Mom's been helping you to release as part of a doctor-ordered course of treatment. Before bed, before a big test, after a date...any time I think I might need it. It started out more clinical, but now she seems to be kinda..into it? She even let me fuck her tits this time. I've always wondered what that would feel like, and seeing my cock slide between my mom's big natural tits makes me cum so hard, I cover her with my load!
