Hard nipple torment - vacuum pump orgasm

1ATOYS ( premium silicone dildos since 1999 ) presents Hard nipple torment discomfort vacuum orgasm. Only with the vacuum pump, the slave got no orgasm, I checked out this. He told me that something was missing. So I wanted to check out whether intensive treatment on his nipples is the missing part. Pumping his cock with the vacuum pump and some nipple games. I got a good cum result with needles, but here I want to find out if he will get an orgasm only with clamps. Therefore I used first some nipple clamps with a little chain on them. Nice to pull the nipples a bit, but not the desired action, so some more heavy clamps or better two pairs of them. Better but not perfect. So I used the strong towel tongs on his nipples. These clamps are really hard to take and a little more discomfort on the nipples, but if you can see it here in the video, just suitable for him. Just as I used them he got a wonderful orgasm in the vacuum cylinder.
