Oh fuck, seriously? Congratulations, you dumb shit. You did not summon an unholy creature of base desire outside proper binding and control circles. What you have done, is used a idiot trap. In other words, it's a succubus summoning ritual that does not actually summon a succubus (thus asking for your soul in return for teh spellbook, not taking it since you didn't bind it properly, or attempting to lure you into a Dark Contract). What you've summoned, is a homunculi designed to look like what people think a succubus is. It's a glorified sex toy.
It's also highly illegal, since it violates all the international laws concerning creation of semi-sentient magical constructs, anti-slavery laws, and a whole host of Misuse of Magic laws. There are very few spellbooks that have spells tied to those, these days. They're been rather routinely hunted down and destroyed.
Let me guess, a fifteenth edition 'Mastery of the High Artes of Summoning' or a copy of 'Rituals of Summoning for the Established Wizard'?
In either case, you're completely fucked. Those things weren't meant to be banished or unsummoned. Hell, they're not even really summoned, they're more created. Good news: You just tripped about half a dozen scrying lists, and the authorities will be there shortly.
Kids these days need to learn to research their spell grimoires.
- Oh fuck, wait, a government school. Could he have gotten ahold of one of the culled copies of 'A Primer on the Summoning Arts'? You know, it made all the news, teh head editor fucking hid a few dozen highly illegal spells in basic spellbooks for governemnt training facilities to show the "lack of proper understanding of the arcane arts." Ha, he might get off with a warning and his book being confinscated.
