So I don't know how this all started in my brain. But nevertheless I was young too young to be adult appropriate but I was gifted a pair of my cousins underwear at a young age I mean he is 1 year and 8 months older than me but I was also very small growing up. The food wouldn't stick

So when I would get his hand me downs there were a few hidden treasures of his underwear was it by mistake...? Was it him that put them in there unbeknownst to my aunt or my mother receiving? Whatever the cause I wore them in secret in the middle of the night as they filled me with a sense of joy and fear.
Fast foward a few years, I stole my first pair of underwear from my aunt's husband (yes, my uncle) but to show lineage. So I usually used the restroom in the common area (Aunt's bedroom was a master bedroom) however in one off chance I had to go and the common RR was occupied. So I was permitted to use hers. I did by business but wondered as there was a laundry basket within 3 feet of me what was there. Sure nuff a pair of my uncles forest green tighty whities . I put them one just under my own pair, I felt like I was wearing a diaper. I walked out of their room nervous, I got in the car nervous, I got home nervous but I was electric. I felt a tingly sensation knowing my adolescent prick was rubbing in the same spot my grown uncles had been. 30 years older than I ~ and I felt like I had bridge the gap. That my dong had went places my uncles had been.
Growing up as a teen with a year or two younger teen brothers. So I use the word brothers loosely because the only brotherly siblings by blood I have are (A.) 4 years older than me and have a different home situation and (B.) slightly more than 4 years older than me and lived in the middle of an ocean. So... my brothers growing up (friends) knew none the wiser of what kink I have and I would sniff their front part of their laundry basket. I would swap out a common pair that I was wearing at the time for one of their not so dirty but dirty pair.
That gents is the beginning.
