Sarah burst into the shared bedroom, her eyes sparkling with mischief. "Hey, Jake," she called out, causing her 14-year-old brother to pause his video game and blush.
"What's up, Sarah?" he asked, trying to sound cool but failing miserably.
Sarah sauntered over to where Jake was sitting, a smirk playing on her lips. "I was just wondering... do you know anything about sperm?"
Jake's blush deepened, and he stuttered, "W-what? Why do you want to know that?"
Sarah rolled her eyes and playfully insulted him, "Come on, Jake. You're almost 15, and you still don't know about sperm? You're such a late bloomer, a spermless wonder."
Jake's competitive spirit ignited, and he determinedly said, "I'll show you my sperm."
Sarah raised an eyebrow, "Oh, really? And how do you plan on doing that?"
Jake hesitated, causing Sarah to roll her eyes and tell him to "man up."
With a determined look on his face, Jake got up and went to the bathroom. Sarah waited impatiently, making fun of Jake's "delicate" sensibilities.
A few minutes later, Jake returned with a small amount of sperm on a tissue. Sarah inspected it, making disgusted faces and playfully insulting Jake's "tiny" contribution.
Jake, feeling embarrassed, tried to take the tissue back, but Sarah playfully refused, teasing him about his "baby-sized" sperm.
Jake, determined to prove himself, suggested they try again tomorrow. Sarah, amused by Jake's determination, agreed.
The siblings continued to banter and playfully insult each other as they went to sleep. The chapter ended with Sarah victoriously holding the tissue with Jake's sperm, while Jake looked on with a mix of embarrassment and determination.
