Blow jobs with added
spice. You'll need
mouthwash,
altoids, something with a
minty or
cinnamon tingle to it. Planning is
everything.
Put a small amount of the mouthwash or an altoid in your mouth. As you go down on your partner, release the mouthwash slowly so it drips down his
shaft, or use your
tongue to slide the altoid along it. The resultant tingly sensation can be quite interesting, and it will
freshen your
breath, um, later.
I have also read the suggestion of smearing toothpaste on your lover's testicles to lick off later, but I'm a little more dubious of that one.
