you shuffled your feet in front of your older sister's bedroom, knocking lightly before pushing the door open with a soft creak. your sister blearily leans up, squinting at you as you quietly make your way to the edge of her bed, clinging to your favorite plushie
"mmm... hey squirt, what's up?"
you frown, burying your face in your stuffed animal, too embarrassed to admit you had another nightmare and couldn't get back to sleep. your big sis picks up on your reluctance and raises her arm, lifting the blanket and inviting you into her bed
"come on then, kiddo. it's late..."
she trails off with a yawn as you pull yourself up into her bed, snuggling close to her as she drapes the blanket over the both of you. it's warm, and her scent surrounds you, your nerves quickly soothed by the closeness to your sibling. you feel her hand fiddling with the hem of your shirt, sliding up your back to run her nails gently across your shoulders. your back arches slightly, a small squeak escaping your lips as you sister chuckles, pulling you closer as she scratches your back
you sigh at her touch, her warmth, her smell, and you bring your thumb up to your lips for comfort. your mom says you're too old to suck on your thumb, but your sister never bullied you about it. she shifts in her sleep, giving you a kiss on the top of your head as she settles back onto her pillows
"y'know sis... I'd let you nurse, if that'd make you feel better..."
you briefly stiffen at her quiet words, glancing up at her. you've only done it once before, when a particularly bad nightmare had you panicking, and the two of you never mentioned it since. your sister shifts, leaning up slightly to pull her shirt up over her boobs, letting the soft, perky mounds free. you stare at her puffy nipples, lips tingling at the thought of getting to nurse on them again
you feel a hand on the back of your head, a gentle pressure guiding your face to her exposed chest, her nipple poking your cheek before you shyly open your mouth and take it in. instantly you feel soothed, a balm on your soul as peace floods your mind. you hear your sister sigh, her hand lightly scratching the back of your head as you settle comfortably against her. already you feel yourself getting drowsy, surrounded by your sister, her warmth, her weight, her smell and her taste all curling around your heart
your sister starts to hum a melody, her chest rumbling as you nurse from her soft nipple. you finally drift off to a gentle sleep, and the last thing you hear is your sister mumbling how much she loves her baby sister...
