Cervical Orgasm; stroking the cervix.

My wife achieves the ultimate orgasm during cervical stimulation. She enjoys being penetrated deep by my long 10" penis, she finds that the best method is to rub her cervix with the tip of my glans using three techniques;
1. touching her cervix with the tip of my glans, thrusting deeply and firmly into her vagina with a repetitive in and out motion maintained for a long time.
2. Moving her vagina back and forth, so that my glans flips her cervix back and forth.
3. moving her pussy in a circular motion whilst riding me cowgirl so that my glans rotates internally around her cervix.
She prefers a hard pounding repetitive motion that continues for a long time. The continuous stimulation is enough to allow her to achieve orgasms up to an hour after fucking. i am going to try fucking her for up to three hours so that she can maintain continuous orgasms.
Felling my penis touch the cervix is intensely enjoyable, i like to feel the opening in the tip of my glans touching her soft surface and exploring the entrance to the cervix. During ejaculation i hold the opening of my glans next to the cervix hole, this way i can squirt semen directly through her cervix into her uterus. This she find intense, describing it as being showered by glittering stars. I like to continue pumping semen thru the cervix hole, holding it close, until all sperm has been pumped into the uterus. I like to hold my penis inside as long as possible.
Repeat the process as much as possible, each time is more intense.
