So... cumbaths and filling creampies eh?  What a dirty little girl... she was keeping her!  And with how anxious the woman was... hm... perhaps she had an idea.  She reduced the size of the cock - but not the balls, not yet - down to about... nine inches, though a couple inches thick, but both definitely withing normal human limits.  Taking one hand off the wheel for a moment, she stroked her stiff meat a couple of times, and then turned a bit to as if to present her girth to the other woman in the car, a truly lewd grin plastered on her face.<br/><br/>"You look like you need<em>something</em>." she cooed, and then gestured down at the cock "I can drive and take a good sucking at the same time, I promise.  Besides, think of it as a game; we'll be 'home' in five minutes... see if you can make me cum before then and drink down these bull-balls and fill your belly!  Don't want to make a mess in my car after all..."
