It's summer vacation, and Kou is back in the peaceful countryside after more than a year away in the city. His cute little cousin Anna, who calls him "Kou-chan," greets him warmly. She has grown taller, learned new things, and most importantly, her feelings of "like" for her older cousin have grown much stronger—almost overwhelmingly so.

The two quickly fall back into their old routine, reminiscing about their childhood. They revisit the inconspicuous hut where Kou once tried to seduce Anna during his previous visit. Now older and more confident, Anna is determined to show Kou just how much she has "learned" and how ready she is for a deeper connection. What begins as nostalgic teasing quickly escalates into passionate, loving sex filled with blowjobs, creampies, and raw emotional intimacy.

This vanilla hentai OVA, based on Shouji Ayumu's beloved manga, captures the sweet yet erotic tension of forbidden cousin love. It's a heartwarming and highly arousing story about growing up, unspoken feelings finally being noticed, and indulging in "various things" together during a long-awaited reunion. Perfect for fans of pure romance mixed with explicit, tender hentai action.

Based on the adult manga by Shouji Ayumu
