San shi nian xi shuo cong tou (1982)

This one’s got a hot blonde with big natural tits getting absolutely wrecked by four dudes in a grimy industrial dungeon. Starts with her on her knees sucking one guy while another preps her ass—no warm-up, just straight to DP. The camera catches her face when the second dick slides in, and she looks like she’s loving every second. Later, it turns into a full-on orgy with all four guys taking turns, some just watching and jerking off while she gets pounded from both ends. The lighting’s dim with red bulbs, so you get that moody, underground feel. If you’re into rough group stuff with a girl who can take it, this delivers.
