The suction on these is stronger than I expected, and the volume boost is noticeable after just a few minutes. We used them as a warm-up before things got serious and the pump effect made foreplay a lot more fun.

Wasn't sure these would do much, but the vacuum effect really does plump things up noticeably after a few minutes. The cups fit comfortably and stayed sealed the whole time, which surprised me. Fun little addition to foreplay.

The vacuum suction is surprisingly strong and the cups stayed put the whole time, which made the whole thing way less fiddly than I expected. Volume boost was definitely noticeable after a few minutes.
