Sharing trope but it's FMF

So I was reading { Graduation by Sophie Lark} and there was this scene, during MMC & FMC's first time they include another woman too. The threesome was too hotttttttt!!

So I want to ask if there's any book with this sharing trope? Where there's two women & and one man...please no reverse harem just sharing scene.

My no's ❌️: Cheating, OW drama. Fantasy, futuristic, omegaverse, historical, paranormal, aliens, sci-fi.
