After pinning him down on her chair, Celestia proceeded to rub Celestia's body up and down as she started grinding his dick. The next thing that happened, Celestia started kissing Spike as she continued to rub him with her body. Seeing his dick start to rise back up, she started grinding it with her pussy as she prepared for insertion. Celestia asks,

"Shall I put it in~?"

"Y-Yeah..." Spike responded.

Smiling, Celestia grabbed Spike's cock and inserted it. She was blushing and moaning as soon as it touched her womb.

"How does it feel being back inside your mother~?" Celestia asked.

"Feels... warm." Spike said.

"I'm glad you feel that way~. Because you're gonna burn up~."

Suddenly, she started moving her hips up and down as she french-kissed Spike. In a matter of seconds, she is gyrating as she started pumping him like a piston. The pleasure was so arousing they could barely think while fucking. Celestia was enjoying herself the most. All the work she had to put with in her duties did a number on her. She felt more than ready to have her way with Spike. Spike, on the other hand, felt very underhanded whenever Celestia took charge of their affairs. Whenever their promiscuous events would occur, Spike would always be tired to do anything. But given his position and being her son, he was under no obligation to say no. Especially not to the Sun Princess.

"Enjoying yourself~?" Celestia asked, albeit moaning.

"I'm having a ball." Spike said as he panted.

"Good~. Because I have even more planned for your trip~. So please cum~."

One minute later, Spike did as Celestia told him and he came inside her. Afterwards, Celestia got into a doggystyle position and said,

"Now make me proud of you, my cute dragon~."

Grabbing his dick, Spike started patting his dick on Celestia's ass so that he could hard again. Then unbeknownst to her, he proceeded to insert it into her asshole.

"Gah! Wrong hole, Spike~." Celestia said.

"Exactly..." Spike said.

He proceeded to thrust his hip as tears started to pour out of her eyes. Roughing hitting her butt as he thrusted, he started spanking her which aroused him even more.

"Your asshole feels so good, mom. It's so snug, warm, and tight." Spike said as he spanked her.

"Yes~. The way you dick is gaping my walls~..." Celestia said as her ass was being tapped.

Soon, Spike starting to feel more than ready to cum in Celestia's ass.

"Get ready, mom! It's gonna come out." Spike said.

"Go ahead, sweetie~." Celestia said as she moaned.

Seconds later, a second load was shot, filling Celestia's ass with Spike's semen. Spike fell on the ground, feeling exhausted from doing Celestia in her butt.

"Best sex I've had in awhile..." Spike said as he took a drink of bottled water.

Suddenly, Celestia wrapped his arms around him as he took a rest. Sweating nervously, Spike turned his head around and said,

"Mom?"

"I hope you enjoyed the little freebie~. Because the price for doing me in the ass has doubled~." Celestia said, leaning her head closer towards Spike.

Just then, she got off the ground and she picked Spike up in the process. Walking towards her bedroom, she locked all the doors, leaving no chance for Spike to escape.

"How are you able to recover this quickly? Your legs should be numb by now!" Spike said, shocked by Celestia's endurance.

"You always forget that I'm the Pillar of Marehood, Spike~. No matter how many times you come into me, I will always be too much mare for you to handle~." Celestia said, pinning Spike on her bed.

"Can't we at least have dinner first? Not even a show?"

Celestia went closer to Spike's left ear and whispered,

"Nope~."

Spike was nervous as to what was going to happen next. He already knew he was in hot water when he anally raped Celestia, but she was more sexually experienced and more in charge of their relationship. Not only did it feel demeaning, but it made him feel even more worthless as an assistant. Just then, Celestia said,

"Now give mommy some sugar~."

She proceeded to kiss him once more as they started to take various sexual positions while fucking. She raped and dominated Spike like he was an average filly. They fucked for various hours without end. Spike was beginning to run out of bodily fluids as they kept going. But Celestia kept going due to the fact that she wasn't sexually satisfied. But luckily by hour four, Celestia was ready to call in quits.

"Oh yes~. Please~. Give me your seed~!" Celestia begged.

Spike was reaching his limit as he had sex with Celestia, but like before, he was no position to say no to her. Holding back no longer, he fired his final load into Celestia's womb, finally filling her sexual appetite. Afterwards, she fell onto Spike, tackling him once more.

"Mmm~. You're the best~..." Celestia said, hugging Spike into her bosom.

Smelling Celestia after fucking her for so long, Spike said as he panted,

"Twilight doesn't call me her number one assistant for nothing..."

"She's telling the truth~. My own son servicing his mother in her time of need..."

"Yeah. When it's okay to be a nymphomaniac..."

Just then, Celestia started squeezing Spike into her bosom upon hearing that. After three minutes, Celestia let him go and she said,

"No back-talking your mother, Spike..." Celestia said in her tired voice.

Celestia snuggled Spike into her bosom as she started to fall asleep. She moaned as she closed her eyes, clutching Spike in her grip.

"It feels good to be back, mom. Even though it's still daytime..."

"Don't be silly, sweetie~... There will be time for dinner when Luna raises the moon~..."

Feeling the tightness of the grip around him, Spike tried to get out of Celestia's hug. But feeling him trying to escape, she said in her sleep,

"No, you don't~."

"Um... I was gonna use the bathroom."

"You can hold it~."

Having no other choice left, Spike listened to her and finally fell asleep with her.
