GAR-244 - Exposing my erection to a hot gal in a mixed bath while her boyfriend is oblivious!

A popular mixed-gender hot spring where anything can happen. I sat in the boyfriend's blind spot and flaunted my erection right in front of his girlfriend. Once she caught a glimpse of it, she couldn't focus on her boyfriend anymore. Now, she's desperately looking for a way to ditch him and get her hands on what she just saw.
