That's kind of the part I like, I guess. That twinge in my chest when she kisses him in a way she never does with me or things like that. That kind of being left out thing gets me going like nothing else. Incest NTR is great too for it. Mom/son or brother/sister, starting off secretly just having sex but gradually hiding it less and less while they develop romantic feelings for each other, until I just get used to my big sis walking out of our brother's room in nothing but one of his oversized shirts every morning, all sweaty and with her hair messed up and something running down her inner thigh
