Unforgettable: Tempted to sin by my best friend's brother

Some connections are too powerful to ignore… and some lovers are simply unforgettable.

Connor and Logan have been best friends since kindergarten. Now in their third year of university, sharing an apartment feels as natural as breathing—easy, comfortable, and safe. Until the day Connor comes home and finds a tall, broad-shouldered stranger laughing with Logan in their living room.

The stranger turns around.

It’s Shaun—Logan’s younger brother, the kid who moved away years ago and barely feels like a memory anymore. Only now he’s grown, confident, and devastatingly handsome. And the looks he keeps giving Connor? They definitely mean something.

When Shaun comes out, Connor realizes the truth: the sparks between them are real—and dangerous. Logan has no idea Connor is gay, and definitely no idea what’s building between his best friend and his brother. One weekend under the same roof is all it takes for temptation to win, and for lines to be crossed that can’t be uncrossed.

Because some feelings don’t fade. Some connections don’t break. And some mistakes are anything but forgettable.

It was grey, overcast, and pissing down outside. Another rainy January on the Pacific Northwest in the dreary seaside metropolis of Seattle. I’d honestly prefer it to snow here instead.

At least, that would brighten things up a bit.

But I was used to it, having lived here all my life. I had been looking forward to getting away to somewhere like California to study, but the decision to stay in my hometown to attend university was made without question because I wanted to stay close to my best friend, Logan.

Logan and I had been thick as thieves since kindergarten when he’d pushed me over in the playground, taken off with my backpack, and encouraged me to chase him.

When I caught him, he pummeled me.

Best friends for life.

Logan had only been extended an invitation to attend the University of Washington. So now, here we were, years later, renting an apartment together near campus—third year running.

Living at home with our parents had been out of the question. Logan had insisted he wanted freedom to explore the sultry side of campus life. I agreed with him in principle.

So far, I hadn’t partaken of that perk; instead, I had been annoyingly bearing witness to Logan bringing home one girl after another. I’d taken to wearing headphones and listening to music to block out the sounds of his groaning and grunting, travelling through our thin walls.

Don’t get me started on the sounds the girls made.

My man, Logan, must be hung or at least good at what he was doing. None of them stuck around, though … until recently. My best friend had fallen in love … and it was nauseating.

I smiled as I scrolled through the streaming guide, looking for a movie to watch. I was honestly happy for him. He deserved someone who would put up with him. I liked his girlfriend, except when she tried to set me up on a blind date with one of her friends. I’d nearly run out of excuses.

I had a girlfriend for most of my years at high school, but broke things off with Mandy right after our senior prom. I didn’t want any entanglements, and honestly, I hadn’t been fair with her.

It had been easy to date the girls, who flocked around my good looks, to keep suspicions at bay. Blond hair and blue eyes were my weapons, but I had secrets not even Logan knew.

I hadn’t meant to keep it to myself, my gradual reckoning with the reality that I wasn’t interested in the girls I walked with, hand in hand, down the school hallways, my entire teenage life. Now that so much time had passed, I felt awkward bringing it up.

I knew I had to tell Logan. I wanted to start dating and bring home the guys I got messy with in the dark corners of the university dorms and the student union pub washroom.

I ran my hand through my hair and shut off the television. It was Thursday evening, my day off, and I really should be studying. My mood was in the dumpster, though.

Needing to move to shake it off, I decided to go for a run. When I came back to the apartment, Logan was standing in the living room facing someone I could only see the back of.

The unknown visitor’s hair was dark and sleek above his broad shoulders; he was tall and muscular, and he had a lush ass that I could get lost in, face-first, for hours.

I cleared my throat to get their attention.

I took a step back when they turned to face me.

Oh, Jeezus.

It was Logan’s younger brother, Shaun, who had made my cock take notice. A rush of heat flooded my face, leaving me parched. I never would have recognized him from the back. He lived exclusively with his dad in Portland, but out of the blue started at UW in Seattle this semester.

Logan and I hadn’t seen Shaun around yet. We were already three weeks into classes, but Logan and Shaun weren’t close because Shaun moved away when he was ten. After his first ten years, I’d only seen Shaun a handful of times during the odd summer vacation.

Understatement—he’d changed.

While Shaun had grown into this beast of a man, I had missed out entirely.

Logan had been surprised to hear his brother was coming back to our corner of the rainforest. For some reason, Shaun had decided to move in with his and Logan’s mom in Seattle and switch universities. Something had gone down between Shaun and his dad. Not sure what.

Even Logan didn’t know.

“Hey, Connor, long time, no see.” Shaun reached out his hand to me.

“Yeah … yeah … it’s been a while.” The pressure of his firm grip on my hand went straight to my dick, and my mind buzzed through all sorts of scenarios that involved him riding my cock.

Stop it.

Focus, Connor.

I crossed my arms. “You settling in all right at school?”

“Finding my way around.”

I almost licked my lips while watching his form words. “And your mom?”

Shaun laughed. “She’s glad to have me there since Logan abandoned her.”

