Sleepy tickles is a guilty pleasure of mine.
I've done it a few times to a friend of mine on the rare occasion that he's either spent the night or taken an unexpected nap on the couch. Bare feet are the best; I've used both my fingers and sometimes a feather to make his feet twitch. Thankfully...
Long time lurker wanted to share a story. I am what you would call a 'ler that is strictly into M/M and I've enjoyed tickling for as long as I can remember though I've generally kept much of this interest to myself.
Anyways...
My closest (I guess best) friend, whom I'll call "P" is very tall...
A friend of mine has non-ticklish feet however I've tickled his bare feet while he was asleep with feathers have gotten some toe wiggling and twitching.
