Cadence smiled. "What took you so long, Sombra," she asked, still on top of Luna, who had a slight worried look on her face. "I thought you'd be here sooner."

"I wanted to give you two some time together," Sombra said as he strode over to where the two mares lay and planted a kiss on Cadence's lips. He then looked at Luna. "Having fun?" he asked.

"Uh, yes," Luna said sheepishly, which got a small chuckle from Cadence, who got up off Luna and stood up on the floor.

"Don't worry, Luna," she said, her rack hanging free. "He actually had a fantasy of walking in on me doing it with another mare.

"And bucking her until she can't walk," Flitter said, taking off her light blue, skin tight leotard. "That's how we started. I was drunk, Queen Cadence was drunk, we did it, King Sombra walked in, and, well, we've been doing this since then." Flitter slid her leotard down to her feet, revealing her small but perky breasts and wet slit. She kicked it to the side, and walked over to Cadence, who put her arms around her shoulders. "Hey, Cadence," she said. "Missed you." Flitter placed her own hands on Cadence's plot. "And I especially missed these."

"I missed you too, Flitter," Cadence said, kissing the other mare as her husband began to strip and walk over to Luna, her mouth agape at the sight before her.

What she saw was a large member, about nine inches long, ans four wide. It was, with out a doubt, the largest cock Luna had ever seen in her life. "Like what you see," he asked, to which Luna could only nod. "I thought you would," he said as he lined himself up with Luna's wet slit. He pushed against it slowly, and entered, earning a moan from Luna.

"Oh, yes, Sombra," Luna said as Cadence and Flitter made their way to the shower room. "Please, buck me and make me your sex toy."

"No," Sombra said. "I don't do this for the fun of it, Luna. I do this only when I have feelings for a mare."

"So that means," Luna asked, Sombra still in her but not moving.

"Yes," he said, smiling. "Just like Cadence, I do have feelings for you, Luna. I'm just not that good at saying it."

"Then let's make love right here," Luna said. "I'll admit, you are a handsome stallion, Sombra."

"Thank you, Luna," he said as he began to thrust, filling Luna to the hilt and causing her to moan.

"Ohhh, yeeeeesssss," she said. "It feels perfect." Indeed, for Luna, it was perfect. It filled her  just right, and stretched her lower lips to a degree that wasn't painful, but comfortable. "Faster, please, Sombra."

Sombra said nothing, only increased the frequency of his thrusts, causing Luna to moan even louder. "Ohh, yes," she nearly yelled, playing with her mounds. "This is the best bucking I've ever had, Sombra," she said.

"I'm glad you think so," he said as he leaned down and gave Luna a small kiss. "It's a shame, then, that Cadence and Flitter decided to shower together, then."

"Why?" Luna asked.

"Because the two of them can do wonders together," he said. "I speak from personal experience, there."

"I can imagine," Luna said just as Sombra gave a particularly hard thrust, making Luna arch her back and moan. "Ah," she gasped. "Oh, yes, right there, Sombra. Faster, please."

Sombra further increased the tempo, now making one of Luna's moans and/or gasps of pleasure indistinguishable from the previous. Eventually, he said, "I'm about to cum, Luna!"

"Cum in me," she said. "Please, I want to have a child with you, Sombra."

"Whatever you want, Luna," he said just before he released his seed in the lunar alicorn. Once he had finished, he pulled out of Luna, and laid beside her.

"I do wonder what Twilight will think of this," Luna said.

"Knowing her, a mix of anger and happiness, anger being mixed with surprise."

"Why anger," Luna asked.

"Because when she found out about what happened with Flitter, who was in her early twenties when it happened, by the way," Sombra said, "Twilight nearly exploded at not being told, and I quote, 'having a new mommy'." Sombra chuckled. "Funny thing is, though, she was sixteen then."

"I fail to see the humor there," Luna said. "I imagine I'd have to have been there."

"That's right on the dot," Cadence, coming out of the shower room with Flitter behind her, said. The two mares laid down on the bed, sandwiching Luna and Sombra. "She had never called me 'mommy'. Mom and mother, yeah, but not that, and same with the male equivalents for Sombra."

"Now I see he humor, but only barely," Luna said, chuckling. "Wait, did she walk in on you three?"

"Nope," Flitter said. "Next morning, with us having our underwear on."

"To be fair, though," Cadence said, "she and Surprise had been dating at that time, and she had, when she was six, accidentally walked in on Sombra and I. So she probably knew what was going on, any way."

"It's a thousand years too late to think back to that detail," Sombra said. He sighed, closing his eyes. "Well, good night, everypony." With that he closed his eyes, and began to sleep.

"Good night, my husband," Cadence said, wrapping her arms around him and doing the same.

Flitter had already gone out here, leaving only Luna awake, but only barely. As her eyes closed, she felt, for the first time in years ever since her return, truly happy. Next Chapter: Betrayl Estimated time remaining: 11 Minutes
