This is part of a series, but this part can easily be read on its own.
**TLDR**: my sister and I have been ‘together’ for a few months, and we spent most of last summer fucking. This part takes place after several hours of sex, while we had the house to ourselves for the day. If you’re curious about what we were up to before this, you can get started [with this](https://www.reddit.com/r/Erotica/comments/k24yvo/me_and_my_twin_sister_fucked_on_a_hot_summer_day/).

Just like every other room in the house, our mother’s bathroom was hot. An uncomfortable, pressing heat that seeped right to the bone. Even when I was nude like this, the air felt awful. This summer really had been merciless.
There was a lot of space in the room: a closet, a walk in shower, a bath, a toilet, and two sinks – all in a comfortable palette of smooth tan. More importantly, there seemed to be a distinct lack of Noelle. Just as I was about to look for her somewhere else, a cheerful voice piped up from behind the glass of the shower.
“In here, babe!”
