The girls look good but other than that I didn't find anything interesting. It feels somewhat repetitive, there is no need for day and night cycle like the one presented. Also the main character looks out of character, he definitely does not look like some slacking junkie he looks more like some gangster slash former comandos (or something like that). Definitely he is out of place, out of character... to have a physique like that, you can't just go around day by day and sit on your ass all day.
Also all characters look shallow, they don't act naturally, no girl would make sex like that on the second day she sees you (without some good reason), is she a pervert?!, she didn't look or act like a pervert. Also the situation did look awkward, it was just a pretty normal conversation, they were not in a bar or on a date, she just showed up and wanted sex, like she was his girlfriend for 10 years already. Jenny acted unnaturally, I would understand if she was some super kinky devilish character, but she acted like a normal girl even when she asked for sex, she was shy. Also MC behaviour was unnatural too, most normal men would be really startled if an almost unknown girl knocks on their door at the morning and hops on them like that wanting sex.
It feels like the game has no actual story and no characters. If the author wanted to show a sex scene it could have been some erotic daydream or something like that... also the sex scene was uninteresting. It was literally (cock goes in -> cum -> out)... that was it, worse than a sex with a prostitute, no feelings (from both sides) no nothing... it was like it was nothing... Was she a robot?! Only a robot girl could do what was showed... but then it would have been probably more interesting, because a robot girl can also do things a normal girl could not do... soooo... author should try to write a better story or have a story at all, because there is no story in this game. It's just a day night simulator with some pictures and basic conversations. OK I'm probably too critical but still, the game needs better story, or otherwise some good CGs are just wasted.
