Tsun Tsun Maid wa Ero Ero desu

Lazy, perverted, and apparently incapable of managing his own life, teenage disaster Eishun Makio is exactly the kind of kid who needs someone to keep him in line. His mom's solution is to send in Kiriha Hariyama, his childhood friend, to keep him in line. She shows up in a maid uniform and immediately starts confiscating his adult magazines, which only makes things worse, because now he's fixated on her instead. Kiriha is the textbook tsundere, sharp-tongued, strict, and clearly hiding something beneath all that bossiness. The push-pull between these two is really what carries the whole thing. She acts annoyed, he acts shameless, and the tension between them builds naturally from there without feeling forced. This 2-episode OVA from Studio 1st is adapted from a light novel and leans into both the comedy and the erotic elements without abandoning either. The maid-and-childhood-friend setup is a familiar one in this genre, but the tsundere dynamic gives it a bit more personality than you'd expect. If you've watched something like Aneki no Kounai Kaikinbi or Resort Boin and wanted something with a slightly more comedic edge to the character writing, this scratches that itch. It's a short watch, nothing that overstays its welcome, and the animation holds up well enough to make the two episodes feel worthwhile.
