SadGirl's manga / #Demon Seme(2)

I’ll pour my magical power into you... Otaku salaryman, Momose, who loves fantasy and parallel worlds, comes upon a book that he used to read a lot in the past: “The Complete Collection of Summoning Magic”. Feeling nostalgic, his middle-schooler heart re-ignites, so he decides to try and chant once again the summoning spell to call The Servant of Fate... But suddenly, in doing so, a demon named Keiha comes out of his closet?! A slightly naughty BL daily-life story about a demon tied by an invisible force X a salaryman!!-

Yuuma, the unpopular host, summoned the incubus demon, Airucus, to grant his wishes. The contract's condition, however, was for Yuuma [to give birth to Ai's child.] Yuuma is forced into conceiving a child and accepts Ai's body fluids by receiving his semen. But despite the fact that he was unable to become pregnant, Yuuma's body was in excellent condition due to the special nutrients contained in Ai's semen. Yuuma became clingy after that and began to beg for Ai's semen himself—!?? Whether he gives birth to an incubus demon child or remains an unpopular host—- It's a difficult decision!!!
