A dedicated scientist, Laura Manning has an I.Q. that's off the charts. But beneath her pristine white lab coat is a curvaceous body that craves satisfaction. She finds it hard keeping her mind on the experiment and off what's under the lab coat of her bad boy research partner, Jay Cutler, whom she's working with to develop a libido suppressant, an ""antidote"" for a society gone sex-mad, pumped up and over-stimulated by the miracle of Viagra.

With time running out, Jay offers to act as a human guinea pig, injecting himself with the libido suppressant. Laura's role requires lingerie, soft music and candlelight. Her job is to entice him, to determine if the suppressant tamps down his desires. Rather than cooling the flames of lust engulfing them, their ""antidote"" only heats them up . . . and there's only one scandalous way to deal with it!

Suddenly long days of laboratory work are giving way to sizzling nights of sensual experimentation—and a different kind of ""chemistry"" that leaves Jay and Laura breathless and gasping for more! Their professional careers may depend upon a successful climax—and there are dangerous competitors determined to steal their research. And maybe their pleasure games have gotten a bit out of control.

But who in her right mind would want to pull the plug on her man's libido when the loving is this deliciously hot?

Who better than Sam York—a super-brain blessed with the body of an Adonis—to head up the research team entrusted with developing the greatest scientific breakthrough since Viagra? His experiments with female libido enhancers need one more crucial test: on a willing human subject. And when ace reporter Cathleen Nichols, the sexy, nosy neighbor Sam's been lusting for, exposes the lab's provocative work in a revealing article, the genius stud knows he's found the perfect participant.

Though Cat has kept her feelings hidden, Sam has been secretly stoking her inner fires for months. Now, with Sam's "wonder formula" tossed into the mix, their unleashed passion is off the charts, rocketing them together into the stratosphere of erotic ecstasy, no emotional strings attached.

In the name of science and journalistic investigation, suddenly nothing is taboo. But what happens when Sam and Cat's sizzling, sensual pleasure game starts to turn into the real thing?

Once a mere lab assistant, Erin Shay is thrilled over her new promotion. The curvaceous, brainy, somewhat straightlaced lady has been placed in charge of an important new research project: testing a serum specially designed to substantially prolong a couple's lovemaking. With scientists Jay and Laura off on their honeymoon, Erin's been left alone in the lab . . . with her hard-bodied new assistant, Kale Alexander, a sexy stud who has ""playboy"" written all over him.

Erin's never even had a one-night stand—but the project's success depends upon her playing the wild, wanton bad-girl to red-hot Casanova Kale. Since she's already learned the perils of leaving her heart too open to heartbreak, this time she'll be the one calling the shots. Her bad-boy partner is going to know from the git-go that this will be a brief sex-only affair—hot, torrid, steamy love in the interests of science . . . with absolutely no strings attached. But when the loving is this deliciously hot, who in her right mind wouldn't want to prolong it?
