The roar of the shower head still echoed faintly in my ears as I reached for the fluffy towel, a wave of heat washing over me even after the water had stopped. Then came the gasp. It wasn’t the startled yelp of someone catching you off guard, but something deeper, laced with shock. I looked up, heart skipping a beat, to find Teresa standing there in the hallway, duffel bags piled at her feet like colorful obstacles.

Her mouth hung slightly open, eyes fixated on me with an intensity that made my stomach tighten. It was one thing for Mom or Dad to catch me grabbing a towel after a shower – they’d probably just grunt something about modesty – but Teresa...she wasn’t known for her polite aversions. My naked body felt suddenly exposed .“Hello sis,” I managed, hoping my voice didn’t crack as much as it sounded in my head. “What brings you home?”

For a beat, she just stared – really stared. Her gaze bounced from my bare chest down to my exposed cock and then back up again, lingering on my face for an uncomfortably long moment. She looked like she’d swallowed a lemon whole, and her cheeks were flushed pink. Finally, she managed a strangled statement, “Ethan, dammit, why don’t you shut the door? What if mom or dad saw you?”

“Mom and dad are on vacation in Mexico,” I told her gesturing vaguely with my hand to emphasize my point. “And will not be back until next Saturday.” The last bit was clipped, a touch defensive. I’d assumed – foolishly- that being home alone for the week meant just me and maybe the occasional pizza delivery guy.

“I thought I would be all alone for the week,” I added, feeling suddenly self-conscious about the way my chest puffed out with every breath. “Didn’t know you would be visiting.”

She huffed, a puff of air escaping her nostrils. Looking me over one more time,“Well,” she muttered, starting to drag one of her duffel bags down the hallway, “I will put my things in my old bedroom.” She disappeared down the hallway and seconds later I heard the unmistakable slam of her bedroom door.

It was so quiet after that, even the faint dripping from the shower faucet seemed amplified. For a moment, I just stood there, towel clenched between my hands, feeling absurdly exposed. The air felt charged with something unspoken, leaving me both uneasy and inexplicably excited. What the hell had just happened? Was she annoyed? Embarrassed for me? Or was there something else in those startled eyes of hers when they met mine?

Teresa stood with her back pressed against the door, a sigh escaping her lips like smoke from a smoldering ember. The weight of the day – the brutal argument with Mark, the sting of his betrayal, the crushing realization that she was alone – threatened to pull her under. Eight months ago, they’d found out she couldn’t have children, and it had been downhill ever since. The spark in their marriage had died, replaced by a chilling indifference. Two days ago, she’d walked into their bedroom to find him tangled with another woman, his face buried deep in her blonde hair.

It felt like someone had ripped the heart out of her chest and stomped on it for good measure. She’d packed a suitcase, grabbed the essentials from their closet, and stormed out without looking back. A quick call to Mom – who was blissfully ignorant, as usual – confirmed she could crash at home until she figured things out.

She hadn’t expected the house to be empty. However, the thought of finding her little brother, Ethan, standing naked in the bathroom had felt like a punch to the gut. It was so…unexpectedly hot. Her gaze lingered on his lean frame and sculpted muscles – all hard lines and sun-kissed skin – before she’d practically bolted into her room.

She stripped bare with the door closed behind her and laid down on her bed. Teresa let out a low moan as the memory of that image flooded back. It wasn’t just his nakedness that ignited something deep within her. It was the way he’d stood there, so nonchalant about being caught in his birthday suit. The easy confidence of it all, and how those damn eyes – usually full of youthful mischief – had held such a captivating intensity.

Maybe she should have locked the door.

Maybe her ex shouldn’t have been the sort of coward who went behind her back rather than just breaking up with her outright. Obviously he didn’t want their mutual friends to think he was the bad guy who ended their marriage because she couldn’t have kids. Now he was going to be the douche who cheated on her in their own bed, and she had the pics to prove it.

Her husband had always been a bit insecure about himself, and while she had largely thought it cute, she couldn’t help but wish he would have been more self-assured. Sure he was disappointed that they couldn’t have kids, but he also suspected that she would use the fact that she couldn’t get pregnant to cheat on him with low risk of discovery. The irony of their current circumstances wasn’t lost on her.

He hadn’t had the confidence in himself and their relationship to know that she would never to such a thing. That was a big difference between him and her brother- her brother always seemed to do what he wanted regardless of whether anyone would judge him for it. That sort of confidence was rare, and in some ways she envied him for it. At the same time, he wasn’t arrogant to the point of being an asshole. He gave off the aura of someone who didn’t need to prove himself because he knew he was enough.

It sucked that they were related… Honestly, she would kill to have a guy like that in her life. She felt really dirty for thinking so, but she couldn’t help but admit that his body wasn’t bad either. Quite the opposite. She couldn’t help just envision him parting a woman’s legs and giving them a cheeky grin before making them clutch the sheets.

She sighed, getting up from the bed and digging in her bags for a pair of lingerie. It was a lacy dark green pair she had bought to surprise her husband. The panties slipped up the smooth skin of her leg to settle on her hips, while the bra was clipped behind her back, perfectly cupping her large breasts. Her image was studied in the mirror as she wondered: was she still appealing? Was part of the reason her husband had strayed that she had lost some of her youthful beauty?
 
She had forgotten the door didn't always latch properly, often drifting open just slightly. The gap between the door and the frame was wide enough that Ethan could see her as she rose from the bed and slipped into her lingerie. He knew he shouldn't be spying on his sister, but he couldn't help it. His gaze drifted from the curve of her shoulder to her breasts and then her hips. His breath hitched when she looked his way, their eyes meeting for a fleeting moment. A slight smile touched his lips before he turned away. He gave an involuntary chuckle and mumbled aloud, loud enough for her to hear, "That's a sight I will always remember."

He entered his room and shutting the door let the the towel that was wrapped around his waist drop to the floor. Ethan lay on his bed, closing his eyes as the image of his sister lingered. He knew he shouldn't be fantasizing about her, but he couldn't help himself because she was so damn hot. His hands drifted down his abdomen and settled on his hardening cock, teasing it with his fingertips.

They’d always been close, and yes, Ethan had harbored a slight crush on his big sister for as long as he could remember—never daring to say anything aloud. He didn’t want to risk making her mad, especially not after all the times she’d playfully tormented him: pinning him down on the sofa for rounds of tickling that left him breathless with laughter. He could have easily reversed those roles, pinned her down in turn, but it was more fun when she held the upper hand.

The thought brought a new heat to his cheeks and tightened his grip on his hard cock as he whispered her name.
