A 24th female massuese has just filed a lawsuit against Deshaun Watson ... alleging the NFL star was sexually inappropriate with her during a massage session -- and the new allegations are graphic.
In the suit, filed in Harris County, Texas on Monday, Katy Williams claims Watson got in contact with her back in 2020 to set up a professional rubdown.
On Aug. 5, 2020, the woman says she massaged Watson without issue -- and the quarterback gave her $100 for her services.
A few days later, however, Williams says during a second massage session with the QB, which she says took place at her apartment, he became very inappropriate.
