Buy her really good quality dildo's, make sure you warm them before using them on her, she will cum her little married pussy off like your never seen her do before if to do in right, Oh, don't go to big with the dildo to start with, 1 to 1.5 inchs longer than your dick and .5 of an inch thicker and slowly work up from there
You wont need to make her want big cock, all you need to do is to give her the confidence and permission to go out and get it, she will do the rest
I have to add, and I think I hear you saying it, there is a huge difference in the feel of the best dildo and a real cock, so if she is wanting the real thing to make it happen. for me I have no use for dildos unless I am playing with another woman or pegging a man, I want the real thing inside me. But good luck we all advance at our own pace.
Her telling you she prefers your cock inside her and not something big is just her protecting your ego, that's all
That sounds so hot, I love doing that with my husband, but I sometimes ask him to guess who I was thinking about fucking as he makes me orgasm with the dildo
