What’s a cup? I believe that the students who can ask this question must not be “veteran drivers”, but a just adult, with the curiosity and desire for both sexes, the first time into the world of adults “children” ~ airplane cup this thing, in fact, is a male masturbation tool. A tool, its shape and texture can be said to be very similar to the female vagina. When a single man is in physical need, this thing can be their best “sex partner”. But then again, even if the plane cup this thing how realistic, as long as men use him to solve their needs, it is still considered masturbation. And masturbation, it will make people addicted.
