He glanced at the nightstand. In the pitch dark of his room he could barely make out the glow of the alarm clock, which he’d turned away from him. Now he felt his way onto the bed and crawled over to it, turning the clock around to read the time.

Room service at two thirteen A.M.? Did this hotel even have twenty-four-hour room service? Or had Diana persuaded someone to break the rules for her? Tim had a feeling Diana had spent her entire life tempting and cajoling and getting exactly the result she desired.

A spark of irritation ignited within him. Though he felt a now-familiar stirring at the thought of her, his frustration at this long night of broken sleep trumped any lingering arousal.

From next door he heard the sound of a door closing, and he assumed the room service guy had left. But a moment later the murmur of voices began again, both hers and a man’s, and then they moved nearer and he heard the creak of weight upon the bed.

“Trust me,” he heard Diana say, “this is going to be the best tip you’ve ever gotten.”

Tim couldn’t help himself. He laughed softly, falling back onto the bed. “You’ve got to be fucking kidding me.”

But he should not have been surprised. Diana had told him that if he wouldn’t come over and have sex with her, she would call room service. He supposed things like this must happen fairly often in the real world, but to him it seemed like something out of the Penthouse letters page or some porn film.

Already the noises had begun. How fast had she stripped the guy? Tim lay there staring at the ceiling in the dark and listened to the grunts and moans quickening. Diana urged the room service delivery guy in words almost identical to those she had used with her lover of the previous night. Tim began to get an erection, and he felt a ripple of anger at himself. Tired and frayed and amused, he should not find any of this arousing, but he could not help himself. Men were pitifully predictable creatures.

Not so predictable, he thought. You didn’t go over there.

But he knew that meant little. Under other circumstances, he would have jumped at the chance to be with a woman like Diana and been just as grateful as, no doubt, the room service guy felt at that very moment.

The noises in the next room reached an initial crescendo, with Diana crying out in a throaty, shuddery orgasm followed almost immediately by the groan of a man stunned by his own good fortune. If last night was any indication, though, Diana would not let it go at that. As soon as the guy had a few minutes’ rest . . .

The groan had not stopped. The man’s voice began to rise and fall, perhaps with each spasm of his own orgasm. It sounded like he was still coming, like she had brought him to the height of ecstasy and somehow managed to keep him there. The guy cried out to God, but even those words were barely more than grunts.

The headboard slammed the wall in quick rhythm, punctuating each spasm. Diana talked to him, urged him on, and Tim wondered what kind of woman this was, what tantric magic she had that could keep a man locked in ecstasy, and suddenly he knew that although he would always know he had done the right thing, he would also forever regret not having felt what the lucky son of a bitch next door was feeling in that moment.

And then the room service guy began to cry.

In the midst of his climactic groaning, he sobbed and began to say “please” every few seconds. The tone alone told Tim that the man wanted it to end. That he had had enough.

Diana laughed.

“Come on, baby,” she said. “Fuck me harder.”

Then it was her turn to moan, sounding the way some lovers did when they were locked in a deep kiss, or during oral sex. Tim’s erection had returned full force even as he listened with growing unease. The room service guy’s cries sounded full of pain now, even fear.

Tim reached out and turned on the light. Sitting up in bed, he stared at the wall, trying to decide what exactly he was hearing.

You’re to blame for what happens, Diana had said.

But what, exactly, was happening? This did not sound like sex anymore, not like ecstasy. And now that he thought about it, some of the groans the previous night had sounded full of pain to him as well. What the hell was the woman doing to this guy?

He picked up the phone and reached out to punch the button for the front desk, but hesitated. What the hell would he say? Instead, he put the phone back in its cradle and climbed from the bed. Tugging on the pants he had worn that day, he ran the whole thing over in his mind. He could bang on the wall or go out into the hall and knock on the door, but if he was wrong . . . if this was just extraordinary sex or some S&M thing he was too naïve to understand, he would feel foolish. And to Diana he would appear jealous and full of regret, and he did not want to give her that satisfaction.

Diana’s muffled moaning grew louder. The headboard kept banging, although if he was correct the rhythm seemed to have slowed. But in the midst of the man’s groaning, Tim felt certain now that he heard sobs and weeping.

That’s not pleasure.

Fully awake now, he went to the slider, unlocked it, and drew it open as quietly as possible. Hesitating only a moment, he went to the railing that separated his balcony from Diana’s and carefully threw his leg over, settling his weight on the railing a moment in order to shift his weight from one balcony to the next.

You’ll be arrested, he thought. Peeping Tom. Pervert. She’ll think you just wanted to see.

But such reservations did not stop him. Something was wrong. He could feel it in the rising of the small hairs on the back of his neck and the icy dread that raced through him as he crept across Diana’s balcony.

Her slider was open halfway. The crash of the surf on Santa Monica Beach, just behind him, covered any noise his bare feet might have made. He paused just outside the slider, hidden from within by the curtain hanging on the other side of the glass. But where the slider was open, the curtain had been drawn back to let moonlight into the room. Tim took a deep breath and held it, then carefully leaned in so that he could get a glimpse into the room.

Diana knelt astride an olive-skinned man, rocking herself back and forth on him, riding him hard enough to keep the headboard slamming the wall. The sensual curves of her body in the interplay between moonlight and shadows made Tim catch his breath. But then he noticed the way the man’s body bucked beneath her, the way his hips seemed to come up off the bed with her, not as if he were thrusting into her but as though with each motion she dragged him up with her, as though her sex had clamped onto him and tugged again and again, milking him, attached in some unfathomable way.

So entranced was he by the strangeness of that, and by the swaying of breasts, that at first he did not notice the strange wrongness of the shadows around her face. The man continued to cry out, his eyes rolled back to the whites, his cheeks looking sunken—Jesus, he looked sickly, how old was this guy? Diana had her mouth against his chest and at first Tim thought she must be licking his nipples or his skin, but then Diana shifted in the moonlight, drew her head back a bit, and Tim’s heart seized in his chest.

His mind tried to make sense of what he saw. He stared, breathless, as denial tried to fight back the horror and disgust and fear that filled him. Chills rippled across his body and his stomach churned. Bile roared up the back of his throat, and he had to force himself not to vomit.

Diana’s mouth was distended, stretched into a pale, blue-veined funnel attached to the man’s chest, right above his heart. Her lips trembled with a quiet suction, the skin around them glistening wetly, but he could hardly tear his eyes away from the disgusting proboscis that her face had become.