Logan chuckled. “I did not. I just didn’t want to subject her to my debauchery.” He smiled as Shaun gripped his shoulder and gave him a jovial shake.

“Mom says you have a girlfriend, Logan.”

“Yeah. Carly.”

I swear to God, his eyes went all swoony. My buddy was sunk.

“And you?”

It took me a second to realize Shaun was talking to me. I shook my head. “Nah, living the single life for now. I’m focused on my studies. Plenty of time to be nailed down later.”

Logan laughed. “He lives the life of a saint. Haven’t seen him with a girl since high school.”

Shaun blinked at me, and his gorgeous brow furrowed a little. His gaze lingered on me long enough that I began to feel like he was unwrapping my tightly guarded truth.

“So ….” Shaun clapped his hands. “What’s for dinner?”

“God, I can’t believe you’re staying with us for the weekend,” Logan said, surprising me. He hadn’t mentioned house guests of the brotherly kind. “You’re going to eat everything in the place.”

“Not my fault, I have good genes.”

“Yeah, of the gladiator variety.” Logan grabbed Shaun’s arm and hauled him toward the kitchen. I hung up my waterproof coat, kicked off my wet sneakers, and followed, leaving a trail of water on the floor. Thursday was pizza night, and I wanted to avoid a pineapple caper. One thing I remembered about Shaun is that he shared his brother’s gross affinity for the stuff on pizza.

Logan pulled me aside. “Hope you don’t mind. Shaun showed up at the coffee shop. I felt all brotherly and asked him over. When you walked in, I’d just asked him to stay with us.”

“You should have run it past me first.”

Mainly because having Shaun in our apartment made me want to take up tree climbing. The guy easily had four inches on me, and I wasn’t lacking in the height department.

“I know, sorry.” He grasped my bicep. “Is it all right?”

I grinned at him. “Only if I get a whole large bacon and pepperoni to myself.”

Logan clapped my shoulder. “Done.”

With the pizzas ordered, I dashed off to my room, bath towel in hand, dried my rain-soaked hair, and pulled on grey sweatpants—commando, a sweatshirt, and fuzzy socks.

It didn’t feel like I’d ever warm up.

A hot shower was in my future. One where I would be imagining Shaun pressed up against the glass of the enclosure while I fucked his ass until he called my name and came hands free.

My dick was far too eager for me to follow through, but I went to the kitchen instead, grabbed myself a beer, and joined Logan and Shaun in the living room.

The pizzas arrived thirty minutes later, while we were still looking for a movie to watch, and the entire time we were eating, Shaun’s attention kept lingering on me, then flitting away after a cheeky smile when I caught him staring. Fuck, he was beyond gorgeous.

The crinkles in the corner of his dark, brown eyes before he turned away had me shifting in my seat, begging my cock to take a goddamned break.

“How’s Dad?” Logan asked as he lifted another slice of ham and pineapple.

Shaun shrugged. “Same as always. Rigid to a fault.”

“You two argue?”

“Yeah, sort of.” Shaun nodded, then used his thumb to rub some tomato sauce off his lips. He popped his thumb into his mouth and sucked on it. His gaze connected with mine, and he smiled.

Logan was oblivious to the subtleties Shaun was throwing at me and barged ahead.

“What about?”

Shaun cleaned his fingers with a napkin. “Told him I’m gay.”

I swear, Logan and I coughed and nearly choked at the same time. Logan, because he obviously had no idea his little brother was gay. Me because … well, it seemed Shaun had been flirting with me since I walked in the door. And I hadn’t exactly shut him down with all my not-so-covert adjustments to persuade my twitching dick to heel.

Then, like the stupidest big brother ever, Logan asked, “Since when?”

I rolled my eyes. “Really, Logan?”

Logan lifted his hands and shrugged. “What?”

“People are born gay, you idiot.”

Shaun nodded. “Connor is right. Always been gay. Just got tired of hiding it.”

“And Dad was upset?”

Shaun tipped his head then shook it. “It’s not like he’s a homophobe or anything. He just needed time to think and wrap his head around it. I decided to give him his space.”

“And Mom?”

“She’s cool with it. Strict rule about not bringing guys back to the house, though.”

Logan picked a few random pineapple pieces off the bottom of the pizza box and balanced them on his latest slice. “That’ll cramp your style a bit, I’m sure.”

“Yeah ….” Shaun looked at me. “Sucks when you can’t be yourself.”

And then the lumberjack-sized fucker winked at me.

Jeezus fuck.

I almost groaned with need for him. And was lost in the rapid pounding of my heart when Logan announced, “I’m off to have a shower.”

Shaun smiled at me. “We’ll amuse ourselves while you’re gone.”

We both watched Logan go, and when the shower started up, Shaun left his seat, crossed the living room, and knelt at my feet. He brushed his hands up my thighs. “Well?”

My cock throbbed, fully tenting the front of my sweats. “Well, what? Do it.” I pushed my hand into his hair and gripped onto a thick clump so I could guide his beautiful mouth. I lifted his chin, and his sultry eyes met my gaze of absolute frenzy. “Suck my dick.”
