What Alice had expected was to stay over with her sister in a hotel room for a few nights. What she had not was how her sister barely wore any clothes when she slept, and that their bed would be small enough that they needed to sleep pressed against each other. Alice soon finds herself distracted by her sister's body, but will she end up going further than just looking or manage to resist?
Apparently sleep was not in the cards for Alice tonight. When she couldn't sleep... there was one thing she usually did, but would it be alright to do it in this situation?
Alice contemplated for a while. But eventually, she decided to just give it a try anyway, despite... well, despite having her sister sleeping next to her in her underwear. She seemed to be pretty soundly asleep anyway, so it's not like she would notice or anything.
Alice stretched her arm down towards her own underwear, and slipped her hand inside. Rubbed her finger around the edges of what was inside. Slowly got wetter and eventually inserted her finger, playing around with it within her vagina.
Perhaps doing it like this, with her sister sleeping next to her, was... well, it at least felt like it should have felt wrong. But Alice couldn't actually bring herself to care that much.
If anything, instead of closing her eyes and imagining something hot the way she usually would have... somehow Alice found her eyes constantly trying to make their way towards her sister, drawn by what was visible of her mostly naked body. It wasn't exactly something she tended to think about in everyday life, but somehow it made her notice that her sister actually was pretty sexy.
Yeah, rather than just looking at her... it would maybe even have been nice to actually do it with her.
