I'm your son & you're a bimbo. Your husband has convinced you if a man has an erection he must cum inside a woman or he'll get seriously ill (as he's a loser and it's the only way you'd want his small cock, basically). You come to wake me up one morning and I have morning wood, which you panic about and insist on taking care of me. I'm just kind of reluctant because I don't really know what's going on but you're my Mom and such, but you're very insistent you have to help me. Also midway through Dad comes home and catches us, but you're not ashamed just proud you discovered my issue and are helping to make sure I'm okay - and then for fun I'm also much larger than him and you talk about how much better I am and such and cuck my Dad/your husband in fromt of me. Also can talk about the size of my balls and how I'll surely knock you up. You suck me off and ride my cock all the time making my cuckold Dad watch and humiliate him.
