My 18 Year Old Sister-in-law Smokes and Seduces Me

My wife is at work and her little stepsister is sitting on the couch telling me she tried to have sex last night but was too inexperienced. Not one to miss such a great opportunity I agreed to teach her. Jessie lit up her VS120mm cigarette and posed for me. I got Jessie over to the bed and slowly put a couple of fingers into her wet pussy and finger banged her. Jessie said she wanted to suck my cock. Her mouth felt so warm as she slowly stroked and sucked it. I turned her onto her back and started to fuck her. We fucked like crazy with her on top of me and me doing her doggie style. She even lit up another cigarette and smoked while she rode my cock. I rolled her onto her back and fucked her mouth until I dumped a big load of my cum into it.
