the doll

tl;dr you fucked up and now your obedient fuck doll is a cum-crazed menace. Being the twisted, mad wizard you are you decided to make a fuck doll. You assembled everything you needed: scavenged golem parts, arcane crystal, magi foci, virgin blood, an orphan heart, you know the usual. After carving out the magic circle you lay out the materials and begin the incantation. This fuck doll will be perfectly sexy and obedient. Maybe even a little cute like a maid or something. You get through most the incantation but you sneeze and fuck everything up right at the end, even messing up part of the magic circle.
