LOVE THESE!
i ordered a fair bit, these were what i wanted to open most. They slide in nice and easy with a touch of lube. The power these things give, AMAZING! I went for a quick walk and when I came back all i could think of was having them pulled out nice and slow before being fucked.
Trust me ladies, these are something you want to have!
Only issue, for a set of 4, i think they would be a little big for most. I've been trained so they are easy for me, but id suggest a 2 set for beginners
