So many lovely people here, in many sizes and shapes. I think your shape and size is lovely, xvaleriax! I am naturally medium petite, so I have known the desire to gain weight. It actually took me years to get to my current weight! But maybe, hehehe, I gained some of it in unhealthy ways with junk food and sitting on my duff a bit too much. Now, I am glad to pay more attention to being healthy and growing bigger boobies.
Since I see that you are massaging, I would like to recommend that you consider sweetyalissa's massage advice. Here is the thread:

I am mentioning it because I have tried many different massages. I noticed that many things work for different people. I find this massage a nice change after some of the other ones I have tried. As far as doing anything to increase breast size, I know most of us are here to increase size and improve our feelings toward our body, too. So, a healthy perspective is a big key in NBE success. I have definitely tried some things that turned out not to be the most healthy fit for me. As good health has always been important to me, I am glad my body has clued me in to changing my approach at times.
Good luck, good health, and good feelings to y'all, my dears.
