There was a game I played before.It was like a lifesim which you were choosing what to do with your time working, or spending time with your girlfriend.There were items to purchase to gift your girlfriend.It had anime style graphics.Your girlfriend has a sister and at start she hates you but you could also seduce her.It had some voice acting and girlfriend was calling mc senpai.There was a scene in which gf's sister was rubbing mc's dick with her foot.Anyone knows this game?
