We called it! The porn star that Twitter made has just signed a big deal with a top studio. Aussie hunk Mathew Mason has joined the ranks of Lucas Entertainment as an exclusive model. Mason drew raves when he posted some nekked pics of himself on Twitter last year. As his following grew, so did the hype as to when this tattooed muscle stud would make his debut. First, he did a group scene for Raging Stallion. But now, Lucas has snatched him up, and his premier scene for them (with veteran star Rafael Carreras) is streaming now and will be featured in Sexclusives, Auditions 45. According to the studio, Mason is versatile and enjoys rimming a tight ass. And speaking of butt... "Mathew has an amazing ass and one of the fattest dicks you will find in the industry," company CEO Michael Lucas says. "He's very dedicated to this industry and definitely has the rare combination of intense sexuality, a gorgeous face and body, and a captivating personality that we look for." Sounds like a winning combo to us. Mason is joined by two new fellow exclusives, Vito Gallo (recent winner as Best Porn Star Escort at the Hookie Awards in NYC) and Tate Ryder.
