Warning: NSFW content! These HCs are just my imaginations, If you donāt like this ship, please keep scrolling. But if you like TsukaSen read them ~Ā Anyway, sorry for the grammar mistakes, my Tsukasen shipper heart blinds me as fuck.
Tsukasa is a loving and caring man who adores Senkuās intelligence. He is always protective and gentle with his smol scientist.
He is Senkuās ābodyguardā 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 canāt hide his excitement when Tsukasa whispers praising words in his ears. His gentle and erotic voice makes him melt.
But he immediately realizes Tsukasaās true intention when he feels butterfly kisses on his neck and Tsukasaās hand touches his skin under the clothes.
Itās very obvious that he wants to have sex with him.
ā..Stop itā¦.or do it quicklyā¦.ā
Senku prefers quickies when he is in the mood, but Tsukasa feels awkward because he doesnāt understand the meaning of āquickiesā.
āWhat do you mean?ā
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 doesnāt have time for this, especially during the day.
So he will be mad at him, as expected.
āI mean you should hold back yourselfā¦Iām in the middle of the workā¦ā
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 canāt handle his sensual kisses and touches.
Tsukasaās loving behavior makes Senku completely submissive, he canāt say no to him.
They stare into each otherās eyes and keep eye contact for long minutes, while Tsukasa gently caresses Senkuās 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 Tsukasaās huge and strong hands caress Senkuās slim body, Senku realizes that he has no chance to escape Tsukasaās claws.
Senku is freaking out, especially after he realizes that Tsukasaās dominance and beast-like strength actually turns him on.
Tsukasa always goes slowly, he carefully licks, bites, and sucks Senkuās most sensitive body parts.
Senku feels like Tsukasa would eat him alive, but he holds back himself.
Senkuās 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 Senkuās butt, sometimes leaves love bites on him.
Senku completely loses his mind during the foreplay because of Tsukasaās sensual and slow movements.
Tsukasa literally can spend hours worshiping Senkuās body.
Senkuās member visibly pulsates because of his teasing touches.
When Tsukasa finally touches Senkuās hardness, he needs only a few movements to cumming.
Senku never experienced such an intense orgasm before, his whole body is shaking and he canāt 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 Senkuās forehead.
Tsukasa always stops right after the foreplay, as long as he gets Senkuās 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 doesnāt 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 Senkuās 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.
Itās 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 Senkuās member or when penetrates him with his fingers.
When Tsukasa is overwhelmed with lust, he canāt control himself and the animal inside him comes out.
Most of the time he doesnāt 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 canāt walk the next day.
āHow dare you did this you bastard??ā
āDo you meanā¦hmā¦I wasnāt gentle enough?ā
āIām gonna kill youā¦!!ā
