I have read other techniques here, but I have not seen mine yet.
Call me weird, but I just love the smell of used panties and used socks. They just turn me on real good.
So after I get home from school, I usually go upstairs into my room, lock the door, and finish my homework. Then I eat dinner with my parents. After that, the fun starts.
I go back upstairs, lock the door again and turn some music up loud so no one can hear me moaning. Then I take my jeans off and with my panties and dirty socks still on, I slip two fingers into my pussy and just start going. When I cum, I just try to keep that cum inside my panties so my pussy is still touching it. If there's not much, I go again. After once or twice, cum will be leaking out, but I don't care. I just lie there and go to sleep in my wet panties and dirty socks. I clean up as soon as I wake up the next day. However, if it's the weekend, I just take a quick shower and put back on the panties and socks for the duration of the weekend.
So if used panties and dirty socks are for you, then by all means do it with them on.
