Amber Pays the Rent (1986)

Starts with a slim blonde—Amber—going down on a brunette with a navel piercing. The brunette’s got long dark hair and a tattoo on her lower back, and she’s lying back on the couch like she’s loving every second. The camera gets right in there, so you see everything. Then a guy in his 30s shows up, and things shift to a threesome. The blonde sucks his dick while the brunette fingers his ass or plays with his balls—hard to tell, but it’s hot either way. Later, the guy fucks the blonde doggy style over some gym equipment, which is a nice change of scenery. Ends with him eating out the brunette on the bed, slow and steady. Good mix of positions and angles, nothing too fancy but it works.
