Bike Riding

I like to put a couple of marbles in my panties. Then I go for a long bike ride. The combination of my thighs in motion and the naughty thrill makes me very wet as I ride for an hour or so. I haven't developed an orgasm from it. I'm sure some women do. When I get home I enjoy lying in bed on my stomach and humping my pillow. The marbles rub my clit and give me a wonderful orgasm. Exercise is so much fun.
