[kaiga] Chubby Succubus and Extra-Large Meaty Sex

A horned succubus confronts a sudden, extreme body change as a customer marvels at her enormous breasts, vast belly, thick thighs, and cascading folds. Her alarm gives way to boastful curiosity when she notices how quickly he becomes aroused and invites him to use her navel, turning the new proportions into the encounter’s teasing centerpiece. The promise that she will remain in this form for a whole month gives kaiga’s weight-gain premise its momentum, with the rough translation heightening the deliberately crude, playful tone.
