looking for a specific hentai manga through description (image not related)

sorry for doing this but there's this manga that has been stuck on the back of my head for literal years and i can't find it no matter how hard i looked so i was hoping yall can help me

although i can only provide a description of the story of the manga :
there's this oh so perfect and rich girl who's actually a pervert who watches porn all the time when someday she gets harrased by a group of thugs who wants to have their way with her while she was shopping for porn and then the protag who is a delinquent/thug also runs in and "saves" her without knowing that actually she's a huge pervert that is okay with the group of thugs having their way with her bla bla bla and then they fuck the end

that is all i can remember and provide for said manga thx in advance for anyone kind enough to help me
