The sprite work here is genuinely unsettling in a way I don't think the creator intended. Peach's eyes are these blank blue dots that never change expression while Bowser's cock, rendered with way more detail than anything else on screen, stretches her jaw into a shape that defies basic anatomy. I kept clicking just to see if her neck would snap. It doesn't. The animation loops are maybe four frames total, this jerky piston motion that reminds me of those old Flash cartoons on Newgrounds where you could tell someone learned tweening about twenty minutes ago.

The sound design is just... Mario jump noises. Every time Bowser thrusts, it plays the coin collect sound. I'm not making this up. You get this pavlovian response where you hear that familiar "bling" and your brain expects a mushroom powerup but instead Peach's throat bulges in this crude pixelated way. The cumshot mechanic is tied to a meter that fills up based on how long you hold the spacebar, and when it triggers, Bowser makes the same roar he does in Mario 64 when you throw him into a bomb. I laughed out loud the first time. Then I felt weird about laughing. Then I kept playing anyway because honestly, what else was I going to do with my evening?

The swallowing mechanic is where things get genuinely bizarre. You have to time a second spacebar press to make Peach gulp, and if you miss the window, cum just sort of dribbles out in these sad little pixel droplets while a distorted version of the "you died" jingle plays. The game calls this a "facial abuse" fail state. I failed it three times before I figured out the timing. The whole thing has this bootleg energy, like someone ripped sprites from a ROM and fed them through a blender with a bunch of hentai tropes they half-remembered from browsing fakku in 2007. There's no game over screen, no win condition, just this endless loop of degradation set to music that's clearly the underground theme played at half speed. I think the koopa king would want it this way.
