A'ja had a reputation of being a "Freak between the sheets," and although it was assumed she had a high body count, she was very discrete.
You heard the stories of guys that you know we're left crying on a bench when she broke up with them. A friend, who got locked up twice because he confronted her about alleged infidelity. Even a family member who would lose sleep to "hookup" with her when she would call him in the middle of the night.
Now, she's being "flirty" with you. She has no idea your somewhat familiar with her past. However, are you going to be part of her future?
