This happened with my wife and I awhile back. I thought you all might enjoy it as much as we did. I am not much of a writer so hopefully you all can cut me a little break.

I have had a fantasy of sharing my wife for as long as I can remember. We have talked about this and she has said she would thinks this would be fun and trusts me. This last weekend we were playing around and I tied her up, blindfolded her and ate her beautiful pussy until it was just soaked. I quickly jumped off the bed and left the room. She began asking what I was doing and I didn't respond. I had run off to grab the cock sleeve I purchased earlier in the day. As I reentered the room I slid on the sleeve, put a condom on it to mask it feeling like a toy and lubed up my newly elongated cock. The whole time my wife continued to ask what was happening in a nervous and excited tone. As I finished up I told her to just relax, trust me, and enjoy what was about to happen. Her breathing quickened as I climed on the bed and moved over to her. I teased her still soaked pussy with just the tip of my now foreign cock and she jumped. I quickly lined myself up and began to slide myself and the toy into her. When I hit the half way point she gasped slightly and asked what was happening. I kept quiet and began sliding in and out of her slowly working deeper and deeper. With no response from. Me she continued to ask between moans what was happening and slowly began to exhale stamens like oh my God that feels so good. After working her pussy for a while I found a rythem and worked it until she came hard. I quickly pulled out ripped of the toy and the condom and slid inside her with my raw cock where I only laster a few short moments before I willed her up. Once I finished I pulled off the blindfold and she asked me what just happened with a devilish smile. At first I attempted to play it off that I had just shared her. However, after a few moments it was clear that she did not buy it as I had not talked the whole time she was being filled by the larger cock. I quickly caved and told her what happened and and shower her our new toy. I have since fucked her with it multiple times. Needles to say both of us are excited for the idea of the real thing.
