Having Netori Skills while helping a Protagonist to maintain his Harem

Shit! Shit! I am transmigrated into the Harem game but it is after the Protagonist caught every heroine. Not only that, I become his best friend but also the Protagonist is busy as fuck. I also have a mission from the gods, it is to help the protagonist to maintain the heroines while I am eating dog foods. Luckily, lady luck is on my side. I get a skill from the Goddess that can conquer Heroines' bodies. I am too late to get their hearts but it is not too late to get their bodies. As a best friend of the Protagonist, it is also my duty to please the Heroines' sexual needs. --------------- Additional Tags - Netori, Scum MC, Yandere, Action sub-plot.
