Chapter Text
The bath had an open roof, while there were still places to shelter from the rain, the sky could be seen, but even if you had climbed a tree outside, no eyes could see into the outdoor bath. The only way to see what was happen in the bath was to be in the bath area. The sound of water falling from the open mouth of a stone statue of a lion head drowned out any sounds that would be coming from outside, and hopefully would dull any noises coming from within the bath.
Senku had seen the bath briefly early, but the building had been full of people working and chatting. This was the first time he was viewing it as it would be from then on, a place of pleasure. His harem had been pulling him along, but when he came to a halt to view the outdoor bath, they let him go. They all understood it wouldn’t be a good night if Senku felt forced. The harem sank into the bath and made pleasant noises as the warm water soaked into their skin. Senku had taken a few seconds to process and began walking to the edge of the hot spring bath.
He sat on the edge and slipped into the bath, feeling the warmth of the water caressing his whole body. Senku thought about how he had never had warm sake in a hot spring before, since he wasn't old enough to drink it before. It would have to wait a bit longer before he could try it, because even though they had reinvented alcohol, they hadn't recreated specifically sake yet. Even if he had been old enough back before everyone turned to stone, he always wished to leave the hot springs quickly, having seen relaxing in the water as a waste of time when he could have been running tests on his latest projects at the time. So this would be the first time he would enjoyed the hot spring and the company of others in it. The heat of the water and the situation he was in left his face red. A hand under the water slowly wrapped around Senku’s fingers, grabbing his attention.
Chrome was looking at Senku, a mix of emotions on his face. While Senku was sure Gen could figure out all the meanings and emotions behind that look, Senku could only understand a few. One was concern, and another was lust. Something else he could read was his desire to ask a question. Senku could guess what it was, but he would rather let Chrome lead this encounter.
“Senku…?”
“Hm…?”
“Can I have sex with you?”
“…sure…”
Senku wished he had something smart to say, something to embarrass Chrome for asking such a thing, but he had nothing. Both he and Chrome had agreed to this harem knowing it would mean sex, this was just a formality. He was asking it before anyone else could, because if he wanted to experience something first hand, he had to be proactive. There was no joke to be found.
Senku didn’t know if everyone else backed off, or if Chrome got closer, but next thing he knew, Chrome was kissing him. It was less forceful that the first kiss, Chrome had probably had time to think over the first kiss and was starting this one more naturally. It was a pleasant kiss, and he almost forgot he was naked with four other naked men, but a hand resting of his hip kept him in the moment. They pulled away, Chrome looking into Senku’s eye for any doubt.
The sound of water splashing caught Senku’s attention and he noticed Ryusui had pulled himself out of the water and was sitting on the edge of the bath, eyes meeting with a smile from the blonde. Senku was pulled back into the kiss and the hand they had been resting on Senku’s hip crept back until it rested on the lowest part of Senku’s back, finger dipping lower into the space between his cheeks.
Chrome pulled back and studied Senku. “I need to open you up so I can fit in with out hurting you, right?” Chrome asked, gently rubbing his anal sphincter, prepared to began opening him up. “…yes, usually we would use lube or saliva, but the water of the hot spring should work for now, as long as you are gentle. I would recommend going slow for your first time. It will make it easier to understand what feels good.” Senku explained, keeping his voice steady as Chrome’s middle finger threatened to slip in. Chrome nodded and kneaded the the skin around Senku’s hole.
Once it had enough give, the tip of the finger slid in. Senku let out a sigh. He had taken Tsukasa’s full size, but his harem had left his hole alone for a few days now, almost a week without penetration had led to even a single finger being worth making noise. The finger pushed in deeper until the the knuckle hit on the edge.
Chrome look at me with wonder, but then looked over my shoulder at Ryusui and nodded. Senku was confused. In the following seconds, Senku was turned around and pushed forward. It was his hands coming up and resting on Ryusui’s knees that stopped his face from drifting into Ryusui’s dick. Senku was now mere inches away from the blond man’s dick while a second finger was added to his ass. Senku moaned in a tiny voice and raised his head just enough to look at Ryusui’s face. The man smiled at him, a blush creeping onto his cheek so slightly, Senku thought he imagined it. “If you are feeling up to it, I’d be happy for this to be my first release with you.” Ryusui played with Senku’s hair, his hand dripping water, the weight of the added water pulling Senku’s hair down until it lay around his head, brushing against his shoulders.
Senku looked at the dick in front of him and let his tongue take a slow lick around the glands. Ryusui hand grips down slightly on Senku’s hair, keeping his face close. Senku experimentally opened his mouth and let Ryusui’s tip sit on his tongue. A startled moan escaped from around the tip in his mouth as Chrome pushed in a third finger. It only lasted a second though, as the fingers were quickly pulled out and something hard pushed against one of Senku’s ass cheeks. Senku looked around to see what Tsukasa and Gen were doing, to see if they were upset or jealous. Tsukasa was sitting on the edge of the hot spring bath on Ryusui’s right, and Gen was on his left.
