Well, it seems you do have an interest in being cucked by her. I get the excitement of having a girl swallow your cum. On some level, it indicates her acceptance of you and her eagerness to please. In a married relationship, I feel it is a must that my wife swallows my cum. To be honest I don't believe I would have married her if she didn't. If she was willing to accept another man's cum in her mouth and felt he would enjoy her swallowing his cum and not do the same for me I would question her loyalty and devotion to me. I might feel that in some ways I repulse her or she is unattracted to me. I might also feel she is using me for different reasons other than her wanting to just be with me. For a married relationship to survive the cuckolding experience there has to be communication, respect, and devotion of both the husband and wife. If a wife does things with a lover and not her husband then the whole thing will crash and burn. If your girl is ...... to swallow your cum you might want to question her motives for being with you.
