Cowgirl, Hotseat and Other Good Rides
No matter what some of the "jokes" in bad movies may say, a larger receiving partner can be on top without hurting the person underneath them. You'd be surprised how much pressure and weight the hips were really designed to hold! The partner on top may want to come down onto their knees instead of squatting for an easier time moving. A position aid here can make things a bit more comfortable too.

Stand and Deliver
You might have to hunt around your home for a bit, but if you can find a surface for the receptive partner to lie on that's as tall as hip-height for the penetrative partner, you'll find that it might work particularly well. For some people, the bed may work fine. For others, it might be the kitchen counter. Whatever it is, make sure it was designed to hold body weight. With the receptive partner lying down at hip level, the penetrative partner can stand (or kneel, as shown below) during intercourse.

No matter what position you choose, the most important aspect to remember is that you both may need to modify the position to meet your individual needs. Your body is your body and their body is their body. You both should try and be comfortable with rearranging your bodies (and any particular weight) as needed. Sometimes moving areas out of the way will allow for deeper penetration and enjoyment. Sometimes you may not have the upper body strength, flexibility, or stamina to hold a certain position for a long time. Being comfortable with your bodies, and how they fit together, will help you both establish the comfort that you need to explore how to make these sex positions perfect for both of you. (When it comes to, well, coming, being comfortable is key. Read Why 'Comfort Sex' Rocks - and How to Have Some.)
