Through Walls
As the sounds that could only be described as "screams of pleasure" came echoing through Ise Nanao's quarters, she grit her teeth and rolled over.
She almost started imagining it, her usual iron-clad resolve slipping under the pressure of almost-sleep and sheer horniness. After all, no one is fully lacking in a libido. Sex is perfectly normal, she reassures herself. However, imagining one's taishou fucking another original member of the Gotei 13 was a little over the line.
Although it definitely sounded like a good fuck. The screams were only increasing in volume untill they finally culminated in her taishou's name: "Shunsui!"

Shaking herself out of a decidedly downward-spiraling train of thought, Ise Nanao made a mental note not to wake up her captain untill she was sure the other captain would be gone and forced herself to sleep, despite the curling ache in her stomach.
