You can definitely see why your father married your mother: she's a total babe, even now! But an intellectual giant she is not. Your father always jokes about it to you, telling you that she's got no brain but gives great head! You've always wondered what that would be like, and wondered as well whether her lack of intellect would make her susceptible to a little persuasive conversation. Not coercion, so to speak, but capitalizing on her lack of knowledge, just to see how far you can get...so, one day when you're getting over a cold, you decide to try it when she comes to check on you. You've got a raging morning boner and she can tell - a perfect setup! You tell her how sometimes you get sick when you don't have someone to relieve you...you can see the cogs slowly turning. She says no at first, she couldn't possibly do that! You're her son! But you persist, telling her its dangerous to get this backed up, that it won't really be sexual - just therapeutic! She eventually buys it, pulling back the covers and immediately using her mouth! Your shocked, assuming the most you'd get today would be a handjob! She looks embarassed, explaining that she always gets your father off this way while you tell her it's totally fine, please, go right ahead!! Her mouth feels amazing, and it doesn't take long before you can tell she's getting turned on herself. So turned on, in fact, that you don't even have to suggest she speed things up with her wet, hungry pussy, which she is discreetly fingering while she sucks her own son's cock! She climbs on top of you, leaning back and riding you cowgirl until you spill your seed deep inside the very same hole you came out of
