Knickerless Drive

As it's so hot, I've been loungeing around the house with just a tee shirt. (Can't be naked because house is overlooked).  Decided for first time ever to venture out dressed just like that.  Drove to the car wash with shirt pulled down, but increasing erection.  On the way back drove along the sea front and wanked gently as I drove.  So exciting to think anyone glancing in could have seen me.  

Great cum!  Tee shirt soaked.  Even the walk from car to house was a turn on.  Must try again soon!
