I invited a friend over to the apartment where I live with my girlfriend for a relaxed night of drinking. The atmosphere was great, conversation flowed easily, and eventually we started talking about the NTR porn I'd been watching lately. My easygoing friend grew curious, gradually getting into the idea. Though a bit hesitant at first, my girlfriend—crazy about me and sex—agreed to go along with it. Finally living out my fantasy, I experienced an incredibly intense session, but then... isn't she getting too into it? Does she actually like this guy's cock? Did she just cum again? Watching right before my eyes as my horny girl sinks deeper and deeper into depravity, I feel a tinge of sadness, yet somehow understand—this is what NTR is all about.
