Justyne does what she does best. Sucking dick and blowing up a balloon. And because that's pretty wicked, it doesn't take long until you cum in Justyne's mouth. Now she has to blow up the balloon with cum all over her lips. And that's not so easy, because the balloon slips out of her mouth again and again. So she can't do a b2p anymore, but she can bite it.
NOTE: This is the edited scene, that you may have already seen in "Justynes Shootingday" documentary.
