La orgía de los muertos (1973)

Starts with this hot blonde MILF in a dark dress pressing up against some dude in the woods. She’s got that shoulder-length wavy hair and a body that’s all tits and ass, not skinny but not overweight — just thick in the right places. They’re making out hard, his hands all over her, and the camera’s low so you see her cleavage jiggle when he grabs her. Then it cuts to this other scene where some guy’s holding a knife like he’s about to stab someone, which is weird but kinda hot in a dark way. Later, she’s back in a fancy room holding a candle, looking all dramatic, but the real action is when they take it outside — doggy style on the grass, her ass bouncing while he pounds her from behind. The lighting’s dim but you still see everything, and the close-ups on her face when she’s getting fucked are solid.
