The latest development from Professor Cowboy's stem cell cloning research institute (now banned - as all good things are). He was trying to make cows' udders produce more milk, but his undergraduate assistant Rush accidentally injected the cloning mixture into his own bottom (being prone to such practices already).
Rush now has two huge milk producing jugs on his slight torso. Well, in for a penny (that's all he ever got), he became a cute ultra-sexy ladyboy, dripping with gone-astray-hormones.
Professor Cowboy immediately dropped to his knees to examine Rush's cock, knowing that with the correct stem cell therapy (and plenty of saliva), that too could swell and produce milk (of a kind). Catch all the heavenly research on video.
