Mike nodded to Anna when she looked on him, when she sucked his bro's cock he focused entirely look Anna on her work. Then, weird to Mike, he started turn on! Of course when he thinked it was his bro and his daugther it made him shiver, but still, shiver does not shake off his hardness which is slowly developing from watching Anna perform blow job to handsome sized cock (in Mike's opinion he and Matt have roughly same sized, altough Mike could say his was 'bit longer and Matt's bit thicker').
