Nothing to do but watch the show

Digit puffed up her cheeks with a huff, annoyed that her brilliant plan had failed.

What should she do now? Try again with a different noise? That might work... but since Mordekai had already shrugged off one illusion, he'd likely be more suspicious of whatever came next. He might even twig on that the small creature who had recently alighted atop him might be the one responsible. That would not be a great start to their friendship.

And so, for now, her best option was probably to wait it out until Mordekai decided to move on his own. With a quiet sigh, she turned her attention back towards the couple on the porch. She primarily wanted to keep an eye on them, in case they spotted her. Not only that though, but once they finished what they were doing, she might hopefully be able to glean more context about who they both were, in relation to each other and/or to Digit herself.

Resting her arms on an antler and her chin on her arms, she settled in to watch the show. A firm grimace adorned her face; she'd never understood why people liked this sort of stuff...

The troll was now positioned on his back with the wolf girl slowly climbing atop him. He took her nipples into his mouth one at a time, suckling hard and making her moan like a whore in heat. Surely she had to be faking it; there's no way it could feel that good.

The troll's hands gripped the girl's hips, pushing down towards his own crotch. Digit didn't have a good view at this angle, but it was pretty obvious he was aiming to move onto the main course. The girl's hips moved down barely an inch, and she let out the loudest mewl of pleasure yet!

Ok, yep, definitely fake! Either that or she'd just orgasmed from the slightest penetration. Some people might claim that'd be perfectly normal if it was the girl's first time, but as a proud representative of the virgin committee herself, Digit would be eager to dispel that myth and save her comrades some dignity. She rolled her eyes and tilted her head to allow her cheek to rest lazily on her arms.

With a determined push, the troll brought the wolf-girl's hips down all the way to meet his, and they started fucking in earnest. From there it was fairly uneventful to describe: she bounced her hips against him. They both grunted. They moaned. They exclaimed all the platitudes about "how good it felt" that one might expect.

After a short while, the troll started to mash her hips against himself more forcefully, assumedly as he was approaching his limit. He gripped the girl's chin and said something to her that Digit couldn't make out, but the girl's response was impossible to miss. She may have been hamming it up before, but that all seemed downright tame compared to the screams she now unleashed!

Caught somewhat off-guard by the wail of the banshee, Digit reflexively clung to Mordekai's antlers in a moment of panic.
