No. Freakin'. Way.
She's actually doing it, while watching you sitting there. The Princess, the most powerful pony in Equestria is petting herself in front of you. And that sultry look in her eyes makes you wanna clop yourself, but you wouldn't dare, not in front of Celestia.
"Like what you're seeing, my daughter?" She says to you. You're not sure why she called you daughter, but you kinda like it. That, and the sight of her fully erect wings make you moist.
"Yes Princess." You say, keeping humble, keeping submissive.
"Head up," She commands, still stroking her dripping sex, "Eyes forward, back up straight. You are to keep your posture in order while watching me, is that understood?"
"Yes Princess." She's got you soaked. Her whole air of control, the total feeling of her command. And the knowledge that she could have you banished at a moment's notice, hell, she very well may be planning on it the moment she's done. Having you arrested and placed in her custody. Maybe she'd chain you up in her dungeon and flog you herself. Oh sweet Celestia, the thought of it-
"Eyes forward. I will not remind you again." She says. How she is able to keep such a straight face while clopping is beyond you, but then again she is a princess, she could be eaten out and give a speech at the same time. You silently wonder if that position is open.
"I'm sorry Celestia I-"
"Excuse me?" she says, feigning anger, "Who told you you call me Celestia? I will not accept such an apology, I believe punishment is in order."
"Yes Princess, of course Princess. I, I believe a ..."
She stamps one of her hooves, "Speak up, what do you have to say for yourself?"
"I believe a paddling would be sufficient."
Celestia smiles. Your response must have been just what she was hoping for, "Well if it's a paddling you want, then a paddling you shall have, my daughter. Come hither, and sit on my lap, press your bosom against mine."
You bow your head once, before climbing up onto her lap, laying your legs over hers. The sun Princess's hoof is the only thing separating your candy vags from touching. Her horn glows, and out of the corner of your eye you see the small medicine cabinet swing open. A small purple hairbrush levitates towards you, you feel the flat plastic press up against your rear. Her magic pulls your tail up, fully exposing your buttocks to her makeshift paddle.
"You may lean against me if you need, I'll be rough, but you'll like it." She says. She's close enough to you to whisper. You press your nose up against her soft neck and close your eyes, waiting for the first blow. The sound of the brush rushing through the air is punctuated with a hard THWAP. Your body springs up, and you cringe in pain, but you wouldn't stop for the world. The brush strikes again, and again, she's beating your soft butt raw.
"I hope this lesson is not wasted on you." She says in between strikes.
"No Princess, I'll le-UH! I'll learn!"
Tears are running down your eyes now, you push your face deeper into Celestia's chest. Suddenly, you feel a sharp, glorious pain in your ear, Celestia is chewing your ear. You can't wait another second, you slip your hoof between your legs and rub like you're trying to start a fire. One more blow from the paddle sets you off, and you squirt out into Celestia's crotch.
Oh sweet merciful Canterlot no, the realization hits you like a train, you just squirted your ruler with girljizz. You look up to Celestia, she's breathing heavily now, still stroking herself. Her exhausted smile shows no anger, if anything it's like she's commending you for squirting on her. It serves to entice you more. You feel frisky, and reach behind her to massage the base of her wings, and that does it. She comes like a bomb, gushing her royal fluid all over her own hoof. You slip off her lap, and kneel before your ruler.
"Open." You hear her, and open your eyes, "I said open, lick this off."
Her hoof is extended to you, covered in both of your cum. You wrap your lips around it, slurping messily, and she giggles at the feeling. Here you are, bowed down before your princess with a red, sore ass, licking cum off her hoof. You're in heaven.
Of course, this blissful moment can only last so long. It does end a bit abruptly though, when the bathroom door swings open. Standing there, horrified, is...
