Your friend was so nervous when he invited you over after school.
"Sorry about my mom in advance," he says, stuttering, "she can get kinda...intense."
Boy. You had no idea. She started off flirty, yeah, but you're handsome, and pretty jacked, so older women throwing themselves at you isn't totally new. You've never moved on it, though...too shy, you guess. But there's no need to worry here! Your friend's MILF goes into great detail about all the young men she fucks--bullies, mostly--to keep her boy protected, to get him better grades, to keep him from having to do too much in PE...but you know its not just for his benefit.
The way she gets on her knees and pulls your cock out, the gleam in her eye...well, she can make all the excuses in the world for what a wanton slut she is, but the truth is that she just plain loves it. Even having her sweet boy watch! She loves that too. Loves humiliating him just a little bit, playfully, her mouth stretched and drooling. God, you think you just found your new best friend!
