There once was a dragon named Spike
Who wished Rarity was a bike
That way he could ride her
(With flowers he'd plied her,
But she might as well've been a dyke.)

So now he saw an opportunity
In her service to the community
To finally do her,
But he wouldn't screw her
No she would screw him with impunity.

"Yes this is worth it!" he squealed,
As she rammed it up his happy meal
The dragon rejoiced
as the moans filled his voice
For it seems pegging still held appeal.

He never did stick it inside her
but as he lay panting beside her
He diddled his meat
While she pounded his seat
Stretching his virgin ass ever wider.

Note: Assume Spike is 18. Dragons just mature slowly.
