SSNI-885 Secretly having sex with your lover's sister

There's no way this will happen. Her younger sister Lena came to visit the house where I lived with her. The next day she went on a business trip for three days, very soon she came back and she said. I'm lonely so I'm with you. It was very hot that day and we were sweating, but our sexual desire was unusually strong. I couldn't bear it anymore, I finally made a mistake with her, a forbidden physical relationship that started from morning to night, as if swallowed by her desire.
