You come

Screw Michael. Or rather, don't screw him. He can deal with his cock himself. You surrender to the warm feeling building inside you, and in no time at all, you have the best orgasm you've had in days. Your best vibrator is no match for Christina's expert ministrations, and not for the first time you wonder why the two of you don't do this when you're all alone.

As you lie there in Christina's arms, recovering and relaxing, you hear a grunt as Michael gets his own release, followed by a, "Shit," probably because he's gotten cum on something important. It takes Michael several minutes to clean himself up, and then he walks over to the two of you. Looking down at your nude bodies is enough to get him hard, apparently, as the outline of his dick bulges against his trousers. You give a coy smile and stand up, making sure to brush your hand against his package as you do.

"So, was that worth your while?" you ask, your tits nearly touching his chest, your breath hot against his face.

"I'd say so," Michael says. Then, unexpectedly, he grabs you by your waist and turns you around. He gives you a firm slap on your ass. "Get dressed--at least as much as you can--and I'll show you around."

Once your bikinis and sarongs are once more secured, he leads you to a door in the wall opposite to the one with the main entrance. He keys in a code--5213--and opens it, revealing a nondescript hallway of grey doors. "Now, I can't show you everything. If I even get caught in here with you two, it means my job--if I'm lucky. But if I show you the super-classified projects, we'll be lucky if we make it off this island." When he sees you stifling a giggle, he redoubles his effort to look and sound serious. "It's not funny, Ally. Your father might be a bigshot in the corporation, but that doesn't mean he can protect his daughter if she's brought up on company charges of espionage."

You push past him to enter the corridor, turning on one heel to look back. "Chill out. Are you coming?"

Michael retakes the lead, and the two of you follow him down a twisted, complicated route of endless, same corridors. Frankly, you're lost after the first or second turn and won't be able to find your way back without him. Spaced somewhat evenly along the corridors are plain doors with only alphanumerical codes to indicate what might lie beyond them.

Eventually Michael stops outside one door. "Ah. I suppose I can show you this, seeing as how neither of you are likely to be hiding sampling equipment in your wardrobe...." He keys in the same code, 5213, and the door clicks open.
