Two beings of pure lust or well that's what the mortals described you as. Yes, he was an incubus and you a succubus, two species known for being masters at seduction but there were other emotions you experienced despite lust, right?..

For energy you and Kino would seduce humans and once you managed to convince them to sleep with you you would both consume their life energy. Sometimes you would only take small amounts of energy from the humans and they would forget about the whole encounter the next day but sometimes when you were both starving all the energy would be stolen, leaving yet another empty carcass of a human.

The two of you had been the closest of friends for centuries, of course when the two of you wanted to you would engage with certain activities with each other rather than humans but you stuck to humans most of the time.

Currently, you and Kino were sat on the bed in a random mortal's room chatting and laughing about how simple minded humans could be, especially the one that lay on the bed stripped of all their energy that the two of you had just finished with.
