While looking at porn or reading the great Solo Touch stories, I like to edge for ages. I find my mouth watering all the time, and recently I've been putting it to good use.
I get a clean glass and regularly spit a mouthful of saliva into it as I'm playing and edging.
The slippery liquid quickly builds up in amount, and also gets cold in the glass. Every now and then I dip a finger in and rub my nipples with it. It's so slippery and cool, it really gets me going.
My mouth waters even more and I add more juice to the glass. As I get nearer to cumming there are a couple of different tricks to try. I can just start pouring the glass over my hands and cock. Wow - that feels so slick and sexy.
Or, I slurp a big mouthful and swill it around to warm it up before either dribbling it down my chest and onto my cock - so decadent and dirty, or just spitting it directly all over the shaft as i rub. Just as I'm about to cum, I make sure I have another final load of the slippy liquid to lube my cock and balls, and sometimes I position the empty glass to catch my cum and I have a drink of the fresh salty liquid to finish.
I do this naked and sitting on a towel, so easy to clean up after. Great fun, totally free, all natural, and very dirty and sexy.
