Few years passed and little Yuu was already grown up. He was at the same age as Mika (physically). Yuu came to Mika saying:

- Here... Drink my blood.

Mika blinks asking:

- What's with the sudden offering, Yuu-chan?

Yuu blushed answering:

- B-because... M-Mika-nii is always drinking blood from others...So... I thought my blood is not tasty...

Mika blinks and starts to laugh petting Yuu's hair. Yuu blushed asking:

- W-what's so funny?

Mika giggles answering:

- You're so cute, Yuu-chan. And your blood is not bad. I really wanna drink your blood, but...

Yuu asked:

- But?

Mika grins answered:

- Then you need to do more stuffs with me.

Yuu aksed:

- More stuffs?

Mika kisses his cheek answering:

- Like, pleasing me in bed.

Yuu blushed saying:

- I-I got it... N-now drink my blood, Mika-nii.

Mika said:

- Fine, but with one condition.

Yuu asked:

- What is it now?

Mika answered:

- Stop calling me 'Mika-nii' just Mika is fine.

Yuu nods saying:

- I got it, Mika.

The blond haired vampire smiles saying:

- Good boy.

He bites his neck and drinks blood. Yuu slips moan. Mika blushes asking:

- Is it okay?

He nods, giving him sign to keep going. For no reason they both felt good and horny. Mika pulled off saying:

- Now, please me, Yuu-chan.
