Lf Doujin
I think its an ntr at least, I'm not fully sure, itd be a netorase to be specific
All i remember is, girl is giving mc a lying down blowjob, and begging practically saying ike he wants to have sex and not just cum from a blowjob, she doesnt listen and just continues, i think she even likes it when he does giggling maybe, thats why I think theres a bit of femdom, not like anything big, but its there
Girl also has regular ish proportions for an anime woman, not like the really huge ones in some hentai
I know this isn't a lot to go off, but idk what else to look for, ive been hyper fixated on this for the past week and a half, this is my last attempt to try and figure out what it is
Edit: It wasnt colored, the girl had dark hair, MC wasnt big and muscular, he wasnt small and scrawny either i think, he was regular sized. I think it doesn't have more than one part, but i could have just not seen them yet
Oh, its also not part of the Terasu MC, Laliberte and Ratatatat74, and its not of the same artstyle, kinda, idk if this is helpful
i think shes a wife, not a girlfriend
