I opened up our toy drawer yesterday to get some batteries and moved the suction cup dildo a bit. My hand came away a little greasy! When I put it back last time I cleaned it with soap and water in our bathroom. It wouldn't be greasy unless it was cleaned with the disinfectant toy cleaner that we have!
I think my wife used it on her own! My cock got instantly hard at the thought of her using the "big boy" to fuck herself when I wasn't home. I hope that this is the case and that I can get her addicted to using it! Fuck yeah!
