posing mod works too*

 

edit: my goal is to take screenshots of the followers kissing (without them getting naked if can)

There are many mods that can do that. I use Puppet Master. More commonly used is SexLab Matchmaker. There are also many others most of whom cause that to happen organically as part of the game.
