Girl Artist by Ben West

She wanted to paint the male figure… undraped!
Did painting really interest Dulce Gerau? Or was it the bawds and beats, the handsome male models, or… was it the bewitchingly warped women it provided?
A Bond Novel Of Female Perversity!

From back cover:

There was nothing that beautiful Dulce Gereau did not shamelessly try-no taboo she did not violate. Was it because Dulce, born out of wedlock, inherited passions too wild to control? Or was she merely succumbing to the careless morality of the young painter, living among people who took sexual indulgence for granted..... It was no surprise that she threw her seductive self at such as Wallace Harper, who paid her bills. But it was carrying matters too far, when she sought men in the streets and invited then to model for her. Worse still was her tumultuous fracas with shapely Jane Yancy, who wanted Wallace--and with pretty Lillian, who wanted no men at all. Obviously, Dulce's desires--and those of her friends--were unnaturally warped!!
