I walk into my step-sons room and catch him jerking off. I apologize and start to explain why I was in his room and realize he has not stopped jerking it! To be honest I can’t take my eyes off him doing it and start to get turned on. I take my dress off and start rubbing my pussy. I know what I’m doing is wrong but still I walk to my step-sons bed and take his cock in my mouth. I tell him what we are doing is wrong but he doesn’t seems to care at all so I keep going till he erupts in my mouth!
