Wife had been reluctant to use her dildos, which I got so she can experience bigger cock. When she does use them she goes nuts, but plays it down after. I am going to suprise her with a sleeve. I am trying to go realistic, but functionality is most important. Any recommendations? I will keep you posted once I use it to share how she responds. She maxes out in depth between 6" and 6.5" but moans like crazy when they are thick.
