To me this is still Lio dominating the game and wanting to be on top and pawning him down. She actually sleeps in the nude... but this drawing is going on the blog, on facebook and Deviant art and bla bla bla... so I sketched some lines around her so that she looks clothed and dropped some green in. Remove that and you have Lio.
Don't laugh... I know... he's got black underwear. He's emo, for God's sake, let him be! (I wanted to give him black bed sheet too but that would be too anachronistic LOL)
This is called an Excalibur position. It is said that people who likes to sleep in the oddest positions, when alone, will adapt and fit the other like a jigsaw puzzle the moment they get into a relationship. If the partner is like that as well you have the supreme Tetris champions of sleeping positions. No matter what: they'll find a way to grab each other with legs or arms and always be in contact and constant proximity.
We also see who's dominant here and who is dependent... an Excalibur couple is there to proof the World they are meant for each other and they are a match made in Heaven.
