The next day I stopped by the sex shop on the way home and bought some anal toys for us to play with. I would suggest at least at first only using toys that are produced for anal play as they usually have a wide base to assure they don't get lost inside the anal passage. She came home excited about taking that next step and was eager to start. After a repeat of our shower scene, I showed her my purchase. I again started with an oiled massage and after I got one finger in her, I tried two. She told me two fingers inside her was a different feeling from just one. As I spread them apart she could feel her rectum opening as I rubbed her inter wall. Next, I introduced one of the smaller toys I purchased and this was the first time we actually tried a fucking motion. As we worked in tandem, her pushing back to my pushing in I could tell she was really turned on by this.
The next toy we tried was a butt plug; this devise has a wide bulge just down from the tip. Once past the sphincter muscles the bulge gave her that full feeling that a cock gives but without a strain to her entrance. We had sex with the plug still inside her and believe me this was wild for both of us. Afterwards with the plug out she said her backside was a little sore but that she had enjoyed the feeling of being so full back there. She said she felt she was ready for the real thing and to be sure, I was too.
The next night was the big night and I found I was the one who was nervous, as she seemed calm and ready. I just didn't want to mess this up as I did the last time we tried it. We decided the way to be we sure we were working at a pace my girl would enjoy would be for me to be on the bottom and for her to lower her bum on to my cock. First, I oiled her rectum and then she did me. Both of us lubed and ready to go, I laid still and she slowly impaled herself on me. This gave her full control over both speed and depth. Once she got comfortable, she began to ride me and soon I was deep inside her with no pain at all.
We now consider back door loving as a special thing and we don't use it regularly. It is not something you should do on the spur of the moment or as a quickie. As my girlfriend is the only person I've ever had anal with, I couldn't say if my method of introducing it to her will work for you. I will say this no matter how you try it, take it slow to start with, and remember if it hurts, you are doing it wrong. One other thing when done right it really feels good.
