Recently, Harley Quinn found out you have a thing for fat girls. And you know Harley, she will do anything for her Puddin' Mr. J! She's been packing on the pounds herself, but it's just not fat enough for her. So she's had a special experimental potion made that is supposed to help her put on weight super fast. It's been about 30 minutes since she took it, and she's expecting it to kick in any.... oh my, Harley is feeling a bit funny. Suddenly Harley starts to expand and get fatter right before your eyes! All the fat and growing feels so good it's making her feel orgasmic. But as she continues to grow, she starts to get a little scared that her expansion won't stop and she will explode! She begs you to fuck her to stop her from bursting! Will you help her Mr. J?
