Splice is a movie about a married couple of scientists who genetically engineer a hybrid female creature. They raise her as their daughter. The female scientist used some own DNA so it technically was her daughter in a sense. The male scientist and the creature become attracted to each other. The female scientist discovers them fucking and is horrified. That is the board-relevant part, spoilers for the rest in case you want to watch it first. They end up thinking the creature is dead, but it actually metamorphoses into a male because of frog genes or something. It rapes the female scientist, and kills the male scientist when he tries to rescue her, and finally the female scientist kills the creature. It ends with the female scientist pregnant with the creature's child, and she accepts a large sum of money from her employer to carry the baby to term. So yeah, monstergirl, cuckqueaning, genderbending, rape, impregnation, incest.. They really went all out with this one.
