Secret Scum

Scum

It was just this one last time. It was just him and Silverstream, once again, her feathery hooves wrapping around his body, drawing him into a tight embrace. For once, he was pleased that the Glad to Be a Hippogriff Festival was a weekly occurrence still – it certainly made it easy to know when Sky Beak would be out of the house.

He heard Silverstream let out a little moan. He knew that his ministrations would have the intended effect on her. She did always love it whenever he would run his tongue and beak up and down her torso, disturbing her lovely pink fur ever so slightly. He felt a pang of guilt well up in himself at the thought – he shouldn’t know this about his sister, shouldn’t feel this way about her. Only scum feel this way about their sibling, know such things about them, and act on them.

All he ever wanted was to be normal, was for her to have an easy life, free from the judgmental stares of others. Whether those stares actually existed or were a product of an anxious pubescent mind was of little consequence. What they were doing was wrong – but then, why did it feel so wonderful? Either way, he was determined – this would be the last time. No matter how much it hurt him, he would have to end this at the conclusion of activities, in order to set Silverstream free to pursue a non-scum life. It was probably already too late for him.

He must have been aimlessly licking, while wallowing in his thoughts, because he caught Silverstream shake her head ever so slightly. He silently cursed to himself – could he no longer even do this correctly? “Silv, is something wrong?”

“No, just thinking about stuff,” Silverstream began.

He wondered what she might be thinking about, not missing the irony that he wasn’t the only one lost in thought.

“You’re really good at this, Terra.”

He tried, and mostly succeeded, to suppress a grimace. He could only hope she would interpret it as a grin – he felt that that was the case when he saw her smile. Had he dragged her down to his level, cursed her to spend life as scum just like him? Would she ever find some griff else, so that she could be normal again?

He decided to not waste time thinking about it, and just get on with the inevitable. “Alright, do you want me to get on with things? You’re looking pretty wet down there already.” It always felt so awkward to him to speak so openly to his sister about such things, no matter how many times they did this.

“In a bit – here, let me get that for you,” Silverstream said, as he felt her grip his growing erection in one of her claws, using it to slowly stroke up and down.

He couldn’t help but let out a groan of pleasure – he did always love this treatment from her. He felt his stallionhood begin to swell further and further.

His guilt once again got the better of him, and he began to choke out, “Silv, you don’t have to do that…” repeatedly being interrupted by his moans.

“But I wanted to, Terra.” He couldn’t see her face, but he imagined she was grinning, like she usually did when addressing him with that cutesy, teasing voice. It drove him absolutely mad, and yet he loved it so.

“Ugh, fine.” If this was going to be their last time together, might as well enjoy it all.

The thought of it being their last time couldn’t help but jolt the memory of their first time.

“Hey, mom?”

“Yes, Terramar, dear?” Ocean Flow replied.

“How come Silverstream always gets so quiet and sulky, and spends most of her time locked in her room around this time?” Terramar asked, so innocently.

“Um, well… Have you ever heard of the heat, honey?” Ocean Flow tried to hide the blush that had grown on her cheeks.

Terramar remembered learning about that in the sex ed class earlier in the year. “Yeah, but…” he paused as the sudden realization dawned on him, “You mean that’s what Silverstream has?!”

“Well, yes, she is at the age where that starts happening…”

Terramar straightened his back, now filled with determination. “I’ll go see if I can do anything to help her!” And with that, he swam off towards Silverstream’s room.

“Wait, baby, I don’t think that’s such a good idea!” his mother called out after him, to no avail.

When he arrived outside Silverstream’s room, he made to knock on her door, when suddenly he heard strange noises coming from inside. It was definitely Silverstream, and it sounded an awful lot like moaning.

“Silv, is everything…” was all he could get out before the door opened, ever so slightly. Just like her, he thought, to not fully close her door. He decided to peek inside, to see if something might be the matter. What he saw caused a blush to rise around his head, such that a pufferfish painted in ruby red might be an accurate analogy.

There before him was his sister, furiously plunging her right fin in and out of her vaginal opening, while her left fin worked slightly above, on the clitoris. If he hadn’t been so distracted by the sight in front of him, he might have taken the opportunity to pat himself on the back, for remembering so much from that sex ed class.

And then the scent hit his nose – the almost overpowering musk. Is all this really Silv’s doing? He wondered.

He was about to say… something, anything, when he heard her let out what seemed like a final cry, as liquid seemed to squirt out from her nethers, and the smell became almost overwhelming.

Finally, when she seemed to give a grunt of frustration, he found his voice again. Delicately closing the door so she wouldn’t notice, he spoke, “Silv, you doing okay in there? Is it alright if I come in?”

There was a lengthy pause before he finally heard her respond, “Sure thing, Terra – hold on, lemme get the door.” He noted a slight tone of resignation in her voice, and wondered what that might be about.

What was he thinking back then? What was he expecting would happen? Was the desire always there, to be something more than just a brother to Silverstream, to enter into the world of scum? Or was it something more noble – if something like this could even be noble between siblings?

He decided to place it out of his mind, and instead distract himself by performing one of Silverstream’s favorite acts of foreplay, something he sussed out over the many opportunities to gain such knowledge.

