An otaku with a hobby of masturbating was reincarnated as the son of a great mage.

As soon as he was born in this life, he vowed with a goal of embracing women till his death.

That said, when he became 20 years old, the Demon Lord which was sealed by his ancestors revived, and now it is his role to seal it once again.

And that demon lord is sealed in a tower dungeon that is rumored to be impossible to capture.

However, by an unexpected coincidence, he had found out that the Demon Lord is also one of him, a kindred spirit from within,

so he joined her instead and filled several traps in the tower dungeon, and thus they enjoyed a s*x spree with all the women coming over!

I'm thinking of offering my Flame Sword for it.][ShadowEternal: Wait, what’s a Mountain Dew?][TimelessWanderer: Are you seriously considering trading your Emperor-grade sword for a mere drink?][DeathlessOne: It’s not just any drink. The taste is out of this world, It's even better than the heavenly wine.][ShadowEternal: {...}][TimelessWanderer: {...}][Everyone in the chat: {...}][RichNigga: You know what, I’m in. I’ll trade my Gold Deluxe Armor just to see if this Mountain Dew is worth all the hype.]
