<human>: So today I was running late for work at my Government IT office job so I just decided to go commando and put on the only slacks and polo I have that aren't very wrinkly and get out of the door.  I don't usually boast but, I'm a pretty well endowed guy. I'm kinda out of shape but not a bad looking. Well, typically I get kind of aroused in the mornings; It's just my time of day for when I'm ready to rumble. So I get to work and I'm checking my email for a while and the fabric of my slacks just rubbed me the right way and I involuntarily got kind of aroused. So I decided I'm gonna get up to walk it off and go grab some coffee downstairs. 
Here's where IFU... As soon as I walk out of my office my beautiful 5'3 and maybe 43 years old female HR manager walks by and says HELLO! and gives me the up down from head to toe and stares for a few seconds at my crotch... I catch a sight of her lacy bra between the buttons of her partially open sheer button up blouse and she looks up from staring at my crotch with a smile on her face and catches me staring at her chest and that's when a disgusted look comes over her face. She speeds up and walks away to my IT managers office.
She's been acting funny towards me the rest of the day... I don't even know how to react at this point.
