A pillow to the head woke John up.
"Hey, sleepyhead, wake up."
John cracked an eye to see his twin sister, Alexis, standing over him. "Mom wants us downstairs."
He covered his eyes with an arm and mumbled, "Yeah, okay, Alex. I'll be there when I wake up."
Another pillow strike, this one to his stomach, doubled him over. "Sorry, bro, she said now."
John huffed, "Fine, I'll be right there." He threw the covers off and stretched, dressed only in his boxers.
Alex glanced down, and her eyes widened. She looked up at John and said, "You might want to chop some wood first. You don't want to give Grandma a heart attack if she sees your..."
She looked down again and back up. Then down and up again. John gave her a quizzical look.
Alex nodded, pointing downward, "You're sporting some lumber there, bro."
John looked down at his crotch, then quickly covered himself. "Oh geez, Alex. I'm sorry. I..."
Alex flushed, seeing her twin with such an obvious erection. But here he was, or rather, there it was, tenting his boxers upward. She desperately wanted to look down at his crotch. Instead, she turned and strolled to her bed with an air of nonchalance, saying, "No big deal. I know it happens to guys." She then plopped down on the bed and stared at the ceiling. "Chop, chop. Get to it.
"What? Now? With you in the room?"
"Ugh, Mom said I can't come down without you in tow. So yes, with me in the room."
Their mother had said nothing of that nature. She had simply asked Alex to wake her brother up. But seeing her brother in such a state, Alex couldn't resist.
"I... I can't. Not with you here. Can't you go to the bathroom or stand outside the door."
Alex knew she shouldn't push it but wanted to see how far she could take this. He wasn't the only one who needed to get off. But, for Alex, that would have to wait.
"I don't have to pee, and Mom would think it weird with me standing in the hall. Would you really want me to tell her what you are doing in here? Besides, you did it last night, and I was here."
John's eyes opened wide. "No, I didn't!"
Alex sat up and gave him a skeptical look. "Really? Because it sounded like you were..." She pumped her hand back and forth.
A heatwave of embarrassment passed over John's face. "No way. You can't... I don't... not with you here."
"Hey, look, bro, it's no big deal. A lot of guys do it." Alex snickered, "Maybe not as much as you do."
"I don't... not all of the time. How would you know?"
Alex laid back down and closed her legs, hoping she hadn't soaked through her panties yet. "We've shared the same room for like five years now. Our beds are what? Maybe ten feet apart? I have ears, and you are not very quiet about it."
John covered his face with his pillow. "Oh shit, Alex. I'm sorry. I thought..."
Alex shrugged. "It is what it is. So are you going to... you know?"
John buried his face farther into the pillow. How could this get any worse?
Shit! A horrible thought slammed into John's mind. He lifted the pillow slightly to peek down to his crotch. He let out a sigh of relief. Standing up, John turned sideways to Alex so she could see his profile. "Yeah, not going to happen. You kinda scared him away."
Sitting up again, Alex ran her eyes down his body, stopping at his boxers, now no longer tenting but still a nice bulge. "Bummer, dude. Better luck next time." She paused, "Kinda weird that you proudly showed your crotch to your sister."
John pulled on a pair of sweatpants and a t-shirt, then headed to the bedroom door. "Yeah. Let's not talk about this."
Alex watched him head across the hall to the bathroom. She dipped a hand into her shorts to feel her wetness. She was tempted to stay in her wet pants, especially since she was planning to go to her friend Jenn's house after breakfast. But no, she should put on a fresh pair, but she paused with a mischievous grin on her face. Jenn's brothers were cute, after all.
"Fuck it. I'm keeping them on."

Out of necessity, Alex and John share the only upper-floor bedroom of their house. After the twin's grandfather died, their grandmother found it challenging to live on her own. It was decided that it was best for her to move in with their family. This meant that, with no extra rooms in the house, Alex had to move into John's bedroom.
The attic had been converted into a living space, but the renovation was unfinished. John's bedroom and a full bathroom across the hall were finished, but a second bedroom was only framed out and never completed.
"It's only for a short while." Their father promised when the twins had complained about sharing. "Just until Aex can move into the other room."
Now eighteen, the twins were tall, fit and unashamed of their bodies. It was not uncommon that they would see each other partially or even fully naked, albeit from their backside. They no longer felt the need to leave the room to change. Each discreetly turned their back when they had to strip down to change. For them, it was just a part of sharing a room. Although they both enjoyed stealing a glance or two at their twin's naked body.
John would admire Alex's well-toned body in the mirror, which she had developed from playing volleyball, field hockey, and swimming. Activities that contributed to an ass that John could not look away from. Sometimes he was rewarded by catching her turn just enough to see some side boob. Although her tits weren't large, they stood out proud and firm from her body. John couldn't stare at them too long before his cock would stand up and take notice.
Alex was more obvious. She would frequently turn around to look at her brother from behind. He maintained his 6-foot-2 athletic physique by playing on his school's hockey, soccer, and baseball teams. Although she found his well-muscled shoulders and chest nice, like her twin, she was drawn to his ass. She enjoyed it when he bent down to put on his underwear, often giving her a glance at his long-hanging cock. She'd wait, hoping for John to look in the mirror to see her staring. Alex would look at his ass, then smile back at his face. John would just shake his head and roll his eyes.

Alex tossed and turned in her bed, unable to sleep. It had been four days since the morning wood incident. She lay still for a while, listening. It was clear that John was also restless.
"Hey!" she whispered. "You awake?
"Yeah, I can't sleep. What's up?"
"Me too." Alex paused, "I feel... pent up. If you know what I mean?"
"Uhm, no, I don't know what you mean."
Alex sighed deeply, "You know... pent up. I need to do... you know something."
"No, I don't know what you mean." John paused to think. "Like you have to go somewhere?"
"No, not that," frustration tinged her words.
They both fell silent.
Alex stared at the ceiling while she tried to find her courage. She took a deep breath. "You haven't done anything in three nights, now four."
'What do you mean?" John said cautiously.
