Nelly and Lili versus the double ballgag
The double ballgag is one of the hardest and most annoying things you can imagine. You’re gagged, you can’t take it off, and to make things worse, you are connected to someone you thought was a friend. Well, no matter how close you are as friends, a double ballgag will always cause some irritation. You feel every single slight movement of your friend. Why can’t she just sit still? Why is she drooling all over you? It’s so hard to be in this predicament! Poor Nelly and Lili!
