Never in his life, Zarc thought that his mate will be no one else, but his younger brother Yuya. Yuya was shy and cute omega wolf, so he was always teased for looking like a girl, even he was a boy. Yuya was smelling like strawberries. Zarc just couldn't resist this scent. No matter how hard he was refusing this scent, he end up horny and panting. It can't be help. Zarc was after all an alpha. 

- Alpha, tell us your orders. - Said the beta wolf, Yuto.

Zarc was spacing out a bit thinking of his younger brother, Yuya. Yuto got pissed off and hits Zarc yelling:

- CONCENTRATE YOU STUPID LAZY WOLF!

Zarc huffs saying:

- Shut up. It's hard time for me... I found my mate.

Yuto gasps asking:

- Alpha's mate? Who is the lucky one?

Zarc bites lips lips sighing and answered:

- Yuya...

Yuto came to him saying:

- No way... He's your brother. And an omega. 

Zarc said:

- I know, but I hate this nature! I want to fuck him so hard. His scent is too much strong for me. I'm afraid that one day I'll rape him...

Yuto smiles saying:

- Zarc... As your friend, I need to tell you something. I never expected my mate to be Shun. You know good how much strong is he. So, love doesn't see it that way. Yuya is weak, I admit, but you're strong enough to protect him. Now, go and mark your mate before someone else takes him away from you.

Zarc smiles saying:

- Yes, you're right, Yuto.

Zarc left to find Yuya. Yuya was sitting and playing with one ball as his tail was wagging happy. Suddenly, he notice strong scent behind him. He knew it. It was his mate, Zarc. Yuya slowly turned around and looked at Zarc saying:

- Hey... N-niisan...

Zarc pins Yuya on the ground and bites his neck marking him. Yuya yelps of pain and his eyes went a bit blank accepting his mate. Zarc let go of him saying:

- You're mine, Yuya~

Yuya nods smiling and said:

- Mate me, Zarc.

Zarc nods smiling and both take off their clothes. Yuya and Zarc got fun whole 3 days. Yuya was happy that his precious brother is actually his mate, forever.
