Parvati snapped awake mere seconds after she had finally managed to fall asleep. This was the second time in two days this had happened, but it wasn't coincidence. Some time last month, Parvati had woken from a bad dream, and, in the process of writing it down in her Dream Journal for later interpretation (even bad dreams could be used to divine the future), she noticed that Hermione was gone. Snuck out, her wand left behind. Hermione sneaking out was not unusual-Potter did that a lot, and it seemed like whatever Harry Potter did, Hermione and Ron Weasley did also. What was odd was Hermine leaving her wand behind. Parvati was filled to bursting with curiosity, and resolved to find out why the girl had left herself so vulnerable. So, unbeknownst to Hermione, Parvati cast a Tripping Line Charm on the dormitory door, which would alert her instantly if someone crossed it. It had woken her up last night as well, but before Parvati could stop her, Hermione had cast the Disillusionment Charm on herself, and done an excellent job, for Parvati had been unable to track her. Because of that, Parvati rushed out of bed and to the door, just in time to see Hermione rush down the stairs, still visible. Parvati made to follow her, but in a split second knew that that was a bad idea.
Two days ago, she and Lavender had had tea, something the two did regularly. While reading her tea leaves, she had seen the Thief and the Procrastinator. It was rare to see two such opposing signs with tea leaves. You see, the Thief was a sign that good fortune would come from following someone close to you, but the Procrastinator was a sign that instincts should not be followed immediately. The combination had puzzled Parvati to no end, but now she understood. And so she waited for a short while, squatted down against the door of her dormitory, still in her pajamas.
After a short while, it occurred to Parvati that she should at least watch the Common Room to see if Hermione left the Tower or not while she waited, so she quietly walked down the girl's stairs to the bridge overlooking the Common Room and looked down. There, to her surprise, was Hermione, sitting in her sleeping gown on the hearth, her back to the low fire.
Parvati's brow furrowed in confusion. What was she doing? Then, to Parvati's utter shock, she heard Potter's voice.
"Are you ok?"
"Yes, Master, why?"
Master? What did Hermione mean by that?
"I...I'm just concerned for you, is all. I mean...that's some pretty big news we got this morning."
"Wonderful news, Master. News that I've been hoping to get for a long time."
Now Parvati was well and truly confused. What news? What were they talking about?
Hermione seemed to consider her next statement for a second. "You know, I know the Pregnancy Protection Charm. Known it since you first started seeing me as a woman rather than a friend. But I've never used it, not once in the two or so years that we've been coupling."
"You mean fucking like sex-starved rabbits."
Parvati's eyes widened to the size of saucers when she heard this, and she blushed profusely. What had she walked in on?!
"Right. My point is that I'm thrilled to be having your baby. I couldn't be happier!"
Parvati's eyes went, if possible, even wider. Hermione was pregnant?! With Potter's baby?!
"Really?"
From her vantage point, Parvati could see Hermione nod enthusiastically. Then she heard an odd sound from the chair that Parvati was sure Potter was sitting in, although she couldn't see him. Was it...patting?
Hermione removed her sleeping gown, leaving her in just the collar that she had taken to wearing, and Parvati was, as seemed the theme for this night, totally shocked. Hermione, naked in the Common Room! PREGNANT Hermione, naked in the Common Room! Then Hermione crawled--crawled!!!--over to the chair Potter was sitting in, and shortly after that climb up to straddle his lap.
At this point, Parvati realized what was about to happen. As Potter attacked Hermione's lips with her own, Parvati felt an odd mixture: arousal combined with the urge to run away screaming. Parvati knew that she shouldn't watch this. But she also knew that what she was seeing was the hottest thing she had even seen, and gods help her, she couldn't bring herself to leave. It was upon this realization that she knew what she wanted, what her body wanted. She slid a hand down the front of her pajama bottoms.
"I'm sorry Master, I just...I want you so much..."
Parvati was startled by the unexpected voice, and her knee thumped against the ground hard, making a sound that she was sure was heard by the entire Tower. Her heart pounding like a blacksmith at an anvil, she ducked, listening desperately, muscles tensed to flee if she heard the sounds of Hermione and Potter coming to investigate. But no...
"Is that right?" Potter asked, and then Hermione hissed softly, but still loud enough for Parvati to hear. Parvati peaked out over the edge of the banister, and saw Hermione squirming, Potter's hand between her legs from behind. The sight--the totally, unbelievably HOT sight--reminded Parvati of her own feelings, and her hand returned to her own snatch. She rubbed herself, her fingers tangling in her bush. Parvati whimpered slightly when she saw Potter actually taste his finger. "So that's how it is, is it?"
"Yes, Master..." Hermione answered, breathless.
"Yes, Master..." Parvati echoed silently.
Potter then whispered something into Hermione's ear, which literally drove Hermione insane with desire. The girl attacked Potter's lap, and soon she freed Potter's cock.
Parvati stared at it. The thing was at least 7 inches long!!!! It was huge, a monster! And despite the fact that she had never so much as kissed a boy before, Parvati had to fight down the desire to leap from the bridge and beg to have that wonderfully big cock inside her.
Parvati's view was obscured when Hermione sat on Potter's cock, riding it as though she hadn't had sex in a month. Hermione's face became a picture of dirty, slutty bliss, and Parvati realized that she was fingering herself, and then realized that her face was a mirror image of Hermione's, her mouth open, eyes hooded, panting slightly. It was as though she could feel Hermione's pleasure secondhand. For a couple of minutes this continued, Hermione riding Potter's hard cock as though she wanted nothing more in the world, Parvati's fingers (three of them now, more than she had ever had in herself) matching Hermione's pace. Just as Parvati was beginning to feel the fire inside her reach a fever pitch, Hermione spoke again, a throaty plea:
"Master...Master, please...finger my ass!..."
Parvati's eyes snapped shut. No, no she couldn't! That was..that was dirty, filthy! Yet deny it all she tried, she couldn't lie to herself. Now that Hermione had said it, Parvati wanted nothing more than to experience the sensation herself. As Potter snaked his hand down Hermione's back, Parvati slid her own free hand down behind her, and when Hermione moaned obscenely loudly, signalling that Potter had done it, Parvati slid her own finger into her ass.
Immediately Parvati came hard, having to clench her teeth to keep from screaming in pleasure. Her body rocked in bliss, her waves crashing her against the rocks of decency until she was little more than a very tired bundle of nerves, her fingers still in both of her holes. Her breath came in silent gasps, her mind still present enough to know to keep silent, lest her actions become known. Absently she heard Hermione moaning loudly into Potter's mouth, and Parvati knew the girl had cum, probably as hard as she herself had. In a moment Parvati quietly got up to go to the bathroom...she needed to clean herself up, lest Hermione smell Parvati's arousal when she returned to their dorm.
While she was cleaning herself, Parvati came to a decision. Whatever the cost, Parvati had to join with them. Even if she had to let Potter...become her Master.
