TsukaSen NSFW Headcanons
TsukaSen was my very first ship when I started reading D.Stone, they have an amazing dynamic and I can’t wait to see their interactions in the future chapters!! I’m so hyped for Tsukasa’s comeback so it’s headcanon time bitches!!
Warning: NSFW content! These HCs are just my imaginations, If you don’t like this ship, please keep scrolling. But if you like TsukaSen read them ~ Anyway, sorry for the grammar mistakes, my Tsukasen shipper heart blinds me as fuck.
Tsukasa is a loving and caring man who adores Senku’s intelligence. He is always protective and gentle with his smol scientist.
He is Senku’s “bodyguard” and follows him all day long. Sometimes he gets clingy but honestly, he just needs Senku more than anything.
Senku usually acts cocky around him, especially when Tsukasa is too clingy.
Actually, he is a little tsundere and at the end of the day, he just gives Tsukasa one of his charming smiles.
Tsukasa loves to express his affection with gentle hugs and kisses.
Senku secretly appreciates when Tsukasa spontaneously hugs him from behind and wraps his huge and strong arms around him, except when he is busy or needs to concentrate on his experiments.
He hates it when Tsukasa disturbs him in the middle of an important project, but he feels as his whole body is getting hotter because of his touch.
Senku can’t hide his excitement when Tsukasa whispers praising words in his ears. His gentle and erotic voice makes him melt.
But he immediately realizes Tsukasa’s true intention when he feels butterfly kisses on his neck and Tsukasa’s hand touches his skin under the clothes.
It’s very obvious that he wants to have sex with him.
“..Stop it….or do it quickly….”
Senku prefers quickies when he is in the mood, but Tsukasa feels awkward because he doesn’t understand the meaning of “quickies”.
“What do you mean?”
Good sex takes a long time. When he makes love he wanna do it as slow as he can.
Senku is a busy scientist and he doesn’t have time for this, especially during the day.
So he will be mad at him, as expected.
“I mean you should hold back yourself…I’m in the middle of the work…”
Tsukasa becomes a bit stoic when Senku rejects his affection, he will ignore Senku and pretend to have selective hearing.
His behavior irritates Senku as hell.
Tsukasa will learn that the best time for intimacy is the late night after Senku finished his daily work (and his brain stopped thinking about science).
Then Senku loving hours will start.
Tsukasa is an extremely sensual and passionate lover.
His passion is simply too much for Senku, he can’t handle his sensual kisses and touches.
Tsukasa’s loving behavior makes Senku completely submissive, he can’t say no to him.
They stare into each other’s eyes and keep eye contact for long minutes, while Tsukasa gently caresses Senku’s soft skin under the clothes.
Then they will start kissing, gently and sensually until they can barely breathe.
Tsukasa prefers long and satisfying foreplay, he thinks this is the most important part of the sexual act.
When Tsukasa’s huge and strong hands caress Senku’s slim body, Senku realizes that he has no chance to escape Tsukasa’s claws.
Senku is freaking out, especially after he realizes that Tsukasa’s dominance and beast-like strength actually turns him on.
Tsukasa always goes slowly, he carefully licks, bites, and sucks Senku’s most sensitive body parts.
Senku feels like Tsukasa would eat him alive, but he holds back himself.
Senku’s most sensitive spots are his armpits, his inner thighs and (surprisingly) his testicles, Tsukasa loves licking and sucking them carefully.
Besides he loves grabbing and sucking Senku’s butt, sometimes leaves love bites on him.
Senku completely loses his mind during the foreplay because of Tsukasa’s sensual and slow movements.
Tsukasa literally can spend hours worshiping Senku’s body.
Senku’s member visibly pulsates because of his teasing touches.
When Tsukasa finally touches Senku’s hardness, he needs only a few movements to cumming.
Senku never experienced such an intense orgasm before, his whole body is shaking and he can’t speak for a while because of the ecstasy.
Tsukasa finds it the most adorable thing in the world.
He will smile and give loving kisses on Senku’s forehead.
Tsukasa always stops right after the foreplay, as long as he gets Senku’s permission to continue.
It will take time before they are ready for their first time together.
Tsukasa proves to him that he would never do anything that Senku doesn’t want to do.
During the sexual act, Tsukasa is even more sensual than before.
He loves super-slow and intimate sex.
Their favorite position is downward doggy style. In this position, Tsukasa pushes Senku’s upper body down and keeps his arms behind his back, and penetrates him from behind.
Animal-like poses turn Senku on more than anything, he loves when Tsukasa dominates him like this.
It’s a comfortable position for Senku because he can hide his embarrassment.
Tsukasa prefers it naturally so he will cum inside Senku.
Sometimes loves cumming in his own hands, then he will use his cum as a lubricant when he touches Senku’s member or when penetrates him with his fingers.
When Tsukasa is overwhelmed with lust, he can’t control himself and the animal inside him comes out.
Most of the time he doesn’t realize but he completely destroys Senku during the act.
The only thing Senku can do is ecstatically moaning and writhing in pleasure under Tsukasa.
He literally can’t walk the next day.
“How dare you did this you bastard??”
“Do you mean…hm…I wasn’t gentle enough?”
“I’m gonna kill you…!!”
