Based on the provided image. Primary Motion: Medium-paced rhythmic pelvic thrusts. During the creampie, her body jolts and shudders from the heat of the ejaculation. Expression: Keep her eyes dreamy, half-lidded, and unfocused in pure bliss. (NO wide open eyes), (NO rolling eyes). Secondary Motion (CRITICAL): The cross-section view in the upper right corner must be fully animated. The internal phallus in the cross-section must move back and forth in perfect synchronization with the external pelvic motion. Show white cum swirling and filling the internal womb area during the climax jolt. Constraints: No body morphing, steady camera focus on her dazed face and the dual-action (external and internal).
