Angela, The Fireworks Woman (1975)

Angela’s on all fours in the dim light, ass in the air, getting pounded from behind while the guy cracks a whip near her back. She’s a slim brunette with a tight body, screaming in frame 5 like she can’t handle how deep he’s going. The scene cuts to her lying on her back, naked and covering her tits, looking wrecked after a brutal session. Most of the action is hard fucking — doggy style, then her riding him with that long brown hair swinging. Ends with a thick creampie shot across her face while she gags on his dick. Camera stays close during the blowjob, capturing every messy second.
