The last couple of summers I've cycled to college and around my semi rural home, using my addition to the bicycle seat. It's easy to attach and remove so I have no fear of being caught out, and I get and have so many and such strong orgasms from using it.
The attachment is a dildo I've had a couple of clips and ties attached to. It fits over my bicycle seat and it's really firmly in place when I mount it to ride to college or around the lanes close my home. The dildo is a six inch one, which is also quite thick. I always wear long flowing loose skirts which cover my modesty and never wear knickers.
Each time I use it, I get amazing climaxes from being fucked without people knowing I'm having sex with my bicycle.
I've even stopped on the lanes close by my home, with it deeply embedded up my pussy or arsehole, and given out directions to motorists who are lost.
College is a little trickier, as I have to time it so I arrive when no one is around near the cycle sheds, but so far I've accomplished it without anyone finding out about my fetish.
My boyfriend doesn't even know as I've kept it from him. I tell myself it's because I don't want to hurt him, but in realty, I think it's because I secretly want to be caught and fucked by strangers, especially older men.
