hmm... try making a cute-breed dog into a demony girl for you to bone?

I can't really suggest positions without knowing the level and type of energy you want. I mean, if you want something sweet and passionate... pressing her up against the wall as you load her up is not really the right energy. There is always good old doggy style... classic and easy to tweak for different intensities...

I am full of ideas really, but do not know what you are looking for... and today i am so tired that i would probably fail to type out my ideas clearly.

actually i got a volunteer for the bending over against a wall <.< the sketched version should probably appear later tonight <.<
