[COSCOteikoku (sella)] I was reincarnated as a villainess in an otome Game who was a futanari in her backstory [Erelzen]

Reincarnated into the body of an otome game's haughty villainess, a busty, drill-haired heiress discovers her secret full-packaged futanari anatomy — a huge cock with heavy balls straining beneath her pristine schoolgirl uniform and stockings. A chance reunion with an equally endowed elf beauty with massive breasts reveals a matching endowment, and their rivalry quickly melts into an intimate pact to explore simultaneous insertion only they can share. Joined by a soft, big-assed kemonomimi already lost to creampie-drunk bliss and eager frottage, the villainess embraces her hidden nature and vows to spread the magnificence of futanari pleasure together.
