‘You really think I couldn’t seduce your boyfriend into sucking me off?’ my twin brother Jack teased, his voice dripping with that cocky edge he always has.

I rolled my eyes, trying to play it cool. ‘No way. Tyler loves me too much to fall for that.’

Jack raised an eyebrow, smirking. ‘Oh yeah? What’s that hesitation in your voice?’

I glared at him, my fake confidence cracking. He could always read me like an open book. ‘I mean… he’d know it’s you,’ I said, but my words lacked conviction. Jack and I are identical: blonde, tall, blue-eyed, with matching abs, broad chests, and toned arms from our endless competitions. We’re not bodybuilders, too busy for that, but we’re both in good shape. And yeah, I’ll admit it, the thought of Tyler with Jack, my mirror image, stirred something in me. My dick twitched at the idea, a twisted fantasy of watching Tyler with… well, me, but not me. What the hell is wrong with me?

‘How sure are you?’ Jack pressed, his smirk growing.

I opened my mouth, but nothing came out. I wasn’t sure. But I couldn’t let Jack win this stupid mind game. ‘Fine,’ I snapped. ‘Go ahead. Pretend to be me.’

He grinned. ‘If you say so.’

A few days later, me, my boyfriend Tyler, Jack, and our parents were at their house, chatting over dinner. I excused myself, mumbling about needing the bathroom, and slipped into Jack’s room. Moments later, he followed with some lame excuse. We swapped clothes: down to our underwear, because yeah, Tyler would notice if the briefs weren’t mine.

We’ve seen each other naked plenty growing up, both 25 now, Tyler a year younger. I tried not to stare at Jack’s body—my body, essentially—while pulling on his black hoodie and pants. He took my gray sweatpants and white tee, smirking the whole time. He’s straight, so he didn’t seem fazed. Me? I was fighting a hard-on.

Back in the kitchen, I sat down first, keeping my mouth shut to avoid blowing our little experiment. ‘What’d you go to the bedroom for?’ Mom asked, eyeing me.

‘Uh… had to check something on the servers,’ I mumbled, banking on Jack’s IT job to cover me. They didn’t press further, thankfully. Jack sauntered in a minute later, wearing my clothes, and slid a hand onto Tyler’s shoulder as he sat. My heart twisted with jealousy, but my dick… it twitched with something else.

Dinner wrapped up, and our parents, exhausted, headed to bed. They know I’m with Tyler, so when Jack grabbed his hand and said, ‘Come on, baby, let’s hit the sack,’ with that smug grin aimed right at me, Tyler didn’t bat an eye. He looked so happy, so in love, oblivious that the hand he held wasn’t mine. My stomach churned.

‘Sleep tight, lovebirds,’ I muttered, heading to Jack’s room, my voice bitter.

I waited five minutes, then crept to my old bedroom door, cracking it open. Tyler was curled up on Jack’s chest, his hand resting on those familiar abs, Jack’s fingers stroking his dark brown hair. It was the same affection Tyler shows me, but it wasn’t me. I wasn’t jealous anymore; just sad. Even our parents couldn’t tell us apart growing up. Why did I think Tyler could?

Jack glanced at the door, catching my eye. ‘You know… I can’t really fall asleep,’ he said, that vicious smirk flashing before softening as he looked at Tyler.

‘Why not?’ Tyler asked, his voice sweet and concerned.

‘Dunno,’ Jack said, dodging the question. ‘But you know what could help?’ He tilted Tyler’s chin up, and before I could process it, Tyler leaned in, kissing him. Jack’s eyes widened for a split second, clearly caught off guard, but he recovered fast, deepening the kiss, his hand sliding to Tyler’s neck.

My heart pounded. I wanted to barge in, rip Tyler away, but my cock was rock hard, betraying me. Tyler broke the kiss, sliding down, his hands rubbing Jack’s abs through my shirt. ‘Have you been working out more?’ he murmured, voice low and seductive.

My jaw clenched. Did he mean that? I dearly hope he didn’t. Jack chuckled, ‘Maybe,’ as he caressed Tyler’s cheek. Then he tugged down my briefs, his briefs now, revealing his 8-inch cock, hard as hell despite him being ‘straight.’ My hand moved to my own dick, rubbing through Jack’s jeans, caught in the taboo of it all.

If Tyler knew, he’d be heartbroken. He’s loyal, loving, and here I was, using him for a bet I knew I’d lose. Did I want this? Guilt gnawed at me, but I couldn’t stop watching. Tyler’s lips met Jack’s cock, his earthy eyes locked on him. Jack moaned, loud enough for me to hear, rubbing it in. That was the deal: if Tyler noticed, I’d know he loved me enough to see through the disguise. If not, Jack got a free blowjob.

‘Quiet,’ Tyler scolded, pulling back. ‘Your parents might hear!’

Jack grinned. ‘Don’t worry. They’re so knocked out on sleeping pills, a meteor wouldn’t wake them.’

Tyler didn’t respond, just went back to sucking, taking more than half this time. I couldn’t hold back anymore. I unzipped Jack’s jeans, freeing my own leaking cock, stroking to the sight of my boyfriend with my twin. Tyler mumbled something, mouth full, then pulled back. ‘Fuck… I can taste your precum,’ he said, and Jack pushed his head down again, eager.

Straight my ass. Tyler’s head bobbed faster, and I matched his rhythm, stroking myself. Jack groaned, holding Tyler’s head as he came, their eyes locked. Tyler swallowed every drop. I bit my lip to stifle a moan, my own release splattering the door with my seed.

Tyler climbed up, kissing Jack again, their makeout session lingering too long for my liking. Post-nut clarity hit hard. Now I was just angry. Jack was enjoying the kissing too much, not that he could pull back without risking blowing the ruse. Eventually, they settled down, Tyler’s head back on Jack’s chest, both drifting off in just a t-shirt and briefs.

I stood there, door barely open, torn between rage, shame, and just... being horny. What had I done?

I felt dirtier than ever. I’d never felt this low. At 5 a.m., Jack slipped into his room, handing me my clothes from yesterday. I couldn’t meet his eyes, my anger radiating like heat. I wasn’t pissed at him or Tyler. I was furious with myself for orchestrating this, for enjoying it like some sick freak.

‘Hey, a deal’s a deal,’ Jack said, his voice flat, no smirk or mockery. Just serious.

‘Yeah, I know,’ I sighed, slipping back into my gray sweatpants and white tee.

‘I won’t say anything.’

‘Thanks,’ I replied, and we left it at that.

I crept back to my room and slid into bed. Tyler stirred, his voice groggy. ‘Where’d you go?’

‘Bathroom,’ I mumbled, leaning down to kiss him, pulling him close. My arms wrapped around him tighter than ever, fear clawing at me. If he ever found out, I’d lose him. The thought made my chest ache.

‘Hey, are you okay?’ he asked, his voice soft as I spooned him from behind.

‘Yeah, I’m fine,’ I lied, kissing his neck. ‘I love you.’

‘I love you too,’ he murmured, already drifting back to sleep.

I didn’t. I lay there, eyes burning, unable to sleep, tormented by what I’d done.
