This has to be why Women Ride Guys for Fun.

When do women start experimenting with masturbatory stimulation? Even though most are believed to start out at a very developing age, approximately 13 years old, one can find exceptions of older women starting in their 30s, and 40s. Exactly like for guys, masturbation for girls is typically discovered by accident, but then carries on to be practiced intentionally. Because most first times of genital masturbation for females occurs while they are in their beds, most women become imaginative with masturbation routines also, while they are in bed. When women discover that the pillow they sleep on offers such extraordinary pleasures and feelings when placed between their legs and made love to. If they ever thought it was easy and wanted to know how to ride a guy then they shouldn't even look too far. They usually never return to any other methods of self pleasuring. In addition to bedrooms, camping in sleeping bags, and sleeping at motels, have also been places girls have stated to have masturbated with a pillow for the first time. After a girl realizes the sexual pleasure obtained from rubbing her clitoris backwards and forwards on her pillow, the woman will continue to do so out of curiosity of what can happen. And to gauge how high her arousal level can get to. After attaining a elevated pleasurable position, several women have said they had to force themselves to stop humping their pillow. On the other hand, many others have stated they kept moving until eventually they achieved ejaculation. The women that cease masturbating when hitting a elevated amount of pleasure often times claim that they just could not take the increased amount of excitement they were experiencing. The girls that report going forward through the activity report having the very best orgasms they have ever been through.

Looks like fun.
