Concerning the female threesome at mid-right:
a) It isn’t just that there’s no lascivious attention to their bodyshapes. The body poses and facial expressions aren’t inviting to viewer or sailors either.
b) You don’t see them as separate individual women but as a sort of threesome-blur. On closer inspection you seem to be looking at a three-headed two-bodied amalgamation, with the middle head sort of sprouting between the inner shoulders of the woman to her (its?) left and the woman to the right. Only with very careful study can you make your eyes track down the middle head and join it to the black-clad body. And conjure up the third woman as the head with the amused grin attached to the blue skirt 9/10ths hidden behind the other two women’s bodies. Of the three of them the only one you can sort of focus on easily is the one closest to us in the sunset-toned dress. She’s the one with the snooty haughty expression. Not only is she very flat-chested, her chest is very bony. (Nice ass though).
c) The one with the rather naughty amused grin is the most likely owner of the hand that seems to be contemplating a grab at the rounded sailor ass that the women are walking past.
ALSO behind the peculiar threesome, in goldenrod, that’s a very sexually ambiguous person who is rejecting the attentions of the seated sailor. The hair length and ruffled collar (and heterosexual normativity of course) suggest female, but something about the body shape is more reminiscent of a young boy drawn to adult size (think little lord fauntleroy). If that’s a female she’s the only one not wearing high heeled shoes. And this person’s other hand seems to be reaching for a feel of the snooty-haughty woman’s ass while the passed-out sailor’s hand is positioned for a backhanded brush against ambiguous-person’s butt. All three ass-grabs are visually suggestive when you only look at the hand and the relevant ass, then seem to be just accidental juxtapositions when you back out to see what the owner of the relevant hand is doing, but that’s a lot of accidental juxtaposition.
