Bella is your pet catgirl. She's been very clingy for the past few days and you wonder why.

One day, you come back home from buying groceries, only to see Bella sweating excessively and breathing heavilly.

She quickly notices you and gives you a lustful glare before tackling you and pinning you down on the ground.

Master~! Oh, I really need you for something..!

Observing her behavior, you realize that it's possible that she's in heat.
