Have quite a number of Serena films probably for the same reason -- beautiful strawberry blonde pits. One not listed in the database is "Aunt Peg" (1980). She has only one scene -- a three way with Juliet Anderson (Aunt Peg) and Mike Ranger, but it's a good one. Couldn't find a VEF thread for it but it is available on the usenet. Also scene referenced above is available as a Swedish Erotica loop as below:

Another good one is "Honey Throat" (1980), where Serena has two scenes (one with John Holmes and one with Eric Edwards). It's already in data base and as have noted before, Patty Boyd has a lesbian scene in it with Arcadia Lake. Ms. Boyd almost always appeared shaven, so here's a "mistake" but her pits are quite delicate (but still lovely). No VEF thread for this film, but it is available on sister site as well as others.
