As she walked into the room, Cadance eyed her husband suspiciously. “Shining… what have you been doing?”

Shining Armor looked back. “What?”

“What. Have you. Been doing?” Cadance repeated herself. “Chrysalis has been growing, and abnormally fast for a supposedly fully-grown changeling. She only feeds on love. So I have to ask… what have you been doing with her?”

Shining gulped nervously, but before he could answer, another pony walked into the room and gave her brother a deadpan stare. “Shining… why is Chrysalis so big?”

“I…”

“She wasn’t this big when I dropped her off for the Changeling Exchange Program, Shining,” Twilight said suspiciously. “Why is she like that now?”

Shining gulped again. “I…”

Both mares gave him a look, and he finally groaned. “It’s not my fault! Not… entirely, at least.”

Both mares stared at him even more intently, and he sighed. “I found out she’s a voyeur who likes spying on us through our windows when we’re having fun!” He bowed his head. “Since then… I’ve just made it easier on her by making sure the curtains aren’t shut then.”

Cadance opened her mouth and shut it several times, when suddenly another mare’s voice cut in.

“It’s true,” the voice said, and then Chrysalis calmly walked in. “I’d love to spend some one-on-one time with him, but he always turns me down. That’s why I started peeking through your windows instead.” She smiled. “I like how you two make some of the cutest noises during your private time… plus, all that love you give off? It’s as delicious as what I’ve been told ice cream tastes like!”

Cadance eyed her for a bit, then sighed. “…I can live with that.”

“Then you aren’t mad at him anymore?” Chrysalis asked. “He didn’t cheat, after all… he’s just an enabler for my voyeur habit.”

“…No, I’m not mad.” Cadance sighed again, before grinning. “I just wish he’d have told me you were watching us. If I’d known, I’d have put on more of a show!”

Twilight chuckled. “That’s my sister-in-law,” she said teasingly. “Ever the exhibitionist.”

Chrysalis moved in and nuzzled Cadance. “And of course, if you want to have some one-on-one time with me… or two-on-one… or more… I’m always available.”

Cadance smiled. “I think we can arrange that,” she said, and nuzzled Chrysalis back. “Coming, Shining? Twilight?”

Both ponies immediately grinned.

Is it bad I want to imagine Flurry Heart making that face too while holding and egg she found.
“Father why bug make egg father?”
