Jjukkujjukku Yeohaenggi

“Jjukku Jjukku” (Hyeon-U), an alien drifting through space, crashes-lands on Earth after running out of fuel. But to collect fuel, he absolutely must have sex with a human...

*“Can't you have sex with someone else instead of me?”

“No, human!!”*

Ki-Beom, who accidentally picks up the alien Jjukku Jjukku (Hyeon-U) as he’s rambling about sex, will their first sexual encounter go smoothly?
