Threesome With My Husbands Friend

Where to start is difficult but we had never discussed a threesome, I must admit I have fantasized about having sex with Steve. But not a in a threesome with my husband. I can blame pharma but it just loosened me up.
Long story short Steve has a large penis, I had heard this but never from my husband. It was noticeable larger and it was my first one anywhere near that big, I had several longer than my husband but not like this, almost out of the gate I orgasm on him and I know this is different, he just feels incredible inside me. At first when I came I looked at my husband and it was very erotic or taboo, he seemed to be enjoying it. A few minutes later and Steve is all the way in me now and I can’t control my reactions anymore, I’m having a sort of continuous orgasm, I would have 3 or 4 climaxes and then it would just start building again. Just before Steve starts to cum I’m looking at my husband and his expression is very different now.
Be very careful before doing
