Sis had enough of NNN

Mike and his family went away for Thanksgiving. He and his friends decided to take NNN very seriously this year, they made a bet and all made it very far. Mike and his friend Pat were that last remaining member of the group. They took great pride in this and thought it was absolutely hilarious. But, it was starting to have a bigger impact on how he acted. He was obviously a lot more horny, but he was also much more aggressive and quick tempered. Mike and his younger sister Sophia were constantly arguing the entire time on the way down and the first day of the trip. She was being such a little brat and he he had absolutely no time for it, constantly snapping back and threatening to hurt her. She kept blaming it on his need to nut. The fact that she was saying it so freely pissed him off even more.

Sophia was a few years younger than him, much shorter and more petite but was a dancer and had a big and well shaped butt. She had bad thigh genetics so her butt looked especially plump. She wasn’t terrible attractive in the face but wasn’t ugly either. Mike’s friends often teased him about her perfect butt. She was a complete snob and her bratty demeanor is what set him off the most.

This was the furthest Mike had ever made it into November without nutting and was proud of himself, no chance he was going to fold now. But just about ever girl he looked at made him hard.

Sophia was adamant that he needed to nut because Mike was “getting out of line”. The second night they got in a serious fight before bed and Mike barked, “It’s not like you’re going to do anything about it!” and she responded smugly, “oh, is that so?”.

The next day she wore these tight jeans that fit her like leggings, her ass stretched them to the max. She kept walking right in front of Mike as their family was going on a tour of the town, sight seeing. Mike tried his hardest but his eyes would wonder to her ass every time he lost focus. He kept trying to snap himself out of it but she started to give him a chub. Knowing his bratty sister had that power over him right now really freaked him out. Because he couldn’t stop thinking about it, he eventually got a seriously demoralizing boner.

On top of that she sack tapped him every chance she got. Each one caused him to grunt and hunch over. It took everything for him to minimize his limp. She was so sneaky at hitting him in the balls with her knuckles or palm every time their parents weren’t looking. Eventually, when their parents went off to go look at something else, Mike broke down and begged her to have mercy. Hearing her douche bag older brother sound so desperate put the biggest smile on her face. It pained him to sound so submissive but his balls couldn’t take it anymore and his dick was going to explode. Every tap put his balls in more pain and put him closed to coming over the edge. To Mike’s confusion, Sophia said “sorry big bro!” then spun around like a dancer so her ass was facing him and flicked her foot up into his crotch.

Mike yelped upon contact and it felt like her foot was in his nuts for an hour when in reality she kept it their for maybe 2 seconds. Mike dropped to the ground holding his balls that had just been absolutely smashed but it was too late. The contact with her sneakered foot literally kicked the cum out of him. He clenched his fists and jaw as he realized what was happening. He couldn’t hide it, because of the build up the stain was noticeable.

She did it… that snotty bitch ruined his chance at completing No Nut November… and almost popped a nut.

Sophia, with her hands on her hips, now facing him said “sorry big bro, you needed to be put in your place.” Mike looked down, his ego was in absolute shambles to the point where he couldn’t even make eye contact with her. Maybe never again. Anytime they ever argued from this point on she could just bring this up and it would be over.

“Better go clean up! Don’t try this again next year. Even though it was fun, I don’t want to have to tame you like this again. Okay?”

“…Okay” Mike agreed, in no position to oppose her.

“And you might want to brush my dirty sneaker print off your crotch! HAHAHAHA” she said before laughing hysterically and skipping off.
