I am an older guy (55) with a hot young girlfriend (23). The last couple of weekends she was with friends and I had been going up to the lake hanging out with the neighbors. If you haven't read those two stories, you may want too. But this weekend my gf wanted to hang with me and go shopping, she wanted a couple new pair of American Eagle Jeans. We have this rule, she can get anything she wants as long as she takes care of me sexually either in advance or afterwards. But this day, I came up with an idea to spice up our agreement a bit. As usual when we entered the store a few sales girls started making their way towards us. I guess it is known in the retail industry that if a hot young girl walks in with an older man and possible sugar daddy, they are going to buy things. I sat on a bench near the dressing rooms and waited for her to pick a few pair out. I didn't mind waiting as the employee monitoring the dressing room was a cute little brunette. She was dressed conservatively with a T-shirt, jeans and gym shoes. She was a little thick but I could tell had a nice body.

Finally, my girlfriend arrived with three pair of jeans. She asked the brunette if I could come back with her to the dressing room to see which pair I preferred. She said they weren't busy and to go ahead. I went back and sat in the small cubicle while she tried on the different styles. After going back to the sales floor a few times and continuing to try on different ones she finally decided on three pairs we both agreed upon. I asked her if she was sure and confirmed she wanted all three. Once she said yes, I reminded her of our shopping agreement and that we didn't have sex last night, nor could we tonight, due to it being a bad time of the month. She looked sadly down at the floor and apologized. 

I told her not to worry, I have a plan if she wants the jeans. She immediately looked up at me with big eyes and a smile and said okay, what is it? I told her she could drop to her knees and blow me right here right now. She giggled kind of nervously, asked I was serious and said she could do it tonight at home. I told her then we would have to leave without the jeans and try to find a time to come back later to get them. She laughed and told me no way, I want these today. I watched as she took her hairband off her arm and pulled her hair back in a ponytail. She knows from experience that keeps it out of the way and gives me something to hold onto while I guide her head. 

I stood and watched as she dropped to her knees and started to unbutton my shorts. She pulled my semi hard cock out and started to kiss and lick it. She was good at giving blow jobs because I had taught her well. Before long I was hard, she had both hands wrapped around it and was twisting as she sucked on the head. I looked up and noticed the curtain was slightly open. In the distance I could see the little brunette at the entrance to the dressing room area, oblivious to what we were doing. I watched as she sorted clothes and rehung them. Suddenly, she turned and started walking into the dressing area, as my girlfriend was masterfully blowing me with her back to the curtain. 

Just as the brunette was about five feet away, I grabbed my girlfriend's ponytail and told her to drop her hands. I started forcing her mouth onto my long thick rod. I moved her head back and forth going deeper with each push. Just as the brunette reached our room my girlfriend started to gag and choke. I watched as the employee passed our room but I heard her stop and saw her back up, glancing into our cubicle. I pretended not to see her as I told my girlfriend she was a good girl and she was doing a good job. I put both hands on her head and forced her all the way down, sliding my cock into her throat. I told her she must really want those jeans. I heard her try to respond but she could only mumble and gag. I knew she was trying to say yes, I love them, as this is a game we play anytime she's blowing me. I love to listen to her try and say she loves my dick while it is down her throat. 

I didn't move my head but I glanced towards the curtain. The brunette employee was still there watching, her eyes were wide with wonder. I released my girlfriend's head to let her catch her breath and she went right back to bobbing her head up and down on it. I told my girlfriend I was ready to cum, and she started moving faster. She was again mumbling, gagging and begging me to give it to her. I moaned as I started to shoot my load into her mouth. I immediately looked up at the young brunette and our eyes met. She tried to hide behind the curtain and move away. I heard her stumble over something as she continued down the hall. My girlfriend finished draining me and asked what that noise was. I told her I was unsure and she better get up and ready to go. I put my cock away as she straightened her hair and got the jeans she had just earned. 

I saw the brunette pass by going back to the front of the dressing rooms. Once we were ready, we exited the cubicle with the jeans and headed for the register. When we got to the brunette, she couldn't look at us so I told her my girlfriend found a few pair she really wanted. The employee barely got out a word, still not looking up at us. I motioned for my girlfriend to head for the register as I handed the brunette my card, without saying a word. When we got to the register, I looked back at the employee reading my card and watched her put it in her jeans' back pocket. I paid for my girl's jeans and we left going on to the next store. I hope the little brunette liked what she saw, wants to do the same thing and text me soon...
