I don't know when it started. One day, I was the poster-boy for what a guy should be when dating a girl, the next, I was a womanizer.

I guess it happened when I realized I still hadn't lost my virginity despite dating my girlfriend for at least three years - it shocked me, and I wondered very briefly if my girlfriend was cheating on me with another guy - but I stopped that train of thought as soon as it began. If it was true, I didn't want to deal with it.

However, I am a teenage male, and I do get horny. It didn't surprise me when I began conjuring up images of other girls in my school and start fantasizing about fucking them.

I've always been into either small and perky tits or big (D Cup) and bouncy.

So there I was, fantasizing about girls other than my girlfriend when an opportunity rose up - a frat party invitation from my roommate.

It didn't take a moments' hesitation for me to answer...
