It gets harder

You follow your advise. Every time you get super horny, you imagine the embarrassment of cuming too fast. You visualize it very clearly. And it works!

Wow, your cute little sister really knows what she is doing. The next days however, this trick works less and less. The image of cuming prematurely becomes less interruptive of your sexual thoughts. Instead it seems to become a part of it. Connected, in a way.

You also notice sth else. The more days pass, the more attractive your little sister seems to become to you. What the fuck, she’s your sister! It must be really bad, if even she already starts to look tempting. But she’s the only female you see these days. You really need to make it through this week.

On the last day, you come to your sisters room. She looks so hot to you right now. She doesn’t even wear something special, but somehow it drives you crazy. The shape of her legs in these loose, thin pants.. Her young and perky breasts, stretching her thin top…

Dude, control yourself. This is fucked up. You talk to her normally, and describe your ‘progress’ and problems.

Sister: “Thats strange. How can you get so horny still? From what? You dont watch porn, I put a safety password on your devices like we said, so you cant. You dont even see women, you are just home with me…. Don’t tell me..”

You: “Nono its not that! You’re my sister!”

Sister, looking at you mischievously: “Alright then.. That’s good. Because I was about to suggest, if the trick with thinking about cuming prematurely doesnt work so well anymore, you can also try thinking about me.”

You: “About you?”

Sister: “Yes. I’m your sister after all, that will always take you out of your sexual thoughts.”

You: “Youre right, of course.”

Sister: “The most fool proof, of course, is if you use both. Think about the embarrassment of the premie and think about me. Than you should be back in control immediately”

You: “Alright.”
