I (m, 56 yo) work as a janitor and work mostly at night in an office. I start at 9 pm and make round around the empty premises, look into unlocked rooms like washrooms etc. The female toilets always attract me and brings in me h**** thoughts. I often get interesting objects in the trash bin. Hair clips, discarded cosmetics, sanitary pads, tampon of various sizes, used condoms, bra with torn straps and lots of used panties. Most common are the soiled panties that I love to sniff and lick at regular basis and m********* wrapping them around my c***. Few times, I have come across used tampons, some fresh others older with bad odor! I look for fresh ones with some blood, slime and still slippery. I smell them, reach a good hard-on, often lick on them and suck for few moments and m*********. Later I push one used into my a***. I leave it inside me for the rest of the night, take some used panties to m********* again when I return home. Feels good!!
