Chapter Text
Grace half fish!?
Today Grace feel like swimming not only because he wanted too, but also because Rocky tell him that the Eridian “Earth sciences” team has changes the water into a better temperature for Grace. And he think today is hotter then usual so it a good day to having a swim.
knock knock knock*
Grace grab his towel and walking to the door.
[ why Grace lock door again, question? ]
thats the first thing Rocky said to him when he open the door and see his rock friend standing outside waiting for him.
“ Because privacy ”
[ Rocky can see through wall, no privacy with close door ]
oh wow how can he forgot that, he know that Eridian can see through wall but closing the door just give him the sense of comfort so he gonna keep having his door closed.
[ open door better. Rocky can come in anytime, good good good ]
” no rock, you cannot just come in my house without asking ” he said and sigh before closing the door behind him when he walked out of the house.
[ why need asking, question? Grace house is also Rocky house ]
“ what? No it not. It my house, I’m the one eating here and sleeping here ” They arguing while walking.
[ Rocky also sleeping here, Grace like when Rocky sleep here. when Grace and Rocky having sex Grace always begging for Rocky to stay ]
Grace can feel his body temperature rising, his cheek is getting hot and if he can sees himself from second-person perspective his face is definitely red like a tomatoes. Good news Rocky cant see colour, bad news Rocky can sense his body temperature.
[ why Grace temperature rise, question? ] they both stop at the rock beach, Grace can hear the waves when the wind blows, it loud but it not louder then his own heart-beat right at this moment.
“ n-nothing, well it because it summer. That why we here to swim right? ” Grace say awkwardly look at Rocky for any respond.
Rocky doesn't have eyes that Grace could see but he can sense that Rocky is staring at him and that makes his body temperature just getting higher.
[ Grace swim Rocky no swim, statement ]
Grace just nodded but he wanted to tease Rocky so he throw his towel at Rocky and it land on his head, before Rocky could say anything Grace run down the water. When his feet touches the water he can feel the different between the old water and the new one immediately. the old one is definitely much more warmer then the new one, this new water is probably a few Fahrenheit colder then a normal human body temperature.
He in his own little world for a while before he snap back when he hear his Rock friend voice.
[ Grace like the temperature, question? ]
He look back at Rocky before nodding. The water cooling down his body temperature it feels really nice on his hot skin. Small waves hitting his stomach sending vibrations through his whole body, he can’t really explain why it felt just like when he heard Rocky voice for the first time.
[ Grace? ]
” y- yes? what’s ups buddy ” he say looking up from the water to look at Rocky who standing on the dry side.
[ Grace want the science team to add anything else, question? ]
” no no, this is already too much. You guys making this whole space for just for me to live in ”
[ No, not enough, statement. Grace is a saviour, Grace help Rocky, Grace help eridian, Grace safe Erid ] Rocky say while stomping his limp onto the ground making it look like he’s trying to makes his statement clear.
[ Rocky want Grace to be comfortable, statement ]
” I am comfortable ”
[ more comfortable ]
He dont remember for how long he was swimming but if he continue, he think he might caught cold.
His feet finally step out of the water, he grab the towel that Rocky hand it to him and drying himself. He shiver slightly from the wind that makes a contact with his skin.
” I really like the temperature, tell the science team that they dont need to fix anything now ” he say while his hands moving the towel to drying his hair.
[ Grace sure, question? ]
” Yes I'm sure ”
[ Grace dont want anything else, question? ]
” yeah, it okay Rocky I'm comfortable living here ” he said that to Rocky with a slightly softer tone.
[ Okay, if Grace said so. But if need anything tell Rocky ] he say that before stomping one time with his limp.
” yes i will tell you, you'll be the first to know, i promise ”
[ Good good good, tell Rocky everything good ]
-
Rocky already leaving two hours ago, but he feel extra tired today he usually dont get tired at this time of the day but he figured it only because he had swim today so he use up a lot of energy and that why he are tired. He really dont have anything to do, he already go through all the things his Eridian student makes. So he think it would be a good idea for him to just go rest a little earlier for today since he starting to get a little headache now. Hopefully he wont wake up having a cold.
” Okay, good-night Armando see you tomorrow morning alright? ”
( Good night Dr.Grace )
He turn off the last light from his headlamp before buried himself under the blanket.
-
” Holy shittttt! ” Grace dont usually swear but what he woke up to makes it hard to avoid saying the word.
Grace waking up to see his lower body turn into a fish tail, he is really shock and in disbelief. He’s not even sure if he is really awake or if he still in his sweet-dream.
He started to move. The tail felt heavy, it hard to lift it up. His finger brushing over the scale of his tail, the colour is beautiful blue-ish green almost like turquoise but darker and slightly look more blue.
Grace trying get out of his bed but he end up falling down good thing ut didn’t hurt much. He start crawling, it really hard to crawl with this tail, It heavy and hard to move/control, but maybe it because he didn’t get used to yet.
Then he heard the knock on the door.
knock knock knock*
” Coming! ”
He crawl slowly to the door but the handle on the door is higher than he could reach, he trying stretching himself but it almost felt like it impossible to reach.
[ is Grace okay, question. Why Grace lower body look like that, question? ]
He almost forgot that again that Rocky could se through things. but he really need to open this door so Rocky can help him, he is not sure himself how Rocky would help him but he really wanted to see him right now and they can find the solution together.
