I think it's especially hot that you are orgasming so regularly with your new lover, and the focus in general seems to be on YOUR orgasms when you are with him. Have you always cum so regularly during sex, or are you getting off more often (or more intensely?) as a hotwife?
Anyway, congrats on your success! As an aside, please remember how special your husband is for letting you experience these amazing pleasures in the safe context of your marriage. It's really important to make sure he always knows how much you love him, and that you always put him first, no matter how often or how hard you cum with your lover. I really can't emphasize this enough. Make it a habit to always show him how grateful you are!
