard. "Sneaking into our room and especially while I was away? How naughty." Frisk was busted, there was no way he could get out of this one even if he tried. This was all so... when and how did this happen? Frisk turned around and stared at Toriel and Asgore, shocked and nervous, "W-Wait, no, I-I can explain...!" "Oh, there is no need to explain. You need to be punished like the naughty boy you are, right Asgore?" Toriel said and had a mischievous smile. Asgore nods and stares at the flustered Frisk. "Oh, I agree, Tori. The first thing we need to do is get him more prepared. Why don't you take off those stuffy clothes, Frisk?" Asgore said and chuckles. What the hell did Frisk get roped into? Frisk hugged himself, "N-No, please... D-Don't make me do this. I'm sorry... I-I won't tell anyone, I swear!"

But Toriel and Asgore ignored the boy's pleas and kneeled down to his level. Toriel grabbed Frisk while they tried removing his clothes, the female goat monster with Frisk's sweater and Asgore with his pants. "It's your responsibility for poking into other people's business. Besides, you've seen too much, my child." Toriel says and smiles at the nervous boy. Frisk was forced to have his clothes removed, revealing his naked body. Frisk blushed hard as he got stripped down, "Mmh, nnh... n-no..." "That's much better. Now, we have prepared a 'uniform' for you to wear~" Asgore says and gestures to the striped outfit that Frisk saw. So it was meant for him after all... How long did they plan this? "Go and try it on, Frisk." Toriel said softly and rubs the boy's ass with her hand.

Frisk whimpered as he felt Toriel rub his ass, "Mmmh..." He didn't seem to have a choice in the matter anymore, so he reluctantly went over and put on the uniform. Toriel and Asgore watched as Frisk wore the striped arm length gloves and stockings, he honestly looked like some kinda slut wearing these. The two must have done this for a long time, being monsters and all for long lifespans. But wait... when Asriel was alive... Did he know? There was too many things to think about. Better focus on the now. Frisk stared at Toriel and Asgore, now wearing the outfit and blushing hard, "H-Happy now...?" He hoped that it was just "he'd have to wear this for the rest of the day" or something. "Very. Now, we have to train you." Toriel said and smiles, seeing that the outfit was a perfect fit, showing the boy's best features and feminine figure.

He looked like a true femboy. "You're in this for the long run, Frisk." Asgore added. Frisk went pale, "...W-What...?" Were... Were they seriously gonna...? B-But he didn't want to... But he didn't think of them in that way. Toriel leans down and kisses Frisk on the lips, then, she grabbed his penis and starts jerking him off. Asgore, starts groping and touching the feminine male's ass, feeling it was soft and plump back there. "You are a lucky boy, Frisk~" Frisk panted and groaned, "Aaahhh! M-Mooaaah...!" Oh God, they were, they were actually touching him in his... his private places...! Toriel kept kissing Frisk, playing with his cock as Asgore gave the boy's asscheeks a couple of squeezes and even played with his balls. "You have such surprisingly smooth skin, Frisk~ I bet many people and monsters liked you~" He said and laughs a little.

Frisk grunted as Toriel and Asgore treated him like their plaything, "HHnnhh! Mmmhh..." God, they were so... they were relentless! The female goat monster parted and smiles at Frisk. "You are such a cute boy, my child~ It would be a shame not to worship and play with your body~" She says and starts taking off her clothes. Frisk blushed as he watched Tori take off her clothes, and saw her true figure. Those big breasts, th-those large hips... that bubbly ass...! How did Frisk not notice before...? She gave a sigh and discarded her clothes in a pile and lies down. "Well? Are you interested? I've been so hot and bothered, I thought I would never get done with that meeting." She says and gives Frisk a playful wink. The sounds of clothes removing could be heard behind him. Asgore must have followed his wife's lead. "Well? What do you think?" Asgore asked the boy.

