It is more like animation player than interactive sex scenes and there is only a little bit of interactions well here we go with pros and cons : ( Version 0.7.2 )
The Good :
1) Animation
It is seriously top notch. There are collisions,butt physics,etc. You can literally immerse yourself in those scenes since artstyles are devastating in a good way.
2) Voiced
Yep your waifu is voiced and she talks in english, you can literally hear her a little bit of moans and ragged breathing and there are not much of her voicelines.
3) Copulation sounds
There are some copulation sound effects such as when she's cumming and when the protag is fucking her.
The Bad :
1) Lack Of Animations
There is only one sex scene available i.e doggy style and thats it
2) Only one waifu available
Only Makima is available and the rest will be coming in future.
3) Lack of Interactions
There is not much to do in sex scene except increase the pace of thrusting, pick the dialogues you want to say and there is occasional slapping her ass cheek.
Conclusion :
It looks promising, what captivated me were able to pick up waifus from various anime and artstyles. Sadly only makima is available and only one sex scene. Well, this will be awesome in future when it gets more waifus,sex scenes and more interactions in scenes. Right now it is bare bone. You can definitely pick it up if you wanna do quick fap. Anyways, I will keep an eye out for future updates and will edit the review.
