New toy for my (35M) wife (36F) awakens sex crazed slut

My wife & I have been married for 8 years, I wanted to spice things up a little. I was always a little self conscious about my size. I'm average, but you watch enough porn & you think everyone is packing 12".

My real issue is stamina, I get too excited & I just don't last long. I was looking into pills & creams but I don't want snake oil & side effects. I stumbled upon penis extensions & I bought one from Amazon.

I didn't want to surprise her, so we sat down & had a talk with her. I told her I wanted to try something new & that I thought it could be fun. I showed her the toy compared to a dildo she has, I wanted to show her that the extender was soft, odorless & that I didn't consider it a threat. She took one look & said "that's huge", but seemed at least a little interested.
