The fucking loyalty test

My best girlfriend is now with a mate of ours...but she's not at all sure about his fidelity and therefore asks me to test him out. I invite him round to my place for a cup of tea in a sexy outfit of jeans and a white crop top that shows a lot of cleavage. At first we have a harmless chat, but when I chat him up, he quickly says yes! What a pig! Well, now I can take advantage of that and get fucked, can't I? ;) I blowjob his cock while kneeling in front of him, then I ride him. It feels totally awesome! I want more! I then ride him forwards (POV) and myself on his cock to orgasm. Finally, I wank and blow the thick cock until it squirts in my mouth, I play around with it and swallow the cum. What do YOU think? Should I tell my girlfriend about his and therefore also my arsehole? ;) #fremdfick #treuetest #cheating
