Some time ago I saw an ad for an online sex shop. While browsing through the entire online store, I came across a strap-on that wasn't expensive and at the same time looked quite functional.

It was a black latex penis with realistic veins. From the description I thought it would be a smaller dildo, but when I saw it for the first time I freaked out because it was practically the same size as my penis. I put it back in the box and forgot about it because I didn't think I could put something that big inside me.

I do play with my prostate from time to time, but I use slim anal plugs or a very thin flexible dildo.

Last night I smoked some weed and I like to clean up when I'm stoned. As I was tidying up, my girlfriend (F34) appeared in the doorway after coming home early from dinner with her friends.

Seeing her in a short skirt and black silk pants suddenly made my dick hard. My girlfriend was slightly drunk and when she found out I was high and horny she just smiled and obediently knelt down, pulled down my pants and started smoking deeply.

During the blowjob I was thought about how I was going to destroy her pussy today. First we started fucking standing up from behind, so I had a nice view of her anus as well.

My girlfriend rarely lets me fuck her butt - usually when she's drunk. I ran my thumb over her anus a few times, salivated, and slowly inserted the thumb into her back door - there was no negative reaction from her.

After moving to the couch, I continued fucking her pussy, looking forward to cumming in her asshole. But at that moment it occurred to me that today it might be the other way around!

I was so excited (and stoned) that I could barely speak, but I managed to ask her if she wanted to fuck me today instead of me fucking her.

I showed the strap-on to my girlfriend when I bought it and she was excited about it, but as she told me afterwards, she was waiting to see if I would have the courage to try it. And today I found the courage 😃.

I took out the strap-on with the gel and in a moment my beautiful, slim, tall girlfriend was standing in front of me with a black cock. I started kissing her and jerking her dick at the same time, not realizing that she couldn't feel it. I lubricated the dildo and my asshole. My girlfriend wanted to try doggy style first. So I got down on all fours and guided the latex cock into my anal sphincter.

My previous training with the smaller anal plugs really helped as the dildo passed through the sphincter quite easily and I began to feel the familiar sensation of something hitting my prostate. My girlfriend liked her new position very much, although it was obvious that she had no idea what she could afford and how far she could push.

My feelings were a mixture of extreme excitement with uncertainty about what my girlfriend would think of me. But here I was enjoying it very much, so I even began to moan.

After a while I needed to take a break. I was extremely horny, but I knew I wasn't going to cum in doggy style. After a short rest, I lay on my back, ready to be fucked missionary style by my beautiful girlfriend.

In this position, she also began to jerk off my penis. My excitement was growing and I didn't want to wait for anything, so I let my cum flow.

After the orgasm, I was lying on the couch all sticky with sperm, gel, pussy juice and saliva. It wasn't a real prostate orgasm but I felt extremely satisfied.

After the quick shower, my girlfriend and I discussed the whole experience in relative detail, as I was interested in her perspective on the experience. She said she had enjoyed it very much and was looking forward to doing it again. So I guess I should start with anal practice more.
