1 Dick 2 Chicks 3 (Red Light District)
Sperm Swappers (Elegant Angel)
1 Whore + 1 More 2 (NXT LeVL; Mark Wood did it)

In general, my favorites series for this are:

Double Decker Sandwich
(Zero Tolerance; babes are busty, 1 and 3 I liked better than 2 and 5, have not seen 4 or 6)

Blow Me Sandwich
(Zero Tolerance; a blowjob series, all 6 are great)

1 Dick 2 Chicks
(Red Light District)

Cum Swapping Sluts
(Red Light District; only the 1st 7 are watermark free)

Double Play
(Digital Sin)

Honorable Mention:
2 Chicks and a Cock (Colossal Entertainment)

I have not seen every volume of every series mentioned above, but I have seen enough to give a general recommendation for quality.

In addition, the following two series have gotten good reviews, although I have not seen them yet:
Cum Swappers (Hustler Video)
Cum Catchers (Smash Pictures)

Read some reviews for any of the movies or series I have mentioned to learn more.

This should give you a good start!!!

Double Decker Sandwich #6 was good though. Can't say I enjoyed every scene in it, but what I did enjoy was pretty hot.

Many of the GGB movies contain some very good scenes , but many follow the same formula and , often , there is limited contact between the girls, during the sex. What's very important , also , is that the "cum play" should be alot longer at the end. The girls should not only swap , they should cum kiss ALOT before swallowing ... then kiss some more.
