La piccola sorellastra voleva che le insegnassi il sesso

I have a hot brunette stepsister, whom I thought was a very innocent girl, but I was wrong. She is a very naught teen who not only wants big dicks in her, but she also love girls. One day, I was in bed with her when she started touching me and asked me if I could teach her about masturbation and sex. Soon we both were licking each other's cunt and having orgasms.
