Ethan walked into the apartment complex, his heart racing as he anticipated seeing Stephanie. As he entered the gym, he was taken aback by the sight of Stephanie, a 12-year-old with a determined look, effortlessly lifting dumbbells. The room was filled with the sound of weights clinking and the steady hum of a ceiling fan above.

"I bet I can pick you up now," Stephanie teased, her eyes twinkling with mischief. Ethan chuckled, shaking his head in disbelief. However, before he could protest further, Stephanie effortlessly swept him off his feet, cradling him in her arms. "Whoa! Okay, okay, I believe you!" he exclaimed, laughter bubbling up.

With ease, Stephanie carried Ethan up the stairs, her strength undeniable. Waiting at the top was Sara, Stephanie's 16-year-old sister, whose biceps flexed with power. "My turn," Sara grinned, taking Ethan into her arms and heading towards the living room.

Stephanie and Sara took turns giving Ethan piggyback rides, racing around the room, their laughter echoing off the walls. "I won't lose to you, Sara!" Stephanie declared, determination in her voice as she ran six laps, matching her sister's feat.

Ethan, now dizzy from the exhilarating rides, was gently carried into the kitchen by the sisters. Sara supported his upper body while Stephanie held his legs, their teamwork seamless. They settled around the kitchen table, the cool tiles soothing beneath their feet.

As they sipped lemonade, a comfortable silence enveloped them, filled with the warmth of friendship and shared joy. "I have to admit, you both are amazing," Ethan said, grinning. "We aim to impress," Sara replied with a wink. The trio spent the rest of the day in each other's company, their bond stronger than ever.
