Well girl, it does not look like you will be getting your pussy stretched or well filled by some complete stranger,pity, you are missing a lot of randy fun and pleasure.
All you can do is carry on looking at the video's and playing with your dildoes, remember how it used to be in the distance past.
Your snag is that you have traded Love for Lust, excitement for security. Sure you love your husband and you will not do anything that will upset him nor would cheat on him. He as provided you with love, tenderness and safety for all these years.Join this with the fact that you never go anywhere without him means that you never get the chance to be out on your own to spread your thighs for anyone else. Somehow I don't think that he would like to see you with someones elses sperm running down your legs and well chewed nipples.
One question.... if you got the chance to have fun and get hard fucked without your husband knowing would you take it, would you risk it? Would you open wide and enjoy?
