I don't know about you but watching my wife passionately kiss her bull and have her breasts and pussy felt up before the action starts is harder to take than when he fucks her. Call me strange I guess.
The last time my wife and Axel had sex, during missionary position, they kissed each other a lot. He just stopped the kisses some seconds due my wife asked him to suck her nipples. Axel is shorter than my wife, so he's able to reach her tits easily. Once he stimulated her nipples, with his mouth, according my wife wishes, he searched for her lips again and they kissed until my wife finally cummed.
