Tsugou no Yoi Sexfriend 3

Arahama Yuu’s carefree arrangement with five sex-friends spirals into chaos when Shimizu Misako, his co-worker and lover expecting marriage, confronts him. Enraged, she gathers the others—café owner Yanagi Ryouko, schoolgirl Hoshino Kotori, executive Endou Makiko, and online date Kamishima Aina—demanding he commit. In the heat of passion, Arahama impulsively proposes to all five, igniting fiery encounters filled with desire and confusion. Later, he desperately attempts to retract his reckless vows, visiting each woman to mend their tangled hearts while wrestling with the lingering flames of intimacy.
