On your break while talking to your co-workers, one of them bumps into you and makes you spill your coffee over you, the co-worker apologises a lot but is clearly in a hurry and you say it is no problem. the co-worker in hurry scurries off. You drink up what is left off the coffee in the cup dry your self up with napkins and proceed to the toilets.
You have two cheap paper cups as you take two cups to deal with the heat of the coffee itself. You go into a stall and get the stained shirt off. You are now sitting on a closed toilet with you upper body only clothed with a bra. You give a small chuckle and unclasp your bra and put the two cups around where your nipples are. You feel your nipples fill the cups. You already feel a bit of euphoria as your nipples touch the cups. You remove the cups to unveil two almost grotesque nipple on top of your C cups.
Your breathing gets a slower as you feel a slight arousal combined with fascination. You circle around you nipples, slowly slowly approaching it. As you touch them, you shiver, you inhale slightly and slowly, circling upwards. you tense up completely as you reach the tips.
You are aroused.
You need to calm down. you cant do this at work.
You try to tuck in you nipples, you succeed, but at the cost of a small moan, you hope no one heard.
As a slight twist of fate there is a slight outline of your nipples left from you little experiment, it is not noticeable so you should be fine, maybe when you calm down a bit more they will disappear.
You exit the cabin and attempt to remove the stain a bit more and continue working.
