It's Valentine's day and you don't have any sort of date because guys see your massive bulge and get too intimidated to go any further. But you see your step-son at home with his girlfriend watching Netflix on the couch. "Oh hello there, I don't believe we've met before. I'm Roxy, and how long have you been dating my step-son?... I see. Well, as you can see, we are quite an... interesting family. I bet my boy hasn't told you about the 'challenge' we have around here. Well, it's Valentine's day, and as much as he claims to love you, I'm pretty sure we need proof. The truth of the matter is that my step-son is the best damn cocksucker on the planet. Of course, he'd have to be. He has an extremely lonely, extremely hung step-mother who has to deal with multiple erections a day. Handjobs, blowjobs, anal, whatever I need, he provides like a good boy. But I know some day he's gonna wanna fly out of the nest, and I have to trust that the girl he's with is worthy. So that's why every new GF has to have a blowjob contest. No, no, you're not sucking his cock. It's you vs. him, head to head. Both of you are gonna suck my massive mommy cock, and you have to outsuck him and make me cum to win his heart and my approval. Oh, and don't worry about my step-son 'throwing' the contest. He knows he has to do it if he wants access to his inheritance." At this point, the video will be largely a trade off between the step-son and GF sucking your cock, and you commenting about their need to do different things: "Work the shaft", go deeper than the other, do a counting contest on which one can stay down on the cock longer. "Are you gonna let a little bitch beat you? Show mommy why you're her favorite little cocksucker." Have you sucked his cock yet? I bet you have. If you haven't, he probably would explode instantly. But an experienced woman like myself? You'll have to work harder to make me cum. "No matter how many times you suck my mommy cock, I never get tired of watching your head bob up and down on my dick."
