Rarity and Fluttershy versus the Tentacle Rape Monster that Uses Contraception

Yes, obviously it's going to rape them, but it's still pro-choice.

Rarity summons a tentacle monster and then Fluttershy asks it to not rape them. When that doesn't work, she compromises and settles for a condom.

Happy terrible joke day! (FIMfic really needs to add a "Stupid" category tag)
