Getting Stared at On the bus

While on the bus (I am driving) I happened to have a hard on. I felt it grow out my boxers down my leg. I suddenly notice a woman next to me in the seat across the aisle glancing at me. I then realise my trousers are pulled tight and my hard cock is totally visible. As I noticed she was looking she saw I saw her looking so I spread my legs a little and laid the seat back a bit to give her a better view. When she thought I wasn't looking I noticed she was snapping pictures on her phone. This continued for the next 10 minutes or so, us throwing looks across at each other.
Then as she went to get off she got up out the seat ass facing me she pulls her already tight trousers tight up her arse to show off as much as she could she wiggled her way into them bouncing her arse up and down. Then walked off the bus swaying her hips, then before out of sight just looked back over her shoulder with a seductive look just to check if I was watching.

Damn it being such a busy bus with many other people getting off or I think we'd have ended up getting off.
