weird transformative sex magic
@mona@cybre.space @kara@occult.camp @ghost_bird@witches.town which reminds me of the bit in Xenophile (the Phil Foglio comic) where a couple ride a horse to a standing stone circle and have sex, then wake up with the male (iirc) having turned into a centaur. they discover that the centaur-ness is transmissable via sex. this ends up (after a not-shown sequence) with their disgruntled horse having six legs.
