A/N - As an asexual, writing smut is always troublesome. Hopefully, it turned out alright. Don't read if you are uncomfortable with this kind of stuff.
It was the night before the infiltration plan and most of Ishigami village was buzzing with excitement. Of course, since Homura was watching them, all the village had to pretend it was an ordinary night.
So like usual, Gen and Senku were in their room with Chrome below them. Senku was staring into the telescope, studying at the night sky. Gen was tossing and turning in his sleeping bag, too anxious for sleep.
Chrome, well, he was about the only villager in the town who was peacefully sleeping. Lost in his dreams of Ruri and science, he could be considered dead if not for his loud snores.
"Damnit, couldn't he snore quieter?" Gen muttered, sitting up quickly. "Shutting him up is 10 billion percent useless," Senku stated, looking up from his telescope. "He'll just continue to snore the next time he falls asleep."
Gen nodded, slipping out of his sleeping bag and making his way over to the scientist. "Shouldn't you being sleeping?" He asked, making space for the mentalist to sit next to him. "I'm too nervous."
Senku nodded, wrapping an arm around his boyfriend, pulling him closer. "Don't worry, if everything fails I'll fall into hell with you." Gen smiled a bit, nuzzling into Senku's chest.
"That's not normally comforting, but I'll take that."
"Stop complaining mentalist. I don't have a lot of flirting material with me."
"Oh wait, crap, I just remembered something." Gen lifted his head, looking directly into Senku's warm red eyes. Senku arched his eyebrows, waiting for him to finish.
"Chrome's going to fall into hell along with us," Gen whispered. Senku groaned, "Do technicalities count? The whole point was it was supposed to be romantic."
Gen chuckled softly, kissing Senku. "Just teasing you." He leans in again, kissing the scientist again. Senku mutters under his breath but obliges to Gen's kisses.
The kisses between them started as innocent before they got more passionate and deeper. Senku smirked, thrusting his tongue into the mentalist's mouth.
Gen yelped, his cheeks blushing from embarrassment. He could feel Senku's tongue in his mouth, licking all over the place, leaving no place untouched.
A/N - *shudders* I always hate having to write mouth stuff. Anyway, from here on out is the juicy stuff. Enjoy!
The two disconnected for some air, a trail of saliva as proof of their previous action. "Senku-chan~" the two-toned male chirped out, his fingers slowly undoing the scientist's shirt.
"Gen.." the male hitched, grabbing his hands, momentarily stopping him. "How far do you want to go?" he asked, "Because you are aware where this heading."
"Senku-chan, I want to do it with you" Gen responded, meeting the scientist's gaze. Senku nodded, that was all he needed. He grabbed Gen's chin, kissing him harshly.
He gently pushed the mentalist onto the ground, attacking his face as the two undress each other. "Aww, Senku~" the two-toned male moaned as Senku nibbled on his neck.
He let his hands wander around Senku's upper half, touching the scientist's arms, chest, and stomach. "Urgh!" Gen yelped, covering his mouth as he felt pain and pleasure erupt through his body. "Did you just bite me?"
"Got a problem with that?" Senku cockily asked. He grinned, his face flushed and his eyes clouded with lust. "Now people know your mine." Senku squeezed one of Gen's nipples, watching Gen's cute response.
"Senku-chan~" the mentalist purred, tugging gently on the Senku's hair as the scientist played with his nipples. "You look sexy," Senku eventually said, staring lovingly at the male below him.
He smirked, seeing a bulge between mentalist's trousers. "Hmmm, what's this?" He teased, pulling his trousers down, grabbing Gen's manhood. "Senku-chan~" he pouted, feeling Senku's warm mouth touch his dick.
"Agh!" He groaned in pleasure, feeling Senku suck and swirl his tongue. Gen threw his head back, thrusting Senku's mouth to take in all of his manhood. Senku made some choking sounds, bringing Gen back to reality. "Senku-chan!" the mentalist fussed, watching the scientist choke on his cum.
A/N - Fun fact, my step-brother choked on cum before.
"Jesus...trying to kill me, Gen?" Senku joked, catching his breath. "Are you alright?" Gen asked, hugging Senku in assurance. "We don't have to continue if you don't want to."
"Are you kidding me?" Senku looked at Gen incredulously. Gen shuddered, feeling aroused in Senku's sharp gaze. "I-I guess we're continuing then," Gen whispered, feeling Senku put a hand on his hip, pulling him close.
"Where were we?" Senku's husky voice asked, slipping a finger into Gen's hole. Gen purred, feeling Senku enter another finger, scissoring him. "Agh, Senku-chan no fair!" the mentalist pouted, leaning into his neck.
"You've been pleasuring me all this time, but what have I done for you?" He murmured, groping Senku's manhood. He bit down gently, enjoying the sound of Senku's gasp and groan.
"Well, mentalist. Show me your magic." the leek haired man teased, pulling his fingers out of Gen's hole. He whimpered in response, which made Senku chuckle a bit. "Don't worry, you'll get something better instead."
He freed his dick from its confinement and lined up with Gen's hole. "It might hurt a bit." the scientist warned, nuzzling the mentalist's neck as he entered in.
"Ughh, nrggh. It feels so strange Senku-chan~" Gen purred, clinging onto Senku's back. "I'm going to start." Senku hitched, moving his hips ever so slowly but finding it near impossible to stop.
"Urgh!" Senku groaned, going faster and deeper. "Awww, Senku-chan, more!" Gen moaned, feeling Senku's manhood throb in him. So hot and hard, so pleasurable.
"Urrgh, you're squeezing me dry!" the scientist replied, holding onto Gen's legs as he pounded into him. Gen nodded, his back arching with rolled-back eyes in the immense pleasure.
"I-I"m gonna c-cum!" He shouted, feeling the white liquid shoot out onto his stomach. Gen sighed, his body trembling from pleasure as Senku pounded into him, cumming inside him eventually.
Senku pulled out, collapsing next to Gen. The two laid there for a while, Gen falling asleep next to Senku. Senku smiled, cupping his face. Cute, he looks so peaceful sleeping.
He pecked the mentalist's nose before dragging the sleeping bag over to him. He picked him up and got him settled into the covers, joining him as soon as his head hit the pillow.
Love ya, Gen Asagiri
