I have stretched my ass many times. I have found that a nice round potato works best. I find one and put a condom on it. Lube it and my ass . I now have 3 sizes. I slowly stretch my ass. Today I finally bot the largest potato to slide deep into my ass. It felt amazing. I am now ready for someone to gently try to get their fist inside my ass! I really want it!.
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.
