I have used an Eggplant but more of an 8 shape. Nice and big and it is smooth and slippery. I did love the feeling of it as it stretched my faggot hole. Try a Butternut Pumpkin.
You are awesome and Dr. Nek is an incredible asshole wrecker. Love him to do my faggot hole esp with his long black dildo. I didn't think you would get that purple vegetable out once he got it in your hole. Was it an eggplant?
