That JAV

Sisters "Airi" and "Wakana", who are good friends, were troubled by the noise of an AV nerd every day. One day, after complaining directly to a man about garbage, Airi is knocked unconscious by chemicals and taken to her room. Her sister Wakana is taken in as well, and when "Airi" sees her neighbor raping her in her sleep, she tries to escape and is raped in reverse. After that, the two are kime-sexed with an aphrodisiac, and are swallowed by the pleasure of the aphrodisiac, and fight fiercely for their cocks.
