That got your attention.
If you ever see images of a couple having sex on a ladder, don't trust them.
With the way most ladders are built, the only way those photos were taken without the models breaking bones is by posing. No actual love making or hot action. They woulc have to be completely motionless or otherwise the whole erotic affair would end up a pile of naked body parts and bent aluminum.
Either that, or they lead such a boring sex life that they don't actually disturb the balance of the ladder. In that case, the ladder is just there to make you think they are kinkier than they are.
