undulate

The uncontrollable back and forth circular motions made by a woman's hips when her man has made her horny but is not there to satisfy her sexual cravings and NEEDS.

My hips undulate when I'm in the saddle, riding you.

My hips undulate wildly when you are far away and we have phone sex. That's phone fucking at it's best.

When you talk naughty to me like THAT, my ass take on a life of it's own, undulating relentlessly while your words make me cum over the phone. I quiver. I convulse, I spasm. I cum. Undulating ceases.

undulate

Verb. The act of urination.

Given because of the oscillating motion made by the penis upon the sucessful completion of a piss to dislodge any dewdrops.

The large phallus undulated a stream of hot liquid into her eyes.

You probably don't want to know, but it sounds like one of those words you learn in health class. Yeah.

We had to evacuate the pool because she undulated in it.
