Does she know you enjoy it or does she think it's just to satisfy her request?My wife has told me that me being bi has a lot to do with our success in this lifestyle. It's not that she gets into guy-on-guy action, but she really likes it when I suck her bf's dick. She says it's the ultimate way for me to show my acceptance of him, as her lover.
For me, I have just enjoyed sucking cock since I was very young. I feel very fortunate that I have a wife, that not only accepts that, but encourages me.
