Twilight makes a bit of a faux pas during a night of passionate lovemaking with Sunset

Mistakes happen. Twilight Sparkle knows that as well as anyone. What she didn't know was how annoyed one could make their girlfriend by making one bad mistake in bed.

Until tonight.

Her Bad

Sunset Shimmer angrily rolled over, showing Twilight her back. She was, understandably, pissed off, and Twilight felt very bad about it, for a multitude of reasons. She could see in Sunny’s eyes that she was genuinely hurt, which was something Twilight never wanted to see again. Hadn’t she suffered enough? Besides the unfair punishment of the woman she adored, she felt really bad about one thing in particular.

The timing.

“Sunny, I said I was sorry!” whined Twilight. Sunset turned for just long enough for Twilight to fully understand the severity of her glare, then turned back to stare at her lamp.

“This doesn’t qualify for ‘sorry’,” said Sunset. “‘Sorry’ is when you step on someone’s foot at the movie theater. ‘Sorry’ is when you knock over someone’s drink. ‘Sorry’ is when you ask ‘When’s the baby due?’ and it turns out the person is just fat. The only thing that is less worthy of a sorry is first degree murder.”

“Judging by the tone of your voice, there was a reason behind mentioning murder,” said Twilight nervously. “I don’t know what else to say, but I’m sorry! It was an accident, I swear!” Her naked body was beginning to become uncomfortable in the chilly room (Sunset often slept with the window open). This was usually the point in the night when the two former ponies would snuggle up, sharing their warmth, and have a nice talk.

“Sunny, I can't even put into words how sorry I am, and I swear that I’ll make it up to you somehow,“ said Twilight. Sunset just sort of grunted. “Come on, babe, what do you want from me?”

“I want you to have not done it,” said Sunset.

“If I could go back in time without endangering the whole of the multiverse, I would,” promised Twilight. She couldn't even think straight. “Can't we at least finish before you give me the cold shoulder? “

That was mistake number 2 for the evening.

“You did not just ask me that,” snarled Sunset. She sat up and beamed fire through her eyes and into Twilight's soul while she scooped her clothes off the floor and hastily dressed herself.

“I just mean… When I look at you like that, my brain goes a little bit stupid,” amended Twilight. “I can't even properly articulate just how awful I feel.” Sunset seemed to ignore her.

“I swear to God, you did not just ask me if we could finish. There is no way that you have the balls to ask me if we could finish, I must be going crazy!” Sunset rose from her bed and slid into her slippers. “You know what? Maybe I should go out for a walk, and maybe you should be on the other side side the mirror when I get back!”

“Sunny, don't go!” yelped Twilight, grabbing Sunset’s wrist. When Sunset threatened to reassume her demon form, Twilight let her go sheepishly.

“You know, it's not even so much that you did it,” said Sunset. “I would've gotten over it. No,it's more about the fact that you didn't notice! What the hell, Sparky?! Does this just happen to you sometimes?!”

“Yeah.”

“Get out of my house.”

“I'm serious!” swore Twilight. “It hasn't happened in a while, but before we got together… I don't do it intentionally, it just slips out sometimes!”

Sunset knew that Twilight hadn't been trying to hurt her feelings. She knew that Twilight was very much so sorry. She knew that it was unfair of her to hold this little thing against the girl she loved. All of this knowledge did not actually stop Sunset from being angry or embarrassed, but it sat somewhere in the back of her mind.

“Why? I don't want any half assed excuses or anything, cause I know what you're about to say,” said Sunset firmly. “That ‘it’s a substitute for God’ shit isn’t gonna fly. So, tell me why, and remember that the wrong answer means a one-way trip to the couch.”

“It's embarrassing.”

“You do not get to be embarrassed! Do you realize how I feel?!”

“Sunset, baby, please stop shouting—”

“You want embarrassing? How about having sex with your girlfriend just for her to yell out someone else's name?!”

“Babe, the neighbors can hear…” whined Twilight pathetically. Her face bloomed red in embarrassment.

“Our teacher’s name! That lady who took me in, practically adopted me, and treated me as a daughter? Yeah, she's real low on a list of people I wanna be thinking about in the sack!”

You could cook an egg on Twilight's face by that point, and she showed no signs of returning to her normal, purplish hue. When she made the plans to visit Earth and spend the whole week with Sunset, this was not at all what she had in mind.

“You think you're embarrassed? I still talk to her, all the time. I’m the one who has to live with it,” said Twilight sheepishly. “Look, it's a really long story that starts way back when I was thirteen, and I really don't want to go into it.”

“Oh, and you think I want to go into sexy-time thinking about Princess Celestia?”

“It’s really kinda gross, and it involves a lot of things I’ve kept secret for many years,” warned Twilight.

“Don’t care. Spill it,” Sunset commanded. Twilight sighed, unable to disobey an order that direct from a girlfriend that angry.

“Alright. Fine. When I was six—” began Twilight.

“I thought you said the story starts at thirteen,” cut in Sunset.

“I need to preface things a bit,” said Twilight. “Will you let me tell it? Thank you.” She cleared her throat. “When I was six years old, I developed a habit of bathing with Spike, because… Well, that doesn’t matter. The point is that we used to take baths together. As puberty began to take hold… Happy little accidents… began to happen.”

“With Spike?” asked Sunset.

“I’m not proud.”

