Our family has suffered generations having overdeveloped genitals, you a big ass and busty body and your son huge cock and balls. You and your young son are on vacation at a hotel. Your son wasn't feeling good so you took him to a doctor who ran some tests and then called you back with the results while you both were already back in the hotel room. Your shocked to hear that your son even at his age suffers with having huge semen back up because of his huge balls and that you will have to help him relieve himself because he doesn't know how to himself. You are shocked but realize there is no other way. So you wear tight yoga pants and decide you don't want to touch his cock so you will use your ass. You call your son into your room and have him lie down you then tell him that the doctor called and has instructed you on how to make him feel better. You have him strip naked and tell him not to worry this is all to help make him feel better. And get on top of him and start grinding on is cock. All the while you reassure him and start to talk dirty. After a bit you turn around and grind on him with your ass facing his face, your ass cheeks jerking off his cock, and suddenly feel his huge cock rock hard. You look back and see he is transfixed by your big ass. You smile and say is that what you like mommas big ass. He starts grunting and telling you to get off and that he is going to pee, but you are to into it yourself turned on by his huge cock. He repeatedly tells you to get off and that he can't hold it but you don't get off. And tell him to let it all out for mommy and more similar things, and that breaks him. He starts grunting and explodes all the while you are using your big ass to jerk him off. Cum rains everywhere all over your big ass and him all the while you edge him on. Finally when he stops humming you realize he is still rock hard. You are to turned on to stop. You take off your yoga pants and top completely nude, and rub baby oil all over your ass and body, and his big cock. And start grinding on his cock again your ass facing his face. You big ass cheeks engulfing his cock and jacking him off. You talk really dirty the whole time about how he loves his momma booty and similar things. He tells you he is going to explode again. This time you move forward and start twerking your ass cheeks for him one at a time ( its ending a short video of what I mean by one at time) and edge him on telling him to show momma how much he can shoot for her, and to spray all over mommas big ass, and more. He stands behind you is in an angle where he is above you so that only your big ass cheeks are visible not your ass hole or vagina. And he starts cumming a huge amount all over your big ass cheeks while you twerk and encourage him. This cumshot last like 20 seconds at least endless cum shots on your ass cheeks while you talk dirty.
