Arisa is an obedient sex slave who cannot resist the man. The man's sexual desire also targets Arisa's cute best friend Sara. He hints that he will make her his official girlfriend, and gets her to propose compensated dating, which he uses as a threat to make her submit. While the two are devastated by the sadness of being betrayed by their friend and the guilt of betraying him, the man forces them into lewd play. He unleashes his desire on the girl's vagina and ejaculates inside her without any remorse. *This work is a re-edited version of "Best Friends, or Sisters" (product number: 24bfd00004).