Frisk blushed, not knowing what to say, "I-I... Y-You look..." "Why don't you go over to her, Frisk?" Asgore suggested, giving the flustered male a gentle push. Frisk decided to just go along with it, walking towards Toriel, still blushing as red as a bowl of fruit punch. Should he just be honest and tell her she looks... k-kinda hot? He was in this for the whole thing anyways, and Toriel didn't look kinda hot... She was absolutely stunning~ Asgore is one lucky man to be with her. Toriel just smiles at and stares at Frisk. "Is there something you wish to say?" Frisk decided to confess, "...Y-You're so hot, n-no wonder Asgore married you!~" He almost wanted to flinch at what he said, but it was the truth, and he couldn't hide anything here. Not anymore.

Toriel just laughed and beckoned Frisk closer. "I'm flattered~ Would you like to play with your Mommy?~" She asks in seductive and lewd tone. Frisk looked behind him to see Asgore... and holy shit, he was an absolute unit, too!~ He was quite chubby, a bit like Toriel. But what he lacked in muscle, he more than made up for with... that package! Holy shit, no wonder they fell for each-other!~ He was at a loss for words with just how... hot they were!~ In fact... this didn't seem all that bad in hindsight. They were both attractive and each had their best features. Man, Asriel was lucky have parents as sexy as these two!~ Plus, with all the kinky toys and outfits... Why not have some fun? No one would know. Frisk didn't know who to play with first. Mommy Toriel, or Daddy Asgore? Decisions, decisions...

He was very conflicted. But what did he really want? That was the question. Toriel and Asgore waited patiently for Frisk's decision, seeing that he no longer resisted anymore. Frisk decided to have some fun with Mommy first, "...I want you to play with me, Mommy~" Toriel smiles and went over to Frisk. "As you wish, my child~" Frisk was so excited, he wondered what his Mommy was gonna do first. Maybe she could get Daddy involved too? That'd be great~ Toriel wrapped her huge breasts around Frisk's cock, the reached down and started giving him a blowjob. "Mmhhf...~" She swirled her tongue on the boy's penis and bobbed her head. Asgore watched as his cock twitches at the lewd sight. Frisk groaned, "Aaahh, ooooh M-Mommy~..." God, this actually felt good!~ Why didn't he do this before?!

As Toriel was servicing Frisk, Asgore began rubbing his cock between the boy's asscheeks. "You're lucky you have to deal with two of us, Frisk~" He said and chuckles, watching his wife suck and please Frisk as if she were a professional whore. Frisk groaned, "Haaahh~ M-Mommy, Daddy~... T-This is so good, mmmf~" He felt Toriel swirl her tongue, and rub her soft, furry boobs on his femboy dick. This... this was Frisk's destiny, he was... He was meant to become their femboy slut!~ Toriel sucked deeper on Frisk's cock, tasting every inch of his femboy length, Asgore started to slowly push the tip at Frisk's hole until it squeezed inside. Frisk groaned, "Aaghhh!!~ Hhah, D-Daddy!~" He grunted and moaned as he felt Asgore's massive length inside of him. Asgore held Frisk's waist as he started moving his hips, thrusting inside the femboy's ass. "Mmhhg... such a good ass~ I bet my cock feels good inside, doesn't it Frisk?"

Frisk nodded, "Y-Yes!~ Ahh, i-it feels so good, Daddy!~" His mind was shattering more and more as he got pounded and fucked like this. This was the best thing that could've ever happened to him! The two kept using and fucking Frisk, Toriel doing her best to please his cock with her oral skills and her huge, soft breasts. Asgore kept pounding inside Frisk's tight anus, hearing the boy's slutty moans. Frisk panted, he was already about to blow his load from just how good Toriel was at pleasing him, "Aahhgh!~ I-I'm... I'm gonna...!~" Toriel could taste the precum leaking out, the boy was getting close to climax. He couldn't hold it in anymore, and soon, his load shot out of him like a cannonball of semen, "AGGHHHH, YYESSSS!!~" "Mmhghgh!~" Toriel gulps and swallows Frisk's cum, the warm semen tasted so good down her throat.

