The easiest to generate is skirt/dress lift : skirt lift or dress lift , lifted by another , hands . And you can add looking back , or from behind or ass , to generate a view from behind.

For the rest you can try a combination of the following tags:

• Pulling: clothes pull, panties pull, shirt pull, pants pull, bra pull , etc.

• Lifting: clothes lift, shirt lift, sweater lift, bra lift , etc.

• Useful to add (one or more): pulled by another, lifted by another, undressing another, hands, pov hands, multiple hands , etc.

Depending on how many tags you use it may start to get a slight "overfit" look so you may need to drop the lora weight under 1.0. It may not work very well with many other loras as it tends to more quickly look overfit. In that case you may need to decrease the lora weight and add more tags and increase their weight. And always use hires fix!
