In 2011 Matthias von Fistenberg went to Rio de Janeiro and discovered some of the biggest-dicked Brazilian Tops and tattooed guy bottoms south of the equator. What came was the birth of one of the most popular series in the Raw Fuck Club franchise, A Monster Inside Me. Now, Matthias has gone back to Rio for what makes the 4th installment in that franchise. Monster 4: Return to Rio features 5 scenes, 7 models, a 4 way orgy, and yeah, mega-inches of raw-fucking Brazilian meat. Lube up nice — your need to need it for those Monsters.
