He knew he shouldn’t… he knew it was wrong. But he was still struggling —
One of his students had taken a particular liking to him, and they were very pleasant to talk to. They were happy, upbeat, energetic, and Grace genuinely enjoyed spending time with them. He had given them the name ‘Penelope’, and they were a beautiful purple Amethyst and Quartz Eridian. They had carvings all over their body, and Grace couldn’t help but acknowledge that by at least his standards, she was very pretty to look at.
Well… he now had them in his home, and they were on top of him. They had come over to study, since they were falling behind in their class and he wanted to help them. He never once imagined it would be ending up like this…
He couldn’t even call out to Rocky, because Rocky was asleep with Adrian at their nest— something he did occasionally on the direction of his therapist. To give them some space…
Well, right now Grace was wishing more than anything that Rocky was here to chase Penelope off of him.
“You’re very pretty…” they sung quietly, reaching a hand up to pinch at Grace’s cheek.
“So soft… so squishy…!”
They giggled quietly and shifted themselves, their other hands reaching down and beginning to feel around his thighs. Their hands were dangerously close to somewhere they shouldn’t be…
Even through the thin xenonite suit every Eridian who entered wore, he could feel the heat radiating off of them.
“Tell me about human reproduction, Teacher Grace”
They sung softly, tugging at the hem of his pants.
Grace’s mind went a little blank, and he began rattling off information in hopes of stalling.
“W-well— um.. the male gets an erection, and then inserts his penis into the female… after some time and movement, he ejaculates and— it’s kind of done?”
He was nervous in his explanation.
Penelope unbuttoned his pants and pulled them down slightly, groping him through his boxers.
“Is this the penis, question?”
They asked sweetly, their voice inquisitive.
“Y-yes…” Grace choked out as his hips involuntarily thrusted up into their hands.
“Ah… we really shouldn’t be doing this Penelope, I’m your teacher and— you’re not old enough” he said quietly, trying to gently push them off of him.
They didn’t budge. They were still much, much stronger than Grace, and began to fish his cock out of his boxers, lazily stroking it as their body began to vibrate and send shivers through Grace’s body.
His breath shuddered as he thrusted up into the warm hands enveloping him.
“S-stop— this isn’t —“ he stuttered out, his voice wavering as Penelope seemed to get excited.
“What a pretty sound you’re making, teacher! Please, make more sounds for me”
They squeezed his cock and shifted themselves so their bottom face with their seam was facing his cock.
Grace began to panic and tried a second time to push them off of him
“Hey hey— this really isn’t right!” The fear rose in his voice as he attempted to wiggle away.
“No no, don’t run! I promise it’s okay— I am old! And I like you, a lot. Please… teach me how to feel pleasure…”
Their seam opened, revealing soft sticky flesh inside.
Grace felt something inside him snap. He held onto their carapace and drove his cock directly into their hole, groaning and shivering as his cock throbbed inside them.
It was a slightly different experience than with Rocky, the hole was tighter and the Eridian on top of him shivered and shrieked differently, their warbling tone echoing through the house as Grace ruthlessly thrusted into them. He couldn’t believe he was doing this— cheating on his mates! What would Adrian and Rocky think when they discover he not only cheated on them, but with a student! One of the younger ones, no less!
He groans as he feels them suction around his cock, their ovipositor inside coiling around him and beginning to stroke him slowly.
“F-friiiick— Penelope— you gotta slow down!” He begged
Penelope showed little mercy, and continued slamming down onto his cock in quick bursts.
“It feels— so good…!!” They warbled out
“Thank you, Teacher Grace, for teaching me this lesson!”
Grace groaned and closed his eyes.
He was fucking a student.
A YOUNG student.
And he was feeling good…
He was enjoying himself.
It felt forced at first, but at this point he doesn’t know if he’d be able to stop even if she was willing to.
He HAD to cum inside the tight hole enveloping him; it felt like his base instincts had taken over. This really WAS teaching about human mating— humans can be so thoughtless when they feel good.
He moaned out Penelope's name and she buzzed with excitement, sending shockwaves of pleasure through Grace.
He opened one eye and peered at the beautiful purple Eridian ontop of him. Their marvelous purples leading to whites, the gold engravings they had adorned themselves with.
He felt himself waver.
He felt so much guilt welling up inside of him— and yet his cock still throbbed inside of her.
“I-I’m so close—“ Grace stuttered out.
“So close to what??” They replied.
“To— to cumming! I’ll be filling you up with my semen— in humans it would impregnate you” he knew there was a Xenonite barrier acting as a pseudo condom but the idea of knocking her up had his head foggy.
“Please!! Yes!! Fill me please Teacher Grace, I am very fertile!!” They begged as they continued to grind themselves down and onto him, meeting his hips that he was enthusiastically thrusting up.
“Fuuuuck— I’m— Penelope, I’m cumming!”
He gave one last hard thrust into them as he came, the slick liquid covering his cock as he held himself deep inside of them for a long moment.
His breathing was heavy, and he laid back onto the floor, groaning and feeling Penelope pulse around him.
“Ohh my god that was… amazing…” he muttered.
He was so desperate for physical contact, especially when Rocky wasn’t around… he felt guilt begin to eat at him again. Penelope pulled themselves off of him and plopped onto the ground beside him.
“Amaaaaaziiiiing” they chimed.
Grace looked at Penelope and felt dread build up.
