Is it normal that my girl friend likes to give me handjobs in public?

My girl friend just love to whack off my cock in public places. Of course, the car is normal, but what about while eating in a nice restaurant? It was a good thing they had long table clothes.
One evening we visited her mom and watched a movie. Mom made us some popcorn and lit a fire in the fireplace. Suzan got a blanket to cover us, it was real cozy.
Then I felt a tugging at the buttons of my Levi's. I whispered to Suzan that this was not appropriate now, but she went ahead and yanked out my crank and started her majic. I got real pumped up and could not help my excitement from showing.
Then her Mom came out of the kitchen with some popcorn for us. She realized what was going on and pulled back the blanket as I was about to pop. She was really pissed off at the both of us, but especilly Suzan. She told Suzan to go get grandpa's razor strop out of the hallway closet. Suzan started to cry, but obeyed her Mom. I knew we were going to get the spankings of our lives, but I also knew we deserved it. Sure enough, we both were told to lower our blue jeans and under pants, and then bend ove the couch. Mom tanned our butts for 20 minutes and then sent us to bed in Suzan's old bedroom. My erection came back and this time Suzan wanted it where it belonged. She got on top of me and humped for an hour. She also still rubbed her bottom and moaned about the spankings we got. My buns were sore for a week but I was glad Suzan had learned her lesson. I let her continue her ways but reminded her when she wanted to go to far with it. I told her I would take her to her Mom's for a good licking if she did not behave. BTW- Suzan and I are both in our late 30's.
