*Not a threesome - Han Su-Jin just masturbation*
Lee Han has Han Su-Jin set up a dinner with her, her husband, Lee Han, Kim Eun-ju and her husband. Lee Han asks to escort Kim Eun-ju out after dinner and her husband ignorantly happily allows it. Lee Han starts to manipulate her in the stairwell about her husband cheating and asks for one last time together. Kim Eun-ju agrees and gives him a blowjob. Chapter ends with Lee Han cumming in her mouth (Chp. 49)
Lee Han isn’t satisfied yet and starts eating Kim Eun-Ju out before fucking her in the ballet dancer position. Han Su-Jin hears a moan from the hallway and peeks through the door to see Lee Han fucking Kim Eun-Ju right after eating dinner with one another. Han Su-Jin’s pussy starts to get wet while watching them (Chp. 50)
Lee Han notices Han Su-Jin watching and starts telling Kim Eun-Ju that she’s prettier than Han Su-Jin as he fucks her in reverse cowgirl. Han Su-Jin notices that Kim Eun-Ju likes it and starts fingering herself watching them. Kim Eun-Ju fucks Lee Han in cowgirl and asks him to pull out but he can’t help himself and creampies her (Chp. 51)
Kim Eun-Ju doesn’t seem too mad and the scene ends with Lee Han imagining both Han Su-Jin and Kim Eun-Ju in the bed next to each other in lingerie (Chp.52)
