Caught watching

I am a female adult and it is my birthday. I was in bed masturbating quietly with my fingers in my cunt. When my father surprised me with a birthday cake in my room. He asked me to continue because he thought my body should not hidden and because he was aroused. He kissed me then ate me out and finally assisted me in losing my virginity to him. While , I was fucking my dad we were caught by my older sister who arrived home to find no one downstairs. She found us and quietly spied on us as she masterbated in the hallway while recording us On her cell phone. While being fucked I saw her behind the door looking at us but i couldn't make out who she was. She then dropped her phone. While trying to retrieve her phone her panties around her ankles caused her to fall and enter the bedroom with a shocked look on her face. After admitting she found the whole thing exciting my father talked her into joining us in the bed
