Warnings incest.

When you asked him he did not know what to think. Weren't you a Jr now? In highschool? And you did not know to kiss? He rolled his eyes at you getting up from his computer chair sulking over to you . You sunk into the wall the closer he got , berating you the whole way about your silly question till he was inches from your face .

He mumbled under his breath about how stupid you were and grabbed your cheek with his pinkie up. “You don't have to do much idiot.” His lips connected with yours and in the same second your knees gave out from under you. He caught you with his free arm still kissing you , even with chapped lips it was nice. Your stomach twisted all around as Tomura leaned into you parting his lips for his tongue to enter your mouth. You dug your nails into his shirt parting your lips so his tongue could slip in . Tomura pressed himself on you, shoving his tongue down your throat and squeezing your side .

At some point Tomura pulled away to see your beet red face and wide eyes staring back at him. Tomura clicked his teeth. So dense, you probably had no idea how to do anything else either huh? A smile crept up his cheek as he looked back at you, “Dear Sister…”

Before you could respond Tomura grabbed your shirt dragging you to the bed to sit down with him in front of you, arms folded over his chest. Tomura instructed you to unzip him and your gaze shot up at him with confusion written all over your face. He smirked stepping closer. “You heard me.” He rubbed his lap on your face. “You want to impress this loser right? You need to know how to please him. So unzip. Me.”

You moved away from his lap rubbing your face for a second trying to figure out if this was really happening. Tomura was your big brother , but he was just trying to help right? It should be okay. Slowly you extended your arms to his zipper only for Tomura to poke your forehead. “No hands.” He ordered. You opened your mouth to question him but he just tapped your forehead again and pointed to your mouth.

It took you a minute to figure out the right movements and finding the zipper with your teeth . Tomura was growing impatient but you need to know how to do this. And it was amusing watching your head move all around his lap. Your bottom teeth hit the zipper and you bit down moving your head down unzipping him .

His semi hard cock fell out hitting your face with a light thud . Tomura smirked down at you bucking his hips forward till his cock fell out of his boxers. “Lick me, dear sister.” He ran a hand through your hair talking with a sinister tone on his tongue. He rolled his hips making his cock hit your cheek a few times . You opened your mouth letting your little tongue creep out hitting the head of his cock. A quiet moan fell off Tomuras lips .

“Good. Now move it.” He said peering down at your flushed face. You moved your wet tongue all along the head of his cock staring right at it, watching it get slightly shiny from your saliva . “What a good sister you are, this will surely help you out with that foolish boy you like.” You spent a half hour following Tomuras instructions, licking from the base of his cock all the way to the head, giving it little kisses when he did not ask for them. You were a fast learner it seemed like. You knew how to take care of his hard cock without him having to correct you.

Soon enough you were bobbing your head on his length taking almost all of him in your mouth. By now Tomura was rocking his hips into your head watching his cock slip in and out of your mouth , his release building inside him getting stronger and stronger. “St-stay still.” He huffed out grabbing your hair with his thumb up.

You slowed to a stop so he could shove his whole cock down your throat. “Dont you dare spill any.” He said grunting finally releasing down your throat.

You whimpered feeling his cum slither down your throat . You looked up with watery eyes and Tomura pulled out letting go of your hair to shut your mouth forcing you to swallow. “Good little sister, you did great. Not get on all fours, we're not done.”
