Sarina Matsumoto (Patreon)

...and here we have Sarina-san in bed, tied up with nowhere to go wearing tight, shiny latex and unable to have much of a say about it.

Not long after she gets a bit of a surprise (hint: apparently a little bit of protein isn't bad for the skin...)

Anyway, you'll find this, along with a single alt, in the Dropbox.  Enjoy!
