The aged janitor's jowls quivered as he laughed his delight at discovering the troublemakers. That Granger girl and that Longbottom boy, engaged in unspeakable acts in the astronomy tower... they'd managed to keep their noses clean until then, which made Filch all the more excited that he'd be able to test out all his new "equipment" on fresh blood. He was, after all, getting tired of abusing the Weasley twins' bottoms, however young, firm and tender they were...

Neville looked over at Hermione nervously. He didn't like the looks of where Filch was taking them. The average detention room was on a higher floor. No one could hear them if anything were to happen in the depths of the castle.

Neville straightened his shirt over his protruding stomach with a trembling, clammy hand. It had taken weeks to get the courage to ask Hermione out, and now this happens. The only thing that could make it worse is if Snape were there.

Neville sighed and looked up at the hideous caretaker. This was going to be a long night, and he was still aroused from his previous actions.

Out of the corner of her eye, Hermione saw Neville glance at her, but she didn't look back.
The bushy-haired teen was to busy looking at Filch. The way his back arched into a graceful hump, his knobbly limp, and his ranking odour. All of these things would probably drive most people away, but not Hermione.

The poor girl was obviously smitten.
