Lumina, a brown-skinned black gal working at an apparel store, usually enjoys a fulfilling love life with her similarly black gal boyfriend. However, this boyfriend is a troublemaker and a sadistic pervert who enjoys taking Lumina to happenstance bars and having her raped by creepy men that wouldn't be possible under normal circumstances. After finally parting ways with him, it's difficult for Lumina, who has been deeply immersed in perverted acts, to break free from their addictive nature. The former boyfriend was a fan of the 'Gangbang Circle,' a gathering of perverts into everything from gangbangs to public exposure and internal ejaculation. Lumina applied on her own as a lone male dog. For this masochistic beast woman who has no interest in 1v1 sex, multiple well-endowed male dogs are gathered, and when led to an erotic sweat-drenched gangbang party, her form of accepting pleasure with her whole body and soul against a live meat rod makes the ex-boyfriend want to say, 'A slut like this, there was no choice but to gangbang. I understand your feelings all too well.'
