Let me collapse and me on the floor.

As my body goes limp, you hold me up enough to keep your dick from falling out of my butt as you let me collapse onto the floor. As you lay me face-down on the floor, you grab my hips and pull me into more of a "face-down bottoms-up" position. This repositioning of my butt makes humping it easier, and spreads my cheeks apart, giving you a magnificent view of my hole wrapped around your dick.
