Sibling Rivalry

Oh. My. God.

Trish's face was burning as she turned away from the passenger side door. No. No, she so did not just watch her little brother jerk off. That didn't happen. No way. Her brother didn't have sex. He was Darry. He was her pathetic, dorky little brother that she'd grown up with. He didn't know anything about sex. He didn't think about it ever. He certainly never masturbated. And she certainly didn't feel this way after watching it.

Now entering the Denial stage. Enjoy your stay.

Exhaling slowly, Trish turned around to face the car again. Darry was still in the front seat, but his jeans were now zipped up and her shirt was shoved back into the dirty laundry bag. There. It was like nothing happened. Great. Fabulous. Super. Time to get the fuck out of there.

Opening the door, Trish slid into the passenger's seat, tossing her things into the back. She looked straight ahead out the windshield, refusing to turn or acknowledge Darry in any way. So long as she didn't see him, she'd be safe. It would be like nothing happened.

"Trish? I-"

"Shut up, dorkwad. We've got a long drive ahead of us."

She didn't need to look at him to know he was cringing at her comment. Her stomach twisted uncomfortably, both from the painful awkwardness of the situation and the thought that she'd hurt Darry's feelings.

Well maybe if he hadn't felt the need to blow a load into your tank top, you wouldn't be in this mess, would you?

Oh shut up. That didn't happen. I imagined it. Everything is fine.

Darry turned on the car as Trish fastened her seatbelt. They pealed out of the rest stop, kicking up sand and gravel in a big cloud as they went. Neither said a word. Darry focused on driving while Trish propped her head against the window, watching as the grass in the fields beside them zoomed past in hypnotic patterns. Perhaps because of the quiet, or perhaps because her mind was begging for an escape from the terrible feeling left hanging in the air, her eyelids began to sag and soon she was asleep.

---------------------

"Ungh..."

Trish's gasp shifted the thin curtains just a few inches from her face, but there was no one else close enough to hear the sound. She was sitting on top of her college trunk that she'd stuck beneath the window in her room. One arm leaned against the sill of the open window as she looked down, watching her brother struggle with the old gas lawn mower in the front yard. Her other arm snaked down over her stomach, reaching into the front of her pajama bottoms where her hand was very much occupied. The warm summer morning air was mixed with the smell of smoke from the stubborn mower and cut grass, but Trish wasn't focusing on that. Her eyes followed her brother's movements as she touched herself frantically.

The mower stalled and Darry cursed, kicking it. He paused in his fight, grabbing his discarded shirt off the driveway pavement to wipe away some of his sweat. He always tried to finish mowing the grass early in the day before the summer heat grew too suffocating, but even now it was still hot. Running a hand through his shaggy black hair, he glanced back at the house and spotted Trish staring at him from the window in her bedroom. He gave her a weird wave, surprised at seeing her watching him.

It took Trish a moment to realize he'd seen her, but once she caught on she froze. She was sitting sideways and her waist was below the level of the sill, so he obviously couldn't see what it was she was doing. She smiled back at Darry, waving with her other hand.

"Mornin', Trish..." Darry's eyebrows were still raised questioningly.

"Morning... sorry, not entirely awake yet." With an excuse given, Trish began moving her fingers again, a surprisingly large shudder running through her body. There he was, Darry, standing there talking to her while she masturbated... it made everything feel so much more intense. Her breath caught in her throat a moment, but she forced herself to at least keep some outward look of normalcy.

"Right - little miss college student thinks that now she's back for the summer she can sleep all day and leave the work to me, huh?"

Act normal, Trish... "I'd say that's about the swing of things, turd. I earned my way out of that stuff, so it's you're turn now."

"Earned it? What did you do to earn it?" Darry was just picking a fight now, but that's what they did. All siblings fought, but Trish and Darry did it for fun. It was all a game. But this time, Darry was missing out on one big factor.

"Hey, I was here all by myself before you were born. Now you're playing the only child."

"Trish, you are two years older than me. I don't think you were mowing the lawn when you were two."

"Not my fault!" She tried her best to shrug, but her control was fading. Her breathing had picked up even more and her legs were trembling as the muscles started to slowly tighten.

"Yeah, sure... lazy whore!"

"Get back to work, yard boy. Or maybe I'll just have to do something productive like drink the last of the lemonade while you're working." She laughed nervously, leaning forward to mask the way her hips had started to rock against her hand.

"You bitch!" Darry laughed, his mock horror easily seen on his face. He waved it off a moment later, shaking his head as he started to walk back to the mower. "Well, just don't switch the sugar in it for salt like you did last time. That was just plain sadistic."

"Less whining, more mowing!" Please, mow... don't know how much longer I can last...

Darry sighed and wrestled with the mower some more before the engine kicked in and he went back to pushing it back and forth across the yard. Trish watched the sun reflect off his sweat-slicked back, saw the muscles stretched over his shoulder blades pulling taught as he worked, noticed the stray strands of dark hair that stuck to his forehead...

Oh God...

Every muscle in her body simultaneously clenched as Trish let out a choked gasp, nearly falling off her trunk. Her fingers stopped as she felt her clit throbbing against them in that painfully-pleasant way it always did right after she orgasmed. After a moment she collapsed forward against the window sill, thankful that Darry had his back turned for the moment. She withdrew her hand from her pants, fingertips sticky, and decided she best have a shower before heading downstairs. She needed to wash up and to get her mind off the fact that this was the umpteenth time she'd come thinking about her younger brother...

--------------

Trish sat up with a start as she heard the car door slam. Startled and unsure for a moment where she was, she stared out the window blinking. Darry gave her a small wave as he put the gas pump into the tank valve, leaning against the car.

Right. Dreaming. Go me.

Things slowly filtered back to her as she waited for Darry to finish filling up the car. Yes, she'd caught him jerking off in the driver's seat that morning. It was awkward, but then again she supposed it was naive of her to think that Darry didn't do that sort of thing. Probably all the time, really. He was a guy after all, and considering her own past... well, she wasn't one to talk. Not that she'd exactly been talking. Maybe it wasn't so much the fact that he'd been masturbating that unsettled her as it was that she found it kinda... hot.

Well, he'd just seen you topless. Maybe he was...

No. Darry? Jerking off to thoughts of... her? Well, why not? She'd been doing it for years herself. Hell, she went through a period where she had tried to entice him as a way of getting revenge on him. He didn't seem to seriously notice how attractive he was, so she'd try to make sure he'd catch her in the hallway after her shower when she was in just a towel, in some desperate hope that he'd have to go masturbate himself. That was what she'd do afterwards, anyways. To think that on the other side of her bedroom wall, Darry was on his bed thinking about her as he touched herself was just too much for her. And to think he was doing that at the same time that she was - well, she'd always thought that would be too good to be true. But maybe... it hadn't been.

The car shifted as Darry put the pump back and stood up from his lean. He went inside, payed for the gas, and came back to start up the car in complete silence again. He was still thinking about what had happened... it wasn't something that would just go away. They pulled out of the gas station parking lot and continued on down the empty stretch of country road. It was another five minutes before Trish cleared her throat.

"Hey, Darry?"

"Y-yeah Trish?" His voice cracked nervously as he spoke and his cheeks instantly flushed with embarrassed guilt.

"I, uh... I think we might need to talk."
