Will Heesu Be Spared?

Hui-Su, who went out to find a meteorite to pay off his debt, discovers an alien life form called Bijou. Then, Hui-Su is suddenly attacked by an alien life form and faints. When he comes to, he finds himself having sex with a man who suits his taste. Turns out, this man is an alien life form?! On top of that, tentacles come out and start to stimulate Hui-Su, and Bijou eagerly eats Hui-Su...

I think I found a really good prey. This is the first time it's tasted this good.
