Twilight Sparkle, by nature, wasn’t a very suspicious pony. She’d always been genuinely surprised when Pinkie Pie played a prank on her, but even she couldn’t help but suspect something was up when she heard inexplicable noises coming from the treehouse’s basement – gears turning, as well as a series of clicks. Spike wasn’t home, so she went down to investigate herself, expecting yet another surprise party.

Instead, she saw nothing. Looking around the room, it seemed exactly as she left it – that is to say, full of books. “Pinkie Pie?”, she asked.

“Guess again”, said another voice from behind her. Before she could turn around, Twilight felt a sharp pain in her flank and drifted out of consciousness.

--

When she awoke, Twilight found herself tied up, in her own basement. She tried to remove the bonds via telekinesis, but nothing happened – her horn was covered in a magic-draining oil. But, maybe whoever had captured her wasn’t here – and this was her chance to escape. Twilight began to wiggle, to try to force herself across the floor to the door. Then perhaps she could get help.

A hoof wrapped around her before she’d barely gotten halfway across the room. After being spun around to face her captor, Twilight finally knew where it was that she recognized the voice from – it had been The Great and Powerful Trixie.

“Did you honestly think”, Trixie asked, a look of smugness on her face, “That you could hide from The Great and Powerful Trixie forever?”

“Trixie?”, asked Twilight, more surprised than worried. “What are you doing here?”

A hoof struck the purple pony in the mouth. “Twilight, you are to address The Great and Powerful Trixie by her full title.”

“Great and Powerful Trixie”, Twilight said while grimacing in both pain and disgust. “Why are you here?”

“The Great and Powerful Trixie is here for a single reason - she requires that you service her.”

Twilight only stared at her captor in confusion. Trixie only responded by smiling, and spreading her forelegs to reveal a massive and erect stallion cock.

Twilight recoiled in shock. “Trixie! What… what the hay!”

The cock-bearing pony didn’t say anything. Instead she simply pushed Twilight Sparkle flat onto her back, and pressed her muzzle into Twilight’s plump lower lips. “They taste”, she said in between slurps, “like candy.”

Despite how Great and Dexterous Trixie’s tongue was, Twilight still struggled. Maybe if she could get to a book, she could flip it open with her horn and then rub the oil on her horn off into the pages. Then she could use her magic to get away from Trixie. Still, despite her mental resistance, her body was starting to betray her. Love syrup was pooling up in her slit, and she could tell from the expression on Trixie’s face that she knew it too.

Giving Twilight only a few more licks, Trixie then lifted her head away from Twilight’s sex before guiding the tip of her phallus to the bound pony’s honeypot. “Witness the Great and Powerful Cock of Trixie!”, Trixie proclaimed as she began to thrust into Twilight.

No matter how much she wanted to escape, some bestial part of Twilight compelled her to push against Trixie, driving the Great and Powerful Stallion Cock deeper into her. Still, she knew she couldn’t lose focus. She needed to get to a book, and clean off her horn.

Trixie gave her no respite, and began to thrust even harder before a thoughtful look came onto her face. “The Great and Powerful Trixie knows a way to make this much more fun, for the both of us.”

Trixie’s horn lit up, and Twilight looked around to try to see what she’d done. There appeared beside them a gelatinous pink blob. As Trixie’s horn continued to glow, a few ropelike extensions grew out of the amorphous blob and started towards the bucking ponies.

“I’m certain you see what the Great and Powerful Trixie is planning?” was all Trixie had the chance to say before a slight pained look came onto her face. A pair of pink tentacles had slipped in between Trixie’s moist lips, while a third invaded the secret confines of her anus. As soon as she recovered, she continued to speak. “Three for Trixie. You’re a lucky pony, though. You get more.”

One slimy tentacle slipped into Twilight’s sex, Trixie smiling as the moistness cradled her stallion cock. A second entered Twilight’s anus, the pony closing one eye and grimacing as the tentacle pushed. A second tentacle then entered Twilight’s vagina as well, stretching it to its limit. Just as the shock of penetration was fading from Twilight’s face, one more tentacle slipped into her plothole.

