Chapter Text
‘What is Grace doing, question?’
It all started with that question. Grace going back for Rocky was never going to be something he regretted. Ever.
But then — on the way to Erid, problems that had been the last thing on his mind while on the journey to save his friend arose. Like privacy.
Erid was still several years away. 4 years to be exact. He knew that. Had always known that. The journey there was probably going to be long and hard, but that wasn’t the only thing long and hard right now. Thus, the crux of the problem.
Grace previously non-existent libido had come back in full force now that he was relatively safe and psychologically stable enough. And bored. He was so, so bored. Watching movies and exercising could only get you so far.
So he’d picked a day where he was feeling particularly tense, and gone to the other side of the Hail Mary with the excuse to check something about the Taumoeba farms. He’d thought he’d been sneaky enough. Rocky hadn’t paid him any mind — working with a xenonite battery — just waving his arm dismissively. So he’d gone to the other side of the ship laptop in hand, dropped his pants, opened the tube of lubricant he’d prepared beforehand, turned on the first video he’d found on mute — thanks Ilyukhina for the adult entertainment — and gotten to work. It had been nice at first. It’d been a while after all — several years if you accounted for the time he was asleep. As the girls on screen kissed and fondled each other, Grace masturbated quickly. He didn’t have much time, but as pent up as he was this would be over soon. He brought his other hand behind him, rubbing his ass and probing at his entrance. He hissed, he was going to need much more prep for that.
But before he could reach for the lube a voice jolted him upright.
≪What Grace doing, question?≫ Came the sudden mechanical voice of the ship-installed translator that Rocky used.
“Crap!” Grace cursed as he fell face-first to the floor, limbs flailing wildly. Thankfully he was already kneeling.
≪Grace OK question?≫
Grace sighed in frustration. “Yes, I’m ok pal.” Leave it to him to be the first human to ever get blue-balled by a spider-rock alien. Lucky.
≪So what Grace doing before, question?≫
He groaned, face blushing furiously. He was going to have to explain this entire thing, wasn’t he.
“Rocky, I’m sure we’ve talked about human biology, anatomy and reproduction before.”
≪Grace explain before yes.≫
“And I’m sure I told you that this organ… this entire thing is a private ordeal.”
≪Yes Grace explain, but Rocky still want hear.≫
His shoulders rose to his ears as he let out a pathetic whimper. This was humilliating.
“Rocky buddy, why would you want to see this, you’ll probably find it gross. Besides, this is very, very personal, very private. What about your mate Adrian?”
≪Why ask about Adrian, irrelevant. Eating is also very, very private and Rocky let Grace hear.≫
Damn it, he had a point.
≪Rocky want hear Grace now, statement.≫
Well… Rocky was not wrong. He had let Grace watch him eat. He’d explained his own species reproduction and biology when Grace had asked. He’d even explained how they released waste which was an incredibly personal thing to talk about.
So this was past Grace’s fault, him and his damn curiosity.
“Are you sure, pal?”
≪Affirmative.≫
But like with everything when it comes to Rocky, Grace can’t ever say no.
“You know what? Sure, Rocky can ‘hear’. For science. You probably could see me anyway.”
≪Yes, could. Saw Grace touch human reproduction organ and wanted hear better for science.≫
Grace groaned. “Don’t call it that, just say penis — actually no, don’t call it that either.”
He’s met with Rocky’s chittering laugh at that. His rocky alien friend could be so sassy sometimes.
Grace turns around so that he’s laying on his back. He applies more lube to his hand as the laptop playing the porn video lies forgotten somewhere. If he’s gonna jerk off while giving a lecture he’s gonna do it right.
“To answer your first question, I was masturbating.”
≪New word.≫
“Humans can touch their genitals to feel good. It simulates the act of reproduction or mating as you say.” Grace fists his cock again as he sets a slow pace. He’s so pent up he’s not even gone soft.
“When we masturbate, our brains release beneficial hormones like dopamine and oxytocin which not only make us feel good, but they can improve our mood, stress levels and overall mental health.”
≪If this so good why Grace not do this sooner question?≫
“Well, most humans need to feel relaxed and safe enough to feel arousal —that’s the need to mate— and even more so to masturbate. Hadn’t felt comfortable enough until now I guess.”
≪Rocky understand. Grace no worry, I keep safe.≫
Well, gosh dang it. He was tearing up. Crying and jacking off. In front of an alien. He was such a mess. Rocky’s moniker for him — ‘leaky space blob’ — was accurate.
He kept a steady rhythm as he slowly increased the pace. The little wordless trills Rocky made igniting sparks right under his skin.
≪Grace leaking so much.≫ Rocky let out a lilting hum that Grace had come to understand as amusement.
“Yeah, that’s kind of what human do when we jack off.”
≪New word meaning question?≫
“Same as masturbate, just less formal — not polite.” Although there was nothing polite about what they were doing right now, like at all.
≪Grace voice different now. Is it good change question?≫
“Yes, yes it means… ugh, it means I’m feeling good,” Grace explained stiffly. He might explode from pure mortification if this kept on for long. He doubled the speed of is hand. “God, this is so embarrassing.”
≪Embarrassing… Why, question?≫
“Yeah buddy, humans get embarrassed when we have sex — mate, or when we masturbate. Told you this was very private, mating for humans is intimate — normally reserved only for one’s mate or partner.”
≪Humans are weird,≫ complained Rocky, swaying slightly where he stood. ≪Eridian mating also intimate but not embarrassing hear or speak with friend. Share with mates and collective.≫
Huh, that was interesting. Although Grace supposed that made sense since their species have a precise built-in sonar system. He doubted there was any possibility for privacy in that planet.
