Completed manga about two men and a woman. One man loses part of his memory (I think he's possibly married to the woman, or he's dating her?) They have a 3some, and the guy who lost his memory remembers the "rhythm" of the other man's thrusting. Pretty sure in the end the two men kill the woman, and the memory loss guy remembers that they had planned it...?
