I was sitting on the bench and slowly diddling myself.  Unbeknownst to me, the waitress came from behind me and caught me with my legs spread wide and my fingers deep in my pussy.   I turned suddenly away from her when I noticed she was there, pretending to get something out of my purse.  The action moved my dress to partially cover me, but not fully, and I'm pretty sure she could still see my crotch and stocking tops.  She handed us the menus, and started talking about the specials.  As I reached for the menu you could see my hand was covered with my juice.  There were strings hanging between my index finger and thumb.  WOW...was I embarrassed.  Nothing else much happened through the remainder of dinner.  I didn't finish didling myself, I would have to wait for Don to eat me later.  There was a brief akward moment when I got out of the booth when my dress got caught as I turned to step out.  Again, I was full exposed from my belly downward.  The couple across from us got another eyeful and as I turned to leave, I heard thr man across from us say "very Nice".  His female companion hit him...

When we got to the parkinglot, Don opened the back door of the car.  He told me to remove the dress and get in the back seat.  It was a very crowded parking lot, and with it being dark, you couldn't really see if anyone was in their cars nearby.  I anxiously looked all around me and then I took the dress off and very reluctantly handed it to Don.  He closed the door and walked to the other side of the car, and got in the back seat as well.  He opened his pants and pulled them down around his ankles.  I knew right away what he was wanting and I repositioned myself so I could take him in my mouth.  My right knee was on the bench seat and my left sort of kneeling on the floor of the car.  My big butt was facing the window and my legs were spread enough that if you were looking in the window, you could see my bush.  I started sucking his cock very slowly.  One of the things I love about blowjobs is feeling him get hard in my mouth while I suck.  He reached his left hand around to my butt and found the princess plug.  "What a very good girl you are for giving me this surprise" he said.  He started to pull the plug, but it was dry and it hurt a little as he pulled it out.  He told me to stop sucking him for a moment and then he told me to put the plug in my mouth to lubricate it.  Not one of my favorite things to do, but I knew my butt was clean, so it didn't bother me too much.  I spit on it, sucked on it, and spit on it again.  Don took it and slide it back into my butt.  Oh what a marvelous feeling when the wide part of the bulb fully stretches my ass open.  I love that sensation.  I went back to sucking Don's cock, and felt him pulling the plug against the rectum muscle.  That tugging sends me through the roof, especially when he is licking my clit.   I could feel him getting close and could hear his breathing getting shallower.  I deliberatly slowed down and flicked my tongue at the crown of his cock.  I would do this sort of pattern when I knew he was close, so I could prolong and delay his orgasm.  I would slide my mouth back down his shaft all the way to his balls, then slowly come back up.  Depending on how close I thought he was, I would usually do this three or four times, then flick the crown of his cock.  Each pass, I would shorten the number of times I took him fully in my mouth.  On the third pass, he grunted and shot his load into my mouth.  It was very warm and salty, but I didn't swallow.  Don loves to see me open my mouth with his load of cum and display it on my tongue.  When he finally stopped convulsing, I lifted my head and opened my mouth showing him the cum he had just deposited.  I spit the cum out of my mouth, so that it dripped down my chin and onto my tits.  He always loves seeing that.  We sat for a few moments collecting ourselves.  Don pulled his pants back up, and got out of the car.  He walked around to my side and opened the door for me, and that's when I noticed that both the cars parked on either side of us were gone.  I hope we gave them a good show.  I put the dress back on but didn't button it up.  I then walked around to the passenger side with my dress wide open and got in the front seat.  I rode home with the dress fully open.
