Whereart thou sling?
And before you comment on my subject, the phrase 'Whereart thou' does not ask the question of 'where.' 
meh, slingshots are sexier
Im with you 100%...dont get me wrong one pieces are sexy but...
Slingsuits are sexy if you want to focus on the breasts/cleavage, and have a nearly no-hands mammary intercourse (tit-fuck) session and without any clothing getting in the way. I love it myself.
But there are still two things to be said about one-piece suits.
1. They really show off the hips, hourglass and thighs of such an appropriate woman, maximizing her curves and minimizing her stomach (as some men prefer)
2. They can also provide a nearly no-hands mammary intercourse session, plus hide a lot of sperm as a man "shoots down" her top
The first can be a limitation when you're trying to access her "apex" while still enjoying those covered curves, although some suits (and most teddies) do have a snap crotch. But the more extreme the form, especially on a hourglass (or stocky apple-hourglass), the more I lust. For a more self-conscience, fuller woman, the snap crotch also means she can still "leave it over her stomach" while she is either serviced (orally) or speared by her lover.
I have had the pleasure of doing the latter at the beach, and having my lover wear her suit around for hours with most people believing it was just a water spot or, later after it dried, some sand spot. I had one F-cup lover take two shots throughout the day, and her cleavage and stomach was caked white when she dropped it that night (she didn't go into the water, so it was cum everyone saw in her suit, not a "long lasting water spot"
).
I also think people forget that one-pieces can have a slingsuit-like start with a deep plunge down her cleavage. This is not only an ideal suit for a busty, but fuller woman (especially apple or hourglass), but it can enhance any mammary intercourse more like a slingsuit, but better for cum depository into the suit (the head and upper penis stays inside the suit, but the cleavage and bust still "bulge out" around the lower penis and stem outside the suit). And if the woman is really busty, it can more "hold underneath" (with a side-bulge) the breasts like a busty woman in a bikini top, all while maximzing the lower curves while minimizing the inner bulges of her gut.
This board's greatest poster,
Prophecy, mosted a most excellent set of
Sheila Grant with a
first pic that highlights a teddy that is much like this.
My all-time favorite, non-nude model,
Yoko Matsugane, does an even nicer job with such a similar outfit in both outer and inner wear, especially at her heaviest where both her breasts are most full and hanging as well as her hips are very wide and hourglass very extreme (while still being slender).
