What are some of the most pleasurable positions that chubby girls can try while doing the deed?

I've only been with a few girls. Most of them were some kind of "skinny." I've started seeing a new girl, and she is chubby. There's nothing wrong with her weight, I love her, but I just want to know what kind of positions she might find pleasurable. Forget about me. It's all about her. Thank you.
