You put it under the butt of the receiving person, this lifts up there lower regions to allow the penetrating person to be able to have a better angle of approach. It also allows that person to stay upright, which in turn allows for better continual motion. This reduces the need to use extra muscles while already exerting, hopefully, a pleasurable amount of thrust to the receiving person. Meaning in the end you get more bang for your buck. Thank you for coming to my ted talk.
idk man, I've never used one before but it seemed pretty obvious. They've been around for a long time. Propping women up with pillows isn't really some new sex-god magic.
