You cast a common incantation to steal the girth from the Goblin Matriarch's ass and add it to your own. Having a bigger, fatter ass, on top of being plain ol' sexy and fun to play with and sit on, will give you an easier time handling any obstructions that your enemies might try to force into you.



The Alpha Imp can't help but groan at the sensation of the meat and cushioning leaving his ass as you relentlessly fuck it through the spell. With every moment that passes, the pillows of his ass shrink and push into his pelvis, giving him less and less of a bubble, while your own fills and expands beneath you. Although, you try and keep in mind that a bigger ass, while fun to play with, means that if it gets too big, you'll be a bit off-balance, and losing your footing would mean you'll have a harder time getting back up.



The Alpha Imp grunts through his nose as another wave of pleasure shoots up his spine from the combined sensation of the spell giving him that little extra push, and from him basking in his submissive position beneath you. As he cums, the expanse of his ass continues to recede into his body, making it just a little more flat and giving him less protection from not just a dick in the ass, but from things as inconsequential as sitting on something too hard.



By the end of your incantation, your ass is now immeasurable; no mortal could withstand its might.





Finally, after what feels like an eternity of the Alpha Imp cumming his brains through his ears beneath you, the stream of his jizz and the constant shaking and rocking of his body begins to peter out. His exhausted body begins to relax into a heap, letting you know that your time with him is very nearly over.



You take those precious few moments of him being too capable for your magic to work and his body being incapable of resisting to finally cum yourself: with one last thrust into his tight asshole, you clench your arms down on his legs, and you make a hefty deposit of your own into his body. Every pump of your cock shooting your jizz straight into his asshole is another reminder that you had established yourself as his superior – a reminder that he’ll carry with him forever, provided he isn’t too lust-drunk on his own orgasm to remember anything.



For as powerful as your orgasm was, it still paled in comparison to his. But that’s for the best, honestly; you wouldn’t want him to recover while you were still vulnerable yourself. Once you’ve finished unloading into your new bitch-boy’s asshole, you slide your 20-inch cock from him, still wet from your own loads, and you leave the Alpha Imp to recuperate on the dirty campsite ground.
