Yes, but it will take more time.

"Now I can think," she tells you as she pulls out and puts it away and gets her clothes in order. She pulls up your panties and puts your skirt back down. She pats you on the butt. "I think this is going to have to get bigger. I know it already sticks out like a couple of feet, but it won't stick out more than three feet when I finish. I'm going to make it wider, mostly. You still have skinny hips, I'm going to make those twice as wide. And your thighs will be made to fit with your new curves so you don't look fat. Then, you should be able to walk around easily. Of course, if you cause me to cum the special sauce on your tits again, this load will probably end up making you, like, a twenty or something. Then you really will need to have a big ass, probably stick out 6 feet or so and be so wide I could grind my whole body against it...mmm yummy." She smiles. "But we can stick to the plan." She runs off.
