Abyssal magic

You have dominion over demons and all their powers. While other mages summon a demon for a while, you are able to anchor them into the world permanently. Lesser demons jump at a chance to be summoned by you, even if it means lifelong servitude. Greater demons happily accept your summons and even offer payment to you to be summoned. Even the higher demons, who usually despise being summoned are willing to let you call on them.

This is of course mainly possible due to your heritage. Your human mother, an amateur demonologist miscast a summon and accidentally called upon a higher demon. A Devil to be specific. She apologized profusely for disturbing the great one’s peace and offered to repent for her transgression. Your father quickly noticed how sexy your mother was and told her she could apologize by letting him have sex with her. Your mother, honored that that this lord of hell noticed her in such a way, gave him the night of his life. She fucked him for hours. Over and over again until her pussy had sucked every last drop of sperm from his testicles. All the while hoping her sinful womb would conceive his unholy offspring. Luckily for you, she did.

Since you were born with horns, your mother and her cultist friends had to keep you hidden all the time. Over the years she became a better summoner and once you were old enough, she passed her skills on to you. At first, you summoned demons so you could play games with them. These demons were your first friends. Then, when you turned 18, you became interested in a different kind of game. Which is when you started summoning female demons. Whenever you got horny, all you had to do was summon a horned babe from hell and she would let you use her cunt, mouth or pussy whichever way you wanted. Out of all the teenage boys your age, none probably had more one-night stands than you. At age 25 your body stopped aging and at 35 you made your first permanent summon. A demon that no longer had to return to hell, but could stay in the material world forever. A few weeks later the war started.

Your mother’s cultist friends were the first to flee. Understandable, the country that attacked yours was much more religious than the one you lived in so their tolerance was far lower. But since your horns make you a giant obvious target you had to stay hidden at all times. Then one they, your mother went out for food and didn’t come back. Later that day you saw on the news that your mother had been found out for being a cultist. The bastards even executed her on camera. In a fit of rage, you stormed out of your hiding place. You used your demonic speed, strength, reflexes, superior aim and regeneration abilities to destroyed an entire enemy company by yourself. You were exhausted, but to the resistance you were a hero. Their savior. They looked past your heritage and offered you to join them. An offer you happily accepted. You then summoned a small contingent of lesser demons and used them to fight off more enemy forces. Then you summoned greater demons whom you had fraternize with the resistance. Female demons relieved the soldier’s tension with sex. Male demons fought side by side with humans. Human females felt themselves attracted to both. In time, you cut the enemy’s supply routes. As a result, their armies further into your home country fell out of food and ammunition and were **** to surrender. Several thousand troops defeated without a fight. When the king of your country came to this city he found it already liberated by you. He congratulated you for your victory, recognized you as the leader of the resistance and awarded you with an honorary title, ‘The Demon Scion’.

After that, you joined your demon army with that of your king and invaded the enemy’s territory. Your demons were armed with guns and tanks either taken from the enemy or given to you by your king. You conquered villages, towns and cities. It was in one of these conquests that your eyes fell upon a particular individual. One that you decided to take captive and have some interesting times with later.
