It was Tuesday morning and I met up with some friends in the university coffee shop. There were six of us, myself; my muscular friend Anthony who was dating my sister and I thought was a dick, my other friend Steven and the girls Hattie, Lucy and my little sister Alice. We didn’t have anything planned for today so when Hattie suggested we all go swimming since it would be empty this early it was met by the others with eagerness.

A little background about myself here wouldn’t be amiss, so I was in good shape and a good looking guy even better than that fool Anthony, but I had a little secret, “little” being the operative word here since no girl who had ever seen my penis had described it as anything but. I know size isn’t everything but my penis was slightly less than 2 inches erect and flaccid it was not much more than a stub. Due to the way my penis was so small it did not lie to the left or right it just stuck straight out so I would always stuff a sock in my pants to try and create the illusion of a bulge.

I didn’t really want to go swimming with everyone but the opportunity to see my little sister in a bikini up close was too good to miss out on. I had spent countless nights jerking myself to her pictures from her holidays to Greece. Plus I figured I could just stuff my bathing suit to avoid any suspicion.

So we went back to our rooms to grab our things and met up at the pool and I was not disappointed my little sisters hot body in her bathing suit made my little soldier perk up to his full size. We were having a great time and started diving into the pool. Anthony dove of the highest board and eager to not be outdone I did the same.

That was when disaster struck, my sock which I had taped down came loose with the force of the dive so when I emerged with a big smile on my face it was short lived.

“Cold in there is it?” Hattie joked and everyone laughed. I tried to play it cool and attempted to get back to the dressing room to fix this as the water made my suit cling to my body revealing my shame.

That was until my sister found the sock floating in the water.

“What’s this?” she asked quizzically her sweet innocent face not understanding, Hattie walked over took a quick look and then turned to me.

“You’ve been stuffing your suit to make your tiny cock look bigger haven’t you?” she put to me.

“No, what the fuck are you talking about?”

“Prove it”

“No don’t be silly-“ I was cut short by Anthony yanking my bathing suits to my knees. I was like a deer in headlights my manhood clear for everyone too see. Hattie and Lucy were both hysterically laughing already.

“My, my that is a very small penis indeed isn’t it? It must really suck to have such a hot sister when your penis is almost non-existent”

I don’t know why I didn’t run away but the humiliation was turning me on. My little dick started to stiffen which made them all laugh harder.

“Cover yourself up bro, why the hell do you have a boner?” little sis seemed confused by the situation.

“Its because he likes it Alice, he likes it when we tell him he’s not even a man and that his worm should be called a dicklet since its so small. Go on, don’t be shy, tell your little sister what a sad loser you really are”

There was no going back, I looked her dead in the eyes and admitted “I sneak into your room at night to sniff your panties, and I don’t watch any porn I just jerk off to your facebook holiday pictures every night.” I could see the disgust mixed with pity in her eyes but I had to degrade myself further my cock was almost ready to blow.

“So when Anthony comes over to fuck your sister, what do you do? Do you sit at her door listening in, playing with your baby dicklet dreaming of being a real man?” Hattie gleefully chimed in.

“No, I do listen in but I know I’ll never be enough to satisfy her I just want to serve her” I could see my little sisters expression start to change, she was beginning to enjoy this.

“This why you’re always offering to give me a foot massage isn’t it? Do my feet make you hot? Come over here and show lil sis how big my brothers baby boner can get” I could see the evil intent in her eyes but in her bathing suits she looked like I goddess I was powerless.

She grabbed me by the balls and using an app on her phone I measured in at a puny 1.8 inches. Then she pulled me closer and whispered in my ear “Fuck me bro, do me like you’ve always dreamed of”

She jumped up naked and spread her legs but as I positioned myself she kept her hands in the way, the small space she had created with this barrier was just enough to keep my tiny pecker from entering her. I started thrusting furiously but my penis just wasn’t long enough to enter her so I must have looked ridiculous pumping into thin air.

I could hear them all laughing even that bastard Anthony and as I looked into my sister’s eyes I could see her disdain for me. He total lack of regard for me as a man, this was too much for me. I began pumping air as fast as I let out a little squeak

“ Oh my god bro, is that cum dribbling out of your micro dick? This is just precious not only do you not have a real dick you came in less than 30 seconds and you could only manage a dribble at that!”

I tried to say something to defend myself but nothing would come out I just backed away from her overcome by the situation. I could see Antony had his cock out fully erect, my penis was becoming flaccid so as we stood next to each other I can only imagine how pathetic my half and inch almost retracted cocklet looked like next to his 8 inch masterpiece.

My sister had put her suit back on and she strode towards me with one hand she wiped the cum of my dicky and with the other she held me by the chin, as one holds a child you are scolding. She looked deep into my eyes and commanded

“Eat it”

So I had no choice, there naked infront of all my friends I licked my own cum of my little sisters fingers with my tiny penis already starting to stiffen again. I don’t know what tomorrow will bring but I can only hope its more humiliation.

 shes picked up on how submissive i am towards her because i offered to massage her feet and legs abit too often.

shes seen my tiny cock in the shower, another time i pretended to fall asleep while wanking and she saw. also when i hang out her room i wear thin material bottoms to show my little boner. i even try to brush it agaisnt her back when standing behind her.

although she hasnt told me i have a tiny cock, she does still let me massage he feet and do chores for her but reminds me of how much a loser i am with no friends.

recently shes taken to making me look bad infront of our mother. just insinuating all i do is sit in my room and play video games (code for masterbate), and i for sure know shes told her friends by how they treat me and knows i take her panties
