Do the model couples shown in hardcore smut mags actually fuck?

Or do they just pose in different coital positions while the photographer snaps away? Are they even allowed to screw? How does a hardcore photoshoot work?

 

Usually its just poses without penetration. A male model doing just a photoshoot has no need to keep an erection plus he really can't over the long hours required to get the various and many angles needed to put together the layout. If there are close ups of cock in pussy then yes at that time the two are connected. But they usually don't fuck. They just hold the pose for however long it takes to get the needed shots. Then it's on to the next set of poses. The camera angles make it seem so though. If the two do find a connection, which a lot do, they wait for a later time to explore it. When the cameras are off instead of going by a script or predetermined poses they just wing it and fuck like the rest of us do.
