Been there done that. Enjoy the pu$$y.
But a word of caution: Most single mothers are desperate to find a man to take care of their little "mistakes". Of course if you told this to any single mothers they would scoff and shake their heads and tell you that you're crazy. Bullshyt!
Because they know they're damaged goods, they will try to impress you in ways that women without kids never would.
Now what does this have to do with you, you say? You just want to "hit it and quit it". Yes my friend, you SAY that. But believe me, she will be the BEST girl you've ever been with. She'll treat you like a friggin' king. Maybe buy you stuff. You might start saying to yourself "Hey, this isn't so bad after all. Maybe I'll just bang her a couple more months...."
Boom! That's the trap dude. After they have you(preferably by getting pregnant from you). You will see their true self emerge, and it's usually not pretty.
When I was younger I went through hell with a woman that had 2 kids from different men. She would bend over backwards for me...for the first little while that is. This girl would buy EVERYTHING. Let me do things to her in the bedroom that would make Ron Jeremy blush. Luckily I didn't get her pregnant, but believe me, she was trying to.
Just a little word of caution. Dating a single mother almost ruined my life. Be careful.
