Cum at 15

I am called John and I have a disorder that means my testicles have grown to a massive size, so big that I worry I am a freak, I even have to have special underwear made to contain them comfortably. Another thing is that with them being so large it means I store a massive amount of cum in them, so much so in fact that I can almost produce enough to fill a two litre bottle, having tried to do so during masturbation, but my cum ran out as it got to 3 quarters full.
In fact the only thing I have been told that has a positive side is I have been informed by doctors I have a large chance of producing babies.

When I was 15 met a new girl at school called Lucy (also 15). Her body was heavenly she had a lovely round ass and B cup tits that complimented her body perfectly. The first time I saw her I almost came in my pants, I was desperate to become her friend and was lucky to have her in my class, so I set aside my testicular worries and resolved to sit next to her and talk to her.
She told me about the last school that she went to and then lent over to wisper in to my ear. I could feel her breast resting on my shoulder as he wispered in my ear.
“I fancy you, I have since the first day I saw you last week. I need you in my pussy.”
I told her I was a virgin and that I had only fingered a girl before, and she told me that I didn’t have to worry.

We organised a time to meet up that night, and at six o’clock she knocked on my door.
“Where are we going to go, my pussy is so wet.”
I took her hand and led her down the road near my house to a disused railway, I took her down underneath the bridge.
As soon as we got there she pushed me against the wall and pushed her lips against mine, I let her tongue into my mouth and one of the best feelings I had ever had washed over my body.
