thirza blessing us with a filthy ask today…
18+ MDNI
just a reminder that you are responsible for the media you consume! if you don’t like it, DON’T FUCKING READ IT! anyways bear🐻 presents..
cw: PERIOD SEX! STEPCEST! fem!reader, dom!sam, coercion kinda so slight dub-con, creampie, oral (fem receiving), cum-eating.
“cmon, lemme help! i read it in an article once.”
you roll your eyes as your step-brother continues to pester you about trying to help with your period cramps. sam sits next to you on your bed while you lie on your back, clearly struggling with your ailments.
“sam i’m not going to fuck you just because you think it’ll help with my cramps.”
you huff out in frustration at his naïve horniness, knowing he’s just trying to get inside you. despite this, he persists.
“i know it’ll help! you’ll enjoy it too..”
“will not! it’ll be all wet and messy- not to mention gross! we’d have to lay a towel down.”
sam groans out and throws his head back, obviously annoyed with your refusal to his lust-filled proposal.
“oh please, it’s not like the sex we usually have isn’t messy already.”
your jaw drops at his disgusting (but true) statement, trying to deny that the two of you have had sex before. he’s your step-brother after all!
“n-no! i don’t know what you’re talking about.”
sam chuckles at your half-witted attempt of a lie while you try and avert your gaze from the growing bulge in his jeans.
“i think you do, sweetie. i know you haven’t forgotten about the other night..”
his dirty whispers fill your head up with images of your mouth around sam’s cock, his hands in your hair as he face fucks you rough. the night ended with your mascara smeared and your swollen lips covered in your step-brother’s milky seed.
while you were lost in thought, sam slipped next to you, his warm breath hitting your ear and leaving you flushed.
“now you remember, don’t you? cmon baby, let your big brother make you feel better.”
only a few minutes later were you bent over on all fours, sam’s thick cock ramming into you from behind. the blood spilling from your entrance served as lube for him, making each thrust let out a wet squelching noise.
he pounded into you hard and rough, leaving no room for the ‘relief’ he promised. the tip of sam’s cock kissed your cervix and forced its way into you, causing you to let out squeals of pain and pleasure.
sam’s hand was placed where your ass met your lower back, pushing you back and forth on his cock to help him thrust inside you. his other hand was tangled in your hair, using it as a handle for him.
“sweet jesus. look at you taking your brother’s cock so well. my cock looks so good covered in your blood, baby.”
you let out whimpers of protest in response, seemingly begging him to slow down or be a little more gentle, but you’re only met with maniacal chuckles in response.
sam’s hand weaves out of your hair to hold the back of your head, pushing it down into the mattress and effectively silencing you so his groans and smacking skin are the sounds left in the bedroom.
with every thrust into you, your step-brother’s heavy balls smack your sensitive clit, sending shivers through your fucked-out body. looking down at the bloody mess only turned sam on more, leaving him staring down at his cock slamming in and out of your tight cunt. the sight makes his balls tighten and his cock throb, bringing him closer and closer to his peak.
“holy fuck i’m gonna cum in this tight pussy.”
sam moans out loud and slaps your ass, marking his territory. he gives you three or four hard thrusts and spills his load into you in thick ropes of cum, leaving you spent beneath him without an orgasm yet.
before your disappointment can fulling fester, sam is pulling out of your cunt and bending down to face your pussy. he places both hands on your ass cheeks and dives face first into your cunt, slurping and sucking out his own cum.
you’re left speechless, only able to let out wanton moans and squeals of absolute bliss as your step-brother eats you out like a man starved. with each flick and touch of his blood-covered tongue you’re pulled closer to the edge of your orgasm.
“sammy i’m gonna cum! oh my god-”
sam’s hands grip your ass harder and your toes curl as your orgasm comes over you in a large wave, leaving you shaking and spasming against his tongue. sam continues to slurp and lick his way through your climax till you’re completely slumped against the mattress below you.
while you’re trying to catch your breath, huffing and puffing on all fours, sam stands up and wipes his blood and cum covered mouth with the back of his hand.
“so are those cramps gone yet?”
