OO0h the possibilities...
I am hungry right now so you should play with some food. Cock resting on the table/counter as you prepare a meal. Be careful with the knife! but chop your food up next to your soft cock. Wear heels and a short nighty like a good little slut should while cooking. Start touching yourself and rubbing your cock all over the food until hard. Stroke with food in your hands, rub your balls all over the food, them cum in the prepared dish (if allowed) and eat it; enjoying the taste of your cock, balls and hopefully cum - you know you want it all in your mouth like a greedy suck slut.
Thank you @marysweet! Your suggestion is very special. So special that I was really turned on by the idea. I never played with food. My mistress decided for another suggestion but there is a high chance that she orders me to do something similar to your idea in the future. Thanks for giving this idea :)
