Ah! Sky! I remember when Jack first started posting these images on DeviantArt! I'm sure some would be offended by them but, to me, they were knowingly innocent in the same way as the Carry On... films.
To me, Sky is pure fun. She's what Lara Croft of Tomb Raider would be if the stories had been written with the same comic edge as the Indiana Jones films and Angelina Jolie didn't take herself so seriously.
