While watching a movie, my best friend who I had a crush on fell asleep. He sprawled out on the couch next to me and put his feet on my lap/crotch. Sometimes he would shift around, so his feet would rub against me. He had low cut black Converse socks and the smell was an intoxicating/irresistible combination of both fresh, clean, but musky. The aroma, touching, and occasional movement made me go wild as someone who at the time never had been in any relationship. I'm not usually super into feet/socks but I was definitely hard for the rest of the night.

Not sure if that counts as playing, haha. While pretty high, I did once poke at his toes and hands because I thought they were amazingly weird and stubby in the moment.. He was pretty cool with it.
