Double Duty Nurses

A physician named Ryouko Makimura has developed experimental libido-enhancing pills — one formula for men, one for women — and she needs test subjects. Her solution: herself and four nurses from her ward. What follows is a 2-episode OVA from Studio Eromatick that leans hard into the 'what if a medical professional made some very questionable professional decisions' premise, complete with unexpected physiological side effects that the characters definitely did not plan for going in. The setup is straightforward but the execution keeps things moving, with each nurse reacting differently to the treatments, which gives the short runtime some actual variety rather than just repeating the same scenario twice. It's adapted from a visual novel, so there's more narrative framing here than you might expect — the drug trial structure gives the story a loose through-line that holds the two episodes together. If you've watched Yakin Byoutou and wanted something with a more clinical, experimental angle, this scratches a similar itch. Fans of Sakusei Byoutou's hospital setting will also find familiar territory here. It's a niche release, but if medical-themed hentai with a sci-fi tinge is your thing, this 2007 OVA delivers exactly what it promises without overstaying its welcome.
