Chapter Text
Senku wasn't sure why everything escalated so quickly, when his mind started to basically making up lame excuses to come over to Luna Wright's place almost every day after class, and here they were, after all his internal debate, chilling by the pool where a half-naked Asagiri Gen and Luna's dad, Dr Xeno, were discussing some business like a pair of snobs.
The girl was trying in vain to catch Senku's attention, not even noticing that the boy was practically drooling over her father's business partner. Gay as the fuck, anyone can see that, how could she be so blind?!
If Senku wanted to put his finger on the exact moment he fell for that magician's charms, it would be a week ago, when they first met on this very place, a quiet afternoon when Luna had to pick up a call and left him all by himself, an amazing view to contemplate in the meantime.
God, Senku was so glad he accepted the pink haired classmate's invitation to her place, an obvious but failed attempt to get into his pants. Again. For the hundredth time.
If she knew he was gay as hell. The girl would probably freak out, not that having her noticing was a problem to the young scientist anyways. He never let Luna believe he was interested in her somehow, not his fault.
Asagiri Gen was a "mentalist" like he called himself very often, and a heartless businessman through and through. Everyone wanted to take him to their side for he was cunning and silver tongued, beautiful yet carrying such seductive aura that the bastard knew would put anyone on their knees and a keen, sharp mind, for potentially good deals.
The man was the full package and he was so damn aware of it, always using that fact for his advantage.
Gen's life was like an adventurous and unpredictable Hollywood movie, full of luxury and the proper number of flings. He didn't need anything extra or so he thought, until he laid eyes upon that gravity defying mass of messy hair and the young man who belonged to, Ishigami Senku-chan, huh?
Gen shook himself off of that train of thought, he was no hormonal teenager, he could control himself and stop eyefucking the 19-year-old college student who was apparently eyefucking him in return, damn.
—So, if you take a closer look at this contract then.... —Dr. Xeno was explaining something about the "small letters" and scams, interrupting whatever kinky position he imagined the little scientist in this time, was he even that flexible though?
—Ah yes, sorry Xeno-chan, I was istracted-ay ~ and yes again, even a fool can tell, they tried to scam us, how preposterous! ~ —Gen smiled, resuming to his antics once more, he didn't need Xeno Houston Wingfield of all people to suspect about his sexual interests in his young daughter's classmate, he would find that un-elegant and scandalous or even worse, having his friend thinking he was drooling after his own daughter, that would be so much more errible-tay ~. The bicolor haired man smiled wickedly at the thought.
The other man looked at him for a moment before continuing the conversation. —And that's why you're here Mr. Gen! I know we can take it right back at them, in an elegant way of course!— Gen giggled a little, all of Xeno's antics made him always laugh for they were not only business partners but longtime friends, they knew each other very well and that's why he needed to be cautious about Dear Senku-chan because he'd be damned if he lost his chance to bed that cute college student, who was still looking at him like he was the best thing since sliced bread.
The plan was very simple, he would seduce him without much effort, just a single touch here and there, long stares, body language and lots of skin, he was a mentalist after all and he knew his element. Asagiri Gen was a predator, and Ishigami Senku his prey.
*--------------------------------------------------------------------*
—Senku, are you even listening to me anymore?— The petite pink haired girl noticed he wasn't hearing a word of what she said and started to get annoyed.—I Know you admire my dad's work but you're hangin' out with me, come on!.—She prodded a little childishly, but cutting effectively through the scientist's mind.
Damn, was he staring that much? So hopeless.
—Ah sorry, I just got curious. Where were we? — He tried to amend, listening to Luna's constant rambling and uneasy for he could feel the cat-like eyes watching his every move, he was going to go crazy someday, was even a good idea to keep coming here?
The girl kept rambling until the firsts shades of the sunset appeared and Senku announced he was returning to his dorm, hopefully to forget about his crush on Asagiri Gen, and that was the plan until after a little conversation with Dr. Xeno, the mentalist offered to take him home because "I'm leaving so I can take Senku-chan home way faster and comfortable than the orrible-hay bus~", boy he was in for a ride and he didn't even knew.
