Ace12345's review of Lovehoney Perfect Pair Silicone Nipple Suckers

A bit of an odd sensation, very different from things like clamps, but not in a bad way. They generate an interesting pinch and pulling sensation, and it's quite easy to vary the intensity by initially compressing the heads more or less to generate the force you want.

They fit on quite well and form a tight seal against your skin. They'll actually stay on well unless pulled quite hard if you set them quite tight so can be used to move around the breasts themselves to a degree.

They are quite sturdy feeling and easy to clean, though they'll take a while to dry due to the bulbs.

Overall they're definitely an interesting addition to foreplay, especially if you've already tried clamps. Be careful not to set it too tight for yourself as they seem to increase sensation faster than clamps so could quickly become overwhelming. For the price, they're definitely worth trying if you think you might like something similar.
