truly, honestly, from the bottom of your very heart — you didn’t mean to get stuck underneath the bed with your lower half sticking out like the most predictable homemade porno in history.
but, alas, you did.
you were stuck, and as embarrassing as it was to have another person see you like this, you needed help.
trying to reach for something underneath your bed was clearly the wrong choice. fingers stretching, eyebrows furrowed as you extended your arm as much as it could go. “..come.. on..!” you sighed in frustration, laying your head down and accepting your fate before the door creaked open.
“y/n? are you alright? i heard the bed creak—.”
sonny couldn’t finish his sentence, freezing at your doorway. “sonny! that’s you, isnt it?” his eyes raked over your poor, helpless little body. his breathing became ragged, licking his lips.
“oh.” was this.. a dream? his adorable little brother, the boy who invades his dreams every night, sprawled out and bent over for him? the blonde gulped, his body feeling warm. wearing those slutty little shorts you insisted on, you barely left anything to imagination for the poor man, the slim fabric showing a perfect outline of your ass. so innocent — so slutty.
clearing his throat, the eldest spoke up. “um, what happened, little bro..?” sonny tried to speak as innocently as he could. he started to move a bit closer, hovering over you eerily quiet.
you looked so small like this.. bent over on the floor, ass in the air. he knew that his stature compared to yours displayed a significant height difference, but this made his head spin. “i-i was stupid, tried to reach for something that fell behind my bed, but ended up stuck in this thing. i can’t seem to pull myself out, it’s too tight. do you think you could help?”
your room was met with an uncomfortable silence.
thoughts ran through sonnys head. “was this.. okay to do?” his inner consciousness fought relentlessly, eyes staring at the door then back at you. he shouldn’t— he couldn’t! you were his little brother, and sure, even if you were older now, that didn’t excuse him being a pervert! he should just help you out and excuse himself to his room like he always does, right? yknow, the right thing an older brother would do?
the breaking point, however, was when you had shimmied your hips, trying to find a position that was less painful on your knees. your shorts had angled themselves in a way that sonny had a full view of your dick, peeking through the fabric, small and innocent and inviting.
he needed to have you. now.
it felt like forever had passed, until you cleared your throat. “big bro? i asked if you could—“ your sentence was cut off by the harsh slap on your ass, emitting a surprised yelp from yourself as sonny sighed. yea, this was obviously the correct choice. the skin was already reddening from his rough hand, making you wince in discomfort.
“ive always wanted to do that.” his laugh was shaky, smiling to himself as his palm began to sting from the impact. his heart felt as if it would burst in his poor little chest, letting his other hand slap the other cheek. “ow!” you wailed this time, head bumping against the bottom of the mattress as you tried to instinctively get away. but you couldn’t — you were trapped in sonny’s grasp. sonny was strong. he had to be, given his line of work and title, but you never really learned the true extent of it until today. the officer couldn’t help himself, fingers grabbing onto the waistband of your shorts and pulling everything off, your bottom half exposed.
“god, look at you, little bro. your body is so perfect. we’re you waiting for this the entire time?” you stood silent, speechless at what was unfolding. even if you had shook your head ‘no’, sonny wouldn’t care, quickly giving into his own perverse desires. of course you did this on purpose — why wouldn’t you? it was too perfect of a moment not to be planned out beforehand. the slutty little outfit, your parents not being home until tomorrow, and sonny having the weekend off. how considerate of you, to think of your creepy older brother like this. your ass looked so inviting, the blondes mouth started to water. his intrusive thoughts won, shuffling closer until his mouth was mere centimeters away from your little hole.
