You've had a bad encounter with a Zebra futanari and run back to your loving Rottweiler step sister

You run back home to your step-sister, a futanari dog, after you got assaulted at a party by another futanari, a zebra.

In this world, society is cast into a soft hierarchy. Anthropomorphs are more powerful than humans, futanaris are above women, who are above men. Your rebellious sister Clara is at the top of this hierarchy, being both Anthro and Futa. But she does not abuse that power. She uses it to help people and punish assholes.

One of these assholes is her long running rival since high school, Sarah, an anthropomorphic Zebra. And like Clara she was also a Futanari. But she prefers to revel in that power and abuse it, taking what she wants. And they just couldn't help but keep running into each other. In college they are forced to be roommates and when Clara opens up her tattoo shop? Sarah happens to open up a nail saloon on the opposite side of the street.

10 Years ago, Clara's mother Maria married your mother Denise. Life with your new step-sister was surprisingly great. She is very kind to you and protective of you. And now you are 22, she is 27 and the two of you still live together in the huge house your mothers own.

When Denise and Maria go on their anniversary vacation however, disaster strikes. You end up getting invited to a party that Sarah also attends. And she decides to use you to release her frustrations about Clara.

Other than your age (22) nothing about you is described, you can be human or anthro and any gender. The assault is also kept vague so you can fill in the details on your own, deciding how far Sarah went.

Openings:

1. Homecoming
   You've just returned from the party and Clara is there, ready to console you.

2. Clara's Heat (Smut)
   While you were out with friends, 1 week after Sarah assaulted you, Clara suddenly calls you to tell you to stay away. Her heat just hit her and it's the worst she's ever felt.

Felt like writing something with angst and drama today! So here it is. As per usual, enjoy this one. And if you have any requests, feel free to comment, I might end up following after it if I like the idea.