Frisk grunted and moaned as he now focused on Asgore pounding him six ways to Sunday, and there was no signs of him letting up either, "Ahhh, m-more!~ Pou... Pound me harder, Daddy!!~" Asgore groans and goes deeper inside Frisk, giving the femboy exactly what he wanted. "Mmhhg...! You asked for this~!" Frisk could practically see the bulge in his stomach as Asgore went to town on him, "Aahhaghh!!~ S-So good!~ I love you!!~" Hearts were in his eyes as his mind was almost completely shattered. Toriel pulls away from Frisk's cock and swallows the last of his cum. She sits back and watches as Asgore showed no restraint in fucking the shit out of Frisk. He even pulled the boy into a full-nelson position so his wife could see Frisk in all his slutty glory. "Mmhgh...! You love being fucked, don't you?~ You love being treated as a toy?!~"

Frisk's eyes rolled back and his tongue lolled out, "AHHH!!!~ YHESH!!~ Aahhaahahahaahaaha!!~" He giggled and laughed insanely as he got humped. God, he never wanted this feeling to go away!~ "Will you be our toy, staying with us forever?" Asgore asked, the two watching as Frisk's mind was deteriorating as the session continued. The slutty femboy looked like he died and went to Heaven, he was so happy! Frisk nodded, "YHESH!~ I-I's slutty Frihsk ferevur!!~" He giggled dumbly as he said that. Yep, there was no getting around it at this point, Frisk was completely and utterly broken. Even if they asked him at this point, his broken mind was made up. He was here until he dies. Asgore was getting close, fucking the broken boy's ass faster and harder.

"Mmhgg...! Good answer... here's your cum!~" He gave a loud moan and filled the boy up, his stomach even getting bloated by the huge load. Frisk moaned loudly as his eyes rolled up and his stomach bloated like a balloon, "AAAAAAGGHH!!!~ C-CCUUUUUUMM!!!~" Frisk didn't even care if anyone heard him screaming bloody murder at this point, this was fucking amazing!~ Once Asgore was done, he pulled out, Frisk's ass was gaping and leaking cum, as for the state of the boy however? Well... Frisk was broken beyond repair, giggling dumbly and feeling the warm cum in his belly, "Hahhaahha... so good~" Toriel laughed at that, seeing how broken and slutty Frisk has become. "Would you like more, my slutty child?~" She asked him. Frisk nodded, "Y-Yeah... I love you, Mommy and Daddy~ T-Thank you...~" Asgore sets Frisk down, there was no going back anymore. Frisk's life and fate were sealed forever.

And why would he ever want to stop? He can have fun with his Mommy and Daddy all the time!~ And so, nobody really knew what happened to Frisk after that. Nobody except Toriel and Asgore Dreemurr, that is. More and more, he was absent. No one knew what happened. Even some of the students in Toriel's class wondered where he was since they go together. When the day was over or when there was no school, they were in that room, being the perverts they were behind that door. And thus, the story of Frisk seemed to end. Or was it beginning anew? Nobody knew. Maybe that was for the best, though. Regardless, Frisk was never seen again. Only two monsters knew where he was, if they was willing to tell, of course~...

As for Frisk, he never cared about anything. Why would he need to go outside? No reason. School? Who needs dumb knowledge? Sex was all he needed, especially by his living Mommy and Daddy~ Frisk's mind never recovered, he was in a permanent state of lust and horniness, always eager for his Mommy and Daddy to use him like the living sex toy cumdump he's become. Nothing else mattered and no one ever knew the true story of where Frisk had gone too. And even if they did find out... the damage was already done and Frisk never wanted this bliss to end~ He would please Asgore and Toriel Dreemurr until he dies. As a toy, he has a responsibility to please his loving parents~ Inside the forbidden room, all you could hear is insane laughter from a certain boy as Toriel and Asgore milked him for that's worth~...

-- THE END. --
