Note – This was posted on r/sex and the mods deleted it. One of them was kind enough to redirect me to this sub-reddit.
Let me start by giving a background on how my girlfriend and her sister grew up. They are very close in age (about 15 months apart) and are from a very rural area in the mid-west. The house they grew up in was a farm house with one bathroom and the closest neighbor was about a mile away. Because they had one bathroom it was not uncommon for them (their parents and the sisters) to be in the bathroom all at the same time and it never bothered them. To this day my girlfriend and her sister when they are running late would shower together, but I am getting ahead of myself. More on that later.
Three years ago they lost their dad and about a year later they lost their mom. They both moved to a city in the Northeast where I work as a junior internet security analyst. I met my girlfriend through work.
