I (F24) realised my little brother's friend (18M) is hung like a donkey. So I sucked his soul out just to ruin all future blowjobs for him.

My little brother and his friends have always been kind of nerdy, always around to play DND or some kind of board games and video games down in the basement.

Sometimes is fun to mess with them when i see them. It's hilarious how badly they'd struggle to look me in the eye when talking to me.

Then I saw him coming out of the pool. I don't know if it was looking at me but it was clear he was aroused and then it became equally clear that holy hell, he was hung like a donkey. When he saw me staring at it he got instantly embarrassed and tried to hide it while walking by.

I didn't say anything to him about it but my evil mind got working and I started thinking 'but what if I blew him so nasty, his standard would be set so high for blowjobs that no other woman would be able to satisfy him again? He'd be thinking of me for the rest of his life.’

So the next weekend my brother has his friends staying round and playing late into the night. I was watching tv in the living room so they had to walk past me to get to the kitchen for any snacks. I saw him head through to the kitchen and ambushed him, standing between him and getting back to the basement and started talking to him. I got pretty flirty and teasing, touching his arm and stroking it and getting close. I could see him getting more and more flustered.

After a few minutes I heard one of his friends call up asking him what was taking him so long. He made a move to get past me but I put a hand on his chest and pushed him back and said 'you're not going anywhere, kid.’

He asked me what I meant, I reached down and took a hold of it through his tracksuit. It was like he was shocked by an electric fence! Then I did my best seductive face and said 'I'm gonna suck your dick.’

I didn't ask if he wanted it, just told him clearly I was going to do it. His face lit up so red, it was adorable. He was just going 'huh?' I was already stroking it back and forth realising he was rock hard, then kneeling down in front of him and pulling down his sweatpants. The thing sprung out at me and nearly hit me in the face!

I didnt even go slow, poor kid. I went straight to it. I wrapped one hand around his shaft, the other cupped and started massaging his balls. I slobbed and bobbed and gagged, the whole nine yards.
He was moaning and grunting and grabbing the counter top while I was just going to town on him. I think he managed to go 'please...' but that was all he managed.

Then someone else called from downstairs and the voice was closer saying 'what the hell is taking you so long?'

I could feel him tense up like he was freaking out. Then he whispered 'please stop, l'm gonna...' and I knew I had him.

I vigorously shook my head from side to side, making sure I was letting his shaft rub on the sides of my mouth, then I went back to my slobbery suction. Then my hand cupping his balls started tickling them.

It was instant the second I started tickling. The thing shuddered and just exploded in my mouth. It honestly caught me completely by surprise, the whole thing had only lasted about a minute. But I wanted to ruin him so l didn't even slow down. It was like a hose had gone off in my throat.

Then suddenly I felt his hand on the back of my head. I don't think he even realised he'd done it, like he was having a bit of a fit. I couldn't pull off as he just kept pumping cum in my mouth.

Then he let me go and just seemed to slump. But I didn't stop. Sucking merrily and tickling his balls till he got hard again. Kid was growling and whimpering for me to stop and wait up. I ignored him and kept going.

A few minutes later and I can feel it getting rock hard again and I know l'm gonna manage to make him cum again. I start humming and groaning and then he nuts again. I swallowed that down and carefully licked him clean.

I didn't even look him in the eye after I was done. Just patted him on the cheek and went 'I'll see you around, kid.’ And walked away without looking back.
