It is often difficult to substantiate a performer's "firsts", and these two videos claim "first anal scenes caught on camera" for the females involved. Let's give them the benefit of the doubt because it's a good marketing hook.
The highlight of the average Vol. 1 is undoubtedly the enthusiastic and unrestrained Lana Woods. In addition to her awesome blow job, she winds up very willing and eager for a very explicit and clear boff in the butt. The other two gals (thin brunette Sandra and Holly Heat) throw in a mini-tease before their anal cherry is plucked from their sexual repertoire.
Vol. 2 starts with blonde and top-heavy Brooke Dunn (a cross between Victoria Paris and Sasha Savage) teasing her beau with clothing changes before she literally drags him off to a hot tub for a clinging-clothes blow job with direct eye contact to the camera. They wind up inside for the expected anal, and it in long-lasting, deep, and very easy to discern. Jeff Scott gets tall (6'1") and dark Tamisha to open wide for a close-up butt filler. Finally, busty Tanya Storm and Jeff consummate the anal tease that they hinted between scenes as being forthcoming. After a long warm-up in her adjoining orifice, he slips right in the old poop chute. Brooke returns for a quickie (non-anal) ending interracial scene. Vol. 2 gets higher marks; a series worth stocking.
