If you'd have to watch a couple have sex for the rest of your life, which ship or pairing would it be?
Be it straight, gay or with multiple partners or maybe just solo or with animal characteristics, who would you choose? Id choose the couple from the manga Badass, Alphonso and Dante is a current favorite. Firstly the long tongue secondly the tongue and thirdly quote on shower scene. Or a couple although the genre is never gonna go towards that dirrection but Skip Beat couple Ren x Kyoko.Theres so many to choose from! I wanna know who you'd choose~
