Once I stayed in a youth hostel, and shared the room with a few other people, one of whom was a well spoken, good looking Japanese man in his 20's.
I woke up late the next morning, and by then, everyone had gone out for the day. The Japanese man's bunk was next to mine, and I saw in a corner his pile of dirty clothes. On top of that pile was a pair of pink briefs, and they were very brief indeed, made of some synthetic material.
Its shiny pink colour practically called to me like the Sirens. I was lured to them, lulled into a state of imagined serenity and safety, oblivious to the danger of being caught in an embarrassing position.
Even though I was the only one in the room, I slowly and stealthily crept towards that small shiny piece of intimate clothing and sniffed - no, inhaled, actually. The Japanese young man's odor was ripe and almost sharp; I cannot help but wonder how many days he had been wearing that same pair of briefs, and what he had been doing while wearing them to result in such a strong, agreeable pungence.
Perhaps it was the sense of disgust with my own action, that invasion of the young man's privacy, the fear of being caught, the humiliation if caught, all these emotions made me so horny! I did not move his underwear in case his suspicions are raised, so I had to content with the smell from a couple of deep inhalations. Yes, once was not enough, I had to take a few deep breaths of his balls bouquet, of his scrotal stink.
Having stored his smell in my memory and filled my lungs with his scent laden air, I removed myself back to my bunk and shamelessly jacked off, my whole body uncovered and exposed. By now I was oblivious to the world, and had no fear of humiliation and indignity of being caught masturbating.
Being uncut, I have no need for lubrication; a few pumps to the recollection of that scent in my mind, of the shine on the pink briefs and I started expelling my man juice all over my body. After a few spasms, my rigid body relaxed and I did not want to make any move to hide the evidence of my solitary enjoyment. I had no fear of the cleaner coming in to catch me red handed - or should be be cum handed - all I wanted to do was to savour the afterglow of a great climax.
When effects of the dopamine, serotonin and oxytocin finally abated, I was thankful no one had entered the room to find me in flagrante delicto. And I shall live to sniff another pair of underwear another day!
