Otoko dake no Party de Dungeon Kouryaku Ikeru ka na?

Raz, a highly knowledgeable and wise man, has come to recruit a new party for the hero. The previous party disbanded due to female ties and other issues!
So, it was supposed to be a strong and reliable all-male party! But...

Raz fell into a trap:
"Skill Boost by Semen Extraction/Succubus."

Following his unexpected early blunder, he took action:
"Extract semen from the hero."

It was a crazy trap that allowed him to multiply his own skill boost by pouring the hero's semen into his body!

Extracting semen allowed the hero to devote himself to conquering dungeons, but Raz's semen extraction skills grew stronger with each passing day! What was the price of gaining such a cheat-like ability...?!?!

For those who want to immerse themselves in the charming cuteness of a cute boy from another world!!! A boy who has fallen into a female role!!
