The Kid Brother
An SPH Experience by sizeguy69.
Especially sex.
That was the thing about our group. We shared everything: hookup stories, first times, weird kinks, embarrassing failures. Nothing was sacred. The girls would give the guys tips on what women actually wanted in bed. The guys would explain what we really thought about when we were going down on someone. It was open, honest, and incredibly entertaining.
Some of the group hooked up over the years. Nothing serious, just drunken experiments that we all found out about eventually because nobody in our group could keep a secret. Two of the girls hooked up with one of the guys at different parties. Another girl made out with the other guy once and then declared him “too aggressive” and never let it happen again. One of the girls briefly dated someone outside the group and came back with stories that made all of us blush.
But me? I was firmly, permanently, unquestionably friend-zoned.
It wasn’t like I hadn’t tried. Freshman year, I had a massive crush on one of the girls. I flirted, I hinted, I even worked up the courage to ask her to a movie once. She’d blinked at me for a second, then laughed like I’d told a joke and said, “You’re adorable. Let’s just keep it friends, okay?”
That was the end of that.
The other girls treated me the same way. Affectionate but never interested. They’d hug me, lean on me, fall asleep on my shoulder during movie nights. They’d change in front of me sometimes because “it doesn’t matter, you’re basically one of us.” They’d ask my opinion on their outfits and then ignore what I said.
And they’d talk about their sex lives in graphic detail while I sat there, listening, trying not to squirm.
It wasn’t always easy, but I’d made peace with it. Being the safe, non-threatening guy in the group had its perks. I was close to them in a way the other guys weren’t. They trusted me. Confided in me. And yeah, sometimes I went home and jerked off thinking about them, but that was just part of the deal.
The beer pong game started like any other night.
We were crammed into one of the girls’ apartments—the one with the big living room and the plastic folding table that was perfect for pong. Someone had put on a playlist, something low and vibey, and the air smelled like cheap beer and weed smoke. We’d been drinking for a couple hours already, everyone loose and laughing, when someone suggested we make the game interesting.
“Strip beer pong,” one of the girls announced, holding up a Ping-Pong ball like a trophy. “Every time you lose, you take something off.”
There was some joking resistance, mostly from the guys, but eventually we all agreed. The rules were simple: two on each side, loser removes an article of clothing. We’d rotate partners every few rounds to keep it fair.
I should have known I was in trouble.
The first few rounds were uneventful. The other guys lost their shirts first, showing off their gym-earned physiques while the girls let out exaggerated wolf whistles and pretended to fan themselves. The girls lost their socks and shoes, making a big show of peeling them off as if it were some kind of burlesque performance.
Then my team lost again, and I had to lose my jeans.
I stood there in my boxers and t-shirt, feeling the cool air on my legs. The girls giggled, nudging each other. One of them said something I didn’t catch, and they all burst out laughing.
“What?” I asked, suddenly self-conscious.
“Nothing,” she said, her eyes twinkling. “You just have very… adorable legs.”
That should have been my warning.
The next loss took my shirt. Then another took my socks. And then, because the universe has a sick sense of humor, my team lost the final round, and I was staring at the table, realizing I had exactly one article of clothing left.
“No way,” I said, shaking my head. “I’m not taking off my boxers.”
“Rules are rules!” one of the girls crowed. “You lost. Take ’em off.”
“Come on, man,” one of the guys said, grinning. “We’ve all seen it before. Just do it.”
That was true. Shared bathroom situations, skinny dipping once at a lake house, that one time I got drunk and jumped in the pool in my underwear, which ended up being less than opaque. The guys had seen me naked before.
But the girls hadn’t.
Not really.
I hesitated, and that hesitation somehow made it worse. Like I was confirming something they already suspected.
“Just do it, dude,” the other guy said, more gently this time. “We’ll all be too drunk to remember anyway.”
So I did.
I hooked my thumbs into the waistband of my boxers, pulled them down, stepped out, and kicked them aside. For a moment, I just stood there, completely naked in a room full of my closest friends, my soft cock hanging between my legs in all its unimpressive glory.
