A grin that drips lubricity, eyes as direct and demanding as a nymphomaniac who has just flushed her medication down the toilet, big boobs engineered for maximum erotic impact, a pair of butt cushions that open up in welcome like the swinging doors of an Old West cathouse: Is there any question what brunette uber-strumpet Summer Cummings does for a living? The lady ain’t no tramp--she’s a porn star, dammit! Summer was plucked from the top of the XXX fox pile to lend realism and credibility to Boogie Nights (1997), the mainstream exploration of the blue-screen universe. Credibility and realism came in the form of Summer topless in a hot tub making out with blonde smut colleague Skye Blue. Red hot.
