Well, the Dorcel installment (La Secrétarie) features three scenes starring CARLA (the two Dps were shot back to back however).
At first we catch her in action on bed with two men as a lurker with an hidden camera takes some nice pictures of the secret "business" meeting
Reverse cowgirl vaginal while blowing and jerking the second guy (ball licking too), frantic action as we spot her high heeled shoes lying on the floor...amazing nylons still on, by the way

)...the older man jerks himself while kissing her, the same guy masturbates himself while fingering her pussy during the following vaginal...a doggy vaginal penetration is soon combined with more blowjobs and handjobs with plenty of tongue slapping using the hard cock (nice split screen shots..we are back in the seventies).
Bruno licks her asshole a bit before a nice doggy anal turning soon into a DP (balls deep anal, by the way)...she spreads her ass moaning...
Sorry no climax, but she will have another meeting with the same guys later on the same movie...
