Polyamory

~~Thorax~~ Crystal Hoof couldn't believe what he was hearing. He had been gone for a few days visiting ~~Queen Chrysalis to report in~~ his grandparents for normal family activities. When he got back, his husband had a very interesting story to tell.

"So she took you and Dark Thrust to the same place where we go..." Crystal quirked an eyebrow. This was a lot for Crystal to take in. Much like Spear was.

"Yep!" ~~Doomie~~ Gleaming Spear confirmed. He grinned like Rainbow Dash in a shower full of Wonderbolts.

"And then... the rulers of the Crystal Empire showed up?" Crystal asked. "This just happened?"

Crystal leaned down and looked beneath Spear. He was still hard. And slick. Oh morphic gods he was serious.

"Uh-huh," Spear was so giddy that he was bouncing, his dick flopping humorously.

"And then... Cadance blew you... to lubricate you so you could fuck Luna up the ass. Then Luna fucked half a dozen other guards. Then you again. Then the other guards again." Crystal stared, "Oh, and Luna let Prince Shining Armor impregnate her."

"That's right!" Spear chuckled, "Can you believe it? You think Mom will even believe it?"

"Wow,” Crystal blinked, "First that weird offer from the crystal princess and now this... I sorta hope Mom takes the offer. I haven't even gotten to fuck a pony, much less an alicorn. Much less two alicorns!"

"That's ‘cause you bitched out during the invasion," smirked Spear. "While I was busy doing the pink one. In every hole. Twice."

"I still don't think that's what she meant when she yelled 'Do me'," huffed Crystal, so very jealous.

Crystal suffered an identity crisis during the Canterlot battle. Now the more time he spent as an agent with ponies, the more he wanted to get to know one as his true self. He figured that he’d have a better chance of that as the stay-at-home husband, but clearly he should have chosen the other role.

"She didn't complain!" Spear laughed, but all the same seemed empathetic when he picked up Crystal’s mood. "Aw don't be like that, sweetheart. How about you be Spear for a week or so, maybe she'll put out again?"

"I don't know enough about him," lamented Crystal. He’d spent too much time trying to get to know ponies and not enough time studying his mission.

"Well you could always get an indirect go if I bang you while I'm still coated with her juice," winked Spear. "Take your true form, we can role-play that I caught you!"

"Fine." Crystal rolled his eyes, returning to his true form in a flash of green magic. “Only because you’re my hottest brother.”

A knock on the door made them both jump.

"Say who what?" Thorax looked at the door. No one ever visited them at this hour.

Spear peaked out the peep-hole, then looked back with wide eyes, "It's the crystal princess!"

"Think she knows?" Thorax felt panic well up, heart thumping.

"Don't be stupid," Spear rolled his eyes. "She's probably here cause my cock tasted so good. You know what she can be like."

"I WISH I knew what she could be like!" growled Thorax.

Another knock.

Thorax stepped back as Spear opened the door.

"Princess!" Spear feigned complete surprise and bowed, "I... didn't expect you!"

"Oh don't be like that. You’re off-duty," chuckled Cadance, "Mmmm... you're hard… Oh and that would explain it. Is that your husband back there? Hello Spear's husband! You don’t mind that he nailed two princesses, do you?"

Thorax waved and shook his head. So awkward. He felt like he was forgetting something though. Hmm, wonder what it was.

"I'll be brief, sweeties." Cadance smiled. "Luna and Shining mentioned that you cuties were gay. Since me and Shiny are still in Canterlot, I wondered if you'd like to drop by the palace after your shift on Friday?" She paused for a moment and then added. "To bang my husband, in case that wasn't clear. Your mate can join in!"

"R-really?" Spear blinked.

"Really!" laughed Cadance, then added more quietly, "You have a huge dick. Way bigger than Shining’s."

"Sure?" Spear barely got the word out.

"Great!" Cadance smiled, "See you about say... ten? For now, I'll leave you two hot boy toys to your scheming." With that, leaned in to give him a peck on the cheek before bouncing off on her way.

"Huh, wonder what she meant by scheming," Spear scratched his mane as he turned around. He stared at Thorax with an open muzzle.

"What?" Thorax asked.

"Thorax... bro..." said Spear breathlessly, "You forgot to retake your pony form... she saw that you were a changeling."

"... Fuck."

"Does this mean we aren't gonna fuck?" sighed Spear.

"Why would it mean that?" Thorax chuckled.
