I am the head of my branch. I got along pretty well with this colleague in my branch, who seems like a total airhead but is somehow very competent at her job.
1 month ago, I grabbed coffee with her after an external meeting. I have no idea how, but the conversation got to our kinks. I shared mine (smelling and licking armpits), while hers was simply collarbone of guys.
Then, she asked me if her armpits look great to me (in her usual airheaded way). I nodded straight away and said they do. Then, she kept quiet for a few seconds. I took that as a sign to ask the question. I asked if I could smell and lick her armpit. She hesitated for a while, before saying yes.
Since then, I have been meeting up with her everyday to lick and smell her armpit in this secluded corner of our office. I have no idea if she agrees as I am her branch head (I am not that much superior to her actually), or if she genuinely likes the act itself.
Yesterday, while we were doing it in this secluded corner yet again, an intern walked over and caught both of us in the act (we have never been caught even once the past month) . I wanted to speak to her but she walked off straight away. She's 18 and is definitely active on social media. I am afraid if she took photos or videos of us in the act. I have no idea if I should speak to her now.
TL;DR I was caught smelling my colleague's armpit.