“wait, s-sonny, you can’t!” you tried to squirm away, sonnys hands gripping your thighs to keep you in place; not that he needed much help, with the mattress sandwiching you. moaning, your toes curled in pleasure as your brother began making out with your asshole, groaning and huffing behind you. it felt beyond dirty, your sounds only spurring him further, tongue delving past the tight rim of muscle as he closed his eyes in pure bliss. it was every perverts dream, after all.
his skilled tongue slurped obscenely in your hole, your cock pitifully leaking tiny spurts of precum from how dirty this all was. it felt humiliating. having your ass eaten as a guy was one of the least things you’d expected to ever happen to you. sonnys face was flushed, eating as if he was a starved man, lips and chin glossy with spit. everytime the man pulled back, he just delved right back in, your resolve stripping away with every flick of his tongue. it was so sloppy, some of his saliva even dripped down your taint, a trail dripping onto the floor. the older man groaned, furiously pumping.. was that his cock? fucking into his hand, sonny gave one last smooch to your hole, pulling away with a sigh. your cock twitched, whining at the loss of touch as your hole fluttered around nothing. you were aching, core nearly on fire with how badly you needed him — someone, anything to fill you up, as shameful as it made you feel.
for better or for good, the blonde was impatient. smirking, sonny popped open a small bottle of lube, the click making your heart drop. was he..?
“b-big bro, this isn’t funny anymore, okay..? just help me out of here, please?” you spoke up, voice shaky without a single threat in them. i mean, what could you do? you were in sonnys hands now, and no one was coming to help you for hours, lower half exposed and ready for the claim. sonny hummed in response, a hand tenderly caressing your red skin, thumb cheekily slipping into your hole.
“of course ill help you out, y/n. i never said i wouldnt.” sighing in relief, you wiggled your ass, trying to squirm and get yourself out. unfortunately, in sonnys twisted mind, it looked as if you were teasing him even more. he took his thumb out of your ass, instead teasing the gaping hole with the tip of his cock. practically growling, his hand spanked the soft skin of your behind, shuffling to get even closer to you.
fucking slut. “..i didn’t say id let you out right now, though. be good for me, won’t you?” you didn’t even have time to process sonnys words before he slipped inside you, gripping your ass as he let out a loud moan.
“fuck, oh god..” the officer cursed under his breath, eyes closed from how blissful your walls were clenching around him. you sobbed softly, at least thankful that being stuck here meant sonny didn’t have to see how pathetic you looked — not like it would deter him from his goal or anything. “you’re so tight, i can — hah! barely move, fuck!”
the squelch of your lubed ass sucking his cock in made you cringe, sonny losing himself in the erotica of it all. taking off his shirt, he pulled out, granting you a moment of relief before he slammed back in again. “s-sonny!” you tried to get up again, hitting your head hard against the metal frame of the mattress, but sonny didn’t care. he couldn’t find it in himself to give a damn. you were so smaller so tight, so pliant in his hands. the blonde showed no mercy, pistoning into your poor body with little grunts of appreciation.
full. you felt so, so full. it wasn’t a surprise sonny had a big cock to match his big stature, but god, you swore you could feel him in your tummy as he abused your little hole. before you knew it, you were moaning now, desperate little whines of pleasure as sonny rammed in that spot that made you see stars for the first time in your life. “b-big bro.. slow.. nnh..!” sonny chuckled, spanking you again to add to the other countless times today, cock twitching inside of you. the wet plap of skin against skin did nothing to help your brain, slowly turning into mush with every stir of the blondes dick.
“you like this, don’t you, y/n? getting fucked like a girl? yea?” you whined loudly, the coil in your stomach only growing tighter and tighter because of sonnys filthy words. you were positive you wouldn’t be able to sit after this, from the way the older man fucked you as if he wanted to make your insides remember his shape. drooling, your legs were wide open, wanting more of the sickly pleasure he was drowning you in. “sonny, o-onii, i cant—!”
god, maybe sonny should’ve pulled you out from underneath this mattress. he licked his lips, so badly wanting to shove his tongue in your mouth, trap you in a mating press like you deserve. hissing from how tight you clenched around him, sonny extended his hand to squeeze your cock, relishing in the loud cry you let out. “come on then, little bro! i know you can do it. cum for me.” his voice dropped low, his pace unforgiving on your poor little body as you came with another yell, thick seed pooling below. seeing you cum all because of him was enough to send the pervert into his own frenzy, quickly cumming after you. his load spilled deep inside, sighing in relief as you groaned.
your body fucking ached, bruised and sore everywhere. you didn’t even have the strength to keep your knees up, only held by sonnys strong hands as he coo’ed at your pitiful state. don’t worry, little one — your big brother would take care of you all weekend long.
“ill let you out now, okay? then, we can go for round two.”
