I would have slipped out a few times leaving wifey very frustrated. At least she can ride his cock and focus on her pleasure instead of a shorter dick always slipping out everytime she wanted a longer, deeper thrust. Hubby has no choice but to be happy for her.
Those big beautiful hips and ass are made to take large cocks, no matter the race. No need to unlock hubby. If he can't bring you pleasure then why should he get pleasure?
Isn't it awesome to be able to enjoy bbc as much as your sissy husband. My wife is no sexual. But I enjoy bbc as a sissy crossdresser and it's the best sex I've ever had. Of course I am in chastity. And it's all about his pleasure. Such a wonderful feeling and wonderful life. I'm happy for you both. Enjoy that BBC and keep it cumming!
