Ecchi na Oneechan ni Shiboraretai

After being away for a while, a guy returns home to find his two older sisters very happy to see him — maybe a little too happy. Megumi is the outgoing, assertive one who makes her feelings known pretty quickly. Ayami is softer, sweeter, gentler about it. Both of them want their brother's attention, and the whole two-episode OVA is basically about navigating that situation inside the family home. It's cozy, familiar in setting, and the dynamic between all three characters is what carries it. The tone stays lighthearted throughout — there's no dramatic tension or heavy plotting here, just character interactions with a sensual edge. T-Rex handles the animation well, and the character designs are distinct enough that Megumi and Ayami feel like actual individuals rather than interchangeable archetypes. If you've watched something like Ane Koi: Suki Kirai Daisuki or Nee, Chanto Shiyou Yo and you appreciated that sibling-focused dynamic, this sits comfortably in the same space. Fans of Ane Yome Quartet will also recognize the general structure. At only two episodes, it doesn't overstay its welcome. It's adapted from a doujin manga by Joy Ride, so there's a source if you want more context on the characters. Worth checking out if sibling-dynamic hentai OVAs are already your thing.
