Big sis “helping” her little sister jerk off, hearing strange faint noises coming from the younger girls room one evening, peaking in a crack through the door to find her little sister frantically working at herself, unable to find the rhythm, nearly finding it but getting flustered each time she starts to get close,
Watching her give up before barging in and offering to help, little sister reflexively covering herself and shakily telling her to get out, that she’s not supposed to see her like this,
Big sis chuckling and sitting down in the bed next to her, explaining that since they’re both girls it’s ok for them to be naked around each other, that it’s just natural, they’re sisters after all, that it’s not like she didn’t see her naked when she was younger anyhow,
The younger girl still nervous and uncomfortable not knowing what to say, big sister taking her opportunity to get in close to the girl and pull her into her lap, she protests, but big sister is so much stronger, and so much softer, her protests seem to wash away as she melts into the warmth of her big sisters lap,
She giggles down at her little brood before taking her in her much larger hand and getting her hard again, the little girl begins to protest, but quickly trails off, no match for her big sisters soft and skilled fingers, taking no time to get hard between them,
Big sister cooing at her, telling her what a big girl she is, what a good job she’s doing as she spits in her hand and returns it to the girls stiffness, working a slow gentle rhythm that sends shock waves through her little sisters body, all her protests are gone now, the only sounds she makes are the involuntary little whimpers and moans one makes when receiving their first hand job,
She’s quick to finish, starting to panic as she gets close, trying to grab at her big sisters hands, but in a flash her little wrists are restrained, held high above her head as she begins to pout and panic, begging her sister to stop, that it feels weird, that something’s happening, as she shoots what little load a girl her age can manage all over her big sisters fingers,
The older girl cooing encouragement at the younger as she convulses with pleasure, telling her what a good little girl she is, what a sweet little princess, what adorable sounds she makes, licking the mess off her fingers before releasing her sister, snuggling the little girl into bed and wrapping her in her arms, petting her hair and leaving gentle little kisses on the back of her neck as she slowly calms and eventually falls into a deep sleep,
