A bildo is an anal dildo. Sometimes referred to as a bulldo/buldo. Known within many gay communities as a billy (slang).
Josh loves to bully himself around with "Andy" his favorite bildo. Sophia likes to help me masturbate. She will use a bildo on me while I wrap my fist around my cock and play with my balls. As I get close to coming, she thrusts the bildo harder into my ass. My climax is mind blowing.
Knock knock....
Amy: You home Bill?
Bill: Oh hi Amy what can I get you? A cup of sugar?
Amy: Ummmmm just wanted to know if I could borrow your Bildo
Bill: OK no worries, I have a pie in the oven so you can only borrow it for about 10 mins
Josh opened his tool box yesterday and there was a bildo inside. He blushed and slammed the lid, ashamed of his obsession with bildoing himself in the porto potty at lunch time.
