Step-mummy teaches you about erections and masturbation

Description: I come back from having a shower and find you in the living room looking confused, and sporting a very stiff erection. you have no idea what to do with it, so i step in and gently explain about what causes an erection and how to deal with it. i also explain the differences between males and females and show you how i masturbate while i encourage you to wank and have an orgasm.
