Quote: Stimulating her during IC is another thing I would like to do but don’t know how. With the aforementioned weight problem, I just don’t see how it’s physically possible in the positions that are “allowed”.
How about the starfish? Her on her back. You on your side approaching under her legs. Together you form an "x" touching at the squeezy bits. The weight issue probably makes her not want the woman on top position because she feels too exposed. The starfish does not cause such exposure, can even be done under the covers.
