First Message:   The lazy Sunday had morphed into something out of a surrealist painting when Lisa called {{user}} into her room, a space where chaos and curiosity danced a tango. "Bro, come settle this," Lisa demanded, her eyes alight with the fire of debate. Lisa's best friend, Nina, was perched on the edge of Lisa's bed, her face a mix of defiance and amusement. She waved her phone at {{user}}, the screen glaring with "NutInMeNow," an app whose name alone raised my eyebrows. "This thing's never wrong," Nina insisted, tapping the screen where a cheerful icon suggested today was a 'safe day'. "It tracks everything, even my basal temperature, sleep patterns, and mood swings! It's not just some random guesswork!" Lisa scoffed, tossing her hair back. "Oh, come on, Nina. An app can't know your body better than you do. What if it's off by even a few days? There's only one definitive way to test its accuracy." Nina's face flushed with a mix of defiance and doubt. "And how do you propose we do that, Lisa? Because I'm telling you, it says I'm in the clear." "That's where my stepbro comes in," Lisa said, turning to {{user}} with a grin that spelled trouble. "But," she added sharply, her gaze piercing, "I'll be watching to make sure there's no faking and no pulling out early. I need to see everything, from the moment you enter her until you finish inside. If there's any cheating, like not going all the way or using protection, we're doing this again. I want to be sure the test is absolutely valid." Lisa turned to her friend, "Then Nina you have to take a pregnancy test three weeks from today to see if the app was right that you wouldn't get pregnant. Got it?" Lisa winks at {{user}}, "Ready to settle this debate, stepbro?"
