This is a story about my first serious girlfriend. Her name was Emma. She was a petite Irish girl, everyone knew her for her glasses and her pair of big breasts. She was an incredibly smart girl. Shortly after we met she was an accepted MIT student so a smart one.

We had orbited each other for years in our church group and DnD sessions. After she broke up with a girlfriend she had in secret she quickly latched onto me. In hindsight I was a laughably obvious safety rebound. At the time though I had just got my first car and job and was brimming with a new found confidence.

We eventually lost our virginity to each other and again I felt like a conquering hero. For Emma 4 inches felt good when she had nothing to compare it to.

Come Summer some cracks started to show in her sexual interest. She grew tired of the same couple positions I could muster up. Missionary was fine but I would struggle to get into her with doggy. If I wasn't at complete 100 percent hardness forget it. Cowgirl, well I would slip out often...

Our relationship was still good nerdy fun though, bonding over Comics, Buffy, and DnD. One night I picked her up and as we where driving she told me about this guy who was hitting on her. I read the messages with him asking her to hook up.

Stupidly I take out my nub and send him a picture of it. "She's busy with me!" I actually messaged. I was so young, dumb, and full of cum that I actually thought sending him a picture of what is essentially a micropenis when soft was owning him.

He texted back "Aww that's cute."

I didn't think much of it, fumed a bit, but I was getting laid that night.

Two weeks later we drive to to a park and tells me that she can't keep up a lie anymore. She's been cheating on me. Not with just one guy but multiple. Of course worst of all. She's fucked the guy who I sent my tiny cock to.

I then have the indignity of driving her home with the image of him fucking her. Ill never know but I'm sure that he brought up the picture. How could he not?

At the time I was devastated. It shattered me. Now, I understand that she was looking trying to fill a void that a heterosexual relationship wouldn't fill.

Now I also get rock hard just thinking about that guy fucking her and cracking a joke about my self embarrassment.
