HSODA-110 "Sorry for making you embarrassed." I was taken to a mixed bath hot spring by my aunt, and I got an erection when I saw her naked! Plus, there were women all around! I was worried about getting caught, but then my aunt started jerking me off sec

I was taken to a mixed-bath hot spring by my aunt. Suddenly, there were only naked women around me, and my crotch was rock hard! No good! Shrink already! The more I think about it, the harder my crotch gets. And then there's me acting suspiciously. My aunt noticed me like this and reached her hand towards my crotch! Apparently, my aunt thought that if she jerked me off once, my erection would go away and I wouldn't be embarrassed. However, halfway through, something seemed off with my aunt!? She was clearly aroused! At first, it was out of goodwill, but now it seems like she's just driven by lust! As expected, my aunt didn't stop at just jerking me off and moved on to the next development... Both my aunt and I got unexpectedly horny, lost control, and the acts kept getting dirtier! This is the first time I've been this aroused.
