Photographing larger models can be extra challenging, partly because the subject might be more tense, and partially because certain poses might be better than others. All you can do with the first problem is to be reassuring to the model. You can do that by suggesting good poses for any particular body shape.
Some things to consider are:
1. Use poses where there is space showing between the arms and the body. That avoids the width of the arms adding to the apparent bulk of the torso.
2. Hide sensitive parts of the body with strategically placed things. For example:
* wrap a towel around a stomach
* use a garment such as an open shirt to distract the eye
* obscure the torso with lace lingerie or a mesh garment, some straps and fetish gear. Even a simple black belt can work
* ask the model to lie on her back and draw one leg up and over her stomach
3. Use classic poses such as:
* model lying on her back, looking up with her hair arranged round her head, and well lit
* model lying on her front, raised on her elbows with boobs showing
4. Avoid side shots; angle the body at 45 degrees to the camera to reduce perceived body bulk
5. If the model is big, strong, and with good posture, consider "going for it" and using forward leaning "aggressive" poses.
