You want to end up with six girls? Cause that's how you end up with six girls.
The very first girl I banged, was catholic. I was 13, she was 14 when I first disappointed her sexually. We dated for about 2-3 years. She was one of 7 children at the time, I think it later became 9. Her mom had a boy from a previous marriage, she was her dad's first kid. Her dad insisted on having more and more kids in an attempt to have a boy of his own, but it wasn't in the cards. The youngest two when I was dating her were a pair of twin girls that were 3-5ish when we were dating. It was damn near impossible to find places to mess around with her at her house, we got busted by her sisters, constantly.
Her older half-brother was cool as shit. I stayed in touch with him long after I quit dating her. I also had the chance to bang her younger sister, in college, but passed on the opportunity. I will forever regret that decision.
