Right, another one of those proof of concept things that's basically a fap snack. Eternal Bonds, the full game, isn't out yet. This prequel is a kinetic novel, so you're just clicking through, no choices, which honestly my brain appreciates after a day of spreadsheets. The 3dcg is deliberately unpolished, a bit stiff, but it has that weird charm like those early renders people used to post on forums. Uncanny valley but make it horny.
The setup is a male protagonist, some kind of flashback to a beach trip. My guy is basically a void with a dick, which is standard. The whole thing is about his girlfriend, I think. She's in full exhibitionism mode, getting herself off on the sand right there, then it moves to a pretty detailed handjob.
