Every time you are around me I can tell you have a massive boner. This is starting to be a problem I'm your step-mom and I want us to figure this out together. What can we do? maybe if I let you jerk off to me you will just get it all out of your system. Should we at least try that? I don't know what else to do and your hard cock is just unacceptable. So take out your cock for me and start pumping. This has got to be our little secret ok?
