Yet, despite being able to keep up with her, Shawn didn't pass her. Instead, he chose to stay slightly behind her, watching her toned ass cheeks jiggle with each step. Her shorts rode up with her movements, revealing the lower curve of her buttocks.
It didn't help that her long, pale legs were on full display either. The way her thigh muscles flexed and relaxed with each stride was hypnotizing to watch. Combined with the sweat glistening on her bare lower back and shoulders, Shawn found himself getting distracted.
And the distraction was becoming apparent. His shorts were starting to feel tighter around his crotch area, and he was grateful for the loose fit that helped conceal his growing problem.
Meanwhile, Angela didn't seem to notice anything as she continued to push herself. She was enjoying the burn in her muscles and the feeling of the wind rushing past her.
Not to mention, having her brother trailing behind her like a lost puppy was doing wonders for her ego. She had always been competitive, and beating others—even her own family members—gave her a sense of satisfaction that nothing else could.
For Shawn, the morning run was becoming an exercise in self-control. He kept his focus on Angela's ass and legs while trying to maintain a neutral expression on his face.
"Try to keep up!" Angela called back over her shoulder, not slowing down one bit. She glanced back and saw Shawn right behind her. "Is that all you've got, little brother? I expected more from you."
"You're the one who started running faster without any warning. Otherwise, I would've been ahead of you by now," Shawn retorted, forcing himself to look away from her body and focus on the path ahead.
"Excuses, excuses. Just admit that I'm faster than you."
"Never."
Soon, they reached the park at the edge of their neighborhood, and Angela slowed down to a jog, then to a walk. She placed her hands on her hips and bent forward, catching her breath. Sweat dripped from her forehead onto the ground.
Shawn also slowed down, though he wasn't breathing as heavily as she was. He stood beside her, pretending to be more winded than he actually was to keep up appearances.
"It's been a while since I ran that fast," Angela said between breaths, wiping sweat from her brow with the back of her hand. "You've definitely improved. Not as much as me, of course, but still."
"What do you mean, 'not as much as you'? I was right behind you the entire time." Shawn rolled his eyes at her and nudged her playfully. "If I really tried, I could've left you in the dust."
"Yeah, right." Angela straightened up and stretched her arms over her head. "If you could've left me in the dust, you would've done it already. Face it, little brother. I'm still faster than you."
As Angela stretched, her sports bra pulled tighter against her chest, emphasizing the fullness of her breasts. The fabric hugged her curves, leaving little to the imagination.
Noticing where Shawn's gaze had landed, Angela snapped her fingers in front of his face. "Eyes up here, perv. What are you looking at?"
"Nothing. Just admiring the view," Shawn replied with a smirk, not bothering to deny it. "It's not my fault that you're so eye-catching."
Angela shook her head at him, though a small smile played on her lips. "You're such a shameless little brother, aren't you? Now come on. Let's get some water before heading back."
She led the way to a nearby drinking faucet, bending over to drink from the spout. Again, her shorts rode up, exposing more of her ass cheeks this time.
Shawn stood behind her, watching as the water dripped down her chin and onto her chest. The droplets traced paths between her breasts, disappearing into the valley between them.
He found himself wondering what it would be like to be the one touching her instead of just watching from afar. To run his hands over her smooth skin and feel the warmth radiating from her body.
"Are you just going to stand there and stare, or are you going to get some water too?" Angela straightened up and turned to face him, wiping her mouth with the back of her hand.
"Why can't I do both?" Shawn countered with a grin as he stepped forward to drink from the faucet himself.
The cool water helped quench his thirst, but it did little to cool the fire burning within him. Especially with Angela standing so close to him, her body heat and the scent of her sweat filling his senses.
After Shawn finished drinking, they started jogging back home. The sun had climbed higher in the sky, and the temperature had risen with it. The comfortable coolness of the early morning was slowly disappearing.
As they approached their house, Angela spoke up. "Let's go to my room when we get back. We need to stretch properly, or we'll be sore later."
"Sounds like a plan. I could use a good stretch after that run," Shawn agreed, already imagining what kind of stretches he might get to see.
Once inside, they headed upstairs to Angela's room. It was spacious and tidy, with a queen-sized bed in the center and a desk in one corner. The walls were painted a soft beige, and the floor was covered with a plush gray carpet.
Unlike most girls her age, Angela didn't have much decoration or personal items on display. There were no posters on the walls, no pictures of celebrities or cute animals on her desk, and no clothes thrown about.
The only things that stood out were a few books stacked neatly on her nightstand and a framed certificate from her university hanging proudly above her desk.
"Alright, let's start with some basic stretches." Angela positioned herself in the middle of the room and began with a simple forward bend, reaching for her toes.
Following her lead, Shawn stood beside her and copied her movements. He was close enough to smell her sweat mixed with a faint scent of lavender from the diffuser on her nightstand.
They moved through a series of stretches in comfortable silence, focusing on their breathing and the sensations in their muscles. Angela guided him through each pose; her instructions were always simple and clear.
