More of the first set, "Double delight" from Exciting 17, 1981-06
here.
rodox equivalent

More of second set, "Hot magic" from (Silwa) Backdoor Lovers 21, 1995-07
here. Considerable time gap but then Silwa often printed sets from several years prior. /shrug/
Not sure if the second set is the same model--breasts seem smaller & more separated than mystery's? Mystery has a spot on her left neck in a couple of pics. which I can't match on the second model.
Also no sign of (v. slight) double-chin which mystery has.
