/HB8*0@FF20:戯ィ牙.EXE
Just play this game in detail(for some parts) because I just found HCODE.
Riruka X Ryuuga part is very interesing.
The feeling development step is very good.
Ryuuga(NTR guy) is very gentle with good sex technique he gently makes Riruka(the girl) arousal, then try to make Riruka ask for his sex.
At first, Riruka is very passive and not like Ryuuga, Ryuuga uses his sex technique and frankly confess and prise Riruka.
After they had sex. Riruka very like Ryuuga's sex but she doesn't know her true feeling(she may know but don't want to accept), She said something like since Ryuuga wants to be her lover she needs to check Ryuuga feeling by having sex.
After that in a few h events, Riruka is more active and Ryuuga also make Riruka ask for his sex or say a lewd thing, They become happy lovers Riruka is quite active about sex.
Finally, time skip, they are still a happy lover but Riruka need more extreme sex she thinks she wants many di*k at the same time and wants many people to see her(she just think but not mention) when Ryuuga asks her about why she uses a vibrator she gives a hint that he cannot do 2 holes at the same time.
So, Ryuuga seems to know her though and asks her, if she wants to try an orgy party. She says that she doesn't want Ryuuga unhappy.
Ryuuga seems to know her though again that she really wants but she cares about his feelings and little scare, so he says that they can go but just let another watch(it seem he will let her try exhibition sex first). Riruka happily agree.
The game END here.
If there are a few H events more should be much better I want to see exhibition sex and full orgy party.
I like this because the feeling development between Riruka X Ryuuga is good, not too force rape and character is not minded break, also I personally like a cute shy girl with a little sex experiment.
and
Does any VN/Manga similar to the feeling/relationship development recommend?
