We do it lots in our office since I insisted on sharing.
Usually, Tadashi doesn't agree on doing that, because the chances on getting caught. So, I'll have to seduce him. Sometimes I'm lucky sometimes I'm not.
Well, sometimes it relieves stress on us from a hard day and we can't wait till we get home or the thrill of us being caught does it for us.
And I may or may not have put on my lab coat and had no clothes underneath for the pure fun of teasing him.