They both seemed fine, and instead them seemed more concerned if Senku was okay. Tsukasa spoke first. “You ok, Senku?” Gen spoke next. “We were gonna see if you were up to christen the harem’s first session by also give us handjob, but that’s probably too much, huh.” Tsukasa spoke again. “Yeah, if you want to doing something with us later, we can wait.” Senku felt like it was a a nice challenge, and he wanted to see if he can mental handle all four at once.
Senku wiggled his fingers on Ryusui’s knee’s and the blond seemed to get the message. “Chrome, can you hold Senku in place by his hips? I’ll hold his shoulder so he can use his hands.” Ryusui spoke, letting the hand in Senku’s hair drift down until it rested on the sholder, his other hand coming up from where it had been before to hold the other shoulder. Chrome’s hand grabbed both hips, the tip of his dick sliding a little closer to the hole that was stretched open not long ago.
Senku moved both hands, staying in place due to the four hands holding him up. Both hands moved to grip Tsukasa’s and Gen’s hard dicks. Senku’s mouth was starting to hurt a bit from just rest on Ryusui dick, so he pulled off, took a breath, then started bobbing his head. Both his hands moved in tandem, rubbing the shafts of the guys on both sides. Chrome moved and the tip now sat at his hole. Senku moaned as he sucked on Ryusui’s dick, and wiggled his hips in anticipation.
Chrome pushed in, and Senku stopped everything for a second as he felt the slight pain and pleasure of his ass being stretched by Chrome’s length. Senku started back up again and he began to droll on Ryusui. He hadn’t noticed how hard he was until that moment, and he came as Chrome bottomed out inside of him. The whimper that left him made it clear to everyone what happened. Senku squeezed his hands around the shafts and sped up his movements. Chrome started pulling out and right when he reached the tip he pushed back in. It was slower than Senku would usually want, but with two handjobs and a blow job on top of his ass being fucked, if it were faster, he would probably pass out from overstimulation.
Senku felt like his knee’s were giving out, lucky he was in the water and was held up, so when his knee’s bent, he began to float in place. Senku pushed himself until he had taken all of Ryusui’s length into his mouth. He felt his shoulder being squeezed and Ryusui laughed under his breath. “Senku, I’m about to cum. I ask that you either pull off now or get ready.” Senku moaned at the thought and moved as close as he could, his nose pressed into Ryusui’s pubic hair.
Ryusui’s grip was likely to leave a slight bruise. A long deep moan left Ryusui’s lip as Senku felt a burst of heat in his throat. Senku felt his eyes cross and he let the heat slide down his throat, he could barely taste the semen since it almost entirely bypassed his mouth. It wasn’t until Ryusui started pulling out that the salty flavor spread across his mouth. Senku took some deep breathes. His breathing was interrupted by a moan as Chrome managed to find his prostate. “I see, this is where I should aim, Right?” Chrome asked, but he didn’t wait for a reply and continued to hit the spot. Senku felt like his handjobs had gotten sloppy, but he couldn’t focus on fixing them when his prostate was being drilling into constantly.
Senku felt another orgasm about to hit. Since his mouth was now free, he managed to get out a wispy “I’m cumming.” Before he laid his head on Ryusui’s leg and released into the water. Chrome groaned as Senku’s hole tightened down on him. “I can’t go… any longer. Senku, what should I do?” Chrome asked. His finger dug into Senku’s hips, clearly showing he wanted to cum inside, but he was waiting to see if he was allowed to. Senku was still trying to recover from his third orgasm that day, and couldn’t find his voice. He wiggled his hips, pushing back on the cock inside of him, pushing it just a bit deeper. The movement was too much from Chrome to handle. With a breathy noises, his seed shot out and started to fill the space inside of Senku. Chrome was slightly fucking him through the orgasm, clearly wanting to enjoy his first time the most he could. Senku came down from his orgasm high and started putting all his focus the the hand jobs.
Senku rubbed his hand over Gen’s balls, pressing the skin behind them, he pressed into the spot on the perineum that connected to the prostate, Gen moaned suddenly and tried to close his legs, gripping onto the edge of the bath. Senku continued to stimulate it and in no time Gen was cumming on Senku’s wrist. Senku looked over at Tsukasa and saw he was close. Senku played was Tsukasa’s tip and let his pinky press into the opening. Tsukasa hummed, and Senku was trying to think of what else might tip him over the edge as he noticed cum leaking out around his finger. Tsukasa let out a quiet sigh of pleasure as his dick jolted as it continued to ejaculate.
Once he had finished, he looked at Senku and noticed his eyelids were drooping. Sliding into the water, Tsukasa reached for Senku. Senku let himself be grabbed and he was pulled close to Tsukasa. “Are you ok with me drying you off and laying you in bed?” Tsukasa asked, rubbing Senku’s back. “Yeah, that would be nice.” Was the last thing Senku said before he drifted off to sleep.
