Sexy Stepmother submitted this to you as an video for your edification - Sexy Stepmom teaches them to ask for it.

(I am not making this up - it's actually what our mothers used to do to us.) So, how does a step mother teach her teenaged step-children how to get it? The beautiful thing is... they get it from each other..
