Seeing Rei Tachibana without her uniform is weird enough, but then the glasses stay on. Always. Something about that detail got me. They didn't animate it sliding off or fogging up or anything. Just these big nerdy frames locked on her face while everything else... expands. And I mean really expands. Those tits look like someone opened a valve and just left it running. Not a complaint exactly but it's almost comical until you click to the cowgirl position and suddenly it works. The way the swimsuit variant stretches.

Flying Tree Frog's game here is basically a stripped down F-series thing where you pick outfits, positions, and then poke at her with either the dildo or the on-screen cock. The bikini option is the most broken. If you switch from the school uniform to bikini mid-scene the boobs reset size for a frame then inflate back. Nobody bothered to fix that obviously. And the dildo just floats sometimes, not even attached to a hand. Whoever programmed this was horny and in a hurry.

The sound though. Some weird wet loop that doesn't match the speed, and her voice clips are like three words on repeat. "Yamete" then moan then nothing. I ended up muting it and just cycling outfits while she was in doggy. You can't even see her face proper in that position anyway so why keep the glasses model on? The whole thing is jank but I kept going back to the schoolgirl outfit with the jacket open. Something about Rei specifically, not some generic hentai girl but the actual Pani Poni Dash character, getting defiled like a fucktoy. The nerdy tachibana girl who was always screeching about something in the anime now just taking it. There's no game here really, just a compliance sim with boob expansion bugs. Wish there was more outfits honestly. A Mrs. mode or something. But they made what they made and the big boobs toggle works I guess.
