Why did it have to be nudism?
My little brother announced during dinner on his 18th birthday that he was becoming a nudist. Stunned silence. "Thoughts? Anyone?"
After what seemed like an eternity, our mom managed to swallow her bite of food and spoke. "A-a-a-a nudist? As in walking around in nothing but what the Lord gave you?"
"Yep! That's exactly it."
Now it was Dad's turn to find his voice. "Not under my roof, you're not. I'll not have you parading your penis around in front of these ladies, causing who knows what unholy thoughts to swim through their heads."
Too late. I had actually seen my brother's penis once as he got out of the shower at the same time I had entered the bathroom. He hadn't gotten the door latched all the way and it had swung partially open during his shower. I had come back from work early due to a power outage in the building. Thinking the bathroom was vacant, I had walked in and saw more than any sister is supposed to see of her brother. After a lot of apologizing and scrambling for towel and door handle respectively, and a bit more than my fair share of staring, we managed to find ourselves separated by a closed door once again. That had been my first ever live penis viewing, and honestly, i wanted to see more.
"Now, honey. There's no need to be so hastey. Let's discuss this. Darling, what your father is trying to say, I believe, is that it's not right for you to expose yourself to everyone without their permission, especially when they are your family. What you do in your own room is your business, though. If you want to strip down and enjoy some fresh air down their in your own room, I think we might be able to accommodate that. What do you think, Dear?" Our mother, always the peacemaker, now put the proverbial ball in dad's court, but with her promise on the table, he could stand his ground and she would support him, but their marriage bed would feel awfully cold that night, or support her and possibly get the opportunity to stress test the bedframe later.
"All right, but if I see your dangly bits outside of your room, I'll have them mounted to my wall." An empty threat on the surface, but we all knew what he meant.
With an solemn face, my brother thought about the terms for a few seconds before his face broke into a mischievou grin. "Deal." He was gone from the table and sprinting for his room before anybody could say another word.
With a grumble, dad lifted himself from his chair and, with a peck on mom's forehead, said "I'm off to work. Let me know if I need to come home at any point." With a glance down the hall, he headed for the front door and off to work.
I gave him a couple minutes to make sure he was in the car and cleared the driveway before whirling on mom. "Nudists? Please?"
With a loving smile and a flourish, she pulled her blouse up and over her head. As she reached around behind her to unclip her bra, she said in a conspiratorial tone "Let's go uncage your brother. This should go without saying, but this stays just between us."
Less than a minute later, we were standing completely nude in front of my brother's bedroom door. Mom led the way in without knocking, and stopped so suddenly that my breasts pressed firmly into her back before I could stop. I looked over her shoulder to see what caused the traffic jam. My brother was laying on his back on his bed with his phone in one hand, directly above him strraming porn, his other hand firmly gripping and stroking his cock. Still the biggest, most beautiful, and only cock I had ever seen. We both stood there motionless, my tits still pressed against my mom's back, nipples trying to bore holes through her and pussy juices flowing down my leg while we watched him stroke faster and faster. His breathing got shallower, his face redder. All of a sudden he tensed and erupted cum high into the air. As it arched up and came back down on his stomach and chest with an audible splat, mom finally found her legs and began moving forward with me moving to her left at the same pace, our eyes still transfixed on the sex rod that had just produced the copious mess in front of us. With a great sigh and one last jerk of his hips, he lowered the phone while softly stroking the last bit of cum from his softening phallus.
