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.
