President John F. Kenney had been dead three years when Star Trek first went on the air—but that doesn't stop this second parody of the world-famous TV show from featuring a sex scene between JFK (Johnny Castle) and one of his paramours, Marilyn Monroe (Alexis Texas).

Seems Sulu (Keni Styles) and Chekov (Joey Brass) have been accidentally beamed to Nov. 21, 1963 and get to peep Alexis and Johnny getting it on in the Oval Office, with Johnny plunging Alexis doggie-style over the Oval Office desk, then Alexis riding Johnny's cock in both directions in the office chair, and finally Johnny taking her side-saddle on the desk—but the fact that Joey then warns Johnny not to go to Dallas the next day, thereby changing history and implicating this movie's subtitle, "The Butterfly Effect," seems to have no effect at all, and the "plot" continues as if nothing special had happened.

Three of the other four sex scenes involve crew members getting it on with the butterfly-winged babes of a mining planet. First, Kagney Linn Karter and Madison Scott double-team Spock (Tony DeSergio) by riding his cock in both directions, then spreading for doggie and spoon before the facials. Keni and Joey get seduced by Jennifer Dark, with Keni getting much more action than Joey, who too often seems desperate for Jennifer to do something, anything with his cock. Finally, Kirk (Evan Stone) seduces the aliens' queen, Kimberly Kane, with 69, reverse cowgirl, and some hot mish action that has Kimberly rubbing her clit furiously. All in all, it's a decent romp, but as a parody, it mostly falls short.
