1- Tight-legged
Getting into the typical doggie stance, have your girl keep her legs closed and open yours around them. As well, get her to arch her back and lean on her hands rather than lean down and rest on her elbows on the bed (or whatever surface you happen to be on). To help her maintain that stance, wrap your hand around her hair and give it an occasional tug while you`re having sex.

In addition to hair-pulling, you can rub her spine lightly and even hug her waist while you penetrate her.

2- Upright torsos
Get into your regular doggie stance, but lift your torso along with your girl`s so that you`re upright while you penetrate. Doing this in a location where she`s facing the wall or, say, the bedpost, will allow her to place her hands there to maintain balance while you`re going in and out.

Use your free hands to caress her breasts and butt, rub her shoulders and get a better grip for penetration. This position also allow you room to easily kiss her mouth and neck.

3- Stand down, boy
While she bends over on the edge of the bed, her feet and shins hanging off it, you stand against it and make your way in. Of course, if the bed is too high or you have a significant height difference, you will have to make some adjustments.
She can raise or lower her body to accommodate you, and you can stand straight or bend your knees.

4- Stand down, girl
If she`s much shorter than you, you may not want to attempt this position. Otherwise, have her face the other way and bend down so that her butt is sticking out toward you. Her torso should be parallel to the ground.
While you kneel on the edge of the bed, hold on to her hips and make your way in. Make sure to go slowly, as she needs to maintain her balance. Better yet, let her control the tempo.

5- Climb to the top
While she`s in position, stand up and place your body right above her butt. Then, bend down so that you can place your P inside her.

Ensure that you`re balanced otherwise you may end up falling on top of her. Place your hands on her back without pressing down, or use the help of a wall or bedpost to maintain balance.
Be careful not to thrust too quickly initially ensure that she enjoys the sensation first.
