Dragon Booty 2

Celestia was mildly surprised to feel her ass cheeks being parted, but let out a groan of surprise when she felt Spike's versatile tongue start tracing around the edge of her asshole. Spike got his face right in between the two masses of ass flesh before letting them go, his entire head almost enveloped in the thick warmth of her butt. He placed a big kiss directly on Celestia's asshole the started licking more firmly, Celestia was panting and her eyes were crossed, she had no idea that her ass was so sensitive and that it could provide so much pleasure. Spike liked the fact that while Luna had been in control of her actions during their session, Celestia was on the other end of the spectrum, a completely helpless yet willing victim to his sexually deviant whims.

Spike decided to up the ante a little and applying a little pressure, his tongue slid into her asshole. Celestia gasped, nothing had ever been up there before. Spike wiggled and swirled his tongue inside her back door, Celestia felt ambivalent about it, it was a weird alien sensation, but wasn't entirely unpleasant. Spike pulled his tongue out, it was time to fuck this bitch and fuck her hard, she had an ass of legendary proportions and he wasn't going to waste what could have been his only chance to do whatever he could to it. Spike kept her ass spread as he lined up his dick with her wet twitching hole, once his tip was pressed up against her rear entrance he let go of her cheeks, his dick disappearing from his vision, hidden in the comfortable soft pillows of the princess posterior.

Celestia knew what was coming, she turned to Spike and said "M-master... I... I've n-never had anything up... there, b-before..."

Spike smirked and said "Well then, I'd say it's time someone popped your anal cherry and got your ass accustomed to the exquisite feeling of being roughly fucked. Looks like I'm the dragon for that job" without a word of warning, Spike clapped his hand down on Celestia's hips and rammed his entire length up her ass. Celestia's eyes went wide and she was completely silent, Spike could feel the hot walls of her ass clenching on his cock, not used to anything being shoved so deeply inside. Spike began thrusting, he was only a few thrusts in when Celestia basically screamed and came harder than she had ever had in her entire life, spraying juices all over Spike's legs.

As he continued her orgasm didn't seem to stop, it was just a continuous tingling feeling that persisted and made her face adopt the classic "fucked silly" look as she gibbered and moaned. Spike's hips were clapping against her monstrous ass cheeks, they wobbled up and down as well as side to side, the unfortunate thing about the feeling and the visuals of this was that Spike probably wouldn't last very long. Desperate to make sure Celestia got the ass fucking of her life, he reached forward and tugged on her gigantic wings to get more leverage and power behind his thrusts.

It was all becoming too much for Celestia, her horn started reacting strangely, fizzing and sparking, popping with magic as her horn lit up periodically. Spike noticed this and couldn't believe what was happening, she was about to have a horngasm. The horngasm was a well known phenomenon among unicorn mares, it was tricky to trigger because the mare in question had to be in an extremely high state of arousal, Spike was convinced that Celestia was about to experience a horngasm for the first time, he was right. Celestia could sense what was happening to her horn but had no idea what exactly was causing it to react the way it was, all she knew was that it felt good.

Spike just kept fucking harder and harder, tugging on her wings, he really wanted her to get her first horngasm and tried to hold out as long as possible, Celestia clearly loved having her ass taken more than she could have ever anticipated. Suddenly her horn began shooting rainbow colored fireworks all around the room, random inanimate objects levitated, Celestia was literally screaming out loud with her royal Canterlot voice. As the fireworks subsided and objects settled back where they were, she had been temporarily drained of her magic and was fighting to remain conscious. Confident that he had given all he could possibly give, Spike opened the floodgates and an extremely large warm load was pumped into Celestia's quivering insides, he kept on thrusting until he was totally spent and felt his dick beginning to soften up.
