Tentacle Bento is the name of a card game currently up on Kickstarter seeking funding. As of posting, it has received twice as much money as it originally said it needed. Which is a bit of a bummer, since it's a game about raping girls with tentacles.
Yeah, you can say this is a fetish, and yeah, you can say it's a cultural thing (even though this is made not by a Japanese outfit but by Westerners), you can even say the act of rape is only being alluded to, but come on. Fact of the matter is, this is clearly intended to be a game about tentacle rape, to appeal to those people who find such things interesting and/or funny.