The room went quiet for about half a second.
Then one of the girls let out a little snort of laughter, and the dam broke.
“Oh my god,” she said, her hand covering her mouth. “That’s… that’s really it?”
“It’s so tiny!” another one added, not even trying to hide her giggle. “I mean, I knew you were small, but seeing it like this…”
“It’s like a little button,” the third girl said, her eyes fixed on my crotch with undisguised fascination. “Just this cute little nub.”
The fourth girl didn’t say anything. She was too busy laughing.
I stood there, my face burning, my heart pounding. My cock, which had been hanging there soft and useless, now felt like it was somehow shrinking even further. The guys were laughing too, but it was more sympathetic, more “we’ve been there man” energy. The girls were just… amused.
“It’s so funny to be around a guy that’s so small,” one of them said, wiping tears from her eyes. “His cock is not sexual at all. Just a cute little nub.”
She giggled again, and the others joined in.
Another one added, “Yeah, it’s not very awkward or embarrassing when it’s little and one that we never would suck or fuck. No offense, you’re just like our kid brother more than a sexual partner.”
I froze.
The words hit me like a physical blow. I understood exactly what they meant. Me, my body, my cock—none of it was a sexual option for them. I wasn’t a potential partner. I wasn’t even a temptation. I was a novelty. A cute, funny, non-threatening presence that they could be comfortable around because I posed zero sexual threat.
“I need a drink,” I muttered, grabbing my cup and taking a long swallow.
The girls continued their conversation as if I hadn’t spoken. They were still glancing at my exposed crotch, still giggling, still making little comments about how “adorable” and “sweet” and “harmless” I looked.
“Like, if one of the other guys was standing there naked,” one of them said, gesturing vaguely at the two guys who were now laughing awkwardly, “it would be weird. I’d feel like I had to do something or look away. But with him…”
“It’s just funny,” another girl finished. “It’s not a penis, it’s more like a… decoration.”
They all burst out laughing again.
I should have been mortified. And I was, partly. My face was hot, my ears were ringing, and some primal part of my brain was screaming at me to cover up, to run, to do anything to escape the humiliation.
But there was another part of me. A darker, more twisted part that I’d never fully acknowledged before that night. And that part was absolutely reveling in this.
My heart was racing. My skin was tingling. And as I stood there, naked and exposed, listening to the women I’d known for years casually dismiss my manhood, I felt a surge of arousal so intense it almost made me dizzy.
I was getting hard.
No, no, no, I thought desperately, trying to will it down. Not now. Please not now.
But it was already happening. My traitorous cock, which had been soft and small before, was now beginning to swell. It didn’t get much bigger, being only a few inches at full mast, but the change was noticeable enough to draw attention.
“Oh my god, is he getting hard?” one of the girls shrieked.
“Aww, he likes it!” another cooed. “Look at his little hard-on. It’s like a baby carrot.”
“Does it even count as a hard-on if it’s still under three inches?” someone else asked, and they all howled with laughter.
I wanted to cover myself. I wanted to run. I wanted to sink into the floor and disappear. But I couldn’t move. The humiliation and the arousal had short-circuited my brain, leaving me frozen in place, my pathetic erection bobbing slightly with each heartbeat as my friends continued to mock me.
“Seriously though, we should probably let him put his clothes back on,” one of the guys said, but even he was struggling not to laugh.
“No way,” a girl protested. “He lost fair and square. Let him stay naked.”
“Yeah, it’s not like it’s a big deal,” another added. “Literally.” More laughter.
I ended up staying naked for the rest of the night.
It became a running joke. Every time I moved, someone would comment on my “little guy,” my “cute button,” or my “innie.” The girls started calling me “Nub,” “Kid Brother,” and “Little Buddy.” They’d ask me to grab them drinks and then thank me with pats on the head like I was a well-behaved dog.
“It’s just crazy,” one of them said at one point, leaning back on the couch with a drink in her hand. “Like, we’re all sitting here with a naked guy, and nobody cares. Because it’s you. You’re not a naked man, you’re just… you know. You.”
