This Backdoor To Hollywood installment contains an original idea for an anal feature. There are twin sisters who have this empathy where they each know what the other is doing. The square sister is driven crazy by her sexual proclivities (that means, when one gets laid the other comes.) Straight Kascha has a nerdy boyfriend (Marc Wallice), so the quirky sister has a friend come on to him. To get even, the straight one (well, slightly crooked) sends the quirk on a wild goose chase, and seduced her boyfriend, including the obvious from the title rump-ram, leaving the cuckolded sister to moan and cry, "you bitch."
While the entire cast scores great marks for athletic performances in and around the bed, the only flaw is that Champagne looks and acts like a blonde "Barbie" on tit-steroids. Teach her to act, and this is a AAA ½ feature, which should be watched with the air-conditioner on high. Nice box cover.
