I've been cumming in my mother in-laws mashed potato for years now, we have been living with the in-laws for a few years and as i always finish work first I'm the one assigned to cooking the dinner she was always not happy about something, the meat is overcooked or the veggies are undercooked, i just snapped one day and thought Fuk you bitch I'll just add some special sauce to your mash and now she actually compliments me on how good it tastes. I usually dangle my balls and rub my knob around inside her tea cup before she gets home too. Now I just smile as she sits there eating her mash and has her cuppa after dinner, I'm trying to think of other ways to feed her my cum.
