HotPiston BlowBy
In her internal combustion engine, blow by is not easy or cheap and requires the continuous movement of hot pistons to push back and forth in the cylinder wall in order for it to happen.
HotPiston BlowBy happens when we ignite my girl's Internal combustion engine air and my HighOctane fuel. My explosion makes its way to her crankcase through the piston rings and orgasmic blow-by occurs, every time.
