❕cw: pseudo-incest, piss kink, menstruation, mentions of p n v sex
“dragging me alone into the bathroom? gotta say, pips, that's scandalous.”
he would say no, but his eyes are trying very hard to focus on anything other than his sister unzipping her denim miniskirt and shimmying it down as she sits on the toilet. caleb knows something inside of him will inevitably snap.
the bathroom is outdated, maximalist wallpaper poorly applied and an orange hue to the vanity bulbs buzzing in the static air around them. the blue ceramic claw tub is certainly a sight to behold— well, not as much as the one in front of him.
he straightens, militant reflex kicking in to be of service to her. she spreads her legs wider and wider until the folds of her pussy are on display, a small cotton string protruding from the center.
“told ya it was gonna start today.” he smirks up at her as he crouches down, a sparkle in his eye making something in her stomach curl.
not being able to help himself, he presses a chaste kiss to her inner thigh before thumbing at her labia. she grips his bulky shoulders as if to steady herself for the procedure. long fingers begin to pull gently at the tampon, struggling when she clamps down.
a shaky ‘sorry’ whispers from above him. another tug gets the thing to come out in one fell swoop, resting wetly against his fingers. it’s a dark crimson. the flow isn't too heavy yet; he can tell just by how the string itself isn’t soiled. wrapping up the inspection, he lets the used product fall into the water below her.
no matter how many times he does this, she still blushes at the act of it all. even more so when he spreads her cunt impossibly wide, commanding her to let go. she does, obedient as always for her gege.
the stream splashes into the bowl, steady enough for him to assume she’s been needing to go for a while now. he would scold her for holding it in, but he can’t bring himself to do it when his erection strains so brutally against the front of his jeans. he’d find a way to get inside of her after the party. no question.
“good girl.” he coaxes, thumb grazing her clit playfully. squirming with surprise, droplets of urine spatter onto the seat.
he huffs out a chuckle as he gathers toilet tissue to wipe her with. front to back, then using a feminine wipe he kept handy. makes sure to remove any prior staining or dried blood. he can still feel the softness of the jojoba oil he applied to the dark curls that adorn her mons pubis and it makes his cock twitch.
inside. he needed to be inside someway, somehow.
reaching into his pocket, he digs out a new tampon for her. before he can hand it to her, small fingers wrap like a death grip around his wrist. he gives an expectant look with a cocked eyebrow. patiently waiting for the words he already knows she’ll say.
by the grace of god, he spares her the theatrics of laughing at her apparent desperation. caleb preps the applicator with practice, lining it up to her entrance, then pushing upward to insert. the stretch of dry cotton paired with an abdominal cramp makes her wince. still, he finishes gracefully like the dutiful brother he is.
a sigh of relief releases from her lungs.
her index points at the obvious tent in his pants.
