Not all that surprising. Most of the women I have fucked over the years would do things with me they would not do with their husbands. They were afraid that if they really turned loose that their husbands might not see them as the prim and proper soccer moms that they are.
Bondage can add to the experience, personally I find it fun to tie a woman up so she is spread open for easy entry. Then spend some time lightly caressing her while telling her what I am going to do to her. Most of the women I have done bondage with won't/don't do it with their husbands.
The relationship with me is much simpler than with their husband. They meet me for pleasure so things in that area are much less restrictive than at home.
