Imouto to Sono Yuujin ga Ero Sugite Ore no Kokan ga Yabai – Episode 2 (RAW)

When Miu’s grades force her brother Kanata into the role of tutor, the little sister only agrees to the lessons if her best friend can join. Riko shows up with light-brown twin tails, an outgoing personality, and a very different body type from the flat-chested Miu. The cheerful girl takes an immediate liking to the skilled older brother and uses every study session to stay pressed against him, flashing playful, almost devilish smiles. Miu watches with growing irritation, but this episode belongs to Riko. The focus shifts to the sister’s friend as her lighthearted teasing turns into sustained erotic attention. Scenes emphasize Riko’s energetic affection, her bouncing figure, and the contrast between her open interest and Miu’s tsundere reluctance. Released in late 2016 by Collaboration Works as the second half of the OVA pair based on the Pachipachi Soft visual novel, the Riko edition delivers a concentrated look at the cute, busty friend route. For viewers who prefer the lively, well-endowed girl over the prickly little sister, this chapter gives her the full spotlight and the intimate payoff that comes with it.