By now, Twilight wasn’t thinking clearly at all. Trixie’s cock and a pair of tentacles were marauding her syrup hole, all three of them thrusting in and out and the tentacles changing size and shape. Two further tentacles caressed her plot from the inside, a feeling that she wasn’t used to. Still, if she could get to a book…

Trixie leaned down and pushed her tongue as deep into Twilight’s mouth as it would go. An eighth tentacles wrapping around the backs of the two ponies’ heads, pushing Trixie’s tongue in so deep that it nearly triggered Twilight’s gag reflex. She could feel an orgasm beginning to well up inside her.

Trixie lit her horn up once again, and four more tentacles moved in to rub against the ponies’ nipples. Suddenly, the tentacles – and Trixie – all pushed deeper into her, and she cried out in orgasm as best she could with Trixie’s tongue still in her.

Not 10 seconds later did Trixie withdraw her tongue and groan in orgasm. Her magic dick flooded Twilight with its magical toothpaste of love, and then she sighed once, withdrew all the tentacles, and rolled off of Twilight. Both ponies simply laid there for a while.

“Great and Powerful Trixie”, the Great and Powerful Trixie said to herself while lightly stroking her cock, “you were great.” Twilight apparently regained her senses before Trixie did – and she saw that the amorphous pink tentacle blob had reverted to an amorphous pink tentacle-less blob. Gathering up her remaining strength, Twilight threw herself at it – and her horn sunk into it, the mana-sinking oils coming off of her horn.

Trixie, seeing what was happening, tried desperately to pull Twilight out of the tentacle beast – but it was too late. Twilight had already shed the ropes binding her, and then placed a binding spell onto Trixie’s horn. A brace appeared around the base of the horn, stopping Trixie from using her own magic again.

Now panicked, the blue pony tried to run up the stairs before Twilight got revenge on her for what she’d just done. Twilight simply conjured up a length of wire for Trixie to trip on, before levitating her over to herself.

“Now, Trixie. What you’ve done wasn’t very nice at all.”

“Twilight!”, she begged. “Trixie is sorry! Let her go!”

“I think”, said Twilight, “you’re misunderstanding me. I want a turn too.”

And with that, Twilight’s horn began to glow, and with a flash of light, she grew a horsecock even larger than Trixie’s. Wrapping her forehooves around Trixie’s back, Twilight forced her tongue down into Trixie’s mouth before ramming her own enchanted phallus into Trixie’s moist sex. Trixie’s cock began to grow erect once again under Twilight’s weight – and Twilight’s horn lit up, causing Trixie’s erection to grow to an ever larger size. When it nudged against the ponies’ chins, Twilight lifted her head up to make clearance for the huge dick. It stopped growing just above Trixie’s mouth, and both ponies then began to lick the tip. Trixie shuddered in pleasure.

Twilight lit her horn up yet again, conjuring a number of magical vibrators from the ether. Stretched out by Trixie’s tentacle monster, Twilight levitated three vibrators into her toothpaste-filled hole, and another two into her plothole. Trixie’s plothole received the same treatment – two supernatural vibrators stretched her beyond her previous limit, causing her to recoil in pain, while a third vibrator found its way into her love canyon, causing Twilight to squirm in pleasure as it massaged the underside of her cock.

The sensations were too much for Twilight to bear. Her own crème-de-la-crème shot out of her otherworldly phallus, flooding Trixie’s insides. With her first male orgasm came a mental tension that caused her to push all the vibrators in deeper, before starting to withdraw them.

Twilight’s manwomanjuice and the vibrators brought Trixie to a second orgasm. She cried out as her cum-filled canyon pulsated around Twilight’s cock, and as her own dong squirted lovejuice over her face and a few of Twilight’s books lying on the ground.

Twilight didn’t even bother to withdraw her cock from Trixie, but instead lazily thrust in and out and licked Trixie’s lovejuice off of her face. Eventually, she simply rolled over onto her side.

“That was fun”, she said, exhausted. “Want to come back Wednesday?”

Trixie panted before responding. “Yeah”, she said. “The Great and Powerful Trixie might do that.”
