Bubble de House de XXX 1

The story begins four months ago, when a certain well-known bathroom fixture manufacturer offered a shared house at a low rent as a condition for product monitoring. I thought I had been completely overlooked, but I was unexpectedly accepted as a backup candidate! I was overjoyed and moved in, only to find out that all the other residents were women! And to make matters worse, they were all my seniors at the same university! It seems like I'm in for a thrilling student life in this "shared bathing space".
