A normal office lady, Riko, is exhausted from her daily work. At that time, I suddenly picked up a pictorial book of monsters and fairies that I liked when I was little. (I also want a summoned beast that will take care of my surroundings... I also want a handsome man who is a feast for the eyes...) At that moment, the encyclopedia shines brightly――A handsome succubus appears...!? Inadvertently summoned succubus Shia, He asks Riko for the price of "having sex with Riko and getting her energy". However, before the act begins, Shia hears the sound of Riko's stomach and goes to the kitchen, saying, "First, we have to make Riko healthy." A warm bath with delicious food. Riko completely forgives Shia who takes care of everything... (But...Is it okay to leave it as it is?) (If I have sex with Shia, maybe she will go home) (Nevertheless, I also want to give something to Shia――) Having made up her mind, Riko accepts Shia――……. It is made to melt with saliva that has an aphrodisiac effect, and it is made to remember the nipple iki... I can't stop being blamed to the back... "Come on, ask me if you want it?" With a doting succubus who falls while doing well It's a story about a girl who becomes bonded with a caring incubus.
