I have a male masochist’s deep and abiding love for having my penis and testicles weighted, clamped, kicked, etc. So naturally I enjoyed Teppycat’s story of exploring it:
Then I remembered I have a set of vibrating nipple clamps in my toybag. I didn’t attach them to T.’s nipples. I just clamped them to different parts of the cord around his cock and balls. They’re bulky (for nipple clamps) and heavy-ish (ditto), so at first all I did was lift them up and let them fall, repeatedly.
Then I turned them on.
I’m pretty sure he didn’t realize that they were vibrating nipple clamps when I attached them to the cord. (I doubt he was thinking very clearly — or in any linear fashion — at that point.) So suffice it to say that when I turned them on, it was one HELL of a surprise.
