Well I'm sure someone, somewhere is getting horny doing this...folks get off on all sorts, it just makes us interesting. Not my thing though. S x
The way its phrased, it sounds like it would be more distracting than enhancing. What exactly are we taking about, a couple inentionaly spitting on each other? a couple who drool a lot? or a natural source for lubricant to lubricate that which benefits from lubrication? Does it enhance the OP's orgasms? or their partners?
