Erotic Couplings

This is my first story. It's mostly sex because that is what I like, but those of you who want a real plot with real characters may enjoy it too. This story involves: breast growth, penis growth, and extreme amounts of semen. For now it is all pretty vanilla but you can expect that to change in later installments. Feel free to copy this story and use it ho...

This has been written as a one-off while I write some more stories for Jason & Katie. This story is quite different to the 'Jason & Katie' stuff, but rest assured it still involves lots of hyper action! This one has some heavy BDSM elements, and has a pretty dark ending, so if that's not your thing then maybe skip this one. But if it sounds like you...

I was looking into the reason why the prostate gland would grow too large in male children who were given hormones to treat for under-developed penises. If I could find out why the prostate enlarged, I m...

Mark Holloway groaned as he sat up in bed and reached behind him to touch Madison. It was six o'clock on Saturday morning in Birmingham, Alabama.

She could do won...

After testing all of the exercise positions shown on the visual guide (particularly the sitting ones), I decided that the smaller machine suited my personal requirements the best. I particularly lik...
