A very vulgar joke!

I recall my first time with a condom....I was 16 or so. I went in tobuy a package of condoms. There was a beautiful woman behind thecounter and, she could see that I was new at it.She handed me the package and asked if I knew how to wear one.I honestly answered, "No."So she unwrapped the package, took one out, and slipped over herthumb. She cautioned me to make sure it was on tight and secure. Iapparently still looked confused so, she looked all around the store.It was empty. She said, "Just a minute, " and walked to the door andlocked it.Taking my hand, she led me into the back room, unbuttoned her blouse,and removed it. She unhooked her bra and laid it aside. She asked,"Do these excite you?"Well, I was SO dumb-struck that all I could do was nod my head.She then said it was time to slip the condom on. As I was slipping iton, she dropped her skirt, removed her panties, and laid down on adesk."Well, come on, " she said, "we don't have much time."So I climbed on her. It was so wonderful that, unfortunately, I couldno longer hold back and..........POW, I was done within a few minutes.She looked at me with a frown. "Did you put that condom on?" Isaid, "I sure did, " and held up my thumb to show her.
