My daughter (early 20s) has had several boyfriends in the last year and told my wife recently that the guys were pretty rubbish sex wise and she really only wants and enjoys oral. My wife then revealed that penetrative sex is rare for me and I'm expected to give my wife good oral too. She didn't reveal about orgasm denial/chastity for me! I was surprised the conversation even took place and I guess it shows how the sands are shifting.
Mistress B, not so surprised about them chatting about sex, but more that my wife revealed what she did and obliquely hinted at orgasm denial and chastity as the way to go.
Nice, hopefully my Mistress raises our daughter to understand the way things work! Little one (11) has alread noticed things have changed around the house, and knows to ask "mom" for permission to do things, but comes to me when she needs laundry done, hands me her dinner dishes, etc...
