I went looking around and after a while some men came in some looking at books some going to the back. I just keep walking around the store and even g...tting into a couple of conversations with the desk man and some other man, may me feel better about myself and what I wanted to do in the back.After a while I again went to the back this time I did not go in a booth, I just walk to the second one with the curtain closed and slowly pulled it back and looked in. The man was about my age, in dress. I jerked at the contact of her tongue just under my head and she smiled. “Good one, huh?” she asked.“Absolutely fucking amazing.” I answered.“Yeah, that was fucking spectacular for me, too. I didn’t think I would be able to keep my ass up in the air for those truckers, but it turned me on tremendously.”“I could tell” I told her. “I thought you were going to have my dick for dinner.”She laughed. “It was pretty fucking tasty with my juices running all the way down your balls.”“Yeah, and I’m going. I still kept eyes closed.Then I heard her open the bathroom door. It was about 2 minutes I have been keeping my eyes closed with my erect cock in air. All of a sudden I opened my eyes and found my sister staring at my cock. She noticed me open my eyes and gave me a smile. I said sorry and told that I was not aware of her presence and acted to be feeling shy. I covered my dick and came out of the bathroom. But she kept smiling.Day 2:I was sure that my plan is going to work. It was a great day.. And, what’s worse, I can’t just tell them ‘hell no!’; I have to explain tactfully exactly why it can’t be done, or why we’ve chosen not to go down that path. Oh, occasionally one of them picks up a darned good thing, but ... not that often. Today was no exception to the rule.By the time I’d gotten him off the line, I’d missed the start on the rush. Heck, it took five minutes to exit from the parking structure, I was behind so many people!Was I nervous about seeing Mel? You bet. I felt some.