Moving down to her teats, he began flicking his tongue across the nipples, positioning his beak to concurrently scratch up against the fatty mounds underneath. He knew he was doing it right once he smelled her arousal spike, to the point where his nose was completely filled with her scent. He did always love this part – the fantastically firm, fleshy feel of her erect nipples, with the wonderful contrast of the soft areola underneath, and then the electric, earthy taste they imparted.

He soon felt her change her grip, as she began to delicately stroke the underside of his stallionhood with her clawtips. His favorite act of foreplay. It was no wonder when he felt an involuntary shudder momentarily overtake his body.

She knew him so well. He felt a powerful love swell up in his chest. Was that when he first started falling for her, back during that first time?

Seaquestria, 2 years ago

The door opened, and there was Silverstream, still flushed. “So, what did you want to talk about, Terra?”

“Well, I always noticed that you would shut yourself in your room around this time, would always get way quieter than you usually are, so I decided to ask mom about it. She told me about the heat, Silv. Is there anything I can do for you?” She really was beautiful – he mentally kicked himself for thinking such a thing.

He smelled her scent again, seeming to grow stronger… somehow. He felt himself begin to get erect, so he tried to subtly cover himself up, hoping Silverstream would be so distracted by other thoughts that she wouldn’t notice.

“Uh, yeah, could you get me some of mom’s kelp chips and fish oil tea? Those are always my favorites.”

Something in him told him that wasn’t what she actually wanted – part of him wanted to just get out of there anyway, to avoid any situations that might arise. The other part wanted to stay and find out what she really wanted – perhaps it already knew and wanted that itself. “Alright, sure, no problem, sis. Is there anything else you might need?”

She seemed to be debating with herself, as he noticed her eyes flitting back and forth. Finally, she responded, “Actually, there is. Could you please just…” She seemed to be really hesitating to say what she wanted to say. “…just rut me?”

Terramar was certain that shock overtook his features. He could only weakly stammer out, “Wha… bu… no, I couldn’t! What if mom and dad find out?!”

“They won’t – it’ll be our little secret,” Silverstream whispered, in a tone that Terramar found both oddly cute and seductive – he was feeling quite oddly attracted to his sister by this point. “Besides, didn’t you ask what I might need? Please, please, Terra, I need this!”

“Uhm… Shouldn’t you only be doing this with your special seapony? That’s what I remember mom and dad always saying!” At this point, he was saying anything to not just try and get out of this, but avoid having to think about the taboo of such a relation between brother and sister. His member belied his desires, however, as it began to peek out further from his genital slit.

“And who would that be?!” Silverstream nearly shouted, her tone growing more urgent. “C’mon, Terra, do this for me, your favorite sister!”

“Are you sure? Your… your first time… are you sure you want it to be me?” Terramar’s voice was barely above a whisper at this point, heady with desire. As much as he hated to admit it to himself, he did find Silverstream quite attractive, with her lovely pink fur, and soft blue mane. On some level, he must have felt that way for a while.

“You came to check on me when nopony else would. You’re sweet, you’re caring, you’re the best little brother anypony could ask for. Please, I’ve already made up my mind.”

“Well, if you’re sure, then alright, Silv. I trust you completely,” Terramar said, entering the room and closing the door behind him.

The thought of the events after that caused Terramar’s arousal to grow further, as well as shame to well up in his heart. He still blamed himself for taking advantage of his sister while she was in a weakened mental state, for not standing strong and resisting her advances.

“Terra…”

Silverstream speaking his nickname like that woke him from his reverie. He could tell she was just as ready to get on to the main event as he was. “You ready to get on with things?”

“Yes, please, I think it’s time,” she replied, nodding in affirmation.

“Alright.” He proceeded to position himself right outside her entrance, ever so slightly teasing the outer lips, already drenched with her secretions.

He felt her start winking against him, in anticipation. He would miss this part, perhaps, the most of all.

And then, with a single thrust, he entered her, plunging down until his entire length was engulfed by her warm, wet, welcoming marehood.

The tempo of thrusts sped up quickly from there. The room was filled with a cacophony of moans and cries of “oh yes!” and “just like that!”, along with each other’s names scattered in at random.

Terramar’s mind was a complete blank – subconsciously, he was glad to not have to think about the tough thoughts, and just enjoy the moment.

The room was now filled with the pleasurable scent of both their musks. Both their bodies were dripping with sweat.

“Terra, I’m so close!”

He grinned to himself, as he felt the telltale sensation beginning in his balls. “Me too, hng, Silv!” The sensation moved up to his rod.

“Terra, I’m – ANNNGH!” Terramar noticed her eyes roll into the back of her skull, as her orgasm rocked her, squirting all over both of their legs, as well as the bedsheets underneath them.

“Silv, I-!” Before he could say anymore, Terramar felt his essence begin to shoot from his stallionhood, coating Silverstream’s insides as he felt his flare form.

All went silent for a few moments, save for some panting from the both of them.

Once Terramar regained his thoughts, he began to think of telling Silverstream that it was over. He debated between letting her down gently with a little white lie, or telling her how he really felt, giving her the true reason why they shouldn’t be together anymore.

But he decided against it. He decided she might not take it well after such a pleasurable session together.

Who knows, maybe it wasn’t such a bad taboo to break after all. Maybe there could be a next time. Maybe being scum together wasn’t so bad after all.
