Inside Everybody (1984)

Thick black girl with short dark hair is on her knees first, sucking a white guy with a curly light brown mullet and mustache. He’s average build, looks like a regular dude — not a gym rat or porn caricature. The second girl, a slim brunette with long hair, joins in and they start double-teaming his dick, switching off, slurping and spitting on it. Camera stays close, lots of faces in frame, you see every wet pull-back and lip stretch. Candles in the background keep the room dim but lit enough to catch all the spit trails and facial expressions. Guy lasts a while, but they eventually get him to blow — messy finish on the second girl’s face.
