I have been looking for the next step up for anal toys, something a bit larger than the existing dildos that my wife and I own. This set has filled that need. I have the largest one for myself, and the medium for my wife. I had a bit of slow stretching to do the first time I tried the big one, but managed to get it ALL in. This morning I was able to insert it with a minimal amount of warm-up. Thank you, it was an economic set, yet functional. One of my buddies has a rather large cock, so this is a good tool to use before he visits us.
