"Huh" Before Tzuyu can respond, he's been push to the sink and by that Sana stroke his bulge while giving kisses on his neck.
She's too horny
"B-baby" 
"Stop me Tzu" She suck his neck down to his chest then take off his boxer. His big cock sprung out proudly.
Sana take his cock in her mouth and skillfully pump it faster. She even swirls her tongue around the tip of his cock.
"Ahh~ oh baby your mouth...so warm" He hold Sana's head to make her go deeper. Sana almost choke on it but she handle it like an expert.
She pump it faster then slower after that taking it to her mouth again. She lick his cock then to his balls. 
When he's about to cum, Tzuyu pull her up and lift Sana up to the sink. 
"I'm gonna make you cum before I do if you let me my Love" He grab his cock and grind it against her pussy. 
Sana moan on the touch, she felt the warm cock and push his hips with her legs.
"Fuck me baby I need it" Tzuyu then insert his cock into the warm cave. He moan when he felt the familiar warm.
Sana pull his nape for kisses. Tzuyu pound slowly while kissing her. Sana's body jolt up with the slow yet hard thrust. Even though she feel so sore but the pleasure take over her.
"Faster baby..fuck me more" Tzuyu speed up his thrust and fuck her until her mind flew back to Japan. 
When he felt Sana's getting tight indicating she's near, he goes faster than before. He's almost near too.
"Let's cum together Tzu" Sana spread her leg more wider to make it more deeper. A few thrust later, both of them come. Tzuyu spurt his seed on Sana's body. 
Both of them pant heavily until Tzuyu had to rest his head on her shoulder. 
"It feel so good Tzuyu~ah" Sana caress his hair and kiss his forehead.
"I'm glad to know that you're feeling good about it my Love...now let's take shower together" Tzuyu give a quick peck before turning on the pipe.
Hour later, both of them finally came down with Sana been carried by Tzuyu. Sana stare at how handsome he is. 
She realised that, no other man will look like him. No other man will replace him. No one can be the same as her man. 
"I love you Tzu, I will never get tired of saying this to you" She said it when Tzuyu let her down. 
"I love you too Sana" The servant, butler witnessing them. It gives them newly married couples vibes. 
Sana then prepare his plate, putting the rice and other dishes to his plate then on her plate too. In the mid of their breakfast, someone ringing the bell.
The butler then goes to check the door. 
"Who is it" 
"My boy" Tzuyu's dad came and hug him. Tzuyu was surprised to see them here.
"D-dad, m-mom" 
"My baby boy and oh...are you Sana, you're so beautiful in person" Mrs. Chou goes to Sana instead of Tzuyu. She gave her a hug.
Sana also surprised and speechless. She expects to see them at Tzuyu's hometown but to her surprise, she met his parents right now. 
Luckily she dress up casually. If they didn't get shower earlier, probably still wearing nightrob without wearing anything beneath.
