Leslie's Secret

When Blake Conner discovered Les Wilson was stealing his firm’s intellectual property, he gave him two choices: prison, or one year as Connor’s feminized, personal sex slave. Shaved and dressed as a woman, Les is wooed and bedded by his boss. He rebels and suffers the humiliation of figging and a hard spanking. The humiliation becomes unbearable when he's locked in a chastity device.
