Fluffy fetish porn, featuring: magic slime inflation, horn job, horn penetration, orgasm denial, goofy innuendo, and explicit hardcore snuggling. This story was a commission, from a patron who shall henceforth be known as Anon no.2. Also, this was inspired by one of plasma-snake's art pieces; I probably can't link directly from here, but it's #39969 on Derpibooru.

Thanks to:
Anon no.1 for help pre-reading and brainstorming,
Anon no.2 for being an all-around cool guy,
the crowd on /trash/ for encouraging me to think weirder.
