The luxray lived with a pretty bad trainer until she left, she one day found a shinx that she decided to adopt. About a month later he evolved into a luxio and that's when stuff got weird...  she used to give him baths when he was smaller but now hes kinda bigger and she likes it a bit... the luxio is still quite young but her excuse is that he's old enough to mate... so she might easily make him let her eat and suck on the sheath... but luxio doesn't really know since she didn't teach him so...
