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.

Just like before, she was rooted to the spot like a deer in headlights. Was he… spying on her? There was no mistaking the way his eyes had travelled her body, and she could have imagined it, but she thought she saw his towel lifting slightly near his crotch. Did he get a boner from seeing her?

What he had mumbled too.. it put a hot knot in her stomach and an ache between her legs. God, it made her feel like such a pervert. He was her little brother, and she shouldn’t even consider thinking about him that way. Still. It shouldn’t be an issue if it was just all in her head, right? There wasn’t any sort of thought police or something, after all.

The two of them didn’t cross paths until later in the evening when it was time for bed. At that point, she showed up at his door in a silk slip, knocking softly before asking, “hey? Would it be okay if I slept in your bed tonight? I’m… not used to sleeping alone anymore.” There was a touch of bittersweet sadness to her tone.

This was silly. A grown woman sleeping in the same bed as her little brother because she was lonely? By all rights he was well within his own right to tell her to put on her big girl panties and take a hike.
 
He opened the door, and there she stood – his big sister – wearing a silk slip. It was agony keeping his gaze on her face, but after getting caught spying earlier, he didn’t want to disrespect her again. She seemed a little downcast. “Are you okay?” he asked, concern tugging at his voice. Then, impulsively, he added, “It’s fine, you can sleep in my bed. I have a queen-sized bed after all – plenty of room.”

He offered a small smile, though his heart pounded in his chest at the thought. Just pajama pants, usually, he reminded himself, crossing the room to his dresser for a T-shirt. Pulling it on, he walked back and slid under the covers—keeping from getting a boner took every ounce of concentration he could muster. he grabbed his tablet from the nightstand, and focused on scrolling through random YouTube videos, hoping the mindless distraction would calm the sudden heat in his cheeks.

He knew he shouldn’t be thinking of her this way. But seeing her there in that silk slip when he opened his bedroom door had been an instant turn-on. Now, however, seeing her so downcast really concerned him—she was usually more upbeat, but right now she seemed sad, and he didn’t know why. He wanted to ask her, but he also didn’t want to pry into her personal business. So, he decided to overlook it for now and try to act as normal as possible under the circumstances. “Make yourself comfortable,” he said as nonchalantly as he could.

“Thanks.”

Whew, it was a relief that he hadn’t turned her away. Regardless of any awkwardness between them, it seemed that he was still the caring brother she knew and loved.

That allowed her to put a little smile on her face as she nodded and closed the door firmly behind her. His room looked like it usually did, as though no time had passed since she too had lived in this house. It reminded her of happier times where he would ruthlessly crush her at Mario Cart, despite being younger than herself. He would laugh and tease her, but she would get him back by flirting with his friends when they called. There was even one time where he had hidden all of her bras in the ottoman in the front room, which earned him the retaliation of her cutting holes in his underwear so that his dick would be secure, but his balls would dangle though them.

She would have chuckled at that memory if she wasn’t feeling a bit somber.

Teresa slipped into the bed herself, laying there quietly on her back for a moment before turning her head to look at the back of his. “Mom didn’t tell you, did she?” There was a heavy sigh before she looked back up at the ceiling. “Rick cheated on me because I can’t…” she swallowed hard. “Because I can’t have kids. That’s why I’m back for a while.”
