True Sister

Surprised by her friend’s black boyfriend’s stuff, what’s her choice? Let’s swap partners! A young couple’s conflicting desires!

While Seon-hee is on her way to her friend Mi-soo’s house, she’s surprised to see a black man chasing her. It turns out that the black man is her friend’s boyfriend, Andy. While having a chat with the couple, Seon-hee is surprised by Andy’s big stuff sticking out of his pants. Mi-sook gets excited about her friend’s situation in the living room, so she goes into the room with her boyfriend to have sex. After hearing her friend’s moans, Seon-hee calls her boyfriend, Joo-ho, to have sex with him on the pretext of inviting him over to have dinner together. Meanwhile, Mi-sook is dissatisfied with her black boyfriend since she does not understand him well, even though she likes having sex with him, so she consults with Seon-hee, who is interested in Andy, and suggests that they switch partners. Joon-ho, who is interested in Mi-sook, consents to having sex with her, pretending not to win over her. Mi-sook then proposes to her free-loving boyfriend to have sex with her friend, and Andy, who is interested in Seon-hee, also consents to do the swapping.
