Ecstrinsic's manga / #age gap(14)

It's a sin to like this but it's so hot. Sadly, it's just a oneshot. I'm somehow expecting for more...

An omega and his fated alpha... but a child?!?! Interesting... I wonder how they will do things from now on. Heh.

Harada-sensei, you never fail to amaze me.

Out of all the old/young stories I've read, this one seems to be realistic. Not to mention the old man doesn't look like a young person that just had wrinkles or random lines added to his face.
