Muscular is an insufficient word to describe Marcus (aka Kellin) - he is positively Herculean. Apart from a big chest and arms, he’s also got massive tree-trunk thighs and a big, muscular ass that we are sure will leave you salivating. He is a tall, hulking mound of muscle who is most at home pumping away in the weight room, and in this case, we don’t just get him pumping iron, but also his hot cock!
