You didn’t have sex with her yet.

“Well…we didn’t do it yet.” You admit.

“Really?” Your sister says excited.

You: “We are planning to do it soon, on our anniversary.”

Sister: “And do you think you will last long enough to satisfy her?”

You: “Well, i guess…I havent thought about it. But I dont think I’m the kind of guy who would cum too fas…wait why are we talking about this?

Sister: “Dont you think it would be super exciting if you came far too early? That would be so funny!”

You: “No, it would not.”

Sister: “Well, in that case you should train. I can help you.”

You: “How can you help me? Didn’t you just visit all these pages about making guys cum faster?”

Sister: “Yes, but if you want to last longer, I simply have to do the opposite of what these women do to make the guys cum faster. Easy.”

You: “And I can trust you with that?”

Sister: ”Of course. This is just fantasy with these internet guys, but you are my brother. I just want your best. Like you just want my best.”

You: “So…how would this training look like?”

Sister: ”First step is, to not jerk off for the next week. You have to keep your hands to yourself. No touching. No porn. Nothing. We have to rewind your brain from all these sexual influences, otherwise you will cum far too fast!”
