@ gothicshadow, i'm surprised you changed your tune, you look into it further?
while your reason is an alright one, you should wait. it's a demon, so you need to be ready for that, but more importantly, you're 14, even if i gave out summonings i wouldn't give a summoning for an incubus to a kid. if you're dead set on it, research. figure out all the strengths and weaknesses associated with an incubus, then you can find out how to summon it through your research, along with how to protect yourself and how to dispell it. and trust me, your answers are just a google search away.
