WANZ-373 - Hey Brother, Be My Condom Practice Dummy - Yu Asakura

It's been a while since I watched an Asakura Yu film, and it has that reliable quality. She plays the 'sexy older sister' role well, too. However, the situation in the title—practicing putting a condom on her younger brother—was incredibly erotic, but that only happens at the very beginning and then it just disappears... They end up having unprotected sex, which makes the whole premise feel pointless. That was a shame.
