Playing Dumb

I've been married to my husband for 12 years. We have no kids and probably won't. He's too busy and honestly I an scared to go through it all and ruin my body. Selfish, I know. But I'm just being honest.

Anyhow, this is my confession.

My husband is an identical twin. I have been with him since college. He has never admitted this to me but he's let his brother fuck me many times before and since we've been married. I knew who it was every time. It would always be him waking me up with oral while I was asleep. It's not that my husband doesn't do this. I told him when we first started having sex that that was my favorite way to wake up.

They are both so arrogant to think I wouldn't know the difference. They are almost exactly the same physically. But his brother eats pussy so much better. It's as if he's devouring it while my husband is just doing what he thinks gets me off. The brother likes to fuck slower but more forcefully and he cums quite a bit more. Their dicks are as close to identical as can be. I'm sure side by side there would be some differences but I really can't tell.

I have known all along but after the one time I asked and he laughed and said no f-ing way, I've never brought it up again. I enjoy having two lovers. I prefer his brother fucking me and look forward to each time.

I wonder if I should say something to the brother like he can have me whenever he wants and doesn't have to pretend he's my husband.
