Amber stumbles off into another boxcar and wonders what awaits her going forward, "Oh geez! I sure do hope this trip works out and nothing silly happens!"
Something silly would, in fact, happen.
As the door to this new boxcar clicks shut, she notices ponies fleeing out the far end of said boxcar in a panicked hurry. She turns her gaze to the source of this commotion...
A strange bipedal creature who's body is covered by a green spandex costume and a what appears to be a formal suit over it flails his arms as he stumbles backwards from an incapacitated mare.
"THERE IS NO LOVE MORE SACRED AND PURE THAN THAT WHICH IS SHARED BETWEEN A MAN AND A MARE!"
His victim was a prissy, yellow-and-pink mare, that now lies stunned in a state of what appears to be prolonged orgasmic euphoria, her her eyes having rolled back as her wet tongue hangs outwards.
Amber finds herself alone in the boxcar as she desperately fiddles with the door, attempting to escape.
"Please, somepony help!" There is no reply.
Her pleas go unanswered as the frenzied man charges towards her, his feet loudly banging against the metal floor as he does so.
She withdraws backwards into the nearest corner, trembling in terror before the violent and rapacious charge suddenly stops.
Amber opens her eyes slightly...
"BOOP," the alien loudly cries!
Amber feels and overwhelming sense of euphoria as this strange creature's fingertip lightly presses her snoot. Uncontrollably, her marehood winks, her hind legs spray open despite it all.
She feels... She feels hot... Warm, wet heat building in her nethers and she can't help but buck uncontrollably against this intense heat, her hind legs kicking weakly.
The alien leers at her, his faced turned downed in what appears to be a predatory pose.
"Men and mares we're meant for each other," he hisses as he reveals his manhood.
Amber opens her mouth to protest, but she finds the soft, supple lips of this "man" have already met hers. He sucks and whirs his tongue about as Amber weakly resists.
The heat rises and Amber Sunset can't help but force her tongue to dance with his.
Now she bucks violently, as if her marehood itself demanded attention.
She immediately feels a shaft slowly begin to invade her marehood and she can't help but moan loudly. It's so wrong yet so right.
"My name is Anonymous and I'm a MAN," the alien breathily states, having reached full bore.
Between moans, Amber Sunset coils and releases herself, fully embracing this wonderful assault.
It's over in several minutes as Amber feels his member part her. She now feels oddly incomplete in its absence. She looks up only to be given a final kiss. And what a kiss it was...
This "Anonymous" gave her a final parting look of what appeared to be acknowledgement before leaping from an open window as trees blurred past.
"No," Amber thought. "Not yet!"
Two royal guards burst in from the far side of the cabin, their looks of determination turning into horror as they saw Amber.
One guard, a grey earth pony stallion, reluctantly approached her. "By Celestia! Are you okay?"
Amber grinned absent-mindedly as she met the stallion's gaze...
"There is no love more sacred and pure than that which is shared between a man and a mare," she states, blushing intensely.
