~Maria's PoV~
After school, Maria couldn't come immediately as the principal asked her to do something. So she became busy with that. She knows that Arthur is gonna be busy, so she didn't inform him.
After work, she immediately comes to the house her parents left behind for her and her elder sister. And her elder sister doesn't always visit them. And she is using it for a year now as she is already about to divorce her husband.
When She come back home she saw the car parking and smile. Her down lips moistened as she feel very excited. She hurriedly opens the door with the keys and goes inside.
She saw that another pair of female shoes beside male shoes. Her excitement calms down a little. She understands that it's her sister. She walks to the switch to turn on the light but it seems there is a short circuit.
So she turned on the flash and start searching for her sister and Arthur. She couldn't find them down and walked upstairs the moment she come on the upstairs she heard the sound of moaning. She got a bad feeling and immediately walk inside.
She follows the sound and comes to the bathroom. She immediately shut open the door of the bathroom and coincidentally the light also come as if God also wants me to see everything.
She saw a stunned Arthur and her sister with excitement, pleasure, stunned and shocked as she look back.
~PoV change~
Arthur look at the door and saw Maria is standing there with shock and disbelief as she look at him.
A thought click on him 'then who am I fucking?' And turned to the person. Both of them look at each other in shock.
She has orange hair unlike Maria and a very beautiful mature face. Her breast is a little smaller than Maria but she has a big jiggly butt almost as big as the twins.
Arthur then again look at Maria and smile awkwardly as he said "I can explain" with his dick still inside the woman.
~scene change~
Arthur is sitting on the couch still naked and both sisters sit side by side on the bed. Maria is in her formal wear and her sister only wrap a towel around her body.
"So, you're saying because the light is out you couldn't see. So you mistaken her with me?" Maria Asked and Arthur nodded.
Maria look at her sister and asked "what about you sister Freya? Why didn't you tell anything?"
Freya rolled her eyes and said "stop so many questions. I didn't even see him before the light come. If I did I would have seduced him myself. Who would have thought the famous Arthur for whom women are lining just look once, was fucking my pussy a minute ago. Besides, why are you acting all good? Didn't you also seduce your student?"
Maria grit her teeth and said, "I am about to divorce unlike you who has 16 years old daughter and living happily."
Freya again said "so what, even this is my first time having a relationship outside of my family. It's just I couldn't hold back when I feel his dick. You are strong that's why you are getting divorced but I wasn't so courageous like you."
Maria also returns normally as she also knows that her sister wasn't also happy with her sex life and because of her daughter she didn't move out.
Arthur uses telepathy and read all of this. He doesn't want to mistake again. Besides he doesn't care about it. Both of them are the same, Sex craving women. He is indeed the second partner for Freya but Maria, he is third.
Freya then unwraps her towel and walk to Arthur and grabs his dick and said: "as we are the same, share him with me." She then gets up and spread her leg and sit on Arthur dick as his dick goes inside her pussy.
Maria watches her sister fucking the person she has been seducing for months, stop thinking about it anymore. It's not like Arthur is her boyfriend or anything. Even if she has developed a little feeling for him most of the others are only sexual feelings and Arthur is also the same towards her.
So she decides to do what she wanted as her sister is right in everything she said. She didn't wait anymore and started to take off her clothes as she look at her sister and student fucking each other. She also can see her sister pleasurable smile.
Arthur looks at Maria undressed and Freya riding his dick as he sits on the couch.
