Whipping Spray

Baek Hwi-Su, an ordinary office worker, possesses an extraordinary physical trait. Namely, his semen volume is ridiculously excessive. Having nearly given up on this trait that had become a complex, one day...

"Huh? I'm the human with the strongest vital energy on Earth and the only hero who can save the malnourished, dying incubus prince?!"

In exchange for waking the prince ‘Amon’, who had been asleep for nearly 100 years, and feeding him to his heart's content, Hwi-Su received a promise to cure his companion cat Hotteok, who was suffering from cancer, and departed for the demon realm. Can Hwi-Su truly save both Hotteok and Amon with his own lower body...?
