    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.

    Sans was always careful to make sure his brother didn't see him in heat, so it's particularly awkward when, this time, Papyrus sees everything. Good thing Papyrus is prepared to take care of him no matter what the trouble.

    Summary

    Mutt was in heat.

    Normally, he could deal just fine. He'd get himself off, find someone willing, or just power through it. But now that there was a human living in the house, he was finding it hard to control himself.

    Too bad said human finds out by accident.
