Bitten A Venomous Mommy & Son Story

Mom freaks out when she sees a big ole nasty spider! You run to help her and she begs you to get rid of it, but in the process, it climbs up your leg and bites you! You quickly start to feel weird and mom panics! Surely it must be poisonous! She considers calling for an ambulance, but is worried it won't get here in time. Maybe she should suck the venom out of you?! You tell her it bit you on the tip of your dick, and not only do you feel weird, but the venom made your cock swell up to 3x its normal size! Mom is unsure of what to do and hesitates, but as you seem to be getting worse by the second, she knows she has to suck the venom out of your cock! She sucks your gigantic, swollen cock and gets the venom out. And obviously your cum. Almost instantly, mom starts to feel weird. The venom must have gotten into her through her nipples when she rubbed your venom infused cum on her breasts by accident! Mom begs you to suck on her tits to get the venom out, but it doesn't work. The venom works it's way through her veins and turns her into a cock crazed wild beast!