[ Grace move away from door, statement. Rocky fix ]
He not sure what Rocky means by “fix” but he crawling away from the door giving some distant.
bang’ bang’ bang’
One more loud “bang” before the door broke open.
[ Grace okay, question?] Rocky walking to Grace to check him if he was alright, his craw moving on Grace body checking if he got hurt or got any bruise.
” yeah I'm okay, but i dont know what happened. I just woke up and I'm already a merman ”
[ What a merman, question? ] Oh yeah of course how would an Eridian know about the whole mermaid/merman thing.
” it what i am right now. I mean I am still a human but now I'm half fish half human ”
[ What fish, question? ]
” it a creature on earth that live in a water and have a tail with scale and very leaky even outside of the water ”
[ there many merman on earth, question? ]
” NO! it none ”
[ then why Grace like this, question ] I dont even know the answer myself Rock. I always thought a mermaid was some kind of fairy-tail kid story but now that i am one i think there might actually be a real mermaid on earth somewhere.
” I dont know, i woke up and I’m like this ” they both didn’t say anything for a moment.
Rocky start checking Grace body again, this time not to see if he was injured but to checking Grace new body. his craw moving gently on Grace green tail, Rocky warm finger moving up to touch at the new thing on Grace body, his finger going inside the new body part making Grace jump of the feeling and he got a goosebumps.
” that is the fish gills ” He breathe getting more heavy, when Rocky finger slipped under his scale he let out a soft whimper. It bring a sharp pain to him but it bearable. His body heat rise and he feels like he leaking from somewhere unfamiliar he feels wet and disgusting like Rocky said.
[ Grace leaky. Grace hole leaking, statement ] Rocky say that before Grace let out a sharp high-pitch whine, when he look down he see Rocky’s finger going inside where the unfamiliar leaking liquid are coming from.
“ ah- Rock, mhmm ” Grace can only let out a small noise of pleasure, he cant really form any words in his head right now not that he would want to form any though whatsoever right now.
[ merman so wet, so leaky and warm. Grace likes Rocky touch, question?] Rocky asked while staring at the Merman that laying on the floor even though Rocky dont have an eyes.
Grace can feel the stare from the rock that standing above him while that rock looking hand finger slowly pushing in and out of his hole? He can also see Rocky hole, he see that it start to leaking a bit like him right now. He always wonder how Eridian reproduction works. Rocky shown him a few times so Grace can fully say he understands it now.
Rocky hard rock skin starting to move from each other open the crack that Rocky leaking liquid are dripping from. The skin inside is softer it look squishy then the squishy flesh starting to grown out of his body it starting to form a long, pretty thick flesh that look like humans cock but not fully alike. It look the same from the base to the tip. He can say that it look like when you finish sewing for exempel a leg for your fox plush and you need to push it inside out so it show the side where it not many string.
[ Grace like what he see, question? ] Rocky voice make Grace focus shift from look up at Rocky sex organ to Rocky rock face.
[ Grace is tight, more tight. more more more ] He can’t help that his stupid hole clench tighter around Rocky’s finger. But he can’t deny the pleasure that it gives him, suddenly it feels like it his first time orgasming. The Orgasm hit him hard, like a rock blasted from a volcano.
His mind is brighter then the brightest star in the universe.
[ Grace okay, question? ]
Grace mind slowly coming back to it normal functional-self. “ yes, I’m okay buddy ”
[ Good good good, Grace ready for round two, question? ] Rocky pull out his finger from Grace leaking hole, his liquid connecting Rocky finger and his hole that clenching the air, it break eventually.
Round two?!!! Gosh he can’t even get over the last one but he just nodded. Good thing Rocky is really kind to his now not human body. Rocky begin lifting Grace body, that has more weight to him because of the tail but he still do it so effortlessly. Rocky slowly walking with his three other limps to theirs bedroom, there’s where all the soft material for his Grace weak, sensitive skin could be comfortable laying on and clinging to. Even though he knows Grace prefer to hug Rocky more.
[ Grace is comfortable, question? ] he laying him down softly on the bed before he climbs up beside him.
” yes, i am comfortable. thanks you Rock ” his Rock is the best.
He couldn’t remember how many times he see the brightest star but he do remember every times that soft flesh pushing inside of him, Rocky is so soft even though he is a rock, he’s always making sure Grace don’t hurt or is uncomfortable.
He can’t help but liking this new body, he cant really explain why it makes his nervous system more sensitive. It feel like he could break anytime but he know Rocky would be here making sure he won’t breaks into millions of atom. Grace also like this hole he totally forgot about his little cock each time Rocky pushing in and out his little weak cock twitching pathetically like it could blow out white liquid anytime.
Grace always love the warmness that’s coming from Rocky skin when they are so close. He glad that he be able to touch Rocky, he not sure how the Eridian science be able to makes Rocky breathe and not dying in Grace atmosphere but he cant really think of it now, now he just want to be as close to Rocky as possible.
they always love to makes loves more then fucking but it change up for spice sometimes. It usually Rocky who suggests it, thanks to the smart computer that full of reference.
After the exhausting and pleasure night now in the morning Grace get to take a bath, but with Rocky help!
Rocky hands slowly and softly brushing Grace scale, from his tail up to his hip and then his nipple and face. He will always love to tease his Grace a bit, like seeing him squirm. If he was a human he could see Grace face turning red. All the blood rushing to the surface of his skin and his heart-rate increase makes his breathing too quicken.
He would love to see Grace colour one day.