The air grew slightly denser at that point, and Twilight took advantage of the silence by returning her discarded clothing to her body (no point in having Sunset mad at her and catch a cold). She coughed lightly to clear her throat, then continued.

“Now, I don’t know why, but I was crazy horny as a kid. Like, you would not believe just how hot and bothered I’d get at nothing.” Ironically, this declaration was the least embarrassing part of the story. “And I guess the thing with Spike awakened it, because I felt like I was constantly in heat, 24/7, 365. It wasn’t fun. I started to fantasize about… Well, pretty much everyone. The guards, the teachers, Donut Joe, Shining, Celestia—”

“Wait a second! What?!” demanded Sunset. “Go back!”

“Celestia?”

“Further.”

“Donut Joe?”

“Dammit, Twilight, you know what I meant!” snapped Sunset. “Did you say you used to fantasize about your brother?!”

“I told you, I was super horny. I think there may have been something wrong with me,” admitted Twilight. “In any case, I never did that much about it, kinda just kept him in my thoughts… Whatever, I had super-equine levels of libido and I couldn’t share the bath with Spike anymore. Mistakes would’ve been made, and I might've ended up pregnant. But, I had nothing to keep the tension off, so I got into photography.”

Sunset Shimmer, believe it or not, was with Twilight at first. She understood the whole thing with Spike, and being perpetually ready and raring to go. She even, to a degree, understood the uncomfortably incestial feelings that Twilight was feeling. But when she brought up photography, the Princess had officially gone into uncharted territory.

“I took pictures of ponies… Ahem… Going at it,” said Twilight.

“Oh my god… My little princess was such a pervert! Who would’ve thought that the Princess of Friendship would be a Peeping Tom!” laughed Sunset. That laugh made Twilight feel a little better about the whole situation.

“Anyway, I would get pictures, take them to my room, and… Alleviate stress,” continued Twilight. “I remember I caught this weird one of my parents, where my mom was wearing this police cap and she had a riding crop… This is weird, isn’t it?”

“Oh, yeah.” Sunset laid herself back down on her bed. “Do go on.”

“Right. Well, above everypony else, I had an obsession with Princess Celestia. I mean, why wouldn’t I?” said Twilight. “She’s a goddess. So, one day when she wasn’t looking, I managed to sneak a picture of her flank. Tail up.”

“How in Tartarus did you manage that?”

“Freak luck and waxed floors,” said Twilight with a laugh. “That picture calmed me down considerably, to the point where I only needed to get off three or four times a day. But… One day, I went for five, and the door wasn’t locked…”

“And she walked in on you?” snickered Sunset. Twilight shook her head.

“Shining walked in on me. Followed by my parents. And the superintendent of the school,” sighed Twilight. “And then Celestia. Mind you, all of my pictures were out at the time. All of them.”

Sunset Shimmer was suddenly a bit less angry. What just happened with Twilight was humiliating, and a bit hurtful, nobody was denying that. But that pales in comparison to the ordeal that Twilight had endured when she was just a teenager.

“I still don't see what all that has to do with now,” said Sunset.

“The most intense orgasm I recall ever having occurred whilst masturbating to Princess Celestia,” sighed Twilight. “I was moaning her name throughout, and it just became a reflex whenever I was… Ahem. Getting close.” Twilight felt like she needed a shower after looking back on what a filthy teen she used to be. “I must do it all the time. I don’t know how you’ve never heard it before.”

“Because you’ve never screamed it at the top of your damn lungs!”

“Again, sorry. I’m desperately, unfathomably, insurmountably sorry. Please forgive me,” said Twilight. She grabbed Sunset’s hand in her own, looking at her with an expression that beamed regret and remorse. It was an expression that Sunset herself had become quite used to wearing herself. Sunset sighed, lacing her fingers with Twilight’s and squeezing gently.

“It’s okay, Sparky,” sighed Sunset. “I forgive you. I know you didn’t mean it. I don’t like being mad at you. Plus, you clearly feel bad about things.”

“Very, very bad,” said Twilight.

“Why don’t you show me precisely how bad you feel?” Sunset pulled Twilight nearer, until they were almost touching. “Show me exactly how sorry you are, baby.”

Twilight grinned, then pressed Sunset flat on her back. She shimmied down lower in bed, determined to make her girlfriend properly understand the depths of her remorse.

“Ooh, yes… Keep doing that…”

“Mh-hm…”

“F-fuck, babe, I’m getting close…”

“G-god, I’m gonna… Oh, fuck! Flash! Mmm, that’s so good, baby…”

Twilight stopped, looked up at Sunset, and raised an accusing eyebrow. She wiped her mouth, then sat up to properly glare at her girlfriend. Sunset’s cheeks were tinged red, and she struggled to look Twilight in the eye.

“Seriously?” said Twilight flatly.

“Okay, so, hear me out,” said Sunset.

“I’m listening.”

“We used to fuck, and he did a thing with his tongue just like that.”

“So what? I’m just a fill-in for Flash?” asked Twilight. Sunset rolled her eyes, crossing her arms over her chest.

“Literally fifteen minutes ago, you were moaning our teacher’s name, so I don’t really know if you have room to bitch.”

Twilight opened her mouth to protest, then closed it immediately. She had already messed up enough that night and somehow emerged intact. No point in pushing her luck.

“I’m gonna go back to eating you out now.”

“Good girl.”
