I played like this for a few minutes and then lubed up the smallest dildo. It was probably 3 times bigger around than my finger so I used plenty of lube. Once lubed up, I reached behind me and slowly started to slide it into my ass. I have to admit it felt amazing as it slid in. I pushed it about half way in and then started to slide it in and out off my ass, putting more and more of its length in every few stokes. Soon enough I was all the way in and I was pumping it in and out of my ass while I stroked my cock with my other hand. I felt like I was about to cum a couple of times so I slowed down and let it pass. I knew I wouldn't be able to hold off much longer so I slid the dildo out of my ass and took a minute to calm down.
After a few minutes I was ready to resume my fun. I grabbed the largest dildo that was very close in size to the real cock that would be sliding into my ass soon enough. I noticed it had a suction cup on the end so I applied a bit of lube to that and stuck it to the cabinet. I lubed it up and then turned around started backing myself into it. Having it mounted to the cabinet helped a lot by allowing me to slowly work it into my ass. I relaxed by ass as much as I could and pushed out with my asshole a bit. As I pushed just a little more it popped into my ass with no pain at all.
Just having the large dildo in my ass gave me a huge amount of pleasure. I keep moving back and forth taking more and more of it inside me until finally I had the entire thing inside. At the same time I was stroking my cock. I concentrated on the feeling of my ass being penetrated and fantasized about it being a real cock. I started to move back and forth allowing the dildo to slide almost its entire length in and out of my ass. I then allowed it to completely come out of my ass and then immediately pushed it back it.
I continued to fuck myself like this for several minutes but finally gave in and allowed myself to explode. I shot a huge load of cum all over the towel. Reluctantly, I slide the dildo out of my ass and cleaned up my mess. I cleaned up all my toys and washed the towel so there was no evidence of what I had done.
I went upstairs, grabbed a cold beer and sat on the deck thinking about what my first time with a real cock was going to be like. I now knew I could take him in my ass without pain so I was anxious to experience the real thing. Sadly, it would be at least a week before that could happen.
