Oh man oh man oh man!
For starters, let's talk about pinching:
I was worried because these toys do look like CLAMPS and I was afraid they'd squeeze my poor nipples too hard. I'm very sensitive to pinching, but the adjustable screw means that if you LIKE having your nipples squeezed, you can make it give you a tight pinch. But if you don't, you can rotate the screw so that it applies juuuuust enough pressure to stay on your nipples. Additionally, if you'd rather have it hold itself just behind your nipples on the areola area, you can do that instead of squeezing into the nipple itself.
Now, let's talk about the PLEASURE:
I was amazed that a little squeeze and a light vibration could turn me on so much. You know that feeling when you're getting aroused and your nipples tighten? Imagine that, but multiply it by a thousand. I felt sparks of pleasure that seemed to go from my nipples straight to my groin, where I could feel heat pooling as I went from "kind of turned on" turned on to "F*ck Me Right Now" horny. I was playing solo the first time I used these, and my climax was much faster and harder than I was used to with just this little bit of extra stimulation and foreplay.
The next time I used them, I used them with my partner, who told me that the black clamps looked extremely naughty and XXX rated (despite the fact that these are PERFECT for beginners!) He liked to pull on them a bit as I got close to orgasm which felt AMAZING. I would recommend these for anyone looking for some SPICE in the bedroom without going off the deep end. This was a fun way to dip my toes into a different sort of sensation and I absolutely LOVE the results, and so did my partner. Another bonus: The Black color is nice and unisex, so I can use them on him, if he'll let me!
