Looking for Satisfaction

We;ve been married many years but not the first for either of us.
My wife is very small, including her mouth and tongue. Even though I'm on the lower end of average, this makes it difficult and painful for her to engage in oral play with my member. Having my dick sucked and ramming it in to the hilt is something that really gets me off and really miss.
I'm looking for suggestions as to how to satisfy this overwhelming desire to explode deep in a woman's throat. I am 100% straight, so don't even go there. TIA!
