Superfuckers 15 (1970)

Whores come a dime a dozen. Superfuckers are one in a million. These exquisite sluts are genetic miracles, their perfect bodies imbued with an astounding hunger for prick. Professor Flynt's school for exceptional cock-sockets hones these whores into perfect sex machines. The anal room, our high-tech, hard-core training grounds buried miles beneath the Flynt Mansion, is where all the action happens. A flawless body is stripped and spread. Cocks attack from every angle, penetrating and stretching ass flesh to its limits. Breasts are manhandled as dual joints piston a ravaged crack. Intense bursts of splooge blind the babe, befouling her stunning face.
