Played in VR with Index.
Both girls are quite cute, voiced and you can impersonate either of them.
The outfits are modular, with skirt, panties, bra, sleeves, shoes, and gloves controlled separately, but there are no alternative outfits: it's just the one. Thankfully it's nice and quite erotic.
The game has two main modes, the roaming-posing mode, and the scene mode (activated by being close to the bed, bathtub, sink, or sofa).
Unfortunately the posing mode is an utter jank. It's super easy to grab the girl unintentionally and ruin the pose completely. Even getting them laying flat on the bed with legs apart (to use the onahole or dildo) is a challenge. While it is possible to play with breasts (both own and the other character), it's not possible to play with the dicks.
Thankfully the scenes are quite nice, with a variety of standing, sitting and laying sex, with the player character both on the receiving end and penetrating. Mutual masturbation is also included.
The mirror mechanic is also really nice, and adds a lot to the game. Shame it renders at visibly lower resolution and there seem to be no settings to change that.
Points deducted because of just one outfit (and limited interactivity of it, it's not possible to lift or roll up the skirt), the horrible controls in the free-roam/posing mode, and problems with scale (for some reason the game insisted I was like 130cm tall).
That being said, if the online mode works as advertised, you have somebody to play with, and you both have full body tracking (hips especially), it may be one of the best games out there...
