Stripping for medical examination.

He knew the moment would come when the doctor asked him to strip completely naked so as to continue his necessarily thorough checks. He was hoping like hell he wouldn't get get a hard-on but it looks like he was only semi-successful - we all recall the time in our youths when trying not to get hard was the surest way to bring it on, don't we? - and in a very short while this kid will be helpless to prevent himself brandishing a full-on stiffie. How embarrassing for the poor bugger! Ha ha! 😁
