These all look like amateur snap shots taken at home or in a motel room. It is unclear how these shots were taken, but most cameras used to have timers. You set the time for as long as possible and then rushed back to pose before the shutter snapped the picture. This may not have worked here when you also had to place a young lady across your lap. So I don’t know how these pictures were taken absent a friend in the room to help.
One other possibility is that these are all screenshots from videos. In which case you just let the camera run unattended with no need to run back before the timer took the shot.
