My wife much prefers fucking so we may start in a mutual masturbation position but not complete that way.
For example, sometimes when Bunnie is tired she will lie on her side and I will kneel behind her ass, put my cock between her ass cheeks and masturbate. Meanwhile she'll be rubbing her clit. When I cum I aim so that it runs into her pussy and she'll get it on her fingers and rub it onto her clit as she cums. Most of the time we do not that far as, as the actions can raise her energy level and she will want to change to fucking position.
Another position Bunnie likes is to rub and finger her pussy, while I fondle her tits and and stroke my cock over her face so she can lick it. But again most of the time we change to another position before either of us cums, or she will cum and then want to fuck so that I can cum.
No matter what happens, it is all fun.
