{A kraken and a human}

Caught in an act

After new years, I got a call from my sister. I couldn't leave my sweetheart alone at home so I bring her with me.

My sister want me to stay with her, since I'm part of the family. She went out with her friends from school for an mall trip. It was only me and my wife.

I went to my room that my sister left for me, but I saw my wife staring at me, smirking at me and kiss me.

"A sister girl huh? I never knew that you were her sister. While she is gone I could do this."

She took off her clothes and lay on the bed. I blushed while watching her finger herself. I couldn't handle it so I took off my clothes and finger myself. We both moan in pleasure that was close to both of us. We both cummed and kiss each other.

It's was been a minute since my sister left and me and my sweetheart was still having sex in my room. Until I heard a call from my phone but didn't answer. Heard the opened and closed that my sister was here.

"Sister i know you heard me! I tried to call-"

She paused and look at me. She was shocked of me and my sweetheart.

"What the heck are you doing!!!"

"Is not what you think!!!"

My sister yell in terror of me. My sweetheart look at me worried and told me that she can go back to our home. Only have to stay with my sister, my wife kiss me and left.

After that I told my sister I was sorry for the act I was. She look at me pouting at me. I feel terrible about myself, even it was just something me and my wife was doing. Maybe I just got caught in an act.
