The sun rose over the horizon; it was already morning. My hands are on either side of your head, balled up in a fist. Eyes searching your face while your moans echoed throughout the room.

***Plap Plap Plap***

My body claps against yours repeatedly. “Seriously? All this to make me lose No Nut November?” You’d feel that thick cock repeatedly stretching your insides as my raw cock pumped in and out, our bodies rocking the bed to make the bedpost in your room knock into the wall every time I plowed into your wet depths.

“Mom and Dad are going to assume you and your boyfriend went at it all night. What are you going to tell them?” I snickered, breathing heavily in between every couple of words. I leaned back, hands grabbing onto those hips of yours while your back arched. “I’m close!” I blurted out. Your own stepbrother was about to bust a nut into your pussy. All because you found out what No Nut November was and that he was participating.

A flashback ensued, going back to the beginning of the day. You were just waking up. You could hear me talking to a bunch of friends about not nutting the entire month, spouting the word "No Nut November" over and over in my room as you walked by. "I'm going to do it, man, definitely not going to crack this year!" It was like clockwork, your step bro back for fall break, only to be that annoying brat that couldn't keep his mouth shut between those thin walls that separated our rooms. You, having graduated, had already gone through all this before with fuckboys and dating, all of it. You were finally in a happy relationship with your boyfriend, the only thing you weren’t getting was a deep dicking. After doing some research on No Nut November, finding out that it was a month where men abstained from busting a nut, whether it was female-driven or self-driven, the goal was to not crack, and if one did, they'd lose major respect in their friend group. This may have sparked something inside of you. Was it the competition? Making him lose? Bragging rights? Embarrassing him? Or were you just craving a stud?

Step sis needs to make sure step bro busts before the end of the month. It's what any good sibling would do, right? Make sure he loses and all his friends know!

—————————-

What will you do? Either resume the scene by walking into my room then and there, or carry on the day with your step bro, teasing him until he can’t take it anymore and cracks. Maybe some sly conversations, bickering, and somehow we end up doing something we shouldn't.

[M4F] 14 Days into No Nut November and I am already an aching and throbbing mess, my snow bunny step sis could see that and finds ways to encourage me to break. She is constantly brushing against me, eyeing me down, and now sitting in my lap! I know she can feel it. "H.. Hey what are you doing?"
