you come into mommys room while she's reading. she notices you and asks why you look upset. reluctantly you tell her you're having a problem with your penis: it's staying stiff.
mommy explains how normal that is and how there are many ways to help with these erections. in fact, mommy can help you right now! she encourages you to stroke yourself with a JOI and eventually even joins in the masturbation on herself with you! she puts on some stepmommy porn for you to enjoy while you play with yourselves. she comments on both you and the movie until you're both able to have an explosive orgasm together!
once you've been relieved, mommy encouragingly let's you know we can do this again any time.
