I keep thinking about that one scene in Amagami SS where the girl just grabs the guy's hand and puts it where she wants it. No words, no hesitation. That's basically this whole game's energy. The second sand game, whatever it's actually called, picks up with the girl already worked up and ready. None of that slow buildup stuff from the first one.
The quest system is weirdly simple. You click the guy's dick first, obviously. Then grab his hand and she starts using it on herself. I got stuck for a minute because I didn't realize you had to do that part multiple times before the sun cream shows up. The minigame aspect is basically just clicking things in order but the animations change depending on what you've done before. Once the cream is involved she starts shifting positions while you touch different spots. Breasts, his penis, her head, kissing. The rough sex tag makes sense here because it's not gentle. It's that desperate beach hookup energy where sand gets everywhere and nobody cares.
The cumshot at the end is what you'd expect. Nothing revolutionary but it lands. What bugs me though is the vaginal masturbation part feels rushed. Like they could've let that breathe more before jumping to the next thing. But I guess that's the point of these browser games. Quick and dirty. The beach setting is just a backdrop, really. Could be anywhere. The whole thing runs smooth enough on my phone which is where I played it, Chrome browser, no issues. I wish there was more variety in the positions but that's never getting updated so whatever. If you've played the first one you know what you're getting into. The quest structure keeps you moving forward even when you'd rather just stay on one interaction longer.
