Although I do not consider myself a cuck and I lean towards a Stag role I have found some positions make me feel differently in a MFM scenario. One that I have mentioned in other threads before was the wife and her lover passionately making out. I mean the deep tongue kissing, theme rubbing their hand all over each other including him fingering her pussy, and meanwhile I am going down on his cock getting him hard for her. There are others but for me this has made me feel more of cuck or subservient role the most.