Senku was like a pig walking in to the slaughterhouse happy and waiting for a bit of food and the older man wanted to get a bite of him.
Short walking to Gen's car and making small talk and even making snarky remarks to one another like they were old friends was melting Senku's nerves away, until the older of the two started changing his demeanor to something deep and rich, drawling every syllable in the best way; fuck, was he always this effortless for him to be sexy? Apparently so.
So lost in his horny thoughts, Senku didn't notice they stopped at his dorm's entrance; he was feeling like a teenager all over again and hated every bit of it until of course, he looked at Gen.
The street lights made him look straight out of a romance movie, like the charismatic and attractive love interest; The curve of his Cheshire smile and the warm grip he had over Senku's right thigh, Senku wanted to bend him over and.... wait, thigh?
—Ku-chan.... Senku-chan! Are you there? we're here, you look so ired-tay, were you even resting back on Xeno-chan's place? or, looking at me all day tires you out so sooo much you can't even talk? ~ —The young scientist didn't even noticed Gen was gripping his thigh to catch his attention until now, teasing him although it looked like he was taunting him, so close.
—Sorry, that's not it Mentalist ...I was distracted. I must be 10 billion percent done with social interaction; Luna can be a bit draining with all her gossip chit chat haha.... — He tried, very, very hard to make up some excuse and bolt out of there immediately, but Gen exposing him like that and looking pleased with it didn't help with his problem at all.
Oh man, he should've taken the bus.
—No need to lie Senku-chan, I won't tell, after all I was looking at you too... impossible not to, I mean, have you seen your hair? How do you even keep it like that? it's mazing-ay ~! — Gen joked, pressing his free hand to the white and green locks just for a second, so soft.
Senku was fucked, he was an adult! a man of science and logic! he couldn't possibly be having a breakdown over a hand on his thigh and a man who was obviously having fun after discovering he was ogling him for the most part of the afternoon.
—R-Right, so, I need to go, I have class tomorrow, see you around, Gen! — Then, he bolted, embarrassed beyond reason, bee lining for the bathroom and not looking at Chrome, who was worried but decided not to pry. Senku would tell him if something was wrong to the point of needing help; his friend was that kind of person.
Senku locked himself and started stripping, going for the cold shower was the best option to get rid of this unwanted erection instead of acting upon it, thinking about that damn mentalist and his voice… and the pressure of his hand but instead of his thigh...
His dick gave an interest but unfortunate twitch, god, what was he? a prepubescent?
Maybe it wasn't wrong to get it off now, he was sort of pent up and it was normal thing to do, he could do it without thinking and that would be it, right?
Gulping and turning the hot water, Senku made himself comfortable against the wall of the shower, just getting to business and taking the enlarged cock in his hand, unsurprised of how good it felt because he wasn't lying about being pent up, that damn mentalist was a royal tease....
—Fuck I hate you so much, you smug bastard....— He panted, there was no point now, he was going to jerk off thinking about Asagiri Gen and he wondered, would he moan cutely like he always talked or would he use that deep voice he showed earlier to him.
He interrupted himself before a moan of his own filled the place, he didn't need Chrome to know what he was doing so he calmed himself down, resuming the slow pace and closing his eyes.
"How naughty of you Senku-chan, touching yourself at the thought of someone 15 years older than you, is that turning you on so much?"
—Ha... Ha.… fuck y-you...— Senku answered to the imaginary Gen who was constantly teasing him about it, he was really in deep for the mentalist. He imagined how good Gen would look with his pretty lips wrapped around his cock, the lewd sounds he would make just to taunt him further, his lean body wet because of the shower and the mental image of that gorgeous face covered in his come, fuck he was getting closer.
"Senku-chan... come inside my mouth ~ or do you want to do it in my face? I know you want it, you're so aughty-nay ~ "
And that was it, imaginary Gen's voice was all it took for him to spill and barely be able to conceal the moans he was trying oh so desperately to quiet down.
He was royally fucked.
