The art of summoning is more dangerous than people think! If you summon something stronger than you, you could end up being the slave instead of the master! Our protagonist has been playing it safe, summoning nothing but slimes, unfortunately the hero and the rest of the party are pretty sick of it and they kick him out! In a fit of rage our summoner friend pours all his mana (and dirty thoughts) into the most powerful summon of his life! Things don't go according to plan though, instead of summoning the sexy servant of his dreams he ended up being summoned by the Demon Queen herself! Shocked, afraid, and a little bit horny. The poor summoner prepared to accept his defeat at the hands of the Demon Queen Lucifer but he has one ace up his sleeve, the familiar binding ritual! As his last ditch effort he challenged Lucifer to a sex competition to save his soul and potentially enslave hers! See how the summoner fares in this twisted tale of betrayal, revenge, and the filthiest of sexy times as he conquers and breeds this busty Demon Queen!