“Now— now Penelope… no one… can know about this little event, okay? Nobody at all— not even your parents”
He felt absolutely awful telling her to tell nobody— but he definitely didn’t want it to get out that he was some kind of… pebblephile…
He began to clean himself up, anxiety spiking the more reality set in that this did in fact, happen.
[They’re like 150 years old— surely they’re old enough] he told himself. I mean sure, compared to a human they were old— but for an Eridian… well. Let’s just say this was definitely not one of Ryland Grace’s finest moments.
He got himself to his feet and began to fully clean up the room, hiding any and all sign of wrongdoing. He looked to Penelope who’s seam was closing, and they got themselves back up.
“Thank you, Teacher Grace… I really liked our session— can we do this again?” They asked.
Grace immediately panicked.
“Uhh— well— I… let me think about it!” He finally blurted out.
“Okayyy~ anything else teach before Penelope go home?” They asked
Grace felt stun locked they wanted to just… continue the lesson? This felt so surreal. He decided, sure. Why not. And he picked a topic for them to study.
Penelope studied surprisingly well after being ‘taught’ by their teacher. After an hour, Grace sent them home. And he just prayed… prayed this was all a bad dream and he didn’t just victimize a young Eridian. Prayed that Rocky would never find out, and pray that this is all a bad dream.
Sadly, he woke up the next day and nothing changed. He immediately felt sick to his stomach when he awoke and thought about the night before. He hoisted himself up and made his way to his kitchen, and began to make breakfast. As he ate he stared out the window, dissociating … head empty …. Until suddenly there’s a loud KNOCK at the door. It makes Grace jump, and he gets up to open it, surprised to see Rocky standing there.
“Grace hello yes hi Rocky awake now! Come visit, how you been question??”
Grace felt his stomach churn immediately.
“Umm… I’ve been fine, good! Everything normal” he hated lying to Rocky but there was NO way he would be able to reasonably tell him this.
“Good good!! Rocky miss Grace! What do today question?? We watch movies or sit outside??”
Grace hesitated for a moment before deciding “movies… I have some ideas”
He set up in his bedroom, cozy on his bed. Rocky curled up next to him as the laptop sat between them. He put on The Loft, Fatal Attraction, and Chloe. They spent the next three hours watching movies about infidelity as Grace mulled over if he should tell, and how he should tell.
“Grace heart rate elevated, Statement” Rocky observed.
“Astute observation– yea it's just um. Normal, it happens when humans watch movies that make them feel things” He explained
Rocky let out a low hum.
“I see… Understood!” He then returned to watching the movie.
Hours passed.
“Why human drawn to other human, question?” Rocky asked.
Grace thought for a moment.
“Well, sometimes… doing something you know is wrong, feels.. Good. And sometimes people just fall in love with somebody else.” He thought about the moment he had with Penelope. She was so much stronger than him, he really felt like he was coerced and forced into it, which made him feel disgusted and violated. But he also hates that it felt GOOD. He loved how tight they were, the sound of their wailing, their beautiful colours. His stomach twisted with the thought he may genuinely be attracted to a child.
‘God, please, anything but that’ he thought to himself
He did his best to remain calm throughout the night,
Chatting with Rocky and spending their day lounging around. When it came time to sleep, Grace settled onto his bed and took a deep breath, relaxing as Rocky settled down next to him.
“Rocky… Could you ever hate me?” He asked, quietly.
Rocky tilted thoughtfully, before responding.
“No. I don’t think so. Anything Grace do, Rocky understands. Rocky help.”
Grace frowned. He wanted to believe him, desperately, but he felt that surely this was too much!
“Rocky… what would you do if I… slept with somebody else?” He asked. “Like in the movies”
Rocky thought again.
“Would forgive. But be sad… why, did Grace sleep with different Eridian?…Who? Grace can admit to Rocky, Rocky will understand” his tone was sad, but understanding.
Grace buried his face in his hands and felt the dam break.
“It was Penelope… and— I — I know how it looks!! I know, she’s so young! And one of my students! She was on top of me, and she’s so heavy I couldn’t push her off, and she was SO pushy! I— I don’t know what to do! I feel like I could be sick, I’m — I am so .. so sorry, Rocky. I never wanted to hurt you like this— please, PLEASE forgive me!” He begged.
Rocky gave a low warble.
“Grace… mate with… a pebble?” The realization dawned on him. How could he possibly handle something of this magnitude??
“Grace… Rocky still love you. But Grace cannot do that again. Rocky will make sure Penelope does not visit Grace again, so Grace is not pressured and tempted. Rocky will talk to Penelope parents, so they can get help they need. Rocky will fix, Rocky fixes things”
Rocky felt absolute turmoil in him. He HAD to fix this, he was the guy who fixes stuff!
Grace felt relief wash over him.
“You— you still love me? I thought of you when it happened — I didn’t want to! I love you so much, Rocky… you and Adrian are my only mates I will ever love!”
He gently wrapped his arms around Rocky and pressed kisses to his xenonite suit.
“Please don’t tell Adrian, I don’t want them to think lesser of me… I just want this to all go away. I feel so disgusting” he buried his face against Rocky and felt tears well up.
“I’m so sorry Rocky… I have never felt so bad in my life…!”
Rocky gently pet Grace’s back.
“Shh shh.. is okay, Grace. Calm, calm.”
He did his best to comfort his mate.
Grace finally felt like he could relax. He was completely drained… he closed his eyes, and slowly drifted off.
As Grace began snoring, Rocky considered the deep weight of what happened and how he’d explain it to people.
It’s okay. Rocky fixes things.
