Come out of your revery, but don't cum.
You see that I've changed clothes. I thought I'd give you a little taste of my talents.
While you're stroking your cock with your spit, use some spit to really lube up the index finger of your other hand and when you think it's wet enough, stick it in your ass as far as you can. Feel free to pre-lube your asshole with your spit or some real lube before inserting your finger.
Once your finger is in there, start sawing it in and out.
Very nice, I like boys who can take it up the ass!
