864 sticky fingers

Nathaly Cherie and Victoria Puppy are blowing up two transparent balloons until you can see the moist from her breath inside them.
To increase the moist, they deflate and blow the balloons up again a couple of times.
After playing around with these balloons, they deflate them on the other girls nipple to get them wet too.
Finally both girls take turns in blowing up one more balloon, to mix their spit in it.
To check how wet the balloons have become inside, both girls are sticking their index fingers in the deflated balloon.
