The art of enjoying taking in the aroma of a females dirty crotch scent contained in her soiled pantys. Held close to the nose and with a slow, deep inhaling of her soiled scent. Licking the filthy panel can also give a tangy taste. Most usually performed whiled masturbating with a towel on your chest and your cock well lubed with ky jelly.
I layed back on my bed, towel on my stomach and a handfull of lube. Stuck the filthy, pungent crotch of her soiled panties to my nose and inhaled the aroma of her 3 days long worn deposit. It was so strong my brain couldn't take the treatment any more from her female scent and offered up my bounty of man goo, spewing from my cock. panty sniffing again helped me to bust a much needed nut, joyously.
