Up to 1/3 of the eyecandy involved with getting a good blowjob is how the spit looks, of course that can vary depending on how good (or bad?) the female in question is... if there is an awesome performance going on around my dick I have been known to overlook how hot the spit can be. Anyhow, if you have ever really put your dick down a girls throat and then pulled it back out quickly you have probably seen the thick white spit (wayyy different that regular clear 'from her mouth' spit)... that you can only get if you touch the back of her throat with your dick. Works best if you're standing over her... If she isn't tied I demand she keep her hands to her side while I do this-- since it causes them to gag and nearly vomit they will tend to grab you and stop you from moving forward-- do not allow this. The gagging sound can be very hot... more often than not... but when you pull back out of her mouth and see the thick white strand of spit... almost as thick as cum, and she looks up at you with tears in her eyes only to close her mouth a little to moisten her throat-- without breaking eye contact... I love that.
