puts it um.. below the this thing.. um.. if you want to read it.. it's has um.. sisters doing some.. normal sister stuff.. so.. content warning for that..
Her little sister's chest gently rose and fell with every soft, quiet breath she took.
"Fuck.. I shouldn't be doing this.."
She held her plushie tight as she laid on her side, various faint stains from the many years of feelings shared with it.
"nn.. but.. I can't.. stop.."
Her big sister shuffled quietly above her, erect cock hovering a few inches above her face, slowly being stroked while she stifled her moans. The long night of fun she had had with her friends had eventually led her to her sister's bedroom, the room faintly lit with various little night lights, the two of them engaged in a one sided sisterly activity.
She rubbed the drop of pre that left her cock, smearing it around her head to stop anything from dripping onto her little sister. Every thought in her mind was telling her all the various ways she was ruining her life, ruining her relationship with her sister, the girl she loved and was oh so close to, and yet they only served to make her throb and buck her hips the tiniest of bits.
A hand rest on the headrest of the bed, her knees on either side of her sister's shoulders, the engorged head of her cock blocking some of the view between her and her little sister's soft sleeping face. Her other hand moved from the base of her cock to the tip, in slow motions that could only faintly be heard amongst all the other noises of the night. Her little sister was a heavy sleeper, but even this was pushing it, she knew. What would she do if she woke up to this sight, saw her beloved big sister jerking off over her sweet innocent sleeping face? The question just made her throb even harder, and she nearly lost herself in the wave of pleasure that washed over her, catching another drop of pre just in time. She didn't know what compelled her to climb onto her sister's bed, but she knew what was keeping her here at least.
Suddenly, her little sister started to murr in her sleep, mumbling and rolling from her side to facing directly up. She froze instantly, hand still on her cock, twitching every few seconds in a violent throb as she hovered just a few inches from her face, but now she was looking right at her. A few minutes passed, both of them still and quiet, save for the little sister's soft breathing out through her mouth. Her big sister's cock moved down slightly, and she was able to see more of her, the head of her big sister's cock positioned just above her slightly parted lips. Slowly, she resumed her stroking, but unfortunately for her, realized too late that pausing stroking for a few minutes had built up a rather large amount of pre.
She watched in slow motion horror as a droplet formed at her tip, unable to stop her hand from stroking, unable to do anything as it grew and grew and left her tip, gliding through the air and descending below. The drop, still barely connected by a small strand of pre, landed in the small gap between her little sister's soft lips. Spreading across her sleeping tongue, she let out a soft sleepy moan, mouth acting on instinct as the slightly salty treat spread over her taste buds. Her big sister had already stopped moving, scared for her life as her cock continued to happily leak a drop every minute or so. She couldn't move, couldn't make herself, the only sign of life was her cock, twitching and throbbing in the air, leaking freely and happily filling her little sister's mouth with her pre. All the thoughts racing through her head had crescendoed and crashed, and she didn't even blink as timed continued to pass. Her cock throbbed, a drop of pre oozed out and dropped down into her little sister's mouth, who continued to only slightly stir with sleepy joy as she was blessed with yummy treat after yummy treat.
After what must've felt like an eternity for her, with her eyes glued helplessly to the happenings below her, she grabbed the base of her cock once more, and resumed stroking. A shaky heavy breath escaped her as she once again watched a large amount of pre leave her cock, of which she angled slightly downwards to be as close as she could get to her little sister's mouth, feeding her every bit of big sister pre. She stroked, uneasily and hesitantly, throbbing and twitching. In the base of her core, she felt it building up. Her mind was still blank, the turn of events making it difficult to think of anything but using her little sister's mouth like this, and the orgasm continued to build unabated. It was only when she was just moments away from cumming, just barely crossed the point of no return did she snap back to the reality in which she lived. There was no stopping it. She tied to clench, tied to hold back the orgasm, her hand stopping and grabbing the base of her dick, nails slightly digging into herself as she struggled and struggled and struggled to hold back her orgasm, struggled to not cum all over her sleeping sister's face, something that surely no one could sleep through, struggled to not give her little sister her first facial, struggled to not ruin her life. Her cock twitched and bounced and the intense warm feeling in her body continued to build, focusing right on the base of her dick next to her hand and traveling up her cock. The only course of action, her hand moving before she could even comprehend the thought fully, was obvious. Her hand followed the feeling up her cock, angling her tip lower and lower until it pressed against her sister's lower lip.
The second she felt the warmth of her little sister's lip touch the sensitive underside of her cock's head, she came. Her body tensed violently, and a huge rope of cum shot out from her cock as her balls lurched. It hit her little sister's tongue hard, splattering the inside of her mouth, soaking it, drenching it, staining it, ruining it. The second rope came, a mind destroying wave of pleasure rolling over her big sister, a silent moan escaping her drooling mouth as she filled her little sister's mouth with cum. Rope after rope of cum shot out of her cock, every drop ending up in her sleeping little sister's mouth, every clench of her sack promising another load delivered right against her little sister's tongue and tonsils. The long night of edging, filling her little sister's mouth with pre, the hardest strongest orgasm of her life, ending slowly and over many minutes, her cock dripping seemingly unendingly against her little sister's soft lips. As the ropes died down, her breathing stabilizing, her eyes rolled out from the back of her head to look down below her, staring and burning the visage into her mind; her little sister, cock against her lips, mouth full of cum, sleeping peacefully. With one last stroke of her cock, her little sister's lips sealed around her tip, instinctively sucking gently and swallowing the large amount of liquid that had ended up in her mouth. The sound of her swallowing her cum, seemingly so much louder than the quiet night around them, made her leave one last strand of pre connecting her tip to her little sister's lips as she pulled away shaking. Barely able to shove her dick back into her panties, she was only just able to lean to the empty space on the bed next to her before she collapsed, all strength lost from the ordeal she went through. Panting, laying on her back, upside down on the bed, she stared at the ceiling, wondering what the fuck she just did.
"hmngh.. mmn.. nn.. sis..?"
She froze. An unmistakable voice. Shit, did she slip up right at the end?
"mmn.n… hehhe..he.. hhii.. how was.. mmn.. your night..?"
She blinked a few times, before giggling to herself, leaning up and rotating to lay down next to her sister, her little sister gently grabbing at the air next to her before finding part of her big sister's sleeve and sleepily grabbing hold.
"bleh.. my mouth.. tastes weird.. mm.. water..?"
As she grabbed a glass of water for her little sister, trying to calm her nerves and adrenaline, taking deep breaths as her sister sat up and rubbed her eyes, still holding her plushie, she tried to remember what she had done with her friends, to tell her beloved little sister about the wonderful night she had had.
