Lawyers in Heat (1988)

A lawyers' buxom receptionist arrives early and plays with her intimate piercing. She is reprimand by a buxom secretary, who herself later pleasures a lawyer with a convenient bed in his office. Back in the lobby, the receptionist pleasures a lawyer too. Mistaking a scantily clad delivery woman for an applicant, the secretary takes her to assist pleasuring a third lawyer. The delivery woman then goes to please the first lawyer. Back in the lobby, the receptionist and secretary are joined by the second and third lawyers.
