After over five years in the booty biz, experienced Dominican and Irish porn star Donny Sins has three pieces of advice for guys looking to cum up in porn stardom: "1. Stop running your mouth on set 2. Keep your dick hard on set 3. Learn the business." Those tenets have certainly worked well for Donny... and having a massive black cock has helped too! In fact, you may have spotted Donny's very large and recognizable member in a prestige TV series during a locker room scene, a sight which no doubt led millions of American women to seek out some Sins.
