Whats with yaoi and feet/armpits???

its whatever you're reading because this is the first foot fetishism ive seen

Then you must be new here ,hi

ive been on this site for 6 years and have been reading yaoi for over a decade my dude. this is one of the first times ive seen a character give a footjob. its definitely not commonplace unless youve somehow been lucky/unlucky enough to stumble upon it, depending upon your perspective x)
