Good afternoon everyone, this is my first post, so I hope it is in the right place. My fiancee and I recently(about 2 months ago) purchased an 8" dildo for me to use on her, seeing as I have only been cumming about once every 2 weeks I haven't been lasting nearly long enough. I have had a fantasy about fucking her with the dildo and not feeling it(having her ride me/etc) Just curious if you guys/gals have any recommendations for a strap-on to wear with the dildo (I have about a 42 waist, and I'm a pretty big guy). Vacu-lock is preferred.
