I ride my bike to work every day. For the record, I always wear a skirt to work. Before I set off I tilt my bike seat so it points straight up instead of forward. I put a condom on it, then I lower myself onto the seat so it penetrates me. I ride the whole way to work fully resting on the bike seat in my pussy, feeling the vibrations and every bump in the road. I try to avoid especially rough terrain but there's a patch halfway to work I can't avoid where I have to lift myself partway off the seat or it will hurt.

When I get to work I slip the condom off the seat and point it forward again, then I do the same thing on my way home from work. I've done this nearly every day for 3 years and none of my friends or coworkers has any idea.

I would like to get or make an actual dildo connected to a pole I could replace the seat with, or even better a full dildo bike (I have the one I want bookmarked. Peddling also makes a dildo piston through the seat.) but I can't afford either right now and even if I could I couldn't ride them to work without raising questions, but they would be fun to go riding at night at least.
