"Oh Radius, yes!" Celestia gasped blissfully as her coltfriend passionately made love to her after a date at a Canterlot opera house. "Yes! Oh Radius, don't stop! Oh my g-ahh! Hahhh...hahhh..."

"Ooohh yeahhh, Celestia, my darling!" Doctor Radius Hoofenschtov moaned as he thrust in and out of the mare he loved, both of them teetering close to the brink of orgasm. "Oh Tia, I thi-guh! I-I think I'm almost th-*huff!* Almost there!"

Princess Celestia and her lover, Doctor Hoofenschotv had secretly dated for the past year and a half and tonight was the first time they had both appeared together in public. In the past, it was considered rather improper for royalty to form romantic relationships with ponies who were considered commoners by the standards of the elite. It was especially taboo to engage in intercourse outside of wedlock, however, this idea was now considered outdated as the turn of the century and the new millennium was a mere fourteen years away. This was the spring of the year 1986 and the ever changing times were paving the way for more modern ways of thinking and the freedom for anypony to love whomever they wished.

Though he was not a noble or member of royalty, Radius was by no means a commoner by realistic standards. Only to those with political pull, according to their unreasonable ways of thinking was he just an average unicorn. With an IQ of one hundred ninety-seven however, he was indeed not average. Aside from his superb intelligence, many would ask what somepony as regal and royal as Princess Celestia saw in him past his large, thick framed glasses and tacky bowtie. By no means was he a bad looking stallion but he was incredibly awkward and as long as he could remember, had difficulties with social interactions.

Radius was like many who were often referred to as "nerds","geeks","dorks", and the like. For most of his life he was the shy, quirky type whom had little to no luck with wooing mares. That was until he received an invitation to the Grand Galloping Gala of 1984 and would find himself meeting Princess Celestia in person. Celestia, being drawn to him by his intelligence and classy personality was the one to break the ice to engage in conversation and ended up spending time with Radius throughout the entire event. The two quickly became close friends over the next few months and that is when Celestia invited him to dinner at the Royal Canterlot Palace and made the first move.

Despite his genius level intelligence, he did not immediately catch on to the fact that the princess of all beings was courting him. In fact, his obliviousness soon left Celestia quite frustrated and gave her little choice but to be more up front about it. The Doctor was not much for picking up on such cues but If there was something she truly wanted in a stallion, it was his smarts, his class and over all, his kindness. Not to mention she also admittedly could not help but adore his shyness as it simply gave him that charm about him that she found difficult to ignore. With a regal princess vying for his attention however, it would prove difficult for one to not be apprehensive at first. While most mares preferred a stallion with popularity, muscles and bits to throw around, Celestia was anything but superficial and could not care less about those things; though Radius did earn quite the substantial salary in his line of work.

"Ahh! Tia! I th-think I-I'm gonna...!" Radius screamed as he neared his peak, his entire body throbbing with every beat of his heart. "I'm co-aaahhhh! Haaahhh! Haaahhh!"

"Radius, oh my god, yes!" Celestia screamed as she reached her own orgasm. "I'm almost...hnnggg!...ahhh!"

Finally the couple reached the point of no return and everything went hazy as their bodies throbbed and the two collapsed onto each other and lay there as they tried to catch their breath. As they lay there gasping for air, they enjoyed what they felt was the best part of their time together which was simply holding each other close to feel the warmth of their bodies against one another. For the loving couple of lovestruck ponies, their lovemaking session like all their others before it was pure, unadulterated bliss.

This was not their first time having engaged in intercourse with each other as they enjoyed their first time as a couple three months into their relationship. For Doctor Hoofenschtov, his first time with Celestia was his first time ever giving her the honor of having taken his virginity at the tender age of thirty-four. Over a year after their relationship began, they were still going strong and becoming even closer by the day. There was simply no denying it. The two ponies were in love and were not planning on keeping it a secret much longer.

"Hey Tia." Radius cooed as he playfully nibbled Celestia's ear.

"Yes, dear?" Celestia answered, her eyes half lidded as she looked into those of her lover.

"Love you."

"Love you more."

"Nuh-uh."

"Oh whatever, you know we just can't get enough of each other. My god, every time we do this, I just feel another hundred years younger!"

"And yet you don't look a day over twenty-five. I swear, I can't stop forgetting that I'm in love with somepony who's been around this long. I keep thinking you're ten years younger than me."

"Aww, you always know just what to say. I love this new confidence you have though! I'm telling you, darling this is the most passionate you've ever been! I don't know what's gotten into you but I like it!"

Like most stallions who had little to no luck with mares, Radius also once had little confidence and self esteem. Over time, his relationship with Celestia completely changed him. Gone was the meek, lonely, withdrawn Radius who kept to himself as he had transformed into an upstanding, proud social butterfly. He and Celestia simply made each other happier than either of them had been in a very long time.

"Thanks, sweetheart." Radius said in response to Celestia's compliment. "So, uh...I kinda wanted to talk to you about something. You know, our big revealing that we're dating and all."

"Uh huh. What about it, dear?" Celestia asked. "I mean, we've already been out in public together tonight so it's not like it's completely under wraps anymore."

"Yeah, I was a little apprehensive about it at first but I thought about it a lot more. I say I'm ready when you are. I feel like I want the whole world to know how happy I am!"

"Aww, me too! I love you Radius!"

"And I love you too Tia!"

Celestia and Radius had discussed their readiness to come out to the public and reveal that they were a couple many times and finally felt that they were ready to do so. They ultimately decided that they would take a somewhat slow approach to it at first by simply showing up in public settings together more often just to get the gossip started. Soon, all of Equestria and beyond would know of Princess Celestia and Doctor Radius Hoofenschtov, the happiest couple with nothing to hide and everything to show.

"So, I was thinking tomorrow we cou-" Celestia began before stopping herself. "Oh that's right, I forgot. You were taking that trip to Earth tomorrow, right?"

"Yeah, the Soviet Government asked me to help out with this test they plan on doing at that Chernobyl plant in Ukraine." Radius answered. "Though I'll be honest, I'm pretty miffed about that overseer running the place. Uh, Anatoly Dyatlov's his name. The guy's pretty reckless and I have half a mind to report him again. I've got a bad feeling about him being in charge."

"From what you've told me about him last time, it sounds like he's nuts. I would If I were you. Quantum physics isn't something to mess with."

"Ha! You learned that from me! See, If I weren't around you wou-oof!"

Celestia responded to Radius's teasing by firmly laying a pillow across his face, knocking his glasses off. The two had the type of relationship where they were comfortable with joking around as they made each other feel like a couple of lovestruck foals.

"Unless you want another pillow upside your face, I suggest you just shut up and snuggle!"

"Heheh...don't mind if I do. Good night, babe."

"Good night my big brained schmoopie doo."

Author's Notes:

Here it is. My most serious work yet. I have been thinking of this one for quite some time and I really hope it is received well. I've proven that I can write "Everyone" and "Teen" rated stories. Now let's see if I can crank it up to the "Mature" level!
