When young, you know that age where you understand that playing with you cock is nice and that other boys makes you feel something, I used to borrow other guys underwear to jerk with when they hit the showers after the gym in school.
One day most of the guys where done showering when I was done so I couldn't put the used underwear back. Instead I put them in my pocket and had to bring them back home.
That night I was thinking alot about the used black briefs that I hid way back in my closet and after a while I took them out.
I sat there, half naked on my bed with this guys used gym underwear in my hands. I still don't know why but I put my face where his cock used to be and started sniffing.
The smell was still intence and made my really horny.
I started to jerk while smelling his underwear and soon I was jerking with his used underwear.
I liked the feeling of his underwear against my cock but I also liked the smell they had.
Soon I felt this urge to sniff his underwear at the same time as I jerked with his used underwear.
So, the next week I stole another pair. Navy blue briefs.
Now I could sniff his cock at the same time as I felt him against my horny cock.
After a couple of weeks I started to fantasize about sniffing another of the hot guys underwear so I stole a pair of his. Then I stole another pair so I had some alternative. Sniff guys A's cock and jerk with guy B's, sniff guys B's cock and jer with guy A's, sniff and jerk with guy A's or guys B's...
This really got out of hands.
When I was 18 I had 58 pairs of underwear but all of them got lost when moving
I decided that was it. I couldn't do it anymore.
Then one day a friend asked me to help him with his computer. I followed him back to his place and started to help him with the computer.
After a while he said he needed to take a shower and asked if it would be ok to leave me.
I said yes and he started to undress in the only room that was his apartment exept for the bathroom and I mean TOTALY undress.
When I heard that he was standing in the shower I looked over to the pile of cltohes he left behind and at the top was a pair of white, tight boxers.
I picked them up and they where still warm from his naked body.
I started to sniff them and got so horny.
I went to his closet to try and find a pair of underwear I could jerk with. When I opened the closet door I found a pair of white boxers that looked the same as those I couldn't stop sniffing. I put the back on top of his clothes and took another pair to jerk with.
Before I was done he turned the shower of and in the panic I put both of his underwear in the bag I brought.
Now there was no turning back.
Now I have 122 pairs of underwear from other guys (not including those 58 I lost) and I always check for more when visiting frindes.
17 of these are from a former room mate that alwayes jerked after he went to bed and usually used his underwear as a cum rag.
