Being too close can be a problem. These are best friends who reluctantly allow a thigh job—not for erotic purposes, but just to help a friend who looks like he's suffering from a painful erection. They get shy and flustered, angrily insisting that penetration is absolutely forbidden, yet for some reason, their pussies are soaking wet. This leads to "accidents" where the tip slips in and out, and sometimes it goes in all the way to the base. Despite the repeated scoldings, they don't go home and keep rubbing their genitals together. This is true friendship! Four exquisite situations!
