Custom I come round to hang out with your son, but notice you are sunbathing. I get hard looking at your body in a bikini and can't help myself that I go to the toilet to jerk off over you. You catch me in the toilet with my dick out and hard, and you know that I've been stroking it while thinking about you. You ask me haven't I already had enough wanks over you? You like having this power over me, at how weak I get over your body so you close the door and get your nipples out and tell me that you know I'ver been dying to see your big fat nipples again. You tell me to stroke it while I stare at them because this will be the last time you will show me. You say you can't do this anymore otherwise we'd likely get caught and all the other moms will find out you're a slut who likes making guys moan over you. You tell me to hurry up and cum because your husband is downstairs and you don't want him to find out that you're a slut who lets guys jerk off over you. You can see I'm excited from the precum coming out of my dick and you tell me jerk faster cos I'm nearly there. Then you say you're going to give me more encouragement and so you get down in that squatting position, tits out and legs spread wide. You tell me to jerk it for this pussy, to stare at it and jerk it for your pussy. Again, like last time, you tell me not to make a mess and to stick just the tip of my dick into you when I cum. When I try to have sex with you, you tell me off and say I'm not allowed. That I can only jerk off over you.
