I love aphrodisiacs in general. Any girl that has them, a type of venom or pheromones is boosted. Especially pheromones, which is basically what claustro's evaporated acids are. It's why horc is so high on my list as well. I want a girl who messes with my brain and smells/tastes unnaturally addictive.
There's something nice about how sacco does it too though. Once you're in, you're stuck soaking in her acids. The close confines of her sack lets her get into some kinky sex positions, submerging you all the way just to get your face level with her crotch. Forced against each other, skin-to-skin friction can't be avoided. The acid rubbed into your skin makes you feel every rub, bump and pinch 100x more. Her jug smothers sensations from the outside, so all you can focus on is her sweet scent, syrupy taste, plump body and crazing eyes. When you're inside, all that exists is you and her. It's a mind melting experience fiting her name.
Claustro hits some of those beats, but I headcanon their scent is stronger (as their acid is most effective when breathed in), and I enjoy a smug brat doing that to me.
