Sexual act of penetrating an obese woman:

Doggy style, placing the penis into the ass crack, then generously smacking the right and left butt cheeks simultaneously which generates a fatty suction wave, pulling the penis into a mystery hole, either the vajayjay or pooper.

Note: Requires minimal effort for penetration.
