Edwin drove to Derek and Casey’s apartment, eager to share his news with the two people who were most invested in his cause. He knocked on the door and Derek let him in, Casey yelling in the background about ordering sauce-less pizza for dinner.
Edwin smirked. “How’s that going?” he asked his brother.
Derek rolled his eyes, but the phone rang before he could talk about his wife’s out of wack hormones. Casey appeared in the kitchen to answer it. “Hey, Ed”, she nodded, grabbing the cordless phone.
“Casey”, he chuckled, waving back at his sister-in-law.
“You and Lizzie”, Derek started tiredly, “You guys ever play extreme Frisbee?”
Edwin shrugged, “Sometimes, why?”
“Make sure it’s not too extreme”, Derek said dryly, nodding to Casey. “I’m pretty sure that’s how she got pregnant.”
“Good to know”, Edwin rolled his eyes.
Casey had hung up the phone and made her way across the kitchen to smack the back of Derek’s head. “Don’t blame your horny urges on extreme Frisbee. Any time I run or start to sweat, you freaking pounce on me. That’s why I’m pregnant!” she insisted, rubbing the slight curve of her stomach.
Derek grinned guiltily.
“Uh, about why I’m here – before you two start humping like rabbits”, Edwin interrupted quickly, pulling a small box from his pocket. “I bought a ring.”
