The protrusion 'my own corner' encountered in the office... Office ladies frustrated with sexual desire get excited while hiding from others, rubbing against corners through their stockings and panties! The crotch seam stands out clearly as they are pushed by the hard corner, legs shaking and convulsing in continuous orgasms!! Because I know it's wrong, that's why once you're in, you can't get out. A secret act known only to me...
