The Wayward Mistress (1973)

This one’s all about a slim brunette in her 20s getting fucked doggy style on a bed. She’s petite, white, with long wavy hair and a tight body. The guy’s older, muscular, short brown hair, and clearly into her. They start with her sucking him off, then he eats her out before bending her over for doggy. The lighting’s soft with warm tones, making her skin look smooth and glowy. There’s a mirror scene too, where they pose a bit, showing off her ass and his build. The close-ups are solid, especially during the oral parts. No crazy acrobatics, just straightforward fucking with good angles.
