Spike allowed his cock to slip out of Celestia's ass, both of them breathing heavily. Spike said "I assume... you approve of... my skills?"

There was a long pause before Celestia said "Very much master... thank you...". With an answer like that, Spike didn't know what else he could do but just leave her to bask in her afterglow. As he started walking to the door to leave, Celestia quickly went "Wait!"

Spike turned to her with a quizzical look on his face, Celestia said "Before you go... do you have any wishes master?" She was smiling sweetly with a thin veil of innocence in an attempt to hide the slut beneath.

Spike smiled mischievously and said "As a matter of fact, yes. I wish for us to do this again sometime". Celestia giggled and laid down on her bed for a well deserved rest, Spike leaving to return home.

-meanwhile-

Twilight cut off her spell, she was lucky that her handy music box spell hadn't been noticed by either of them. She had seen everything that Spike and Celestia had done in that room, but rather than feel disgusted or shocked, she just felt betrayed more than anything. Why had Spike lied to her? Though, more importantly, if he was so desperate to get some ass action... why didn't he approach her about it?

The End

Author's Note

For those of you who asked for it, here it is! I hope you enjoyed it :) I know some people might have been expecting or wanting Twilight to get involved, but it didn't seem like something I could have added in this story. Don't worry, as you can see I've left it open for a possible third installment which will feature Twilight if anyone wants it. Let me know!
