Grinding...yeah!!!!

Alright, so just like almost any weekend here at college, I go out just like any other person and drink until my heart is hearty.
At the parties I go to, there always has to be dancing.
And when there is dancing, there is grinding. It's just a matter of who dances with who.

Now, every time I do grind with a chick, my little friend down south gets a little bigger and harder.
I know it is normal because if you can't feel a chick's ass rubbing on you, then there is definitely something wrong with your d***.

I just want to know if girls like it when they feel something. So is it normal to keep continuing with a hard one?
