Yuri and Yu are demonstrating the newest sex invention in a Japanese infomercial. The girls apply a special lip stick, which enhances their desire to suck two volunteer's cocks. The guys eat special chocolates, which makes their cum taste sweet, and the girls hornier. Swallowing every drop of jisms, the girls prove it works. But, they are hornier than ever. So, two more studs use vibrators, before fucking them intensely.
