I have a few stories where my brother humiliated me for having a tiny penis but I’ll start off with the story when he found out how small I really am.
This happened around a few years after I graduated high school so it’s been awhile now. We were outside in the backyard grilling food for a party. He kept annoying me and hitting me so I wanted to get him good to put a stop to it. When he wasn’t looking I slapped him hard in the crotch causing him to drop to his knees. I laughed so hard at him which in hindsight wasn’t good for me since this made him want to get revenge even more now. I will say he didn’t feel that big which he probably thought I would expose his size, but he was way bigger than me…
Some time passed as he recovered waiting for his moment to strike. By this time I had put the whole situation behind me thinking we were “even” and oh man was I completely wrong. The party was ending so we started cleaning up. I was folding up tables and chairs then putting everything away. We store our tables on this top shelf so as I was putting it up there my brother snuck up behind me.
I will say wearing basketball shorts was a horrible mistake. He yanked them down as they wrapped my ankles, luckily he didn’t pull down my boxer briefs, but unlucky on what happened next.
I was shocked at what just happened and before I could react I froze in place at what I just felt. My brother swung his arm between my legs and GRABBED my crotch. I literally whimpered in pain begging him to let go. It was only a light fabric “protecting” my modesty but I was practically naked and I know he could feel every. single. inch. I think initially he was shocked too at how little he was grabbing. Then I heard him laugh knowing he had all the power in his hand (literally) and that he was bigger than me down there. He leaned over to look at my crotch and saw my tiny package being squeezed in his hand.
“Wow you really are my LITTLE brother” is what he said before laughing even more. He moved his fingers around to get a good feel of my tiny balls and little cock to make sure he had everything. “It’s like 3 marbles in a tiny sack” he took a final jab at me. My body didn’t know how to react because my dick started getting hard from the humiliation. I think he felt one of my “marbles” twitch and start to grow is when he let go of my crotch as I fell to the ground holding my little package as I tried pulling up my shorts. “That’s payback for earlier and never try to mess with me again” he said as he left. Safe to say I avoided him the rest of the day and not sure if he exposed my size to anyone else.
