I love watersports too, however I have a cautionary tale to relate. It's one of those stories that's fucking hilarious when it happens to someone else, unfortunately, this happened to me...
It was last year sometime and I was meeting a well reviewed South American escort (who shall remain nameless) who's English was not the best but was perfectly serviceable.
On the phone call I confirmed that watersports would be available and was told it was no problem. Once we got the massage and a bit of mutual oral done I was horny as fuck so asked her could we do the watersports. Mmm hmm, she agreed. So, she put a towel down on the carpet and straddled over me. I was really getting into it as I love doing it on a towel, doing it in the bath isn't the best experience for me...
Anyway, she was squeezing for a few seconds and I had my mouth wide open for ready for it. When it eventually came I got this really strange taste in my mouth. It took me a few seconds to realise that she had taken a big sloppy crap.. I jumped up, ran into the bathroom and gagged my guts out, luckily only a small but had came out and I hadn't swallowed any of it but no matter how hard I tried I just couldn't get the taste out of my mouth.
Turns out she had misunderstood watersports and thought I wanted hardsports. I couldn't carry on so I got dressed and left. Bitch didn't even give me my money back!
So, there you go guys. All watersports lovers, make sure the girl knows what hole you're expecting it to come from!!
Anything's a dildo if you're brave enough.
