You are watching tv with your son (neither of you had established/had any sexual feeling for each either) while waiting for your husband to get home so you guys can go to family dinner. (You guys could discuss that things are going well with his girlfriend/ you and your husband are thinking about having another babee soon, and casually slip up that you and him are trying for one tonight, then apologize for saying the last part) Suddenly, someone breaks in, and not having any valuables in sight, the robber goes for a show instead. The robber begins by making you and your son (the camera, for POV purpose) kiss. It doesn’t take long for the kissing to accelerate into more commands from the robber for both of you to strip naked where you are instantly aroused at the sight of your sons hard cock for you. The robber has you give him slow head for about 10 seconds, and then says it’s not sloppy and messy enough.(body doll) You then suck the soul outta your son in front of that robber. (as sloppily as you will go please, I love when it’s drenched in slobber) (also eye contact if possible) He then has your son devour your vagina, swiftly adding fingers to his task. By this point you are both into it, with you moving your body and showing off your massive breasts. You are leading the way on accepting the commands from the robber.(POV style) He then has you guys have (missionary POV) sex. You rub your breasts and play with them to help your son speed up the process when you notice your son looking down more. He is in awe of your beautiful stomach. You notice that he has a belly fetish; turning you both on even more when the robber notices as well and calls him out for it. (I would love for you to jiggle your stomach and emphasize it moving for this part of the scene please, if you get sweaty it’s even better!) After missionary the robber then wants to see you and your son in reverse cowgirl where they both just want to see you twerk and shake your ass as much as possible, the more jiggle the better for everyone! It ends with a ride on the torso machine with you facing the camera. The robber instructs your son to cum inside you; you are struck back to reality. You slow down for a second. You ask him to allow him to cum on your stomach because you are fertilizing, but he says no. You get back into it after realizing that your son is now throbbing inside your pussy. You say something like “Do you want to cum in mmomy sweety? I felt you get harder” As you begin shaking your stomach and breasts more vigorously. You ride for a short while longer while using your hands you move your stomach up and down. You say something on the lines of “Tell me I have the best pussy in the world” and when he responds that you in-fact do, you both cum; him exploding inside of you. The robber runs out as your husband returns home. He doesn’t believe a word. (Alt end if not acceptable) Once you both cum, the robber reveals he is the father. (Mmom knew)
