Is the size ok?

So damn cute!

Yes!

You don't need this collar anymore either.

U... Umm, thank you for everything, Master.

Nono.

More importantly, stop calling me Master. It makes me feel uncomfortable.

Then what should I call you?

That's right... how about Serena... Or Onee-san.

A little embarrassed when she says it herself.

Then

Serena-Onee-sama

U... Uwaaaaaaa

A, Are you ok?

So cute so cute so cute so cute so cute so cute so cute so cute

Don't worry about it. My back just hurts.

Bonus

I've bought a bed for you.

Wow! Thank you!

I'm really happy.

I... Always had to sleep in a stable, so I really wanted a bed...
