when I was in high school, I bought a maybe 1 or 1.5 inch diameter candle and carved it into a dildo, haha. worked great, until one day I got overly ambitious and tried to drill a hole down the center so it could cum in my ass, and it broke
when I got my first debit card, the first thing I did was go online and buy myself a real dildo. my favorite one I ever had was the Gia Darling futurotic dong
it's based on a mold of gia darling's beautiful cock. trust me, after trying that thing, household objects could never satisfy again. its not just solid rubber, the 'skin' is a different material from the core, so its softer, and moves a little independently from the inside, much more realistic. alas, I had to throw it away when I went off to college, didn't want to worry about that getting discovered by nosy floormates, haha
