My fantasy
For context: Im from germany and tighty whities arent common over here. They are even hard to get. I realized i had a huge fetish for them when i was 18 / 19.
One of my biggest wishes/ fantasies back then was to be forced to wear them. I thought about getting into an exchange program and travel to the us for some time, yet never applied for it. My fantasy was always to get to a dad who had a zero tollerance policy for boxers and tight boxers. He would make me chop up all my underwear and then would take me commando for a shopping trip. He would make me buy high waist tighty whities, white crew socks and a white tank top. And at home i would only be allowed to walk around in underwear.
Ofc he would make me suck him off daily, or even uses my ass. Perhaps even a chastity cage.