“Yeah, you’re basically one of the girls at this point,” another agreed. “Except with that tiny little thing instead of a pussy.”
“I think I’d rather have a pussy,” a third girl said, and they all laughed again.
I sat on an ottoman in the corner, my hands loosely covering my lap, my dick still stubbornly half-hard despite everything. The girls had stopped looking at me directly, which was somehow worse. They’d moved on to other topics of conversation, occasionally glancing my way and smirking, as if I were a piece of furniture that had somehow wandered into the room.
“You know what we should do?” one of them asked suddenly. “We should measure it. For science.”
“What? No,” I said, my voice cracking.
“Come on, it’ll be fun,” she wheedled. “We want to know exactly how small it is. We’ve been guessing all night.”
“I haven’t been guessing,” another girl said. “I’ve been assuming it’s somewhere between ‘why bother’ and ‘is that a belly button?'”
They all laughed, and I felt my face go red again.
“Please don’t,” I said weakly.
“Please do,” she countered, grinning. “You owe us. You’ve been walking around with your little worm out all night. The least you can do is let us satisfy our curiosity.”
The other girls chimed in with encouraging words, and even the guys seemed to be enjoying my discomfort. I looked around the room, searching for any sign of mercy, and found none.
“Fine,” I heard myself say, my voice barely above a whisper. “But there’s nothing to measure.”
One of the girls produced a ruler from somewhere—I still don’t know where she found it—and approached me with gleeful curiosity. I dropped my hands, exposing my shriveled cock to the room.
It was maybe two inches soft. Softer than soft, honestly, after all the attention and laughter. It had retreated into itself, leaving just a small protrusion of skin and a pair of tiny balls pulled up tight against my body.
“Oh my god,” she breathed, holding the ruler up. “Two inches. Maybe two and a quarter if we’re being generous.”
“Not even hard, though,” another girl pointed out. “It was bigger earlier. You know, relatively speaking.”
“That wasn’t much bigger. Maybe four, four and a half,” the guy who’d seen me in the locker room offered.
“Four inches hard?” one of the girls shrieked. “That’s insane. That’s like… porn star inverted.”
“Alright, that’s enough,” I said, finally finding some of my dignity. “You’ve had your fun. Can I at least put my boxers back on?”
They let me, eventually. The jokes continued for the rest of the night, but the intensity faded. By the time we all passed out on various couches and air mattresses, it felt almost normal again. Just another night with the crew.
Except it wasn’t.
When I got back to my apartment the next morning, still half-drunk and fully exhausted, I stumbled into my bedroom and collapsed on the bed. And then I lay there, staring at the ceiling, replaying every moment of the night before in vivid, painful detail.
His cock is not sexual at all. Just a cute little nub.
One that we never would suck or fuck.
You’re just like our kid brother more than a sexual partner.
The words echoed in my skull, and even after a full night of humiliation, even after being laughed at and measured and dismissed by every single person I considered a close friend, my body responded.
I was hard. Fully, desperately hard.
I wrapped my hand around my small, insignificant erection and started to stroke, my mind flooded with images from the night before. The girls’ faces as they laughed at me. The sound of their voices as they described my body as non-sexual. The feeling of standing naked in front of them, exposed and powerless, while they casually debated whether my cock even qualified as a penis.
It was wrong. I knew it was wrong. Normal people didn’t get off on being mocked and humiliated.
But I wasn’t normal. Not anymore.
I came harder than I had in months, spurting onto my stomach with a choked moan, my body shaking. And as I lay there in the aftermath, covered in my own cum, I realized that something had fundamentally shifted inside me.
The girls hadn’t just humiliated me. They’d unlocked something. Something dark and desperate and hungry that I’d spent the rest of my life trying to understand.
And the truth, the part that scared me the most, was that I’d never felt more alive than in that moment, naked and small and completely, utterly, irreversibly emasculated in front of everyone I knew.
The End.
