Mud Flaps

A very very very very old woman's vagina.
In other words, the vaginal lips are so old and saggy that they hang down like 2 mud flaps on a car.

I saw a pair of Mud Flaps walking down the street last night.

mud flaps

The luscious protruding inner lips of a woman's vagina which is men’s favorite part to suck on during oral sex.
These inner lips are particularly sensitive and touching them makes the woman orgasm.
The inner lips of some genetically blessed women grow larger during puberty.
The inner labia of the majority of women more or less protrude beyond the outer labia but since the protruding lips are considered too sexy (too graphic) for soft porn, the guidelines mandate digital removal of these parts before getting them published. So virgin guys who are used to jerking off to porn pussies are not aware of this trait of real-life pussies.

1.My girl’s mud flaps can kiss my dick at the same time she’s kissing my lips. It makes me and her madly horny!!!

2.I love rolling my wife’s mud flaps around in my mouth. Sucking on those juicy pussy-lips sends me and her to heaven!

3.Mike doesn’t know how sex works. I laughed so hard at that virgin dude when he said he thought girls can get their mud flaps stretched out during sex hahaaaaaa
