Dirty Love (1988)
Big-titted blonde with long hair dominates the scene, riding her guy with her hands on her hips and breasts jiggling the whole time. The camera stays tight on her chest and the angle of her riding — you see every bounce. Later, she flips to doggy, ass up, back arched, and he pounds her deep while pulling her hair. The lighting is dim but the focus stays on her body, especially during the creampie finish. No nonsense, just solid fucking with attention on her curves.
