I caught my stepsister masturbating and helped her cum twice

I go to my fat stepsister's bedroom and see her touching herself with her sex toy. I put my cock in her mouth and she began to suck it hard, I started fucking her in a missionary position while she masturbated with her toy, she couldn't take it anymore and she came. Then I start fucking doggy style and when she can't take it anymore she gets back into missionary position and cums a second time. This chubby girl is a slut, I hope I can fuck her more times...
