Well, ten points to Gryffindor because I actually managed to keep my promise. Not bad. I also typed up a scene, which, though I loved writing, didn't have any place in the actual story. Not to mention that it's humor of a raunchy variety and I didn't want to put too much of that in there. So I figured I'd go ahead, stick it in a blog post and here we are.

Caution: The following scene, is non-canonical, non-coherent, and non-sensical. You have been warned.

“Oh my goodness! It’s so big.”

Twilight paused just before knocking on the door to her guest room. That had been Rarity’s voice, muffing slightly thanks to the thick door between them, but Twilight had no trouble identifying it as her friend’s. A friend who had shown open interest in Blackstone and was now alone with him in his room.

Twilight shook her head. She’d already jumped to the wrong conclusion after that scene with Pinkie. Rarity was probably talking about his coat or some other object. It was ridiculous to assume that whatever was happening in there was improper.

Blackstone chuckled. “Yeah the size is impressive, but how you use it is what’s important. Want a demonstration?”

Obviously talking about an object, maybe a new staff or some other magical item. Absolutely nothing wrong with this. Twilight told herself. If her mind weren’t so adamant about remaining in the gutter she wouldn’t have imagined a faint rumble of arousal in Blackstone’s voice.

“Oh, yes!” Rarity replied in a voice more sultry than Twilight had ever heard from her. Creaking bed springs soon followed the reply, and the purple unicorn was finding it harder and harder to justify what she was hearing.

“Oh sweet mother of Celestia that feels amazing!” Rarity cried less than a minute into … their activity. Twilight reached for her last excuse, the only possible thing that might explain this other than the obvious conclusion.

Maybe he’s giving her a massage?

Blackstone gave a wordless grunt, the same sound any health virile stallion would give when he was …

Giving a really deep tissue massage?

“Oh, Blackstone!” Rarity screamed. “This is the best sex I’ve ever had!”

Twilight’s jaw dropped open, and a crimson flush spread across her face. For a moment she considered running away from that terrible door and never mentioning this to anypony, but then the anger came. This time there was no denying what had happened. This time Pinkie was not going to save him from the fate he so richly deserved.

A burst of magic tore itself from her horn and the door slammed open, leaving a huge dent and a spider web of cracks in the wall behind it. Twilight levitated into the room her eyes on fire, ready to deliver her righteous judgment and wrath upon the lecherous stallion.

Only to find the room, and bed, empty. The sole occupant of the room and the one apparently responsible for the sounds she’d been hearing grinned at her from the dresser.

“So,” Bob leered, “how’d you like the show?”

His screams echoed throughout the library for the next hour, and it would be an understatement to call them ‘soul-chilling’.
