To preface I am a male so this will probably get taken down.

I have a small dick and in a relationship. It turns me on to fantasize about a longer thicker cock destroying my girlfriend.

She is very supportive of my dick size insecurity and says size never mattered to her. She is super sweet and kind.

But my fantasy invovles her being proved wrong. In my fantasy I want her to realize that size does matter when the big cock stretches her out and goes really deep in her.

That look in her eye when the sensation of something better goes in her and she realizes that she was completely wrong. The sensation takes over her and becomes a complete slut.

I fantasize about the woman I love who is supportive and mindful become addicted to big dick and humiliates me and become a slut.
