Sombra inhaled sharply at the feeling of his ass being squeezed by Cadance. He wasn't sure how to really respond; it didn't help that she was rubbing her thigh up against his balls, or Shining was watching with a grin.

"So, Sombry. Did it feel good?" She asked, pressing her breasts against him.

"Wh...what?" He blinked, twitching at the light smack on his left asscheek.

"When you had your hole full of Shining's meat." She smirked at the faint hint of pink appearing on his cheeks. "I bet he stretched you out good, didn't he?"

"I-I..." He inhaled as her hand replaced the thigh, rolling his scrotum in her palm. A glance to Shining showed the unicorn was just sitting there, watching calmly.

"Considering Junior's already saying hi, I'll take that as a yes." She said, both on them looking down as his rapidly growing erection. "Now, since you know what's in store for you, we've decide it's the perfect time for your first lesson."

"Why does that sound ominous coming you, Cadance...?" He said.

"Ah-ah-ah." She gave his balls a gentle slap. "From now on, it's 'Mistress'. Though. 'Mommy' is a fun alternative. Now, like we said, since you get to be our new playmate, it's time you looked, and dressed the part." Her horn shimmered, and an elegant jewelry box appeared in her hand. "I take it you've never worn jewelry before."

"I had a ring once." He admitted. "But that was a long time ago."

Shining smirked as Cadance opened it. "Well then, you're in for a treat."

His face reddened when he saw the contents. They were planning on him wearing that? "W-wheres the rest of it?"

Her smile told him everything. Sombra gulped slightly; there was barely anything there! How'd they expect him to walk around in that??

...and why did it seem to to turn him on for some reason?

"First lesson; to play the part, we need to dress you in the part! Let's work our way down, shall we? Shining, care to give me a hand?" She asked, floating the box beside her.

"By all means." He got up, giving Sombra a clear view of the bulge he already had. The two proceeded to take out bracelets and an armlet, using a few spells to phase them through the chains and onto him, along with a collar.

'Say, Sombry, I'm curious, which do you like more; cock or pussy?"

"W-what?" He looked at the mare. "What kind of question is...?"

"A simple one." Cadance replied as she wrapped a belly chain around him. "You prefer a snug, tight slit, or a big meaty dick? It's mostly out of curiosity. And what to reward you with if your good."

"Um...I...I don't know..." He answered in a low tone. Which was more or less true; given Shining had been his first time with another stallion.

"Ah, no big deal then." She shrugged. "We'll work it out as we go. Besides, me and Shining like both, anyway."

'You...you do?" Sombra blinked, then squeaked when Shining grabbed his semi-hard shaft and started stroking.

"Getting you ready for the next piece." He grinned, pumping him steadily until he was fully hard, then gripping his scrotum.

"Heh, you always like going for the plums." Cadance shook her head as she pulled out something that looked like two rings attached by chains.

"Gets the message across." He replied. "You have no idea how quick that wakes up a guard sleeping at his post."

"Noted..." Sombra moaned slightly at the feel of his balls being rolled around, along with Cadance grasping his shaft to slide the rings on.

"Someone's enjoying himself." She added, putting one ring at his base and the second halfway on his cock, twisting it so the chains connecting them spiraled before they shrunk to fit. "Feel ok?"

"A... a little snug, but otherwise; what's the longer chain...for?" He stopped when the one connect to the base ring showed it separated into three. Two that Shining looped around his sack while Cadance threaded the central through the loop so it went between his testicles, forming a barebones pouch. "Oh."

They then slipped something resembling a garter onto his left thigh, then anklets. By the time the were done, Sombra was feeling a bit like a harem dancer. "I think that's enough for now, we can add the piercings later."

"Piercings??" Sombra refused to admit he sounded startled, especially since she said it in plural.

"Don't worry. it'll be painless. Magic, remember?"

"Oh...right." He looked at all he had on now. "So...what next?"

Author's Note

I know, not my best, but given how long it took me to get this thing done, I figure might as well.

You guys wanna see Cadance have a turn with him, or doubleteam?
