    Summary

    Sans doesn't know why he was attacked, he's so scared- He can't believe what's happened to him, and yet- Why is Red so kind? And what is this warmth in his soul...? He's never felt it before...He wants...to be close to Red. But he shouldn't want that, right? He should be disgusted with Red for what he's done to him!! And yet...Sans is only disgusted by himself...for he...doesn't want to let Red go...
    Red has a job, a job that he quite enjoys. He gives people their darkest desires. Some breaking and entering that ends in sexy time? Sure. Some heavy BDSM? He's down. Some rape play? He's cool with that. He was commissioned for a cute, small skeleton- And damn, was he excited. They were adorable, so small in his arms... But...their sobs were a bit too loud...Their shaking too real... They would say the safe word, right? They would stop this, right? Why aren't they stopping this? Just say the word!
    "Peppercorn", Red says, his voice hoarse as he looks into the sobbing monster's eye-lights.
    "...that's...a spice, right?" They responded between choked noises.

    Summary

    Tiffany Loves was nice and pretty, looking for a place to rent a room while attending college to be an artist. She finds herself staying at a mansion with eight skeletons and becoming friends with all them. In fact thanks to soul bonds she has become a lot closer then friends to them…

    This story though is a lot less about her and more about a certain assistant, the student majoring in engineer at the same college and assisting Sans in fixing his machine. His also nice as far as he knows, not bad looking, but never the focus of much attention. The stand-by friend for skeletons when Tiffany was too busy. He was ok with it because one specific skeleton appeared to like him a lot and he liked them very much as well.

    But then he finds out he was second fiddle even with that one skeleton compared to Tiffany. He leaves the assistant job swearing to have nothing to do with skeletons. Something goes horribly wrong with the machine though and nothing is going to be the same again. A little twist on the typical reverse-harem story.

    Summary

    It was a difficult task to find your soulmate, especially after monsters were free from the underground, double that once monsters from other dimensions started getting stuck here after coming through rifts. Sans had... a very strange connection with other versions of himself. Being the original, he stayed as far away as possible from everyone else, including people he knew and cared about.

    After years of trying to get his brother out of the house to try and socialize again, and at least meet with the new monsters from the rifts, and with no luck, Papyrus takes things into his own hands. Finally he gets his brother out with a little trickery, and hopeful that his brother would make a new friend.

    Nothing goes as planned.

     

    A rp between Fineapplequeen (Queenie) and ShadowHunter1215 (Auntie), Queenie as Sans, Auntie as Red.

    Summary

    Your stomach rumbled. Making you move ever so slightly. It was nearing your feeding time anyway. You ever so slightly lifted your head off of your battered arms to give an ice cold glare to the glass window that separated your room to the rest of the asylum. The glare you were currently giving the window was one of those glares that could render a full grown man helpless. You smirked once more at that thought. Though this time, your smirk was plainly visible to the people currently monitoring you from the safety of the other side of the glass window you were currently looking at. That's right. They were safe from you with being on the other side of the glass.

    Things to look out for:
    ~ Blood and gore
    ~ Mentions of violence
    ~ Cannibalistic notions
    ~ Horror topics
    ~ Upcoming intimate scenes

    WARNING: This story is very graphic, and not for the faint of heart! There are mentions of upcoming rape scenes, graphic depictions of violence, profanity, and a whole lot of blood and guts. This is rated M for a reason. If you have not already read the summary for this fanfiction, I highly suggest that you do. You have been warned, read at your own risk. This is geared for mature audiences only.

    Summary

    (Y/n), a high ranking Platoon Commander in the Military, was on a mission with her squad when her plane was shot down by an enemy ship, leaving her stranded on an unknown island, with none of her comrades in sight.

    It would have been all fine an' dandy... if she wasn't surrounded by three Alpha Skeletons and one Omega Skeleton. All of which want to fuck or be fucked by her.

    So now here she is, having to assess her dominance as an “Alpha” to get by with her limbs still attached and her clothes still in one piece. Even if one of them looks like he came straight from Satan's asshole.

    Summary

    " What..." You inhaled a deep breath through your nose, exhaling slowly out your mouth. "and I cannot stress this enough, the fuck. "

    It was in that moment Sans knew, he fucked up.

    "Well, ya see...princess..." he was hesitating to find the right words to say, and if the look on Y/N's face was any indication on his progress on doing so, he was failing horribly. Beads of sweat like magic started to form, dripping down his temporal bone. His perma-grin tight, he shifted his eye lights back and forth between you, Gaster, and the motley crew of skeletons that now inhabited the den.
