Best friends Rika and Mitsuki are drinking with director Choco when their usual party chant sends the night into full drunken chaos. They invite a rookie porn actor over, play drinking games, and quickly turn sex into the night's main entertainment. The wild gals tease, ride, suck, swallow, and keep attacking until his rock-hard cock erupts, filling their bodies with semen while they continue drinking and chasing more pleasure.
