Are you looking for maximum penetration. Sure you can do the cowgirl or reverse cowgirl, but what about getting him on top? There are so many ways you can play with your legs in the air and take it from someone who has been basically all sizes anyone can do it. 

There is always your basic legs up position. He kneels on the bed, you put your legs directly on his shoulders, you bend your knees a little. You place your hands on the back of your thighs either right above the knee or towards your ass. He pushes his palms or fists on the bed right outside of your legs. Then he thrusts it in you. He can lean in as much as he can, (sometimes he can even go low enough to kiss you). You can put your arms around his neck. It feels amazing if he starts out slow, almost completely pulling out and pushing it all the way in so you can feel every inch of him then surprise you by pounding it in you hard. Trust me that will make you moan. If you want to get a little sexier you can grab your tits and try to push them to your lips and suck on them or bite them a little. It will drive him wild! If you want to get really creative cross your legs and put each leg on the opposite shoulder. The pressure between your legs will make it feel tighter for him and for you, in the best way possible.

 If your legs can’t go all the way to his shoulders (or even if they can) have him put his hands between your legs with palms up against the bed or on the back of your thighs right above your knee. Place your legs over his biceps and your hands either right on top of his or under his. 

As he pushes in and out of you make sure you match his rhythm. The more you move along with him the better it will feel for both of you. Try sitting up a little, kinda like you are doing a crunch and feel that deep penetration. Look into each other eyes as you both move slowly, the passion will be more intense. Then quicken the pace, have him shove it inside of you as deep as possible then quickly out again, if you get into a perfect rhythm you can almost hear a suction between your bodies or at least a smacking sound. 

You can also try this with your ass to the edge of the bed/couch/ table/ etc. Havr him stand with his knees slightly bent to meet up to your wet pussy. To shake it up a bit and give you an incredibly deep penetration he can put his hands on your ankles and lift your legs up and down while grinding up against you. 

Maybe try spread eagle with your hands as close to your ankles as possible and his hands on your ankles. Try pressing your knees up against his chest with his hands on your ass shoving his cock inside of you. Try wrapping your hands around your calves, reaching around your leg from the inside out so that your finger tips are placed on the outside of your calves. Another thing you can do is put your legs up and wrap your arms around his forearm as his hands are pressed up against the bed. Put one leg up and the other leg down. Put your hands against the wall or backboard, hold your tits, have him pin your arms to the bed by your forearm or wrap your arms around his inner arm with finger tips out. 

There are so many things that you can do with your legs and even more that you can do with your hands, but no matter how you have your hands or legs, you will definitely feel that deep penetration.
