Hom Strangling With Two Sis

The two sis Jane and Layla today want to take the breath of their servant away. He isnt to breathe when he wants it, but only when those two want him to breathe. So they are pressing shut his mouth and his nose with their forearms. How long will he be able to stand it?The two sis will find out; and he can only hope for some air soon. Against four palms on his mouth and nose he doesnt stand a chance!
