I just watched a video called "Black Dick Too Boo Coo 3" where Dawn Ivy (formerly known as Cris Taliana) had one of the best, most intense and uncontrollable orgasms that I've seen all year.
The great thing about it was that she had it while fucking, which is hard to find (unless the girl is Cytherea). Most orgasms that intense I've seen usually involve a vibrator, hand or tongue.
