Ruf and I both had a go with this one. It was bigger than the white vibrating Nexus Duo that we tried at the same time but, lubed up and stretched by the other insertion, this went in quite easily and he enjoyed having me 'rummage' around with it as we tried to locate his prostate whilst he was pleasuring himself. The little hook handle is very clever.
When the tables were turned, the penetrative part is not as long as the average anal dildo but the shape of it felt very nice as he jammed it against my perineum and waggled using the handle. In conjunction with my tulip clit stimulator, it was certainly very pleasant although I'm not sure it was hitting any particularly sensitive pleasure spots.
