Mahoui Rex no Hentai Karute

After the defeat of the Demon King, a physician named Rex operates a modest medical practice. Despite the absence of war, his workload remains steady, as his clientele consists of individuals with extreme and inappropriate tendencies. These patients engage in bizarre and morally questionable behaviors, such as using slimes for illicit purposes or inserting objects into dangerous creatures. Rex regularly treats those involved in outrageous and perverse acts.
