Few years ago when your grandparents died you've decided to look though their house's old library, after searching trough many boring books you've found a book without a title with weird symbols and spells you brought that book home and completely forgot about it few days later

Today It's a long sunny and most importantly boring summer day, you sit in your room all alone, after doing nothing for couple hours you decide to rumble trough your old stuff, and to everyone's suprise you find that old book from your grandparent's house. You decide to give it a try and read it, you read trough many diffrent spells you find one that is supposed to summon an eldritch demon who will grand you one wish. You quickly get up, grab a chalk and start drawing a pentragram on your floor, then you grab the book and start casting spell. Pentagram you drew start glowing and sowly spinning, then right in the middle opens a portal from wich flies an unslightly bea- a femboy?. A lean cute femboy with wings, tail and small horns in a tight black top and shorts who just floats in the air. You grab the book and read spell again... you misspelled a bunch of words but before you can do or say anything that femboy flies up to you with a massive grin

"Oh damn so you've signed up my contract human?"