≪Grace also no worry, Rocky Grace partner, Rocky keep safe, keep happy, always stay.≫
Uh, what? Had the Eridian translator he’d installed into the ship’s computer glitched? He couldn’t have possibly heard what he thought he did. Maybe he had just misunderstood. Yeah, Grace was probably just missing some context clues here. He was sure Rocky couldn’t have meant ‘partner’ in the way he’d automatically understood it.
Too bad his stupid penis hadn’t gotten the memo.
Grace moaned loudly as Rocky’s words went straight to his dick. He unconsciously squeezed it, preventing him from coming prematurely. Big mistake, he could have ended his misery early that way.
Rocky seemed thrilled at the sound at least. ≪Grace feel so good he sing,≫ he chattered as Grace panted. ≪Rocky words make Grace feel good, statement.≫
Well, he wasn’t wrong. Even if Grace wanted to die from shame.
“Y-yeah, what you said was… nice. I liked it,” He admitted. It’s not like he could lose even more dignity than he already had.
≪Eridians also talk during ♪♫♪♪ thrum, it help partners feel good. Rocky talk more, request≫
Grace just nodded as he resumed his hand’s movements, incapable of answering… any of that.
≪Happy happy happy. Grace must feel happy, feel good, feel relaxed,≫ he continued, making jazz-hands at Grace’s moan of pleasure. ≪Rocky help Grace, keep safe, keep happy. Grace sound beautiful, Grace happy good, good, good.≫
Suddenly there was a slight buzzing that vibrated through Grace’s entire body, from the top of his skull to his toes, making him whine and raise his hips in shock.
“W-wha– ”
≪Grace feel that, question?≫ Rocky sounded extremely proud of themselves at that. ≪Yes, good good good. Grace feel ♪♫♩ inside. Rocky voice make ♫♬ and feel good, no think just sing.≫
So even if he couldn’t hear it, whatever weird alien thing Rocky was doing to him with his voice could still be felt. God his life was so awesome. And strange. Mainly awesome though. This also worked for him sexually too — his dick was throbbing something fierce, ‘cause apparently, he was a freak.
Grace quickly beat his cock, all the while Rocky purred his infrasound encouragements intercepted by random ‘Good’, ‘More sing’, and ‘Grace sound pretty’ calls that were driving him crazy. But it wasn’t enough. He was right there but he could not cross the line. He needed more.
With a groan, he lifted his leg and reached behind him with his free hand. Grace caressed his testicles, then his perineum, then he finally pressed on his entrance, making his legs jerk.
≪What Grace doing now, question?≫
“This… human rectums are also very sensitive even if they’re not part of the reproductive system,” Grace described as he pressed into his hole. “Especially for human males. It feels good to touch inside, to ahh… to insert fingers, genitals or objects.” With a gasp, he finally breached inside.
≪Rocky can hear. It similar to ♩♩♪♫ with eridians. Great, encourage Grace keep singing.≫
Didn’t have to tell him twice. His moans kept escalating as the pleasure climbed and climbed. He’s vibrating, he’s twitching, he’s roughly fingering himself and then he’s there, he’s there he’s–
With a shout Grace comes all over himself, his whole body twitching in the aftershocks. Holy crap, he thinks that’s the hardest he’s ever climaxed in his life. With a mewl he removes his finger, hands falling to his sides. He turns his head to look at Rocky. If he didn’t know better, he’d think he was… almost disappointed. His carapace is hanging low, four limbs drooping by his side.
≪Grace leaked, is over, question?≫
“Yeah Rocky, I’m all done,” Grace sighed, covertly wiping his hands on his shirt. Yup, his alien friend was disappointed this was over. Rocky had let out a long, sad warble at his response. Well, excuse him if he couldn’t last long, okay? He had been very pent up.
≪Grace finish very fast. Much faster than ♪♫♪♪ thrum.≫
“That’s a very rude thing to say to humans pal,” Grace snorted.
≪Rocky just say fact, statement,≫ he complained. ≪Not rude, Grace just too fast, fast, fast.≫
“Ok, ok, I get it! I’m sorry for being such a quick shot, alright?”
≪Yes Grace very quick, not enough Rocky need hear again.≫
“Woah!” Grace hastily sat up. “Easy there tiger, I can’t handle doing all that again so soon after finishing!”
≪Rocky no tiger no earth animal, Rocky is Rocky. And why not question?≫
“I simply can’t. It’s called a refractory period. Human males especially, we need to rest after climax or it will hurt. Although some people — like me — do like the overstimulation–”
≪Grace like stimulation so sing again, request!≫ Oops. Shouldn’t have mentioned that final part.
“No Rocky, I really don’t feel like masturbating again,” Grace groans, ignoring the alien’s despondent trill. He pulls up his pants, stands up and heads towards the bathroom, intending to clean himself and do some laundry. His clothes are already becoming a sticky mess, ew.
Rocky follows closely behind on his xenonite hamster-ball, insisting on accompanying him into his ‘shower’ — it’s really just some wet wipes — and through his laundry routine. He seems fascinated by the human body now. Grace hoped this wouldn’t become a problem.
≪Rocky want hear Grace body, more voice more sing. When can Grace ♫♬again, question?≫
Grace rubbed his face with his hands as he watched the washing cycle spin. This was totally going to become a problem.
“I really don’t feel aroused at all anymore Rocky, sorry,” he confessed sincerely. “But… if I do I will tell you immediately, okay?” God, he hoped he wouldn’t regret this later.
≪Of course thank, thank, thank. Rocky wait patiently, Rocky will hear Grace sing again!”≫ Well, at least he was happy, making agitated jazz hands at him.
“Sure buddy, whatever you want.” Grace felt lighter than he had in weeks. He was so relaxed he could almost ignore the intense guilt he felt at having gotten off to his mated friend.
