^never saw one of those.
Someone explained it to me once.
You have these guys who leave home for work.......they find themselves alone and want to make the best of their privacy; however they don't want the PPV porn charges to get back to their workplace; and they are too timid/faithful to call a hooker.
So they buy porn magazines and have a little "party".
Of course they can not take the material home (their fat and psychopathic wifes would thrash them within inches of their lives).......but they also are prudish enough to be bothered by the thought of the cleaning woman finding the stuff in the trash can.
So they stick it under the mattress and leave.
