I like the game's static erotic art and a few of the erotic scenarios at the beginning.
However, the game is like 15 mins short and I suspect half of the time is you walking slowly around the map to do chores and if you didn't read the dialogue properly, you will spend even more time walking and clicking everywhere as there is no quest log.
The game is more of a kinetic novel than a game. The cycle is basically, you get a task, you do your task, you trigger a ntr sex event when you are done. Rinse and repeat. Because it is a kinetic visual game, there is 0 side events or events that you stumble upon or be able to control/avoid/change/find.
Despite the art being erotic, the animation is very bad. The animation is no different from getting a static image and "moving" it by resizing or dragging the image. The girls have static faces.
The ntr is either:
a) just you, the youngest brother, having no sexual history with any of your family members(3 older sister and 1 mother). You are ignorant to what is happening around you.
b) your father who is only mentioned in text in the game's intro and feels like he has no relationship with anyone in the family. The children don't missed their dad, the mom is only sad she hasn't had sex and nothing else.
c) one of the girl's boyfriend, who is also mentioned in text once during one of the event.
Personally, if this is considered ntr, then I believe this is one of the worst representation of ntr.
The personality of the women in this games are just street whores. On the very first day, with almost 0 conversation, all of them decided to tit fuck the old man and the ugly boy (Who is not you). Even worse, for the sisters, they casually stripped in front of the ugly boy and almost all the time is the one who initiated the sex. The women all have no personality, the only difference they have is their hair, clothes and eye color.
The events has no risk, you only stumble the AFTERMATH of the sex. The girls all initiated the sex with the ugly boy. And when you trigger the event, you will just be flashbacked to 15 min - 1hr before you stumble upon the aftermath, making the gameplay where you do stuff even more irrelevant as you aren't stumbling upon the sex while working or you(the player) are unable to see the sex while you(the protag) is ignorantly working nearby.
In conclusion, this is just a hentai gallery. It is not a game. If it is ntr, it is one of the worst ntr I've ever seen and there are far better ntr doujin, visual novel or even games. The animations are bad that I've seen better from animated time stop aka animation wher the guy is plowing a girl, who is static. Just like another comment, I would rather just see the images then play this game.
Finally, if I changed the synopsis of this game, nothing will change and nothing will be lost:
"I'm the bastard son of the female owner of a whorehouse. I earn my keep working as an errand boy. The whorehouse is losing money and my mother, the female owner, is deciding to fire and kick out 2 of the 3 whores.
Today, a old man and his ugly son came by. The old man bought my mom, while his son only have enough money to pay one of the whores.
Now, the 3 whores are competing for the ugly boy's attention so that they can still remain employed and not end up homeless. They used cheap tactics like flirting with the boy or "bumping" into him or casually invade the bathroom and stripped. Welp, time to do my errands then."
^The fact that I changed the entire story and nothing was lost, shows how non-existent the story and the characters are.
